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!

Not all the articles are about renewable energy but they are all interesting to read.

I've been watching the channel for a few years now and find the setup fascinating. Also many more great videos on his channel so highly recommend.

Some of this stuff would be very easy to copy or modify.

An article from PennState Extension. Click the link for more.

Roof-catchment cisterns may also be used to supply water to farms. Watering troughs and rain barrels can be filled by water collected from barn and other out-building roofs. A storage cistern built alongside a barn or other building could serve as an emergency source of water for firefighting in the event that a pond were not nearby. However, the use of rainwater for supplying domestic water needs is not without its problems.

Water quality is of concern especially when the rainwater is to be used for drinking purposes in addition to other domestic uses. Rainwater and atmospheric dust that are collected by roof catchments contain certain contaminants which may pose a health threat to those consuming the water. Lead and other pollutants may accumulate in cistern bottom sediments; and untreated rainwater is quite corrosive to plumbing systems. Measures must be taken to minimize these and other water-quality problems in cistern systems. Recommendations for doing this will be presented, as well as guidelines for designing and building roof-catchment cistern systems.

Rainwater cisterns can provide water of adequate quantity and quality if proper steps are taken in the planning and construction stages, and periodic maintenance is performed throughout the life of the cistern.

This looks like a fun little project that I think people here would enjoy! I have a little stack of tin foil takeaway boxes that I could use for this. Just need to get hold of the plexiglass (or the oven bag they suggest, but I'd like to do it entirely with reusables if possible).

EDIT: Grammar.

Pysolar is a collection of Python libraries for simulating the irradiation of any point on earth by the sun.

Another great resource on setting up and using pelton wheels as part of your home-made renewable energy system.

This blog post/video shows a simple but effective home made hydroelectric system that has been running for 16 years in New Zealand.

A good page to get a handle on what Pelton wheels are. They can be 3d printed, made from soft drink bottles, PVC pipe, etc... In theory, Pelton wheels are a very efficient way of turning water with a fair bit of head (pressure) into mechanical energy.

I think this community might be having issues with visibility, possibly to do with language settings. If you can see this, can you give a quick comment? Thx.
