One heat source can provide electricity, space heating, and hot water all at once, in one loop, without needing to buy 3 separate systems to do 3 separate jobs. That is the entire point of the Piggy Power Ember. In this video, the heat source is sunlight concentrated through a Fresnel lens. The Ember is sitting over a bucket of water. The bottom side gets heated, the water side stays cooler, and that temperature difference turns into usable electricity. That electricity is charging my phone while the water is also absorbing the leftover heat. That is the part people miss. Most energy systems only care about the electricity and throw the rest away as waste heat. Piggy Power is built around using that heat instead of wasting it. Electricity is only 1 part of the loop. The same heat can also become warm water. That warm water can be stored. That stored heat can be used later for comfort, utility, or basic off grid needs. Solar panels are great for what they are, but they leave a massive amount of energy on the table. Piggy Power is going after total useful efficiency. Not just watts on a screen. Useful heat plus useful electricity from the same source. A candle, a fire, a wood stove, propane, Sterno, hot water, charcoal, sunlight through a lens, or almost any steady heat source can become a power source when you build the system around heat instead of ignoring it. This is why Ember matters. It takes something as simple as heat and turns it into practical power you can actually see. A phone charging. Lights running. A small pump moving water. Emergency loads staying alive when the grid is down and the sun is not cooperating. We are not trying to copy solar. We are building something solar cannot do by itself. Electricity, hot water, and space heating from 1 captured heat loop. Big Solar lied to you by making people think electricity is the only thing that matters. Heat matters. Stored heat matters. Useful output matters. And when you count all of it, Piggy Power is aiming to beat solar in total useful efficiency. In the ways that matter most for off grid life, emergency power, and real world survival, we already are. This is Piggy Power. - @officialpiggypower
