Extra-Solar Power


Energy articles are plentiful lately.

We've looked at wind, solar, wave, nuclear, ethanol, bio-diesel, coal, oil, and natural gas.

We've looked at energy from all different angles such as economic markets, investment strategies, food, transportation, efficiency, etc etc.

CNN reports on the race for solar power captured in space and beamed to earth.

From the Sun's perspective, Earth is a barely visible speck, if that.

From that perspective, the potential for solar power in space is unlimited.

CNN: How to harvest solar power? Beam it down from space!
...another solution for India's chronic electricity shortage (is) one that does not involve power plants on the ground but instead massive sun-gathering satellites in geosynchronous orbits 22,000 miles in the sky.

The satellites would electromagnetically beam gigawatts of solar energy back to ground-based receivers, where it would then be converted to electricity and transferred to power grids. And because in high Earth orbit, satellites are unaffected by the earth's shadow virtually 365 days a year, the floating power plants could provide round-the-clock clean, renewable electricity.
