I’m curious as to what people are doing with their spare solar power.

I’m in the US and on NEM2. I already have batteries and discharge them when the rates are favorable.

But I still have a lot of leftover juice. My partner recently bought an EV but doesn’t drive much.

I set up a home lab and even bought a small bitcoin miner that turns on when electricity rates are favorable.

I've been using it to build cellulose, sugars, and other organic compounds from CO2 and water. I get oxygen as a byproduct too which is neat.

[–] Valmond@lemmy.dbzer0.com 9 points 1 month ago (1 children)

I'd love to hear how you do that!

I believe that @cattywampas@lemmy.world is growing plants, the old-school solar route.

Thanks, I was imagining some kind of high tech lab setup.

It's actually future tech alien magic that we humans cannot even begin to replicate in its efficiency and self-sustainability.

[–] Mantzy81@aussie.zone 3 points 1 month ago

You can set up a lab if you want. Grow something in a petridish.

[–] mohammed_alibi@lemmy.world 2 points 1 month ago

It's pretty high tech. The greatest minds on earth is unable to recreate it from scratch.

[–] Valmond@lemmy.dbzer0.com 3 points 1 month ago

Ha ha got me right there, well done!

I'm sure they're talking about LED grow lights run by solar power.

[–] IlmariGanander@lemmy.wtf 6 points 1 month ago (1 children)

We can't rule out that they may be a plant.

What about THC as a byproduct ? ( ͡~ ͜ʖ ͡°)

You don't have to do the "sharing a secret" wink anymore when mentioning marijuana. It's mostly mainstream now and the pre-legal cool factor is gone. I know it's not legal everywhere but the gild fell off that lily a while ago.

[–] venusaur@lemmy.world 1 points 1 month ago

If you’re saying power indoor growing, then yes I’d agree. Those lights use a lot of energy.
