Solar energy.... Japan launches study on space...

["Bjorn Cedervall" <bcradsafers@HOTMAIL.COM>]

The text below dropped in via Sandy - can anyone confirm regarding the 

1-kilowatt capacity/satellite. It doesn't sound much (?) - 1 000 to 10 000 

MWe would have seemed more reasonable. I am also interested in this topic 

since a success could mean that we will put the Earth into focus of a 

"magnifying glass" (numerous satellites). Animals and other organisms may 

vanish in "both ends" (not enough with cold for high altitude or (ant)arctic 

animals&plants, overheating of those which live in hot areas today). OK - 

this solar radiation idea is perhaps too off-topic so please send the 

"non-radiation" comments to me directly - rather than to the group.

Japan launches study on space solar power as energy source



TOKYO, July 3 (Kyodo) - The Ministry of Economy, Trade and Industry

(METI) said Tuesday it has launched a two-year feasibility study on

developing solar power in space as an alternative source of energy.



The ministry aims to realize by 2040 a system of power generation

using satellites that can send electricity to Earth by microwaves.



Each satellite would have a 1-kilowatt capacity, equivalent to power

generation by a nuclear plant, a ministry official said.



The envisaged system will also be 10 times more efficient than solar

power systems on Earth because of its indifference to sunlight and

will emit no heat-trapping carbon dioxide, METI said.
