Why Don’t We Have Laser Guns?
March 8, 2012 in Daily Bulletin
Laser guns have long been a staple of science-fiction. Why then don’t we have any yet? Jeff Hecht answered the question:
- Lasers aren’t energy efficient. They work by converting other forms of energy into light, but a lot of energy is lost as heat in the process.
- The only way for a laser to kill is through heat. But the human body is mostly made up of water, and it requires a lot of energy to heat water up. Thus a laser gun would require a prohibitive amount of power.
- The one thing lasers can do well is burn out a person’s retinas. However staring at the sun has the same effect, and anyway the Geneva conventions don’t allow for such tactics.
