A lot of the electricity probably came from burning natural gas at the power plant, and then some of that (~5%) gets lost in transmission. If we assume the natural gas plant is 60% efficient at turning gas into electricity, then an electric heating element in a hot water tank at your house would be about 55% efficient.

A typical gas furnace is about 80% efficient at turning gas into hot fluid, and a good one can reach 95% efficiency.

Depending on the fuel mix of your local grid, there’s a good chance that burning natural gas at home will result in less pollution than using electric resistance heaters, either for heating water or the air inside your home during winter. Places like Washington state that generate most of their electricity from hydroelectric power plants will be exceptions.

However, heat pumps can be higher than 100% efficiency. They don’t use electricity to generate heat, they just move heat from one place to another. You’ll produce fewer emissions overall by using an HVAC heat pump to heat your house, and a heat pump water tank for hot water. Even if you live in a place like Canada, you can reduce emissions by installing a dual-fuel system that will use electricity to run the heat pump weather permitting, and fall back to using gas when the outdoor temperature goes too far negative.

Using heat pumps to move heat from outside, to inside your house, to inside your hot water tank is more efficient than using gas to heat your home and water, even when the electricity to run the heat pump is generated by burning natural gas.

OP could have a well.

Back in the day it was the best at what it did, but there’s less demand these days for that kind of old fashioned search.

Its still better than the competition at finding the URL of a corporate or government entity. Its still helpful for searching other websites for particular content - for example, the wikis for some games have an obtuse layout and unhelpful search function, and google can be the best way to find a particular page in that wiki.

Before ChatGPT existed, and before the enshitifaction of Reddit reached the critical level its at today, google searching site:reddit.com was pretty good at finding organic human conversations that provide actual answers to your questions.

Today however, ChatGPT is better at providing useful answers to whatever questions you may have. And Bing is better at image search.

If the sun became a red giant tomorrow, and Earth found itself inside the outer layers of solar atmosphere, then drag would start slowing it down. In less than 70,000 years, it would fall close enough to the center to be torn apart by tidal forces like one of Saturn’s moons (assuming it hasn’t already been vaporized).

If we’ve already waited 5 billion years to have our revenge, whats another 70k? The lowest amount of Delta V we can spend on this project is zero.

Sagittarius A* would like a word, and you’ll never get that word back.

What if we catch a gravity assist off Jool, and do the retrograde burn at perijool to gain some free Oberth Effect DV?

it’s the bees knees when you’re married - cream pies all day, every day

That’s what she said.

Good point about the vanes jamming in their sleeves potentially being a problem at startup. As RPM increases, centrifugal force will make it harder to retract the vanes, so they might need some kind of powered actuation beyond just a passive spring.

I imagine there would be no contact with the engine wall, just a narrow gap with an active system to adjust the size of the gap, similar to some jet turbines. The video goes into it a little bit at this time:

And someone in the comments who has experience with building this kind of engine talks a little about how its difficult but not impossible to lubricate the seal with a higher viscosity fluid that will want to build up and prevent a vane from fully extending at high RPM. A different comment points out that piston rings experience similar problems with carbon and grit.

As the operator of the other circus once said, “all publicity is good publicity,” and “there’s a sucker born every minute.”

And as the other clown, Dr. Strangelove, once said, “the whole point of a Doomsday Machine is lost, if you keep it a secret!”

The idea of a Federal cemetery being “sacred” and the strangers buried there being “honored” is so far removed from the every day fight for survival of the average, brutally exploited wageslave American, the notion that starting a fight there could budge the needle on an election lacks credibility. However, injecting the knowledge into the global zeitgeist that there’s a cemetery in America where rows of uniform gravestones extend as far as the eye can see, marking the depths of USA’s brutality and Will to Power - that sends a message.

if its going to be Republicans either way, why even show up to vote?

so vanishing they’ve become completely invisible

Seems like an interesting option for naturally aspirated race cars. They let you hit high RPM without worrying about valve float and without using overly powerful and lossy springs.

The difficulty of keeping them sealed suggests they’re less than optimal for high boost turbo applications, or high compression, fuel efficient commuter engines. Narrow tolerances may also increase manufacturing costs and decrease longevity, which is less of a problem for a race engine compared to something designed for mass production.

Some people find hydrostatic equilibrium aesthetically pleasing.

Rap sniches…

Maybe you could explain to the administrators of Kursk how its not important to defend the border 😂
