I was just watching a documentary, and guess what: they used a 10,000 Watt (10 kW) 808nm IR laser to test the concept of space elevators! :drool:

The laser is introduced at approximately 28:50, and is fired and demonstrated at 30:09.

Here is the documentary:

That is one powerful laser!
 





Imagine the power needed to push real things like people and such....You would need a whole hell of a lot of power to achieve such thrust i imagine(there is my little disclaimer, that way if someone calls me out I can say "well I just imagined" lol)

1 Exawatt? :)
 
If there is a 10KW Laser being fired to supply power
to the lifting platform.... Why is no one in the room
wearing eye protection....:thinking:

They do have eye protection as you can see @ 30:00


I wonder how can a laser propel an object instead of burning through it.
 
You are correct...
At 30:17 it looked like they were not wearing any goggles..:yabbem:

"max output" doesn't mean much. In practice, it can be 2-3 times the rated output. But these are students that probably made their own sign.

Looks to me like they pointed a beam at a solar cell or something of that nature and used the voltage generated to drive a motor. You don't need anywhere near 10kW to propel something that small.
 
Well that was pretty disappointing video, at least from laser perspective. They showed nothing.

This shows different kind laser propulsion .. but it actually does show it.
