Horse and buggy is more sustainable than either ICE or EV. It's about the most efficient way to convert the power of the sun into forward movement!

- Const-me 5y ago> the most efficient way to convert the power of the sun into forward movement Very inefficient, and the difference is several orders of magnitude. A horse needs 2-40 acres of land: https://horses.extension.org/how-much-land-do-i-need-for-a-horse/ https://horses.extension.org/how-much-land-do-i-need-for-a-h... Photovoltaic panels can generate 500 kilowatts on 2 acres. Tesla's V3 supersharger is 250 kilowatt, adds 170 miles in 15 minutes of charging. If the sun is shining for 6 hours, photovoltaic panels on 2 acres charge Teslas to drive 8000 miles. For a horse, the figure is like 40 miles per day.
- ppf 5y agoHorses take a lot less energy and rare minerals to produce than Teslas, superchargers, and solar panels. Edit: You can also do multi-level agriculture, unlike solar panels https://en.wikipedia.org/wiki/Silvopasture https://en.wikipedia.org/wiki/Silvopasture
- Const-me 5y ago> Horses take a lot less energy and rare minerals to produce They take 4 years to produce. They eat a lot during that time, that's a lot of energy. Horses include some weird minerals too (copper, molybdenum, nickel, cobalt, strontium, chromium, selenium), biologists call them "microelements". > unlike solar panels Same with solar panels: https://cleantechnica.com/2020/11/19/solar-panels-agriculture-you-aint-seen-nothing-yet/ https://cleantechnica.com/2020/11/19/solar-panels-agricultur...
