From TSLA group – about hydrogen from my blog previous to this one. Nick Carrière Said, “…fundamental flaws with hydrogen vehicles…” Well, first off ‘converting to AC for a motor’ is necessary for battery EVs, too. But the losses are only a few percent either way. Said, “Total energy losses are several times higher…” That

Which pollutes more? This video shows how much the oil and gasoline industry pollutes. https://youtu.be/1oVrIHcdxjA
From my FB reply to many negative comments by this hypercritic. Ned Goldston *No* EV owner needs to have a solar panel system to charge their EV with green electricity. In California there are no coal power plants and the natural gas plants are being replaced with peak shaving utility scale batteries. At times of

My replies to article cited by an “electrical engineer with 34 yrs experience”. https://returntonow.net/2021/02/09/the-spiraling-environmental-costs-of-lithium-batteries-could-rival-fossil-fuel/ << Ned Goldston Thanks for the link to the article. The article is written with false information (e.g. li-Ion batteries cannot be recycled), the reference used is at least 8 years out of date, and the most telling is the last

Cathie Wood talks about EVs at about the 20 minute mark in this YouTube video. The first part is economics. She talks about digital wallets. She thinks 200 million digital wallets in the US, and it will put financial institutions in harm’s way. As part of automation, she talks about autonomous ride hailing. She says

A solution to adding pollution control to jet engines. https://interestingengineering.com/mits-new-hybrid-electric-plane-could-reduce-aviation-pollution-95-percent
This setup just charges the battery as long as the resistor is connected to the field coil. There is no regulation of the charge and it can overcharge the battery. To properly regulate the charging, the alternator should have a regulator instead of the resistor. The regulator will shut off the charging when the battery

The blog in the link https://ochistorical.blogspot.com/2020/12/street-car-construction-reveals-street.html?m=1 said, “The demise of the “Red Cars” was not a conspiracy, as some (including the film Who Framed Roger Rabbit) suggest. It was just a matter of the unavoidable market forces of supply and demand, combined with the march of time and technology.” This is false according to the

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

It’s amazing how there are plans for the near future for dual fuel engines that can use diesel or hydrogen. These engines can be used for railroads or marine, or for generating electricity. The 1 MW engine is equivalent to about 1350 HP. Here is a quote from this article: >> At a press event,
