The idea is to focus rays into a cavity which singles out each ray. Then a device collects that ray of light and magnifies it to such an extent (super hot) and then ignites a liquid fuel, thereby creating propulsion in space...not on earth!
You can boil water with one magnifying glass! You can boil water faster with multiple magnifying glasses. These magnifying glasses are small handheld. If you were to use small optical magnifying glasses (one on top of the other) would it not do exactly the same thing when using multiples to boil...
Right it is mostly plasma, but the UV Rays are not! Correct?
If you put take the sun rays as you do when you use a magnifying glass to burn something, then pass it through some reflecting mirror's and focus the light on the center of a magnifying disc; would it not make the stream of light stronger?
If the sun is producing plasma on a large scale on a regular basis, isn't it then true on a smaller scale that we could use the UV Rays of the sun to produce plasma by smashing two magnified rays and liquid hydrogen together in a high speed chamber? The result would be hot plasma that could be...
