“According to the International Energy Agency (IEA), the worldwide demand for primary
energy increases by 55 per cent [sic] between 2005 and 2030 – 1.8 per cent hike per year on
average.”
(Dr. Rajagopalan, Billion Year Plan)
So where will this energy come from?
Oil Alternatives: Space-Based
PowerThe energy solution that is literally out of this world.
Just as space seems to be endless, so is the power that it has to offer. Providing energy 24 hours a day, 7 days a week, nations around the globe have found that space is a promising source of alternative
energy. With the necessary money and technology, a future of Solar power and Solar Wind from space could very well be the answer to
Earth’s seemingly unsolvable energy crisis.

“A single kilometer-wide band of geosynchronous Earth orbit experiences
enough solar flux in one year to nearly equal the amount of energy contained within all
known recoverable conventional oil reserves on Earth today.”
(Berger, Space News)
What is Space-Based Solar Power?
Space-Based Solar Power (SBSP): “A proposed system for the collection of solar power in space, for use on Earth.” (Wikipedia)
- Time to Earth: ~8 minutes- 24 Hour energy (no rotation or weather)- 144% greater than that collected on surface (5 times stronger)- Equipment not as easily damaged- 90% light penetration

According to Wikipedia, there are 3 basic steps in the use of Solar power
form space:
1. “A means of collecting solar power in space” ex: solar cells, panels
2. “A means of transmitting power to earth” ex: infrared laser, microwaves
3. “A means of receiving power on earth.” ex: laser bases, microwave antennas (rectifying antennas or rectennas)

Japanese Solar Satellite Project
Price: Two Trillion Yen ($21 Billion)Planning: Japanese Government’s Institute of Energy Economics, Japanese
Trade Ministry, Japan Aerospace Exploration Agency (JAXA), Excalibur, Japanese Space Development and Utilization Ministry, Kyoto University
Funding: 16 companies (Mitsubishi Heavy Industries, Mitsubishi Electric Corp., Sharp Corp., Tokyo-Based IHI Corp.)
Where: Geo-Synchronous orbit (~35,000 km above equator)Potential Power: ~300,000 homes
(Business Green, Physorg)
“A satellite with a 1,000-meter (3,280-foot) cable and a sail 8,400 kilometers (5,220 miles)
across . . . would generate one billion billion gigawatts of power. That’s Approximately 100 billion times the power Earth currently uses.”
(Bland, Discovery News)
What is Space-Based Solar Wind?Solar Wind: “A stream of energized, charged particles, primarily electrons
and protons, flowing outward from the Sun, through the solar system at speeds as high as 900 km/s and at a temperature of 1 million degrees (Celsius).” (Northwestern University)

From Freeman Dyson and Brooks HarropPrice: Less than that of a solar power project
Planning: Designed by scientists from Washington State University, NASA, DOE, NSSO.
Potential Funding: Government (DOE) grants/loans, Sharp (as in Japan), General Electric, and other smaller/private companies such as Pacific Gas &
Electric. Where: Higher latitude Sun-Synchronous orbit (with the Earth)
Potential Power: Depending on size,100 billion times more than Earth’s current usage.

Cons and Challenges FacedDevelopmental/Operational Challenges:- Cost (expensive, far from commercial usage) •reusable spacecraft to transport materials •moon launches may prove cheaper •currently, wind is cheaper than solar- Energy Transmission (Beam, wave, wire) •Microwave or laser for solar/ infrared laser for wind •Microwave beams could have a maximum 23 MW/cm², but U.S. Occupational Safety and Health Act (OSHA) limits the amount to 10 MW/cm²- Technological Needs (Prototypes and research) •better robotics equipment, solar cell efficiency, etc. - Vulnerable to Other Threats/Dangers •solar storms, micrometeoroid impacts, rapid radiation/meltdowns- Location •distance causes construction difficulties
Arguments and Concerns: Debate
- Effects on the Atmosphere (exhaust released)
- Effects on Wildlife and Environment
- Human Exposure (Coating aircraft, preventing contact with beams)
