Laser Pumped Flying Saucer Spacecraft

The "Lightcraft" is a laser-propelled spacecraft concept that could ultimately run on other beamed energies, such as microwave.

brilliant

[coderanger]

The main advantage of beamed-energy propulsion is that the energy source (in this case whatever is powering the laser/maser) doesn't have to move. Putting it on the craft itself means you need to life the fuel as well as the ship and its contents. Not having to lift your own fuel allows for the hugely smaller spacecraft.

Much success on this!

State which unit of room temperature and I might actually consider it seeing I use Celcius (like normal people) it wouldnt take much of a genius to nulify your statement. You state facts but provide none.

what's wrong with your caps lock button?

[rbolo29]

This crappy and weak form of propulsion would never work in the real world.

[UltraConfix]

I think you left your caps lock on

THEY FOUND THEIR SATELITTES FAILED SOMEWHERE OVER THE USA FOR SOME REASON.SOOO THEY PUT LASER DETECTORS ON THE NEW SATELITTES. IT WENT TO I THINK THE UNATIONS. THERE WAS NO LAW GOVERNING SHOOTING LASERS AT SATELITTES. SOOO UN MADE ONE.

SO THERE WERE VERY GOOD TARGETING SYSTEMS IN THE 80 S FOR SATELITTE DISABLEMENT.

LASER FROM EARTH IS ANOTHER STORY STILL WASTFULL IF U DONT GO SOLAR OR ALTERNATIVE ELECTRIC CAUSE OF LASER EFFICENCY AGAIN. IT WOULD TAKE MORE THAN ONE LASER DUE TO THE DISTANCE COVERED DURING ACCELERATION,IT WOULD NEED A HAND OFF TO ATLEAST ONE MORE LASER TO CONTINUE ACCELERATION. TAKES ABOUT TEN MIN TO REACH ORBITAL VELOCITY IN A NORMAL ROCKET. THE PROBLEM OF AIMING THE LASER IS SOLVED THOUGH IN CASE UR INTERESTED. BACK IN THE 80S

THE RUSSIANS WERE LOOKING AT THINGS WITH SATELITTES AND CONT.

[mistake mistak]

THE PROBLEMS WITH LASERS IS THE EFFICENCY. LIKE LESS THAT 10%. SO IF U HAD TO FUEL FROM EARTH SOMTHING LIKE 9 TIMES THE FUEL. SO IF FUELED BY SOLAR THE ELECTRIC STORAGE VOLUME WOULD BE.SOMWHERE AROUND TEN TIMES THE SIZE OF THE NORMAL ROCKET. TO SOLAR CHARGE THIS WOULD IM ESTIMATING MONTHS TO YRS. IF IT WAS NUCLEAR ELECTRIC ITD CHARGE FASTER ONLY TO RUN OUT OF FUEL AFTER A FEW LAUNCHES. IM REFERENCING THE LAST MODEL WITH THE SATELITTE.

What facts? We already possess an anti gravity drive? You provided no sources for this information...Why? If I were to hazard a guess, it's because not one shred of evidence whatsoever exists to support such a statement. Go ahead and show me all the ufo pics/vids you want - I've seen them all and not denying they exist. But they are just that: unidentified. Speculating is fun and who doesn't like a good conspiracy theory, but I'll wait for some solid physical proof before stating any "facts".

[steve shepherd]

why do they bother wasting all this money & all this scientific know how when we already possess ANTI GRAVITY DRIVE. all this time,money thrown away, solely to try and fool the public who already KNOW BETTER, For gods sake stop wasting all that money on NASA, solely to fool the the MORONS of this WORLD. Use the the Money to repair the infrastructure, which would create 100's of thousands of JOBS FOR AMERICANS! I dare anyone with an I.Q. above room temperature to argue with my FACTS!
