How Payment for Order Flow (PFOF) Works
What is PFOF?
PFOF is a brokerage firm's compensation for directing orders to different parties for trade execution. The brokerage firm receives fractions of a penny per share for directing the order to a market maker.
Each optionable stock could have thousands of contracts, so market makers dominate options trades. Order flow payments average less than $0.50 per option contract.
Order Flow Payments (PFOF) Explained
The proliferation of exchanges and electronic communication networks has complicated equity and options trading (ECNs) Ironically, Bernard Madoff, the Ponzi schemer, pioneered pay-for-order-flow.
In a December 2000 study on PFOF, the SEC said, "Payment for order flow is a method of transferring trading profits from market making to brokers who route customer orders to specialists for execution."
Given the complexity of trading thousands of stocks on multiple exchanges, market making has grown. Market makers are large firms that specialize in a set of stocks and options, maintaining an inventory of shares and contracts for buyers and sellers. Market makers are paid the bid-ask spread. Spreads have narrowed since 2001, when exchanges switched to decimals. A market maker's ability to play both sides of trades is key to profitability.
Benefits, requirements
A broker receives fees from a third party for order flow, sometimes without a client's knowledge. This invites conflicts of interest and criticism. Regulation NMS from 2005 requires brokers to disclose their policies and financial relationships with market makers.
Your broker must tell you if it's paid to send your orders to specific parties. This must be done at account opening and annually. The firm must disclose whether it participates in payment-for-order-flow and, upon request, every paid order. Brokerage clients can request payment data on specific transactions, but the response takes weeks.
Order flow payments save money. Smaller brokerage firms can benefit from routing orders through market makers and getting paid. This allows brokerage firms to send their orders to another firm to be executed with other orders, reducing costs. The market maker or exchange benefits from additional share volume, so it pays brokerage firms to direct traffic.
Retail investors, who lack bargaining power, may benefit from order-filling competition. Arrangements to steer the business in one direction invite wrongdoing, which can erode investor confidence in financial markets and their players.
Pay-for-order-flow criticism
It has always been controversial. Several firms offering zero-commission trades in the late 1990s routed orders to untrustworthy market makers. During the end of fractional pricing, the smallest stock spread was $0.125. Options spreads widened. Traders found that some of their "free" trades cost them a lot because they weren't getting the best price.
The SEC then studied the issue, focusing on options trades, and nearly decided to ban PFOF. The proliferation of options exchanges narrowed spreads because there was more competition for executing orders. Options market makers said their services provided liquidity. In its conclusion, the report said, "While increased multiple-listing produced immediate economic benefits to investors in the form of narrower quotes and effective spreads, these improvements have been muted with the spread of payment for order flow and internalization."
The SEC allowed payment for order flow to continue to prevent exchanges from gaining monopoly power. What would happen to trades if the practice was outlawed was also unclear. SEC requires brokers to disclose financial arrangements with market makers. Since then, the SEC has watched closely.
2020 Order Flow Payment
Rule 605 and Rule 606 show execution quality and order flow payment statistics on a broker's website. Despite being required by the SEC, these reports can be hard to find. The SEC mandated these reports in 2005, but the format and reporting requirements have changed over the years, most recently in 2018.
Brokers and market makers formed a working group with the Financial Information Forum (FIF) to standardize order execution quality reporting. Only one retail brokerage (Fidelity) and one market maker remain (Two Sigma Securities). FIF notes that the 605/606 reports "do not provide the level of information that allows a retail investor to gauge how well a broker-dealer fills a retail order compared to the NBBO (national best bid or offer’) at the time the order was received by the executing broker-dealer."
In the first quarter of 2020, Rule 606 reporting changed to require brokers to report net payments from market makers for S&P 500 and non-S&P 500 equity trades and options trades. Brokers must disclose payment rates per 100 shares by order type (market orders, marketable limit orders, non-marketable limit orders, and other orders).
