Beamed power transmission from solar power satellites pdf

On earth, solar power is greatly reduced by night, cloud cover, atmosphere and seasonality. Some 30 percent of all incoming solar radiation never makes it to ground level. In space the sun is always shining, the tilt of the Earth doesn't prevent the collection of power and there's no atmosphere to Space-based solar power (SSP) generation is being touted as a solution to our ever-increasing energy consumption and dependence on fossil fuels. Satellites in Earth's orbit can capture solar energy through photovoltaic cells and transmit that power to ground based stations. Solar cells in orbit are Space Based Solar Power satellites use solar arrays to generate clean, green, and renewable electricity in space and transmit it to earth via microwave, radiowave or laser beams to corresponding receivers (ground stations). These traditionally are large structures orbiting around earth at the Power satellites are an idea that has been around since the late 1960s but not developed commercially because we don't know how to build an inexpensive space transport system. That may have changed recently, at least in theory. We have known for decades that solar power satellites 1968s idea for Solar Power Satellites proposed by Peter Glaser. Would use microwaves to transmit power to Earth from Solar Powered Satellites. If microwave beams carrying power could be beamed uniformly over the earth they could power cell phones. Biggest problem is that the antenna A solar power satellite, or SPS or Powersat, as originally proposed would be a satellite built in high Earth orbit that uses microwave power transmission to beam solar power to a very large antenna on Earth. Advantages of placing the solar collectors in space include the unobstructed view of the Sun Outline Background Solar Power Satellite Microwave Power Transmission Current Designs Conclusion. Microwave vs. Laser Transmission Microwave More developed High efficiency up to 85% Beams is far below the lethal levels of concentration even for a prolonged exposure Cause For SPS Wireless power transmission is essential. WPT contains microwave beam, which Solar Power Satellites (SPS) converts solar energy in to micro waves and sends that microwaves in to a Solar Power Satellites is known by a variety of other names such as Satellite Power System, Space With space-based solar power One of NASA's most extensive studies ever devised, the Satellite Power System Concept Another fundamental study NASA funded to re-evaluate and understand the feasibility of SBSP was the Space Solar Power Exploratory Research and Technology (PDF) program. 23.
