Space-based solar power (SBSP) is the concept[d 1] of collecting solar power in space (using an "SPS", that is, a "solar-power satellite" or a "satellite power system") for use on Earth. It has been in research since the early 1970s.[1][2]
SBSP would differ from current[d 2] solar collection methods[d 3] in that the means used to collect energy would reside[d 4] on an orbiting satellite instead[d 5] of on Earth's surface. Some projected benefits[d 6] of such[d 7] a system are a higher collection rate[d 8] and a longer collection period due[d 9] to the lack[d 10] of a diffusing[d 11] atmosphere and night time in space.
Part of the solar energy (55–60%) is lost on its way through[d 12] the atmosphere by the effects of reflection[d 13] and absorption[d 14]. Space-based solar power systems convert[d 15] sunlight to microwaves outside the atmosphere, avoiding[d 16] these losses[d 17], and the downtime[d 18] (and cosine losses[d 19], for fixed[d 20] flat-plate[d 21] collectors) due to the Earth's rotation[d 22].
Besides[d 23] the cost of implementing[d 24] such[d 25] a system, SBSP also introduces several new hurdles[d 26], primarily[d 27] the problem of transmitting[d 28] energy from orbit to Earth's surface for use. Since[d 29]wires extending[d 30] from Earth's surface to an orbiting satellite are neither[d 31] practical[d 32] nor[d 33] feasible[d 34] with current technology, SBSP designs generally include the use of some manner[d 35] of wireless power transmission[d 36]. The collecting satellite would convert[d 37] solar energy into electrical energy on board, powering[d 38] a microwave transmitter or laser emitter[d 39], and focus[d 40] its beam[d 41] toward[d 42] a collector (rectenna[d 43]) on Earth's surface. Radiation[d 44] and micrometeoroid[d 45] damage could also become concerns for SBSP.
