Space Solar Energy Initiative
For the past several years the Space Island Group (SIG), working with America's top aerospace companies, has aggressively pursued the development of a commercially profitable, industrial infrastructure in orbit. Our infrastructure will consist of 3 interconnected elements.
The first is Space Solar Power (SSP) satellites that over the next 2 decades, will deliver trillions of kilowatt-hours of environmentally clean electric energy to virtually any location on Earth. The second is mass-produced, economical launch vehicles able to carry SSP satellite components to orbit, but the third element is the one that makes SIG's approach absolutely unique in the aerospace community. SIG will leave the cavernous airtight fuel tanks and "cargo pods" from their launchers in orbit when empty, then convert their interiors into very large, habitable facilities which will be leased by a wide range of commercial tenants.
These lease revenues will recover the entire cost of each launch within 1 year, meaning that the solar satellite components can be carried to orbit for "free". Since the cost of launching SSP components is 20 times higher than the cost of manufacturing those components, this revolutionary approach will allow SSP satellites to profitably generate and deliver their clean energy directly to thousands of remote locations or to major cities at prices below the cost of generating and transporting electrical energy on Earth.
The space hardware needed for all 3 of these elements has been in production by aerospace companies for 3 decades, and the concept of building a space station inside a converted rocket fuel tank was the basis of the Skylab space station that NASA built in the early 1970's. By working closely with NASA, SIG has identified several hundred companies eager to lease these orbiting facilities for research, manufacturing and even tourism.
SSP satellites are basically sheets of solar cells up to a mile across that will orbit 22,000 miles above the Earth. Their components convert sunlight into electricity, then use very weak microwave beams to transmit that energy down to simple receiving antennas anywhere on Earth. This environmentally clean, safe transmission continues 24 hours a day with no nighttime or storm-related interruptions, which is an enormous advantage over intermittent ground-based energy alternatives like windmills or roof top solar, The receiving antennas convert the beams back into electricity and feed it into standard power grids, or directly to factories or households nearby.
NASA has refined SSP designs for decades. All of their components are in production today for military and communications satellites. The one component that may not be familiar to the public is microwave transmitters that can "beam" electrical energy from point to point. The video in this section documents a demonstration of this technology that NASA and the Raytheon Corporation conducted in 1975. Since then simpler, far more efficient and far less expensive solid state hardware has been developed to accomplish this same task.
