- Last week college professor Andrew Pakhomov was found guilty of murdering his wife, Yelena Zakin. She was strangled and her naked body was found in the Tennessee River in June 2006. But Pakhomov was not some dusty academic. He worked at the cutting edge of military technology, working on laser-powered propulsion for space launches.
- Pakhomov is President of the American Institute of Beamed Energy Propulsion, which offers this layman’s description of the technology on their website: “Rockets have to carry onboard their fuel (hydrogen), burning agent (oxygen) and everything else that is needed to burn hydrogen and maintain motion in the desired direction (tanks, cryogenics, combustion chamber, fuel lines etc.). This is a heavy burden, and it brings a big downside: the price of cargo gets enormously high … If we could separately provide the propulsive energy for a rocket, we would be rewarded with a gigantic increase in efficiency!”
- In Beamed Energy Propulsion, a laser or other high-energy beam is focused on solid fuel, causing it to expand rapidly. Because the laser and power supply are on the ground, the launching process is far more efficient. Pakhomov quotes independent analysts who have shown that laser propulsion will be around a hundred times cheaper than conventional propulsion for launches to low Earth orbit, bringing the price down from $10,000 a pound to $100.