Richard Repetto, Managing Director of New York-based Piper Sandler & Co., publishes a report on Rule 606 broker reports. Repetto focused on Charles Schwab, TD Ameritrade, E-TRADE, and Robinhood in Q2 2020. Repetto reported that payment for order flow was higher in the second quarter than the first due to increased trading activity, and that options paid more than equities.
Repetto says PFOF contributions rose overall. Schwab has the lowest options rates, while TD Ameritrade and Robinhood have the highest. Robinhood had the highest equity rating. Repetto assumes Robinhood's ability to charge higher PFOF reflects their order flow profitability and that they receive a fixed rate per spread (vs. a fixed rate per share by the other brokers).
Robinhood's PFOF in equities and options grew the most quarter-over-quarter of the four brokers Piper Sandler analyzed, as did their implied volumes. All four brokers saw higher PFOF rates.
TD Ameritrade took the biggest income hit when cutting trading commissions in fall 2019, and this report shows they're trying to make up the shortfall by routing orders for additional PFOF. Robinhood refuses to disclose trading statistics using the same metrics as the rest of the industry, offering only a vague explanation on their website.
Summary
Payment for order flow has become a major source of revenue as brokers offer no-commission equity (stock and ETF) orders. For retail investors, payment for order flow poses a problem because the brokerage may route orders to a market maker for its own benefit, not the investor's.
Infrequent or small-volume traders may not notice their broker's PFOF practices. Frequent traders and those who trade larger quantities should learn about their broker's order routing system to ensure they're not losing out on price improvement due to a broker prioritizing payment for order flow.

How to Make a Trading Heatmap
Python Heatmap Technical Indicator
Heatmaps provide an instant overview. They can be used with correlations or to predict reactions or confirm the trend in trading. This article covers RSI heatmap creation.
The Market System
Market regime:
Bullish trend: The market tends to make higher highs, which indicates that the overall trend is upward.
Sideways: The market tends to fluctuate while staying within predetermined zones.
Bearish trend: The market has the propensity to make lower lows, indicating that the overall trend is downward.
Most tools detect the trend, but we cannot predict the next state. The best way to solve this problem is to assume the current state will continue and trade any reactions, preferably in the trend.
If the EURUSD is above its moving average and making higher highs, a trend-following strategy would be to wait for dips before buying and assuming the bullish trend will continue.
Indicator of Relative Strength
J. Welles Wilder Jr. introduced the RSI, a popular and versatile technical indicator. Used as a contrarian indicator to exploit extreme reactions. Calculating the default RSI usually involves these steps:
Determine the difference between the closing prices from the prior ones.
Distinguish between the positive and negative net changes.
Create a smoothed moving average for both the absolute values of the positive net changes and the negative net changes.
Take the difference between the smoothed positive and negative changes. The Relative Strength RS will be the name we use to describe this calculation.
To obtain the RSI, use the normalization formula shown below for each time step.
The 13-period RSI and black GBPUSD hourly values are shown above. RSI bounces near 25 and pauses around 75. Python requires a four-column OHLC array for RSI coding.
import numpy as np
def add_column(data, times):
for i in range(1, times + 1):

elif data[i, position] < 0:

data = smoothed_ma(data, 2, lookback, position + 1, position + 3)
data = smoothed_ma(data, 2, lookback, position + 2, position + 4)
data[:, position + 5] = data[:, position + 3] / data[:, position + 4]
data[:, position + 6] = (100 - (100 / (1 + data[:, position + 5])))
data = delete_column(data, position, 6)
data = delete_row(data, lookback)

My weekly market sentiment report uses complex and simple models to understand the current positioning and predict the future direction of several major markets. Check out the report here:
Using the Heatmap to Find the Trend
RSI trend detection is easy but useless. Bullish and bearish regimes are in effect when the RSI is above or below 50, respectively. Tracing a vertical colored line creates the conditions below. How:
When the RSI is higher than 50, a green vertical line is drawn.
