Again, what is a practical aircraft? If you can't define it, you can't say whether you reached a goal. An ultralight airplane is fun, but it isn't practical for most of us. Your EV is barely practical for you because you have needs outside of most of the population. I'm probably more typical...

Again, this doesn't make sense. Who has been saying this? Define productive flight. For something like a C-152/172/182, we are somewhere between 20 to 60 of 100 of the way there depending on what batteries you choose from existing ones (such as Tecnam used) to some of the newer technologies...

Tesla doesn't make real cars? The first delivery was 2008. Newer cars have more range than that original. I don't know what you are expecting, but some of the current cars have the same range as an ICE vehicle.

I'm sorry. I don't understand your question. The Chinese have batteries with longer range and faster recharge times than those available here, and some with charge-carrier ions other than lithium.

Oh wow. May as well stop all research in battery technology. What other science has reached its limits?

And that thinking is why the Chinese are so far ahead of us in batteries. I said we are a long way from those technologies leaving the lab.

Today's basic research is being done in China. They already have practical sodium based batteries in cars because of the environmental impact of lithium. They don't have the "can't be done, too expensive" mindset that you and @Salty have. That's one technology.

There are some interesting developments with high energy densities and fast charging in the lab. They would work fine for a C-182 or smaller. But they need to leave the lab and get into production. Which batteries? There's different chemistry that hasn't been tested, or just beginning to be...

Yep. And I opine some of the future battery technology would be fine for a C-172 type plane, but not something much larger or faster, where drag and energy requirements increase quickly. Tecnam has done some real work, I take their experience seriously.

You are very wrong. They are highly regulated, but there are private and joint-stock companies there as well as government owned companies. VietNam has the same business model. They are "communist" in name only. I've a friend in Suzhou who has set up her own fitness center. It is HER business...

Yes, exporting Garmin products to a prohibited nation is a violation of US law, and probably goes against contracts between Garmin and Diamond. I just checked our corporate restricted list and didn't see Myanmar (or Burma) listed as places we can't work with.. There are some restrictions, but I...

No, Diamond is owned by Wanfeng Auto Holding Group, which is generally independent of the government. The Chinese government doesn't care about EU, or USA for that matter, embargoes as you correctly state. That means Chinese companies don't care either, anymore than we care about Chinese...

It's not common. It happened to me once, in Germany. There was a vehicle on the runway causing the go-around. I also had a diversion, once, in 2007. We were over Hudson Bay and I noticed the shadows changing direction. I pulled out a hand-held GPS and saw we were going south. We landed at...

At that depth, >12,000 feet, I opine that the chances of a good outcome are slim.

Fixed, thanks.

Anyone remember the Liberty XL 2 plane with a Continental IOF-240-B FADEC engine? Certified, I think they were built for 4 years. Continental makes a Jet-A fueled FADEC diesel engine now: https://www.continental.aero/diesel/engines/cd300.aspx I think it flies on diamond aircraft.

Batteries have been getting better so now you have cars and trucks being sold with real 500-600 mile range. There still room for improvement. There are other ways to improve Li battery technology, and there are other materials besides Li. A Chinese company has been selling cars with sodium based...

Very nice- looks like a lot of fun. The script in the video suggests the factory is in southern India.

The same sort of plastic used for soda bottles. The carbon dioxide takes a long time to diffuse through the plastic. Any "pores" are much smaller than bacteria and spores. It sometimes is, but it doesn't need to be because it is packed sterile. The mayo I buy has an inner seal that protects...

As I'm discussing your post #49, I'm not going to talk about commercially produced food is produced using knowledge of microbiology and chemistry in the USA. It is safe until it is opened. Like I said, botulism poisoning is the most infamous poisoning. None-the less, your statement "Bacteria...
