There are ongoing topics to do with the Green New Deal, Global Warming, Climate Change and Power. Here are some links to "small nuclear reactors". They are clean, they pose no threats, environmentally and just plain safe and cannot melt down, etc.

these things could replace the windmills (and save a lot of birds) and all coal, and petroleum fueled power plants.
can be delivered from factory to site by truck
need no human intervention
can actually use existing nuclear waste as fuel as well as other fuels
Some countries currently building or are considering them:
China
United States
Canada
France
Germany
Russia
India
Argentina

WASHINGTON — The Pentagon on Monday issued three contracts to start design work on mobile, small nuclear reactors, as part of a two-step plan towards achieving nuclear power for American forces at home and abroad.

The department awarded contracts to BWX Technologies, Inc. of Virginia, for $13.5 million; Westinghouse Government Services of Washington, D.C. for $11.9 million; and X-energy, LLC of Maryland, for $14.3 million, to begin a two-year engineering design competition for a small nuclear microreactor designed to potentially be forward deployed with forces outside the continental United States...



That is fantastic.

There are questions about this one. What fuel? What does 'micro' REALLY mean (we already have 'modular' and 'small') I ask that one because it would seem, to me, that the oil folk will have a genuine fit it 'micro' might be right and we are really talking about engines for trucks (for starters).

I can remember when gov was developing a nuclear airplane. If I remember correctly they actually had a working model before that one got shut down. Fossil fuel industries have a LOT of power! This was real and got shut down. It was even in the papers of the time. Oh, it happened at least 20 years ago! Google "nuclear airplanes" for a lot on this one.

This all started, several years ago, with a "modular reactor" about the size of an 8 seat hottub that could be buried in the earth to supply electric power for between 20 and 30 years and then dug up and replaced. The company with that design gave up on the United States and moved to China where they were welcomed with open arms (don't remember what happened to that one).

This reminds me of an old sci-fi story. Somebody invents a very small nuclear generator that can run a truck. Gov learns about it and tries to stop it. Trucks still get the engine which includes a way to generate truck motor sounds so nobody knows. Gov finally loses and heroes emerge. Etc, etc., etc.

Sounds like a Randian fantasy. The problem with nuclear trucks and planes is that those things tend to crash and would break open, creating a real mess. Much safer to make them stationary. Or just use the power from much larger, more efficient plants to make ethanol from crop waste to power those trucks and planes.

We already have all the infrastructure to distribute ethanol in this country.

Navy's been using little tiny reactors right along but they've got unlimited sea water to cool them. It's looking like a lot of research is being done into this right now. All of a sudden everybody is talking small reactors. Electric cars mean everybody's gonna get their transport energy from the grid. Power providers are gonna have to ramp up production and fossil fuels are gonna be the loser in this race.

Is anybody running any nuclear powered container ships? Perhaps they soon will be.

Yes, that is a serious look, a project to fill a clearly identified and defined need at this stage is a sure bet, if nothing interferes, to become reality.

Back in the 80s they were talking about small, mobile reactors and thermo generators to power the tactical side of things. Cheaper and easier to ship a power generation setup than to have oil tankers (slow, big, and sure kill targets) sailing across the ocean. That is a logistics tail that every commander would want to get rid of.

The article keeps talking (implying) the use of uranium or other hazardous nuclear fuel... Where is the safe (relatively) stuff?

I am REALLY against ethanol. We already pay 4 billion in subsidies every year for the privilege of wrecking our car engines and raising, internationally, the price of corn. On top of that its just not good for the environment.

you are, absolutely, right on this one. The follil fuel folks are going to be demonizing 'nuclear'. Just watch, there will be tv shows and movies showing how 'nuclear' will destroy the world as well as other wonders to behold before its all over.

The fact remains, backed by any number of designs, that this stuff is seriously safe, environmentally friendly, cost effective, etc. There is no reason why this stuff couldn't be reduced by a lot and probably/virtually indestructible.

(I know, too far, its what enthusiasm gets yuh <g>)

Ethanol really requires an engine retool, despite arguments to the contrary, but even if "Flex-Fuel" engines work, as they sometimes do, the ERoEI is a negative, such that even cellulosic ethanol is still a nonstarter even after twenty-plus years of effort to make it viable.
And yes, ethanol does wreck conventional engines.
It even wrecks racing engines to some extent, but the motorheads building racing engines don't really care about longevity beyond 1320 feet, do they?

We can do a lot better than ethanol..we do not have the vast sugarcane fields required to make it, although with the recent hand sanitizer shortage maybe some domestic sugarcane fields might be a good idea...but not for automobile fuel.

Nuke cars? Hell no, why not just improve battery tech some more?
The old arguments about battery tech are dissolving as new battery formulations come online.

The old arguments about range anxiety and recharging are dissolving, too.

Conventional engines will soon be a thing of the past. Ethanol might still find some use in the small engines industry but it's probably destined for extinction, we never needed it to begin with.

There's no need for atomic cars when everything just plugs in to charge. No need for fuel tankers either, no need for refineries.
No need to drill in arctic waters.
