Winter is fast approaching and saving money on the heating bills is always a good thing. This DIY project is perfect to keep you warm in the freezing weather and maybe just maybe be more valuable than you think.
If SHTF and you had rechargeable batteries and a solar charger this could be an unlimited free heat, this would heat a small room and car enough to take the chill out the room and any amount of heat would be morale lifting too. Check out how to make this simple project below and please tell me your comments over at our Facebook page.
