There are regulations nevertheless. The limit is 8 hrs of consecutive driving, after which a 30 min break is required, and 11 hrs of maximum driving after an 10 hrs break. It would make sense to split the 11 hrs into two 5-6 hrs periods with the 30 min rest in between. With 60 mph, this gives a driving range of 360 miles on a charge. A commercially available Mercedes eActros 600 with 600 kWh of charge would easily be sufficient, requiring a 30-80% charge within 30 mins. Or you go for the 14 hrs total, and split the 11 hrs of driving into them, giving you for instance a 3 hrs drive/1 hr rest rhythm, and requiring you to recharge for 180 miles during the stops, which means that you could drive that schedule by charging solely at 350 kW chargers.

You don't actually need an MW charger to recharge a semi. Any normal car charger will do. And while most of them max out somewhere around 400 kW, it's still plenty to go from 10-80% in about 40 mins. Just do the math: 400 kW for 40 mins is about 270 kWh, or about the amount you need to go from 10-80% on an 400 kWh battery. That would be sufficient for about 250 miles with a semi.

German YouTuber Elektrotrucker does international hauling throughout Europe for more than a year now, and he regularly recharges at a normal car charger.

You can put solar panels on roofs. I wonder if someone ever had thought about it.

Everyone has the right to be a political activist. That includes scientists. You want to cut the ability of scientists to speak their opinion. And that's a bad thing per se.

In jurisdiction, there is the principle: Ignorantia legis non excusat. We should apply the same principle to science. Ignorantia scientes non excusat. Being wrong about science is not an opinion. It's something you could rectify by educating yourself about science, in the same way you educate yourself about the legal situation before deciding something important. No judge will excuse you for having a "different legal opinion" about something that is clearly stated otherwise in the law. We should do the same for science. And if you don't like the way scientists are of a different opinion than you about the possible outcome of a political decision, it's not because they are activists, it's because they know something you want to ignore.

There is no such thing as "plain Lithium-Ion". Lithium-Ion is a catch-all term for accumulator cells which use Lithium ions in anode, cathode and electrolyte. There are many versions of them. The oldest type is Lithium-Cobaltoxide (LiCoO2), which uses Cobalt(II)-oxide in the cathode. Then there is Lithium-Nickel-Maganese-Cobalt (LiNMC), which is often used in cars, because it allows for very dense accumulator cells. Lithium-Ironphosphate (LiFePO4), while having the same gravimetric density as LiNMC, takes up more space for the same capacity, it is a more fluffy material. We have Lithium-Nickel-Cobalt-Aluminium-Oxide (LiNCA), used in the cells Panasonic builds for Tesla. Many pedelec batteries, but also the Nissan Leaf use Lithium-Manganeseoxide (LiMO) cells.

Lets put it like this: You have to compare 80 years of biography to find out. Right now, people dying did not experience the Great Depression and the Second World War, which gives them a large boost compared to people living 10 years early. We might see the effect of Microplastic in 50 years time.

LEO is used for most satellites because it's by far the cheapest orbit, which you can easily reach with a two stage rocket. Everything above LEO needs much bigger rockets and is thus much more expensive to reach.

Kilowatt-hours are also used in countries which use the Metric System. And the S.I. units don't use camel case. It's kilowatt and Megajoules, albeit the abbreviations are kW and MJ.

Additionally, diesel generators need regular diesel transport, while a solar+battery installation, once in place, does not require outside resources. You could even transport solar panels and batteries with a motorcycle along a foot path, which is much more complicated with a diesel generator. And a solar+battery installation is easily scalable, while a diesel generator is not.

I can get a 2 kWh battery here around for 300 EUR (after taxes), and Hawaii will subsidize the same capacity with $400? I should buy a container full of them and ship them to Hawaii immediately.

My grandmother lived near an airbase, and every day, there were at least two supersonic aircraft in the skies. When they were flying above us, you could not understand the other guy talking. And we have to consider the distance in the line of sight. A starting aircraft on an airbase on the other side of the valley might be 10 miles away from you. A starting airplane right above you is quite different.

I wonder why most other nations also had a ban of non-military supersonic flight in place, nations with supersonic passenger jets, a.k.a. France and the United Kingdom, and those without, like Brasil or Germany.

Supersonic flight is incredibly noisy, and you don't want it above you.

The fact is that the catastrophe happens, no matter what. But there are people wanting to hide it for as long as possible, while others think that getting prepared because of solid information available beforehand makes some sense.

Climate change happens, and it is hanging fast, faster than ever in recorded geological times.

All's left to do is to answer three questions:

1. Do we want Climate change?
2. If no, do we want to do something about it?
3. Whatever the answers to the two questions above, who will foot the bill?

There are people wanting to dodge the questions, especially the third one by hand waving and mumbling something about economy, technological advance and the market forces. And there are people who want answers.

You could do a study in other countries and compare the results. They have the same gadgets, but not the increased hoods on their cars. Once you corrected for the gadget distraction, you will still find higher casualty rates.

Differently than common belief, the EV market in Europe is dominated by domestic companies like Volkswagen, Stellantis and Renault, with Tesla and Hyundai/Kia thrown in. Chinese manufactures recently reached a new high with 4.5 percent EV market share. And EV itself is about 25% of total market share. There is not much experience with Chinese EVs so far.