When the RSI is lower than 50, a red vertical line is drawn.
Zooming out yields a basic heatmap, as shown below.
Plot code:
def indicator_plot(data, second_panel, window = 250):
fig, ax = plt.subplots(2, figsize = (10, 5))
sample = data[-window:, ]
for i in range(len(sample)):
ax[0].vlines(x = i, ymin = sample[i, 2], ymax = sample[i, 1], color = 'black', linewidth = 1)
if sample[i, 3] > sample[i, 0]:
ax[0].vlines(x = i, ymin = sample[i, 0], ymax = sample[i, 3], color = 'black', linewidth = 1.5)
if sample[i, 3] < sample[i, 0]:
ax[0].vlines(x = i, ymin = sample[i, 3], ymax = sample[i, 0], color = 'black', linewidth = 1.5)
if sample[i, 3] == sample[i, 0]:
ax[0].vlines(x = i, ymin = sample[i, 3], ymax = sample[i, 0], color = 'black', linewidth = 1.5)
ax[0].grid()
for i in range(len(sample)):
if sample[i, second_panel] > 50:
ax[1].vlines(x = i, ymin = 0, ymax = 100, color = 'green', linewidth = 1.5)
if sample[i, second_panel] < 50:
ax[1].vlines(x = i, ymin = 0, ymax = 100, color = 'red', linewidth = 1.5)
ax[1].grid()
indicator_plot(my_data, 4, window = 500)
Call RSI on your OHLC array's fifth column. 4. Adjusting lookback parameters reduces lag and false signals. Other indicators and conditions are possible.
Another suggestion is to develop an RSI Heatmap for Extreme Conditions.
Contrarian indicator RSI. The following rules apply:
Whenever the RSI is approaching the upper values, the color approaches red.
The color tends toward green whenever the RSI is getting close to the lower values.
Zooming out yields a basic heatmap, as shown below.
Plot code:

Dark green and red areas indicate imminent bullish and bearish reactions, respectively. RSI around 50 is grey.
Summary
To conclude, my goal is to contribute to objective technical analysis, which promotes more transparent methods and strategies that must be back-tested before implementation.
Technical analysis will lose its reputation as subjective and unscientific.
When you find a trading strategy or technique, follow these steps:
Put emotions aside and adopt a critical mindset.
Test it in the past under conditions and simulations taken from real life.
Try optimizing it and performing a forward test if you find any potential.
Transaction costs and any slippage simulation should always be included in your tests.
Risk management and position sizing should always be considered in your tests.
After checking the above, monitor the strategy because market dynamics may change and make it unprofitable.

Donor-Advised Fund Tax Benefits (DAF)
Giving through a donor-advised fund can be tax-efficient. Using a donor-advised fund can reduce your tax liability while increasing your charitable impact.
Grow Your Donations Tax-Free.
Your DAF's charitable dollars can be invested before being distributed. Your DAF balance can grow with the market. This increases grantmaking funds. The assets of the DAF belong to the charitable sponsor, so you will not be taxed on any growth.
Avoid a Windfall Tax Year.
DAFs can help reduce tax burdens after a windfall like an inheritance, business sale, or strong market returns. Contributions to your DAF are immediately tax deductible, lowering your taxable income. With DAFs, you can effectively pre-fund years of giving with assets from a single high-income event.
Make a contribution to reduce or eliminate capital gains.
One of the most common ways to fund a DAF is by gifting publicly traded securities. Securities held for more than a year can be donated at fair market value and are not subject to capital gains tax. If a donor liquidates assets and then donates the proceeds to their DAF, capital gains tax reduces the amount available for philanthropy. Gifts of appreciated securities, mutual funds, real estate, and other assets are immediately tax deductible up to 30% of Adjusted gross income (AGI), with a five-year carry-forward for gifts that exceed AGI limits.
