This uses the sun in a very specific way to roast peppers but technically the sun is the only source of energy in our solar system, therefore everything is using the power of the sun by definition! (including photosythesis, hence fossil fuels)

- austinjp 4y agoHmmm I think radiation and gravity (thereby including geothermal heat) might be energy sources that are independent of the sun?
- osrec 4y agoBut is gravity really providing energy? It's only because of the sun that certain things are able to rise to a higher level of gravitational potential energy, and then drop back "down", thereby releasing the potential energy they had gained.
- austinjp 4y agoSpecifically regarding geothermal energy, this is available due to the gravity that formed the Earth.
- emrah 4y agoGravity is not a source of energy, it's an energy store. You need to put in energy to get back energy (at least the way i think you are proposing it here) Radioactive materials are also due to the sun, ours or others elsewhere in the universe. Earth does not produce them. Whatever heat our planet had in the beginning and continues to have, originated from the sun. No sun, no heat
