2020-11-11 Redox Flow W/O Vanadium; Chinese Anti-Capitalism Economics

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. Chinese Anti-capitalist economics The capitalist way

2020-08-20 Biggest Battery In US

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/

2020-07-11 DIY Off Grid Solar System

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

2018-01-29 Battery Capacity Testing

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