Using Appreciated Stock as a Gift
Donating appreciated stock directly to a DAF rather than liquidating it and donating the proceeds reduces philanthropists' tax liability by eliminating capital gains tax and lowering marginal income tax.
In the example below, a donor has $100,000 in long-term appreciated stock with a cost basis of $10,000:
Using a DAF would allow this donor to give more to charity while paying less taxes. This strategy often allows donors to give more than 20% more to their favorite causes.
For illustration purposes, this hypothetical example assumes a 35% income tax rate. All realized gains are subject to the federal long-term capital gains tax of 20% and the 3.8% Medicare surtax. No other state taxes are considered.

📖 Guide to NFT terms: an NFT glossary.
NFT lingo can be overwhelming. As the NFT market matures and expands so does its own jargon, slang, colloquialisms or acronyms.
This ever-growing NFT glossary goal is to unpack key NFT terms to help you better understand the NFT market or at least not feel like a total n00b in a conversation about NFTs on Reddit, Discord or Twitter.
#
1:1 Art
Art where each piece is one of a kind (1 of 1). Unlike 10K projects, PFP or Generative Art collections have a cap of NFTs released that can range from a few hundreds to 10K.
1/1 of X
Contrary to 1:1 Art, 1/1 of X means each NFT is unique, but part of a large and cohesive collection. E.g: Fidenzas by Tyler Hobbs or Crypto Punks (each Punk is 1/1 of 10,000).
10K Project
A type of NFT collection that consists of approximately 10,000 NFTs (but not strictly).
A
AB
ArtBlocks, the most important platform for generative art currently.
AFAIK
As Far As I Know.
Airdrop
Distribution of an NFT token directly into a crypto wallet for free. Can be used as a marketing campaign or as scam by airdropping fake tokens to empty someone’s wallet.
Alpha
The first or very primitive release of a project. Or Investment term to track how a certain investment outdoes the market. E.g: Alpha of 1.0 = 1% improvement or Alpha of 20.0 = 20% improvement.
Altcoin

Ape
Someone can be aping, ape in or aped on an NFT meaning someone is taking a large position relative to its own portfolio size. Some argue that when someone apes can mean that they're following the hype, out of FOMO or without due diligence. Not related directly to the Bored Ape Yatch Club.
ATH
All-Time High. When a NFT project or token reaches the highest price to date.
Avatar project
An NFT collection that consists of avatars that people can use as their profile picture (see PFP) in social media to show they are part of an NFT community like Crypto Punks.
Axie Infinity
ETH blockchain-based game where players battle and trade Axies (digital pets). The main ERC-20 tokens used are Axie Infinity Shards (AXS) and Smooth Love Potions (formerly Small Love Potion) (SLP).
Axie Infinity Shards
AXS is an Eth token that powers the Axie Infinity game.
B
Bag Holder
Someone who holds its position in a crypto or keeps an NFT until it's worthless.
BAYC
Bored Ape Yacht Club. A very successful PFP 1/1 of 10,000 individual ape characters collection. People use BAYC as a Twitter profile picture to brag about being part of this NFT community.

Burn
Common crypto strategy to destroy or delete tokens from the circulation supply intentionally and permanently in order to limit supply and increase the value.
Buying on secondary
Whenever you don’t mint an NFT directly from the project, you can always buy it in secondary NFT marketplaces like OpenSea. Most NFT sales are secondary market sales.
C
Cappin or Capping
Slang for lying or faking. Opposed to no cap which means “no lie”.
Coinbase
Nasdaq listed US cryptocurrency exchange. Coinbase Wallet is one of Coinbase’s products where users can use a Chrome extension or app hot wallet to store crypto and NFTs.
Cold wallet
Otherwise called hardware wallet or cold storage. It’s a physical device to store your cryptocurrencies and/or NFTs offline. They are not connected to the Internet so are at less risk of being compromised.
