Waterwheel, then, no?
- anonporridge 5y agoA waterwheel is just hydro power, which is itself just an indirect form of solar power.
- lostapathy 5y agoTechnically every form of power is an indirect form of solar power.
- xxpor 5y agoNot nuclear! :)
- lostapathy 5y agoAll elements used in fission reactors can only come to be due to supernovae. So I guess not from our sun, but another star.
- eru 5y agoNot fission nor geothermal nor tidal power, nor fusion, if it ever arrives. But most of the other ones. (You can say that some of them, like fission, rely on heavy metals produced sort-of in a star. But still that wasn't from our sun.)
