He sure the f**k did! Evidently you don't know anyone that brought engineers to the demonstrations and examined the devices. NO HOAX - sorry ;) You have not investigated deeply, my friend. Since Mr. Musk is in the banking industry and has tons of money, he took a similar device and charged a fortune for it so it would not become widely used. Elon is in on all the big hoaxes - like the space program - he never delivered on his promises but talks a big game. The wealthy had to control the device; they would not let it into the hands of the common folks for free energy. The original equipment was meant for cars, but Dennis Lee attached a generator to use for homes. I wonder if Dennis Lee is still alive or if they have labotomized him. He was, evidently, before his time, but enough of us know what we experienced in the demonstrations. He did his job to wake up millions of people to the possibility of free energy and to help break down the existing power structures. Does anyone know if he is still alive? He did get very very stupid after visiting Washington. I can only assume they threatened him with simple torture and death tactics, or even chipped him. I invite you to stop judging without knowing.
