Apropos of nothing, $25 added to a barrel is a carbon tax of about $58/ton, but in the pocket of the producers left standing rather than the public.

Same for me and my brother, age wise, but we did know he got it.

Then there are Stirling engines. This approach has been largely abanadoned.

You can also look at what Fourth Power and Antora are doing using TPV to recover electricity from stored heat.

Geothermal Energy is Poised for a Big Breakout - Eavor Eavor was recently mentioned in an excellent piece from Cloud Clarity 360. β€œClosed-loop geothermal systems have been around for decades, but a few startups have recently amped them up with technologie...

Yes they are

"Without the parasitic load of a pump, Eavor can make profitable use of relatively low heat, around 150Β°C, available almost anywhere about a mile and a half down"

My interpretation was 50% higher (so in geothermal that means going from like 12% to 18% efficiency) due to their non-water working fluid, and possibly lower parasitic loads from injection, etc.

Well, between the precipitous drop in migration and the full assault on life expectancy, the Trump administration will make 2.8% look ambitious.

Potentially weird outcome where Trump, somewhat like Putin in Ukraine, accelerates the clean energy transition more than anybody, but through the dumbest, most painful way possible.

Crude is way up from the low 60s we have been seeing lately, but still nowhere near "invasion of Ukraine" territory.

If this escalates into attacks on water infrastructure (on both sides), it could set off the humanitarian crisis of the century.

An oil company quietly dug a surprisingly deep geothermal well Oxy drilled four miles down in Colorado, and did so quickly β€” a promising development for the geothermal industry.

I saw a fresh Canary Media article on that, but haven't had a chance to read it. 4-mile depth, pretty impressive. I am not going to hold my breath for oil companies to transition, but to the extent they do, I will take it.

Rodatherm Energy wants to make geothermal more efficient, but will it be cheaper? Rodatherm Energy emerged from stealth with $38 million in Series A funding. It plans to build a closed-loop geothermal power plant that uses refrigerants to move heat to the surface.

finance.yahoo.com/news/rodathe...

This article also introduced me to Rodatherm, another player in the closed-loop geothermal game. They are building a pilot plant in Utah. It looks like they want to play in shallower sedimentary basins, which should be easier, but limiting.

Quaise looks to advance β€˜superhot’ geothermal power plant in Oregon The Houston firm aims to raise $200 million to develop a next-generation geothermal plant in Oregon as the technology gains momentum with investors.

www.canarymedia.com/articles/geo...

What Quaise is trying to pull off would be as revolutionary as what most fusion companies are pursuing if it becomes consistently repeatable. Blast your way deep enough to set up a dispatchable clean thermal plant anywhere on Earth.

Starting with 50MW in Oregon.

Pretty necessary if you're going to colomize the moon (assuming you'd want to do that). Not sure what the cooling design looks like, especially during the two weeks of day.

I'll take a nuclear plant, too, if someone wanted to build it and could find a way to cool it given our hydrology.

4. Generally, the primary local benefit is in terms of property taxes and/or economic development payments. You also get 1 or 2 permanent local jobs per 100MW (not much after construction, admittedly).

3. Indirectly, in a time of load growth driven by data centers, EVs, heat pumps, and industrial electrification, everyone on the grid benefits financially from expanding capacity. Solar also reduces the amount of gas we have to burn, and insulates us from fossil fuel fluctuations.

So the thing about power flows

1. They flow to the nearest load through the path of least impedance, meaning physically, you do benefit from the power

Model Solar Ordinance for Indiana Local Governments Local governments in Indiana are seeing increasing interest from property owners in solar energy installations and are having to address a variety of solar land uses in their development regulations. ...

scholarworks.iu.edu/dspace/items...

Check out the IU model solar ordinance, for starters.

Beware:
1. Extra long setbacks
2. Decibel requirements
3. Unreasonable screening requirements (e.g. 6 foot berm with trees on top)
4. Heat Island studies
5. Low acreage caps

The shenanigans here in 2022/2023 were

1. Add solar to the list of undesirable land uses in the comp. plan when it was specifically not on the list after we banned wind

2. Survey question: Do you approve of this undesirable list (wind, solar, porn stores, landfills, heavy industry, toxic waste)
