Other than our sun we have no fusion reactors. So He3 remains a fantasy commodity.

The Planetary Resources folks correctly say water is the most valuable space commodity. Propellant high on the slopes of earth's gravity well breaks the exponent in Tsiolkovsky's rocket equation. And the rocket equation is what keeps space transportation expensive.

And there seems to be abundant water in the cold traps at the lunar poles.

Polar water comes from comet, not magma

The absence of water in magma does nothing to disprove the presence of polar ice.

Polar ice is thought to be frozen out vapors from comet impacts accumulated over the eons.

The article isn't merely stupid. It's blazingly stupid.
