No matter how good the solar panels on your roof are, they aren’t good
enough to collect energy at night. But researchers at the Japan
Aerospace Exploration Agency (JAXA) have hatched a plan to harvest the
sun’s energy nearly 24 hours a day. The idea is to launch solar-energy
collectors into geosynchronous orbit. The special satellites would beam
microwave energy down to an array of tiny rectifying antennas that would
convert microwaves into DC electricity. Sound far-fetched? The JAXA
team says that technical advances such as improvements in wireless power
transmission, along with heightened public concern about the burning of
fossil fuels, are providing the impetus to make their seemingly sci-fi
vision a reality in the not-too-distant future. https://mail.google.com/mail/?shva=1#all/145d7790fe003245 |
