The manufacturing of Electric Vehicles and grid scale storage are constrained by the amounts of batteries that can be supplied by the battery makers around the world. The early Tesla EVs used the ubiquitous 18650 lithium ion cells, something like 6000 per vehicle. In order to reduce costs and weight Tesla went to the larger

Researchers have come up with a redox flow battery that uses organic chemicals in place of toxic and expensive vanadium. They cost less than half as much, too. https://youtu.be/YyzQsVzKylE We need to have millions of these made and deployed over the whole world to solve the intermittent renewables problem.

Bigger than Hornsdale. Is this really so disruptive of the baseload paradigm that it’s dynamite in disguise? https://www.greentechmedia.com/amp/article/ls-power-energizes-worlds-biggest-battery-near-san-diego-just-in-time-for-heatwave ***************************** Maybe a little BS? 😂👍 https://www.pv-magazine.com/2020/08/21/special-pv-plant-design-for-livestock-in-taiwan/
This is a YouTube video. This guy did a very good job of building an off-grid solar system. It’s transportable, uses four 100 watt panels, two 12V AGM batteries in parallel, can supply 120VAC pure sine wave at 2000 watts and costs under $1,900. This is an excellent video with plenty of details. He calls

I bought two of these motion sensing LED lights for my hallway. They have a rechargeable cell that is charged through a micro USB port. To see one inside watch big Clive’s YouTube video – the ebay link to buy them is in his description. The charge lasts for more than a week with frequent

From FB group electronics hobbyists Over the holidays I installed two solar 60 LED lights I bought on eBay. They stopped working just a few weeks after. I finally got up on the ladder and took them down to see why they died. Well, spit! The solar panel is plugged into the jack on the

From FB group Orange Talk, July 13 Rebecca Joy It’s still not spelled right. 😝 It’s not Columnist Manifesto. The Communist Manifesto was only a few dozen pages long and at the time was considered the most influential document of the 19th century. The evil Commies were a totally different thing. The Communist Manifesto was

From FB group Another FB member, who’s not in the groups, has also built a battery capacity tester. I think he uses a 10 ohm resistor. The typical testers found online apparently use what the battery makers say they use in the data sheets. This link is for the .PDF of the apps manual for
