Controversy Flares Over Space-Based Solar Power Plans

"Solaren would then need to launch a solar panel array capable
of generating 400 megawatts. The total launch weight of all the
equipment would be the equivalent of about 400 metric tons,
or 20 shuttle-sized launches, according to Hoffert.

But Solaren says that it would just require four or five heavy-lift
rocket launches capable of carrying 25 metric tons, or about
one fourth of Hoffert's weight estimate. The company is relying
on developing more efficient photovoltaic technology for the
solar panels, as well as mirrors that help focus sunlight.

Solaren has not provided details on just how its technology
works, citing intellectual property concerns. But it expects that
its space solar power can convert to RF energy with greater
than 80 percent efficiency, and expects similar conversion
efficiency for converting the RF energy back to DC
electricity on the ground in California. The company also
anticipates minimal transmission losses from the space
to the ground."

The 'inevitable' is steadily becoming possible...imho.
