15 Watt Tube Powered by Earth Battery!!
This is a 15 watt 18 inch long tube illuminated by my modified Fuji Joule Thief circuit powered by my earth battery. The light was better than I expected. I am also using two 2.3 volt 10 Farad supercaps in parallel with the Joule Thief Fuji circuit. For more info go to Overunitydotcom in our Joule Thief topic. Thank you for watching. Bill
