The melting temperature of most types of glass is around 550C and the specific heat is 0.7J/gC. The latent heat of glass is 10kJ/mol, and on average, it has 60g/mol, so we have 166J/g. 1.5*10^6g*530*0.7J + 166*1.5*10^6J per day, that around 880MJ/day. If the exposition work lasted 8 hours a day, we have ~20KW.
Rossi worked within a 9*2.5*2.5m^3 ~56m^3. If the efficiency is 95%, and the hot air is blow towards the inside the container instead of outside, he had to deal with 50KW. 2016-05-17 14:25 GMT-03:00 Jed Rothwell <jedrothw...@gmail.com>: > > > How much power did it use? > > >
