Jitendra, you just did the forbidden "SilentRage is wrong" type of remark. I did not lie to you. Quote:

"Once the lightcraft is spinning at an optimal speed, the laser is turned on, blasting the lightcraft into the air. The 10-kilowatt laser pulses at a rate of 25-28 times per second. By pulsing, the laser continues to push the craft upward. The light beam is focused by the parabolic mirror on the bottom of the lightcraft, which heats the air to between 18,000 and 54,000 degrees Fahrenheit (9,982 and 29,982 degrees Celsius) -- that's several times hotter than the surface of the sun. When you heat air to these high temperatures, it is converted to a plasma state -- this plasma then explodes to propel the craft upward."

But anyway people, that is far from the coolest thing that site discusses. It also describes how matter/antimatter engines will work (just like in the old Star Trek) and how teleportation will work (again, just like in Star Trek) and how DNA computers will work. It's not just fantasy stuff either, they've actually done some of everything above.

All kinds of neat stuff.
