#4thgrade science lesson about determining viability of #alternativeenergy sources today. It turned into an unexpectedly sophisticated conversation about long term cost/benefit reckoning, environmental impact, and #watersovereignty. “But if we build dams, what if there’s not enough water downstream for other people? People won’t want to share if they’re making money.” #sw kids think about this. Almost made up for my #teacherfails accidental cock-and-balls shaped #math models earlier in the day.

A new solar cell coating generates electricity from the friction of raindrops, so electricity is generated both when the weather is sunny and when it's rainy.

Probably not something that can be deployed on a global scale, but in the right spot, to serve the local population, it can be something to consider.

Also, anything at this point to rid ourselves of Big Oil and their devastating wars.

Trump's attacks on offshore #WindPower could hurt infrastructure spending across the economy - oil and gas prices soar while #Trump pays a French firm $1 billion in taxpayer funds to stop offshore wind power developments. Doesn’t make any sense at all. #energy #EnergyCrisis #AlternativeEnergy https://www.npr.org/2026/03/26/nx-s1-5760979/trump-offshore-wind-climate-change-energy

Because of differences in the energy of sunlight of different wavelengths, solar cells capture only about a third of the energy present. A new molybdenum-based complex allows capture of 30% more.