Collection
A set of NFTs under a common theme as part of a NFT drop or an auction sale in marketplaces like OpenSea or Rarible.
Collectible
A collectible is an NFT that is a part of a wider NFT collection, usually part of a 10k project, PFP project or NFT Game.
Collector
Someone who buys NFTs to build an NFT collection, be part of a NFT community or for speculative purposes to make a profit.
Cope
The opposite of FOMO. When someone doesn’t buy an NFT because one is still dealing with a previous mistake of not FOMOing at a fraction of the price. So choosing to stay out.
Consensus mechanism

Cozomo de’ Medici
Twitter alias used by Snoop Dogg for crypto and NFT chat.
Creator
An NFT creator is a person that creates the asset for the NFT idea, vision and in many cases the art (e.g. a jpeg, audio file, video file).
Crowsale
Where a crowdsale is the sale of a token that will be used in the business, an Initial Coin Offering (ICO) is the sale of a token that’s linked to the value of the business. Buying an ICO token is akin to buying stock in the company because it entitles you a share of the earnings and profits. Also, some tokens give you voting rights similar to holding stock in the business. The US Securities and Exchange Commission recently ruled that ICOs, but not crowdselling, will be treated as the sale of a security. This basically means that all ICOs must be registered like IPOs and offered only to accredited investors. This dramatically increases the costs and limits the pool of potential buyers.
Crypto Bags/Bags
Refers to how much cryptocurrencies someone holds, as in their bag of coins.
Cryptocurrency
The native coin of a blockchain (or protocol coin), secured by cryptography to be exchanged within a Peer 2 Peer economic system. E.g: Bitcoin (BTC) for the Bitcoin blockchain, Ether (ETH) for the Ethereum blockchain, etc.

Crypto exchange
Where someone can buy, sell or trade cryptocurrencies and tokens.
Cryptography

CryptoKitties
One of the first and most popular NFT based blockchain games. In 2017, the NFT project almost broke the Ethereum blockchain and increased the gas prices dramatically.
CryptoPunk
Currently one of the most valuable blue chip NFT projects. It was created by Larva Labs. Crypto Punk holders flex their NFT as their profile picture on Twitter.
CT
Crypto Twitter, the crypto-community on Twitter.
Cypherpunks
Movement in the 1980s, advocating for the use of strong cryptography and privacy-enhancing technologies as a route to social and political change. The movement contributed and shaped blockchain tech as we know today.
D
DAO
Stands for Decentralized Autonomous Organization. When a NFT project is structured like a DAO, it grants all the NFT holders voting rights, control over future actions and the NFT’s project direction and vision. Many NFT projects are also organized as DAO to be a community-driven project.
Dapp
Mobile or web based decentralized application that interacts on a blockchain via smart contracts. E.g: Dapp is the frontend and the smart contract is the backend.
DCA
Acronym for Dollar Cost Averaging. An investment strategy to reduce the impact of crypto market volatility. E.g: buying into a crypto asset on a regular monthly basis rather than a big one time purchase.
Ded
Abbreviation for dead like "I sold my Punk for 90 ETH. I am ded."
DeFi
Short for Decentralized Finance. Blockchain alternative for traditional finance, where intermediaries like banks or brokerages are replaced by smart contracts to offer financial services like trading, lending, earning interest, insure, etc.
Degen
Short for degenerate, a gambler who buys into unaudited or unknown NFT or DeFi projects, without proper research hoping to chase high profits.
Delist
No longer offer an NFT for sale on a secondary market like Opensea. NFT Marketplaces can delist an NFT that infringes their rules. Or NFT owners can choose to delist their NFTs (has long as they have sufficient funds for the gas fees) due to price surges to avoid their NFT being bought or sold for a higher price.
Derivative
Projects derived from the original project that reinforces the value and importance of the original NFT. E.g: "alternative" punks.
