Don’t cross Eric Jacqmain or he’ll vaporize you in a New York minute. The Indiana based teenager is the genius brain behind the R5800 solar “death ray”. Made up of 5,800 tiny mirror tiles covering an ordinary fiberglass satellite dish, this killer weapon is just 42 inches and generates enough power to melt steel, vaporize aluminum, boil concrete, turn dirt into lava and obliterate any organic material in an instant. The death ray is so good at vaporizing objects; it met its own demise in a shed fire it started. And now the budding inventor is back to the drawing board working on an even more powerful alternative. Perhaps whoever coined the term “weapons of mass destruction” was thinking about this kid.

steel melting point = 84 kJ/kg
Aluminium boiling point = 9210 kJ/kg
you can use only 42% of that power for steel and 20% for aluminium (opacity). sooo... it should work but only on very small area and for very small/thin pieces of metal
He justs concentrating solarpower in a point with mirror.
