DIY Renewable Energy Solutions: Aluminum-Air Batteries & Saltwater Lamps (lemmy.world)

Hi everyone! I’ve been diving into alternative, off-grid energy solutions, and I thought I’d share two interesting concepts: Aluminum-Air Batteries and Saltwater Lamps.

Aluminum-Air Batteries are lightweight, long-lasting, and provide eco-friendly backup power, perfect for small-scale renewable systems. The great thing is they don’t require complicated infrastructure, just the battery and an electrolyte.

Saltwater Lamps are a simple, sustainable lighting solution that uses just saltwater to power up a lamp. They’re great for off-grid homes or emergency lighting.

Both of these solutions are incredibly easy to implement, and they could fit right into the DIY renewable energy systems many of you are working on. Anyone here experimented with similar systems or ideas? I’d love to hear how you’re using them or improving on them!

Let’s chat about integrating these into home energy setups!

Thanks for your comment! You’re right that lead-acid and lithium batteries are less polluting due to their rechargeability. Regarding the shelf life, you’re correct that all batteries last longer if their electrolyte is kept separate.You look like a battery expert.jajaja
