More reasons to avoid an EV ... https://www.reuters.com/business/autos-transportation/ev-batteries-remain-major-challenge-insurers-uks-thatcham-2023-07-04/ A 50ft exclusion zone around a damaged one parked and waiting to be repaired? Nice. Also, if a dented bumper might cause an insurance...

That's just the emissions involved in manufacturing one. When it comes to the per-mile emissions from actually driving one? That zero CO2 coming out of the non-existent tail pipe is the feel-good end-user number which conveniently forgets to include the pollution produced by the powerplant...

In theory you can take spent fuel and remove all the fission and decay products (some of which - like Americium-241 - are useful in their own right). In practice? Budgets aren't unlimited and it's not cost effective to do that with all the spent fuel. The "bury it someplace deep and...

Remember, everyone on both sides of the climate "debate" has an agenda. A lot of the reeing is the result of "stop liking what I don't like" getting taken to eleven and routed through a megaphone with a side order of grift tossed in for good measure Practically any "independant" scientific...

Historically CO2 levels have been in the 170-300ppm range since before humans were a thing. We are not suffering from a CO2 shortage.

The manager of the help section most definitely did not create money out of nothing. It just looks like the bank did to people who don't understand basic accounting. Due to the nature of double entry bookeeping assets and liabilities always match. By adjusting Tim Pool's account to have the...

Hydrazine is also very expensive. Per the DoD for FY2020: "We'll pay $89/lb." There's a reason it's not used as fuel for practically anything but a rocket motor.

Those fighting the war on end-user CO2 emissions don't care about the big picture environmental impact which includes all the other polution, waste, and environmental disruption which comes along for the ride when you try to make everything all-electric. If they did they'd be calling for stuff...

Heat pumps move heat from someplace cold to someplace hot. If you compare only the electricity a heat pump consumes when its running to a gas furnace it's a great "green" solution. Toss in everything it takes to generate that electricity and they lose a lot of their luster.

Idiots. Natural gas heat is vastly more efficient and less polluting than electric heat in the grand scheme of things. A big powerplant is going to top out at about 45% before line losses get included. Gas furnaces? 95%+ for a high-efficiency furnace.

You're not running a furnace, water heater, oven, or stovetop on 1kW unless they're gas appliances.

Physics gets very weird when the quantum interacts with relativity. Hawking radiation, for example.

... I have an engineering manual from 1989 in my car: ASHRAE Fundamentals. Chapter 24 - which is 22 pages long BTW - has weather data for practically the entire world. So what? 🤷

When I was in college (late '90s) the company I worked for did energy studies for IHELA (Iowa Higher Education Loan Authority). Most of it was bullshit which amounted to recommending that old incandescent light fixtures get replaced with fluoresent ones, insulating the walls and roof, and...

The 250kW of solar which didn't get built would have been much more expensive than the 601kW supercharged 4.7L V8 my brother-in-laws '08 Koenigsegg has in his garage.

A project I worked on twelve years ago was a hockey arena in Pennsylvania. The energy code said "this must have 250kW of solar panels". Yeah, that didn't happen and it got built without any solar panels.

Or Thermodynamics. It has laws. 1st: Energy can not be created or destroyed, only transformed. 2nd: Entropy always increases. 3rd: Heat always flows towards the lower temperature.

When it comes to an affordable energy source useful for cooking and capable of keeping you warm when it's cold out it's really hard to top the highly-renewable bit of "oh, I just found that laying around in my backyard" called wet firewood that's used to fuel an improvized bonfire which would...

From a thermodynamic and emissions perspective pure H2 is a great fuel. From a practical perspective - except for certain niche applications like big rocket motors - it's a terrible choice because: - it's a pain in the ass to handle - it leaks through damn near everything - it boils at -252.9C...

That's thermal output, which a locomotive doesn't care about. Those care about shaft output, which for a Virginia's plant is ~80,000hp.
