It may sound like sci-fi vision .but some space agency is dead serious:2030 it wants to collect solar power in space and zap it down to earth, using laser beams or microwaves.
They has just picked a group of firm and a team of researchers tasked with turning the ambitious, multi-billion-dollar dream of unlimited clean energy into reality in coming decades.They has long has long been a leader in solar and renewable energies and this year set ambitious green-house gas reduction.But their boldest plan to date in the space solar power systems (ssps), in which arrays of photo-voltaic dishes several square kilo-metres, in size would hover in geostionary orbit outside earth's atmosphere." since solar power is a clean and inexhaustible energy source, we believe this system will help solve the problem of energy shortage and global warming," researchers at Mitsubishi Heavy Industries, one of the project participants.
The solar cells would capture the solar energy, which is at least five times stronger in space than on Earth, and beam it down to the ground through clusters of lasers or microwaves. These would be collected by gigantic parabolic antennae, likely to be located in restricted areas at sea or on dam reservoirs,
The researchers are targeting a one gigawatt systems, equivalent to a medium-sizes atomic power plant, that would produce electricity , six time cheaper than its current cost in the World.
the next step, expected around 2020, would be launch and test large flexible photovoltaic structure with 10 megawatt power capacity, to be followed by a 250 megawatt prototype.
This would help evaluate the project's financial viability, say officials.The final aim is to produce electricity cheap enough to compete with other alternative energy sources.
