Per Jack Rickard's latest podcast:
Tesla's "transparent metal glass" is "transparent aluminum" (ALON, Alumium Oxynitride). Actually a ceramic, sintered at very high temperatures and pressures. Strength: 350MPa on its own, and can get up to 700MPa by polishing the surface. Was 80% optical clarity, but new techniques are up to 98% optical clarity. About the same hardness as sapphire. Used in some military glass applications.
Harder glasses tend to have more perfect, highly polished surfaces, and a side effect of this is that it's a natural Rain-X.
Re: windshield wipers: he thinks that if it really is something like polished ALON, water, dust, mud, etc won't even stick, so you might not even need them. "Permanent Rain-X. Probably better than Rain-X."

You described the laser trapped within the glass by internal reflection. Now you're talking about transferring high amounts of energy outside of the glass. You can't have it both ways. Not to mention the absurd power levels needed to instantly vaporize large volumes of water, the damage incurred to the glass by the heat and reactivity of "vaporized dirt", the difficulties in aiming laserbeams through a thin panel to precisely strike these spots at high angles of incidence, etc. Surely you're joking.lilly said:laser doesn't have to touch the dirt nor water to vaporize it. The heat of the laser on the spot of water or dirt on the glass will vaporize it.Nubo said:How does the laser manage to vaporize water (much less, dirt!) if it is trapped by internal reflection inside the "glass"?
