greenpowerscience.com This is our big sub -level 2 lens. I have one that is even stronger. The saw blade is solid steel. Total time through the blade was 3 minutes. All other melts were realtime.

The plastic plates weren’t very green. Just sayin’.
Great idea; thanks!
I would totally have sex on that lens. very nice!
Do you think you could shape a rock in to a block or into a perfect ball using the death ray?
If so maybe that is how the Mayans (sp) in South America shaped there blocks that fit together so well. not with plastic but with glass
I think they use direct sun light to weld in space.
Ah it can melt iron.
If you connect some fiber optics could you harness and focus more accurately?
tray sand!
The problem it to manage the welding process.
that was awesome
You may have already touched on this so my apologies if you have, but could you power a steam generator for producing “free” electricity during the day time and charging a bank of batteries for night time use?
seriously?
How about your death ray on a watermelon? if aimed at the center inside, would it boil and eventually explode? Water, how fast can one make a pot boil? Anyone with a variable parabolic reflector would have the equivalent of a laser gun. Great video!
cut through stone?
Some thinner metals you can.
Hi,
Our web site has some links:-)
geez…can you weld with that thing??
Lol.. you could burn zombies all day with that thing.. =P
Can one use this to weld or do forging?
I’m 13 and i want to make one! lolol how?
If you could track it slow enough you could probably weld with this.
(Love the disclaimer at the end!)
If i was to use a laser how much power would need ? over 10 watt ?
You would think we could produce massive amounts of electricity from its incredible heat .even if the sun doesn’t shine all the time.
What the rainbow?
hehehehe XD much more to my liking!!!!
Be careful Son.
