But if 90 percent of the time all you need to do with a tubeless tire is air it up you are still ahead quite a bit. There are really two advantages of tubeless: 1. You can run at lower tire pressure. Sometimes much lower tire pressures. This can help with certain surfaces and give you...

That shouldn't happen if your tire is properly fitted to the rim in the first place. And no, not all 700c or 650b tires will fit properly an all 700c or 650b rims. For such extreme cases, and when you have a sidewall tear, you should carry a spare tube and a tire boot so you can at least limp...

I want an explanation! Used car sales in the Untied States so far in 2026 are down about 0.9 percent. Yet used electric vehicle sales are up 29 percent. How is this possible if electric vehicles are fake news?

Any reading of history shows that parents are really bad at policing their kids when it comes to any new technology.

I think the thesis of this thread is too broad and there are lots of easy counterexamples. Even with very precise definitions I strongly suspect that there are obvious counterexamples. One super easy counterexample of an automated safety system that doesn't destroy anyone's critical...

Those facilities are expected to be completed in about 2030 if everything goes well. So that isn't relevant to this discussion at all. Lead time on fabs is very long and even that timeline is very optimistic. Right now lead time for EUV lithography equipment is about eighteen months. Since...

No it isn't. GPUs and RAM are backordered about a year and it isn't likely you can increase the production rate quickly enough to matter. Worse, things like cooling systems and transformers are backordered out about four years. What I find interesting is that if this were real someone would...

Silicon is still getting better and cheaper and faster. Hard for anything to catch up outside of niche applications (like with gallium arsenide or indium phosphide) until improvements in silicon stall out.

You need to read history a bit more carefully. The way China industrialized in the last forty-odd years was through foreign investment. Mostly American. The way America industrialized in the late 1800s was through foreign investment. Nearly all from Europe and much of it British. I predict...

That doesn't help at all for the large numbers of people who rent an e-bike. And the fact that the interfaces to different e-bikes are often terribly different and inconsistent makes the problem worse. Some ebikes do not have a "PAS 0" setting or equivalent. Some of them won't readily let you...

If you ever go on group rides with a bunch of people renting e-bikes you will eventually see this happen live in real time. It can be very exciting and often involves a visit from EMTs.

If one can believe AI summaries, the worldwide EV market is up approximately 25 percent while in the Untied States it is down 25 percent. It doesn't take balls to figure out why. And also when you mention "balls" you seem to imply that we need to implement North Korean-style juche. In order...

How long, realistically, do you think it will be before Chinese vehicles hit the US market? This ain't North Korea or Albania. Yet. Preferences can change. Sometimes very rapidly. A lot of people in the 1970s assumed that Japanese automakers would never get a big slice of the US market and...

And another grift that was too good to last, lolz. https://www.investopedia.com/trump-linked-freedom-fuel-gas-was-too-good-to-last-12014494

Extinction event incoming. Leapmotor is a Chinese EV startup which is moving into Mexico and (soon) Canada. There top-tier B10 Compact SUV runs approximately $18000 (US). Which is less than half of what a comparable vehicle from a US manufacturer, or for that matter Korea or Japan, can...

Current off-grid systems run about $15k, and an enterprising DIYer can often manage one for half the price. So I dunno where this $50k price comes from unless you are buying it all at Niemann-Marcus and having it installed by lawyers. Or maybe that is the price in miniature Australian dollars...

TMI. Weirdest thread ever.

Except when you don't hear about it. In the Untied States 99 percent of lead is recycled, mostly from 12V car batteries. Worldwide about half of lead consumption is recycled. That example gives you a good idea of what is possible if we need to do it.

The world crude oil market right now:

Well, the cost of "$800-$1300" is typical installed cost. Replacing just the batteries is usually less than half that. Nearly all residential solar batteries sold in the states in 2026 have ten year warranties. Which tells me that if the companies want to stay in business that the average...
