- 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.)
- robocat 5y agoA hydro lake is exactly like a battery - potential energy filled by a river. Also if Germany sends excess wind/solar electricity to Norway, and the hydro lake is emptied slower because of that, then the hydro acts exactly the same as battery storage — no pumping required. However some lakes have a minimum rate of outflow: when rivers need a minimum flow for sports, ecological, or downstream dam capacity reasons. Also during dry periods when lake capacity drops, the ability to be used as a battery also drops. https://news.ycombinator.com/item?id=28898426 https://news.ycombinator.com/item?id=28898426
- apexalpha 5y agoWhen you actively pump water up into a hydro reservoir when you have too much electricity then it becomes a battery.
