Awesome! I once (more than 10 years ago, wow) had an idea to attach solar heater to vacuum/gas CVD system to make graphene, but my PI at the time said it’s dumb idea, sure it will work, no novelty there. Now I have no idea why I would want to make graphene, and pass all the free lenses in second hand shops. Now if making the forge is feasible (I had doubts), I’m totally doing it too, in Finland!
