It melts more of the snow and ice, and that reduces the albedo further. We absorb more heat energy . And so this is why this feedback loop is why climate scientists are so concerned about what seem like relatively small changes in temperature
One of the most important ones is called the ice albedo feedback. So the albedo is the amount of heat energy that is incident on the Earth from the Sun, which gets reflected back into the atmosphere. Typically, white surfaces like snow and ice, they reflect more heat energy .
means that there's more dark area exposed and less white area. So we absorb more of the heat energy into the Earth, which then increases the temperature. It melts more of the snow and ice, and that reduces the albedo further.
A really efficient three-stone fire is, at best, only about 15% thermally efficient. That means 85% of the heat energy never reaches the pot. Our stove, from the moment heat energy is generated, forces heated air to flow up through the stove, following a path that provides maximum opportunity
But we don't know all the details of how it functions now, because the thing about an ocean, a liquid engine, is that it is an engine. It's something that converts energy, heat energy , into movement. That's what engines do.
So that for any one given cooking task, the user only needs to feed half as much fuel. But it gets even better than that because as the fire builds and more heat energy is released, more electricity is generated, to the point where it's more electricity than is required for the fan.
That means 85% of the heat energy never reaches the pot. Our stove, from the moment heat energy is generated, forces heated air to flow up through the stove, following a path that provides maximum opportunity for heat exchange with the cooking surfaces to the bottom of the pot, and then along its sides as well.
Typically, white surfaces like snow and ice, they reflect more heat energy . Dark surfaces like the land and the sea, they reflect less of the heat energy . So what can happen is if we get even a sort of small change in temperature caused by us on the Earth, which melts some ice and snow, that
They use the same fuels, whether it be wood or crop residue or even animal dung. But the difference compared to the open fire is that when they light the fire and heat is released, a small portion of that heat energy is converted into electrical energy.
So the albedo is the amount of heat energy that is incident on the Earth from the Sun, which gets reflected back into the atmosphere. Typically, white surfaces like snow and ice, they reflect more heat energy . Dark surfaces like the land and the sea, they reflect less of the heat energy .
and it was the same feedback loop just operating in reverse. The global temperature decreased a bit, which meant that there was more snow and ice that reflected more of the sun's heat energy back and absorbed less of it, so the temperature dropped more.
So we'd rather burn it to completion than just dump it outside. So we feel like it's better for us to go ahead and burn that charcoal to completion, give them all that heat energy for cooking.
Now, this stove's been designed to best run on small amounts of small wood-- little sticks that can be sustainably harvested. In contrast, open-fire cooking for institutions tends to require large amounts of large wood to generate enough heat energy for the large pots they use. Most of this energy is wasted.
