Darn, why didn't he put the hand in the beam, would be far more impressive than melting steel.

#4 Way to go wrecking my head for the rest of the day :P

I only have one problem with this its, a Parabolic mirror it does produce a "beam" but its only effective at its focal point. What there doing here is stunning to watch , but only laser light to me is a true beam and read why here (sry i know wiki..)

Enough show and tell. Boil some water, make some steam, power a turbine, turn a generator and make some electricity!

Pretty amazing build he had there. What exactly does that device do and is it powered by anything(beside the sun)?

I wonder why we have nothing like that at home to heat up our water, or grill the meat.

#4 short answer: it would instantly melt the mirror.

Long answer: It would melt the mirror because a mirror consists of a reflecting metal layer that *behind a sheet of glass*.... so the light beam would pass through the glass (heating it up), hopefully be reflected by the metal layer, then pass back through the glass once more. Clearly, the glass would absorb some of that energy and as it does so, the metal layer will become less reflective. These two effects quickly reinforce each other, so the melting would start practically right away.

The mirror will melt faster than the metal bolt we saw - because the metal bolt has more matter into which the heat can be absorbed.

Good thing that guy didn't put his hand in the beam... glad he was only kidding.

#15 we do have that. Modern homes are often equipped with solar-powered water heating systems. I get free hot water every day the sun shines! (I still need to pay for the water though :) )
