Is making photon Engine possible ? :A different thought to power space craft!
Now a days Scientists are working on photon engine. They are trying to power engine from light. Thought is looks great but there is practical engineering problems with it.
Ya it is true that photons have momentum (But very small)...Because what is a photon, It is just an light energy particle. Which carry light energy. ok
so if photon have momentum then what is the practical problem in making Photon engine.
The problem is, photon have very very small momentum. So you need a gigantic lager system to propel a small engine and a big lager system is directed toward chemical reactions.
so it is impossible to make a photon engine but this idea can be useful in different way...
Think for a moment if we can reduce the mass of rocket then it is very easy and low cost method to go in space. 90% mass of rocket is just because of its fuel. Means a rocket needs power to lift his fuel also. We can eliminate this 90% fuel mass if we can supply energy from outer side to rocket. And the only solution is LASER beam.
We need to establish a Laser system on Earth to focus on spacecraft and spacecraft will be full of water. this water will be heated by laser and the water vapor will provide thrust to push the craft.
this idea can reduce the cost as well as efficiency of space shuttles.
