I’ve seen so many locations in Southern California that are pretty much barren mostly because the country is lacking water. The cost of water in So. Cal. is high because there are so many people that the water they need has to be imported from hundreds of miles away — as far as Northern California.

What do we have to do to wake people up? This is a good article about actions we, the whole world, took decades ago to stop acid rain, ozone depletion, etc. We have to take action again with climate change! NOW!! https://www.theguardian.com/environment/2020/oct/12/climate-crisis-campaigns-pledge-real-change A quote from this article: >> But a changing political discourse in many

This morning on CBS Sunday Morning they had an article about a farmer who couldn’t repair his $800,000 John Deere tractor and lost several days of work. There is a growing movement in the US to make laws that require manufacturers to allow their customers to repair the equipment they own. This is a backlash

The Gencell A5 can power a cell site for a year 27/7/365 from a 12 ton tank of anhydrous ammonia. The tank is not pressurized and is at room temperature. The system converts ammonia to hydrogen and nitrogen and the hydrogen powers the fuel cells. https://www.gencellenergy.com/markets-applications/off-grid-power/
This self-contained system uses solar PV panels as the only power input. It generates and stores green hydrogen, then uses it later for both electricity and heat. The fuel cell’s byproduct is water. One important “problem” that I see is that this system makes the customer completely independent of the electricity _and_ gas utilities. There

My comment on YouTube video https://youtu.be/lL6uB1z95gA After actively disparaging renewables, he says, “I’m not actively disparaging renewables…” He makes this big stink about how renewables take up so much more land than nuclear. This is totally irrelevant! Farmers in Iowa, Nebraska have the wind turbines out in the middle if their crop fields; no problem.

From a comment on JHAT #123 about geothermal heat pumps @Donald McCarthy Demand is projected accurately by the utilities and the grid is upgraded to take care of the demand. The problem is that the growth is being offset by the retirement of older power plants that cost more than renewables. What must be done

My comment to a YouTube video. Like Tom says, “in my opinion…” There will be an upward trend in the production of green hydrogen and consequently a downward trend in the cost per kg. Large fleets of heavy vehicles can be converted from diesel to hydrogen, and it has the advantage of faster refueling than

The Energy Storage Systems makes a flow battery that is rated at 50 kW and 400 kWh. The battery uses non-toxic Iron and Water. The battery has no capacity degradation over its lifetime – it puts out the same amount of power. This YouTube video explains more. https://youtu.be/HmtI8Wat7rY
This 4.7 min. TED Talk Youtube video dispels the myth that solar and wind can’t do the job without “base load” power. Amory Lovins is with the US NREL, and is an authority on this subject. He also states that renewables are less expensive than fossil or nuclear power. https://youtu.be/Oo8iEL6SqgI