Dev
A skilled professional who can build NFT projects using smart contracts and blockchain technology.
Dex
Decentralised Exchange that allows for peer-to-peer trustless transactions that don’t rely on a centralized authority to take place. E.g: Uniswap, PancakeSwap, dYdX, Curve Finance, SushiSwap, 1inch, etc.
Diamond Hands
Someone who believes and holds a cryptocurrency or NFT regardless of the crypto or NFT market fluctuations.
Discord
Chat app heavily used by crypto and NFT communities for knowledge sharing and shilling.
DLT
Acronym for Distributed Ledger Technology. It’s a protocol that allows the secure functioning of a decentralized database, through cryptography. This technological infrastructure scraps the need for a central authority to keep in check manipulation or exploitation of the network.
Dog coin
It’s a memecoin based on the Japanese dog breed, Shiba Inu, first popularised by Dogecoin. Other notable coins are Shiba Inu or Floki Inu. These dog coins are frequently subjected to pump and dumps and are extremely volatile. The original dog coin DOGE was created as a joke in 2013. Elon Musk is one of Dogecoin's most famous supporters.
Doxxed/Doxed
When the identity of an NFT team member, dev or creator is public, known or verifiable. In the NFT market, when a NFT team is doxed it’s a usually sign of confidence and transparency for NFT collectors to ensure they will not be scammed for an anonymous creator.
Drop
The release of an NFT (single or collection) into the NFT market.
DYOR
Acronym for Do Your Own Research. A common expression used in the crypto or NFT community to disclaim responsibility for the financial/strategy advice someone is providing the community and to avoid being called out by others in theNFT or crypto community.
E
EIP-1559 EIP
Referring to Ethereum Improvement Proposal 1559, commonly known as the London Fork. It’s an upgrade to the Ethereum protocol code to improve the blockchain security and scalability. The major change consists in shifting from a proof-of-work consensus mechanism (PoW) to a low energy and lower gas fees proof-of-stake system (PoS).
ERC-1155
Stands for Ethereum Request for Comment-1155. A multi-token standard that can represent any number of fungible (ERC-20) and non-fungible tokens (ERC-721).
ERC-20
Ethereum Request for Comment-20 is a standard defining a fungible token like a cryptocurrency.
ERC-721
Ethereum Request for Comment-721 is a standard defining a non-fungible token (NFT).
ETH
Aka Ether, the currency symbol for the native cryptocurrency of the Ethereum blockchain.
ETH2.0
Also known as the London Fork or EIP-1559 EIP. It’s an upgrade to the Ethereum network to improve the network’s security and scalability. The most dramatic change is the shift from the proof-of-work consensus mechanism (PoW) to proof-of-stake system (PoS).
Ether
Or ETH, the native cryptocurrency of the Ethereum blockchain.
Ethereum
Network protocol that allows users to create and run smart contracts over a decentralized network.
F
FCFS
Acronym for First Come First Served. Commonly used strategy in a NFT collection drop when the demand surpasses the supply.
Few

Can space-based solar power solve Earth's energy problems?
Better technology and lower launch costs revive science-fiction tech.
Airbus engineers showed off sustainable energy's future in Munich last month. They captured sunlight with solar panels, turned it into microwaves, and beamed it into an airplane hangar, where it lighted a city model. The test delivered 2 kW across 36 meters, but it posed a serious question: Should we send enormous satellites to capture solar energy in space? In orbit, free of clouds and nighttime, they could create power 24/7 and send it to Earth.
Airbus engineer Jean-Dominique Coste calls it an engineering problem. “But it’s never been done at [large] scale.”
Proponents of space solar power say the demand for green energy, cheaper space access, and improved technology might change that. Once someone invests commercially, it will grow. Former NASA researcher John Mankins says it might be a trillion-dollar industry.
