Building Space Based Solar Panels

Space based solar power attracted considerable attention in the 1970s as the necessary individual technical components in essence photovoltaic cells satellite technology and wireless power.

Building space based solar panels.

Science fiction writer isaac asimov is credited with bringing the idea of space based solar power projects to prominence in 1941. Apart from providing around the clock power on demand beamed from space the new solar cells panels and production processes being developed through the program could revolutionize space based. Power to run the sensors active heating cooling and telemetry. Space stations and satellites already use solar panel arrays for.

Among their conclusions was that launch costs would need to come down to 100 200 per kg to make space based solar power economically competitive. Power for spacecraft propulsion electric propulsion sometimes called solar electric propulsion. It is hard to imagine accomplishing a factor of 100 reduction in launch costs. Mankins and others estimate the total cost for developing building launching and assembling all the components of a space based solar power plant is on the order of 4 to 5 billion a fraction.

These panels convert solar power into either a microwave or a laser and beam uninterrupted power down to earth. China is planning to build the world s first solar power station in space to provide inexhaustible clean energy according to a story in science and technology daily the official newspaper of. In fact this technology was mentioned way back in 1941 in the science fiction story reason written by isaac asimov. On earth power receiving stations collect the beam and add it to the electric grid.

Solar panels on spacecraft supply power for two main uses. In 1999 nasa initiated a 22 million study investigating the feasibility of space based solar power. The two most commonly discussed designs for sbsp are a large deeper space microwave transmitting satellite and a smaller nearer laser transmitting.
