2021-10-17 Solar Floats For Floating PV

I was thinking about a design for floats to assemble together to make a floating solar PV array. These floats would be connected together to make a long carrier for multiple PV panels. The floats would have a channel to carry cabling and cable splices. There would be holes to loop ropes through to tie

2021-10-14 Steel Mill Runs On Solar Power

Numerous times I’ve heard these doubt mongers say “… but renewables will never be able to power heavy industry.” And I tell them they don’t know what they are talking about. Now we have a real life example of it being done. https://electrek.co/2021/10/14/egeb-a-colorado-steel-mill-is-now-the-worlds-first-to-run-almost-entirely-on-solar/

2021-10-13 Wind Turbines Pay For Themselves In A Few Years

To the climate change deniers who can’t add 1 and 1. Wind turbines pay back their costs after a few years and save thousands of tons of CO2 during their lifetimes. https://www.politifact.com/factchecks/2021/oct/12/viral-image/actually-wind-turbines-easily-produce-more-power-i/

2021-10-12 Azelio Unveils Solar Thermal Storage System

The solar energy melts aluminum at 600 deg. C and runs a Stirling engine even when the Sun isn’t shining. https://www.pv-magazine-australia.com/2021/10/11/electro-thermal-storage-system-for-commercial-applications-launched/

2021-10-11 Hydrogen House Project Tour Video

This guy runs everything off hydrogen. He makes his own, stores his own and powers everything from green hydrogen. He has six patents dealing with hydrogen. He made his own system. https://youtu.be/NMH1pBAYgYs GKN Hydrogen’s HY2MINI demonstrator. This is a similar setup. The solar array powers the electrolyzer. The green hydrogen is stored in metal hydride

2021-10-08 Colossal 16 MW Offshore Wind Turbine

MingYang’s newest wind turbine << A single MySE 16.0-242 turbine will generate 80,000 MWh of electricity annually. It will produce 45% more energy than MingYang’s previous turbine model, the MySE 11.0-203. One of these turbines will be able to eliminate more than 1.6 million metric tons of carbon dioxide emissions over the course of its

2021-10-08 Future Of Green Hydrogen

From FB group reply Troy Slavant Said, “hydrogen… Is more expensive than gasoline and always will be.” You’re right about the first half, green hydrogen is more expensive at this time. But it won’t be once the electrolysis plants are built. This is one example. Note the article mentions Japan, Korea, US, Germany. Note this

2021-10-05 Renewables Plus Storage Replace Gas Plants

From FB comment re: Headwind”21 movie Alexander Pohl Said, “where does electricity come from when the wind doesn’t blow? They are building 100% standby gas for … wind…” No, they are not!! The gas turbine peaker plants are being replaced with BESS – battery energy storage systems. Search for Moss Landing BESS for an example.
