You should watch videos on how hard head gaskets are to design if you want an idea of some of the engineering involved- I think "engineering explained" did one recently on youtube.

That is a fair point- although when the increases are large enough in such a small time that the prior/posterior calculations are that different, I don't feel like it inspires confidence.

Here's the data on M2 money supply in billions of dollars, for those curious, in billions of dollars: Feb 2020: 15,457.9 Feb 2022: 21,699.2 This is a 40.3% increase. To be charitable, this money isn't all on printed physical cash

I don't think any of the people you are having a discussion with are making the claims you think they are making.

I've been keeping an eye on LiFePO4 batteries- they should be less likely to have a "thermal event" than lithium ion. Some manufacturers are putting them in cars now. Less energy dense but cheaper and better cycle life before

I think if there is condensation between the panes then the sealed air cavity inside the window has been compromised- you might want to get a new window put in. The large double glazed sliding glass door in one of my previous apartments had

It is a comparison in the same spirit as the original article.

insulation-displacement-crimps are not a good idea for the relatively high amounts of power coming through household wiring. Not much contact area, lots of potential for high resistance and heat and oxidation at the contact point. I wouldn&

UK homes run on 230 volts, so each amp is worth double what US amps are worth (running on 115 volts in the US) edit: 115 volts per leg, and US has 2 legs, so it comes out in the wash, surprisingly. UK homes have tiny little service amps!

Seems to me that people are much more upset about this particular video (guy in circle for 100 days) because he's a husband and father. If it had been a young 20-something person, nobody would bat an eye.

I've only thought about it for a minute- but I might speculate that it is a signal from Russia- "even if we decide we want to turn the gas back on, you might not be able to get it when you want it."

You are confusing the watt and the watt-hour. Running a 2000 watt load for 24 hours will use 48,000 watt-hours (48 kilowatt-hours).

I'm not sure how things will look by the time my daughter might be ready to go to college in 18 years- Would it be best for us to sock away money in a 529 plan, or to just let her take out loans to the greatest extent possible and pay

You conflated some of my claims about the hypothetical company with claims about Microsoft in particular. I think that the root of it gets down to disagreement in values about how capitalism rewards innovators though, so it's unlikely

I think we're seeing the culmination of a long-term trend of declining interest rates. Interest rates have been declining for 400 years, and have finally reached the point where they bottom out at 0. (or even negative interest rates, i

As a pure test case- Let's say there was an individual who founded a company, owned 100% of the equity, and designed a brand new product. The product solved an unmet need for consumers, sold at high profit margins, and was massively su

You're free to give as much extra taxes to the government as you want to help reduce the debt and get us closer to that sovereign wealth fund. I'd appreciate it.

Isn't heating a really good way to use natural gas compared to other ways to use it? 90%+ efficiency ain't bad.

That 20,000 number is off by at least an order of magnitude just for US bird wind turbine deaths. Turbine construction has been accelerating, so the 2013 numbers cited below are low. https://abcbirds.org/blog21/wind-tur

There should be no risk to using untreated water to flush the toilet. Presumably they are shipping two types of water- potable and non-potable. The non-potable is less difficult to produce and ship. You can flush a toilet by dumping a bucke

Is PV at the same land use as coal currently on a per-watt basis or on a total land use basis?

Gasoline engines struggle to produce torque at very low RPM's, so once they begin choking on the fibers in the chaps, they lose momentum and stop. Electric motors on the other hand produce peak torque at 0 RPM, so it's way harder

If the city can buy property at 90% of appraised value, they can sell to the market at true market value. As long as their appraised value is accurate, they profit from this arrangement. It provides the proper incentive to align appraisals

The amount of solar power hitting the surface of a car is much, much smaller than the power driving the wheels.

I've been expecting Germany will turn their nuclear plants back on soon, given the Ukraine situation. Haven't seen it happen yet though.
