This is a prototype FM radio in a mason jar tuned tp 93.5FM “The Moose’ in Haliburton, Ontario. It runs on solar charged graphene capacitors instead of batteries and gives about 3h of play, easily recharging daily in a sunny window. Graphene capacitors recharge 100,00 – 1,000,000 times and can last 20 years. This will never use more energy than is available – it is a sustainable consumer product.
