FEMA says buy candles. Mine charges a DeWalt battery.

You were taught that a candle was made to smell good, sit on a shelf, and give you a tiny little flame when the power goes out. That is only part of the story. A candle is stored energy. Most people never think about it that way. They look at the flame, they see a little bit of light, maybe a little bit of heat, and that is where the thought ends. But that wax is fuel. It sits there for months or years doing nothing, and the second you light it, all of that stored energy starts coming out as heat. Normally, almost all of that heat just floats away into the room. So I built something that grabs some of it and turns it into electricity. This is the PiggyPower Ember running from candle heat. The flame heats one side of the unit, water keeps the other side cool, and that temperature difference creates usable USB power. In this video, that power is charging a DeWalt battery. No wall outlet. No gas generator. No solar panel waiting for perfect weather. Just a candle, some water, and a little bit of engineering that makes the heat actually do something useful. That is what makes this so cool to me. People already have candles. They are in drawers, closets, basements, campers, cabins, churches, sheds, garages, emergency kits, and probably half the houses in America. The energy was already sitting there. We just gave it somewhere better to go. A candle can still be a candle. It can still give you light. It can still sit there and burn. But now, with PiggyPower, that same flame can also help make electricity. That changes the way you look at emergency power. Link in bio.