Myriad uncertainties remain, including whether beaming gigawatts of power to Earth can be done efficiently and without burning birds or people. Concept papers are being replaced with ground and space testing. The European Space Agency (ESA), which supported the Munich demo, will propose ground tests to member nations next month. The U.K. government offered £6 million to evaluate innovations this year. Chinese, Japanese, South Korean, and U.S. agencies are working. NASA policy analyst Nikolai Joseph, author of an upcoming assessment, thinks the conversation's tone has altered. What formerly appeared unattainable may now be a matter of "bringing it all together"
NASA studied space solar power during the mid-1970s fuel crunch. A projected space demonstration trip using 1970s technology would have cost $1 trillion. According to Mankins, the idea is taboo in the agency.
Space and solar power technology have evolved. Photovoltaic (PV) solar cell efficiency has increased 25% over the past decade, Jones claims. Telecoms use microwave transmitters and receivers. Robots designed to repair and refuel spacecraft might create solar panels.
Falling launch costs have boosted the idea. A solar power satellite large enough to replace a nuclear or coal plant would require hundreds of launches. ESA scientist Sanjay Vijendran: "It would require a massive construction complex in orbit."
SpaceX has made the idea more plausible. A SpaceX Falcon 9 rocket costs $2600 per kilogram, less than 5% of what the Space Shuttle did, and the company promised $10 per kilogram for its giant Starship, slated to launch this year. Jones: "It changes the equation." "Economics rules"
Mass production reduces space hardware costs. Satellites are one-offs made with pricey space-rated parts. Mars rover Perseverance cost $2 million per kilogram. SpaceX's Starlink satellites cost less than $1000 per kilogram. This strategy may work for massive space buildings consisting of many identical low-cost components, Mankins has long contended. Low-cost launches and "hypermodularity" make space solar power economical, he claims.
Better engineering can improve economics. Coste says Airbus's Munich trial was 5% efficient, comparing solar input to electricity production. When the Sun shines, ground-based solar arrays perform better. Studies show space solar might compete with existing energy sources on price if it reaches 20% efficiency.
Lighter parts reduce costs. "Sandwich panels" with PV cells on one side, electronics in the middle, and a microwave transmitter on the other could help. Thousands of them build a solar satellite without heavy wiring to move power. In 2020, a team from the U.S. Naval Research Laboratory (NRL) flew on the Air Force's X-37B space plane.
NRL project head Paul Jaffe said the satellite is still providing data. The panel converts solar power into microwaves at 8% efficiency, but not to Earth. The Air Force expects to test a beaming sandwich panel next year. MIT will launch its prototype panel with SpaceX in December.
As a satellite orbits, the PV side of sandwich panels sometimes faces away from the Sun since the microwave side must always face Earth. To maintain 24-hour power, a satellite needs mirrors to keep that side illuminated and focus light on the PV. In a 2012 NASA study by Mankins, a bowl-shaped device with thousands of thin-film mirrors focuses light onto the PV array.
International Electric Company's Ian Cash has a new strategy. His proposed satellite uses enormous, fixed mirrors to redirect light onto a PV and microwave array while the structure spins (see graphic, above). 1 billion minuscule perpendicular antennas act as a "phased array" to electronically guide the beam toward Earth, regardless of the satellite's orientation. This design, argues Cash, is "the most competitive economically"
If a space-based power plant ever flies, its power must be delivered securely and efficiently. Jaffe's team at NRL just beamed 1.6 kW over 1 km, and teams in Japan, China, and South Korea have comparable attempts. Transmitters and receivers lose half their input power. Vijendran says space solar beaming needs 75% efficiency, "preferably 90%."
Beaming gigawatts through the atmosphere demands testing. Most designs aim to produce a beam kilometers wide so every ship, plane, human, or bird that strays into it only receives a tiny—hopefully harmless—portion of the 2-gigawatt transmission. Receiving antennas are cheap to build but require a lot of land, adds Jones. You could grow crops under them or place them offshore.
