The leg is good, walking with a limp still. I took the pictures last week but they have on a 1 post per day so I couldn't post them from my phone. I know physics plays a big role but I am a big fan of new technology. Remer when Tesla first met Edison and told him that he had an Idea to create a ac current motor, Edison said it will never work and that most cities were already wired with dc, so what happened the crazy guy with no engineering experience demostrated that Edison was wrong. I believe Robert is capable of bringing a heater that can match or even beat whatever is out there.
