Some of Us Need to Get Off This Planet

There are too many ways for the existence of our entire species to be threatened without good recourse as long as we’re all on a single planet. We need to diversify our locations and provide alternative responses for survival. An asteroid strike, a gamma ray bombardment, a super volcano, an accident from bio-genetic tinkering, a […]

The Moon as a Fuel Depot

There are good reasons to mine the Moon. Ice will supply water and oxygen for life, and hydrogen and oxygen for fuel. Aluminum and other metals can be extracted and formed into basic building block materials for construction. But both the ice and the building materials will be mostly thrown out into space for use […]

Thermopower Waves from Nanotubes

Heat produced by burning fuel in a carbon nanotube “wick” can force a wave of electrons down the tube, producing electric current. An engineering lab at MIT has made new progress on this technique. Thermopower Waves (from “Daily Planet”) [youtube.com] A clip from an episode of “Daily Planet” on Discovery Channel Canada featuring the research […]

Refueling in Space Means Staying There

Our future lies in space, not pinned down on the surface of a planet at the bottom of a gravity well. Once we have managed to climb out of that dark hole, we will have little reason to go back down into it. Most of the fuel required for space travel is burned up in […]

Water on the Moon and Mars

It has long been known that water exists in comets, asteroids, on Mars and on the Moon, but the key question has always been, “how much is there?” Shadows in craters at the Moon’s poles have been suspected to hold some ice, but there was little hope of finding enough moisture across the rest of […]
