Solar Power Station in Space

Former chairman of Bharat Dynamic Ltd Mr Gopalaswamy, who made
pioneering work in the field solar energ.Heis widely regarded as a
"missionary" for solar energy. "The era of conventional fuels is
ending. The sun's intensity in space is nearly twice what we feel here
on the Earth's surface. On Earth, there is sunlight fit for power
generation for six to eight hours a day. In space, it's 24 hours. We
need to have our own solar power station in orbit," he said.
"Even if one per cent of our nation's land area is utilised for solar
energy, we could have nearly 1,000 giga watts of electric power.
Consider this as the projected demand in 2030 is 400 GW and the
current consumption is 120 GW," he said to drive home the need to have
solar power station in space. He also gave a possible collaboration
scenario. For instance India, Brazil and South Africa have very good
relations. They could collaborate on the technologies, infrastructure
and expertise.
The Scientific community and industry will meet this challenge,The
focus on the two-day conference on hypersonic technology for trans-
atmospheric air and space transportation, which will be inaugurated by
President Dr APJ Abdul Kalam on Friday.
Mr Saraswath said RLVs are needed to make this mission cost effective.
The hypersonic technology demonstrator vehicle (HTDV) is basically a
fast transport vehicle into space. Defence organisation is making the
HTDV, while Indian space organisation is making the RLV.
Interestingly, the scram jets needed for these vehicles to work are
currently being tested in Hyderabad.