Europe's public agencies currently prioritize space solar power. Jones: "There's a devotion you don't see in the U.S." ESA commissioned two solar cost/benefit studies last year. Vijendran claims it might match ground-based renewables' cost. Even at a higher price, equivalent to nuclear, its 24/7 availability would make it competitive.
ESA will urge member states in November to fund a technical assessment. If the news is good, the agency will plan for 2025. With €15 billion to €20 billion, ESA may launch a megawatt-scale demonstration facility by 2030 and a gigawatt-scale facility by 2040. "Moonshot"

I put my faith in a billionaire, and he destroyed my business.
How did his money blind me?
Like most fledgling entrepreneurs, I wanted a mentor. I met as many nearby folks with "entrepreneur" in their LinkedIn biographies for coffee.
These meetings taught me a lot, and I'd suggest them to any new creator. Attention! Meeting with many experienced entrepreneurs means getting contradictory advice. One entrepreneur will tell you to do X, then the next one you talk to may tell you to do Y, which are sometimes opposites. You'll have to chose which suggestion to take after the chats.
I experienced this. Same afternoon, I had two coffee meetings with experienced entrepreneurs. The first meeting was with a billionaire entrepreneur who took his company public.
I met him in a swanky hotel lobby and ordered a drink I didn't pay for. As a fledgling entrepreneur, money was scarce.
During the meeting, I demoed the software I'd built, he liked it, and we spent the hour discussing what features would make it a success. By the end of the meeting, he requested I include a killer feature we both agreed would attract buyers. The feature was complex and would require some time. The billionaire I was sipping coffee with in a beautiful hotel lobby insisted people would love it, and that got me enthusiastic.
The second meeting was with a young entrepreneur who had recently raised a small amount of investment and looked as eager to pitch me as I was to pitch him. I forgot his name. I mostly recall meeting him in a filthy coffee shop in a bad section of town and buying his pricey cappuccino. Water for me.
After his pitch, I demoed my app. When I was done, he barely noticed. He questioned my customer acquisition plan. Who was my client? What did they offer? What was my plan? Etc. No decent answers.
After our meeting, he insisted I spend more time learning my market and selling. He ignored my questions about features. Don't worry about features, he said. Customers will request features. First, find them.
Putting your faith in results over relevance
Problems plagued my afternoon. I met with two entrepreneurs who gave me differing advice about how to proceed, and I had to decide which to pursue. I couldn't decide.
Ultimately, I followed the advice of the billionaire.
Obviously.
Who wouldn’t? That was the guy who clearly knew more.
A few months later, I constructed the feature the billionaire said people would line up for.
The new feature was unpopular. I couldn't even get the billionaire to answer an email showing him what I'd done. He disappeared.
Within a few months, I shut down the company, wasting all the time and effort I'd invested into constructing the killer feature the billionaire said I required.
Would follow the struggling entrepreneur's advice have saved my company? It would have saved me time in retrospect. Potential consumers would have told me they didn't want what I was producing, and I could have shut down the company sooner or built something they did want. Both outcomes would have been better.
Now I know, but not then. I favored achievement above relevance.
Success vs. relevance
The millionaire gave me advice on building a large, successful public firm. A successful public firm is different from a startup. Priorities change in the last phase of business building, which few entrepreneurs reach. He gave wonderful advice to founders trying to double their stock values in two years, but it wasn't beneficial for me.
The other failing entrepreneur had relevant, recent experience. He'd recently been in my shoes. We still had lots of problems. He may not have achieved huge success, but he had valuable advice on how to pass the closest hurdle.
The money blinded me at the moment. Not alone So much of company success is defined by money valuations, fundraising, exits, etc., so entrepreneurs easily fall into this trap. Money chatter obscures the value of knowledge.
Don't base startup advice on a person's income. Focus on what and when the person has learned. Relevance to you and your goals is more important than a person's accomplishments when considering advice.
