Most of my Chevy Volt''s 75,000 miles were on electricity. Interesting that even in Germany, where people are given company cars more frequently, and where the more people live in apartments (where finding a lug can be difficult, still 44% of Toyota miles are electric. That would seem to mean...

This is the weirdest thread I've seen in quite a while. I'm finding it pretty repulsive. Given that it does not appear that Shmoe is willing to do even the simplest math, here is a project for anyone who actually cares, and is not here just to be a prick. Let's round the likely...

They are neither claiming nor demonstrating 4.17 volts as a nominal voltage. Read the report. Find the right figure. You are clueless or lying re the size of the module; you are clueless or lying re the volumetric energy density. Show the math or I can only conclude that you a belligerent...

Show the fricking math. Show their claim for volumetric energy density and show that the pack is too small. (Do you think that the pack is the size of its representation oon your computer screen?? It's not. ) I have very high tolerance for people who do not understand math or...

If you are going to make outrageously extraordinary claims, then you need to, at very least, show your math. What figure are you using for volumetric energy density and what dimensions are you using for the pack. Without your showing the math, It is impossible to discern WTF you re trying to...

I realized this is ambiguous. I was intending to say: 1. There is nothing unusual about motors of 90% - 95% efficiency (or even 97% in larger motors). Those numbers are not hard to find throughout industry. 2. There is nothing outside that range (on the high side**) in the Donut motor...

This is nonsensical. Does not parse. Charging at 5kW? Discharging at 5kW? That's less 10 hp, which a pretty small pack can feed.

There seem to be many very literal-minded and gullible people contributing to this thread, so it is worth pointing out, explicitly, that you are being sarcastic. Stanley Meyers' "water powered" car, the many HHO offerings, Dennis Lee's several perpetual motion frauds, etc, etc, all played off...

Of course. I was being facetious. VTT is well-known in much of the world by battery engineers, most automotive engineers, etc. In the US, the Sloan Automotive Lab at MIT comes to mind as being similar, although it has been more focused on combustion... (something we hope does not happen...

We must be talking about different companies. Donut Lab is famous for making funny looking rear wheels for motorcycles that look like a donut... big hole in the middle. I have the paper specs for one of their motors (of a somewhat different size), and they look perfectly fine, and are more...

Consider this: People were nearly as skeptical about the LFP cells I used on that little car 15 years ago... especially re their bursting into flames. I still have them, and they came from some-fly-by night company in China (CATL or some crap like that). Half of them still have their little...

It's fun to imagine that it does, but that is not the case in real life. The Insight is far more efficient at moving one or two people and some luggage, if you are thinking about resource consumption and generation of CO2. I am something of a "nut" about such things, so when my wife...

I am also skeptical, but have been in Marko's position on a far smaller scale. His slightly early original announcement, (originally a quarter away from delivery) gives him the ability to gauge whether he can sell the bikes: they are three times the price of a Honda 600, that performs about...

Of course, a dealer can ask any price he feels he can get away with, just as anyone does when selling a house. Only a fool would pay more than 40K for a new Bronco in 2022. That "MSRP" is fiction I assume, at about double what I paid for my 2025 Lightning.... which according to Jim Farley, is...

To continue my rant: Who are you up against in negotiating a vehicle price, direct vs dealer: 1: A huge corporation with multi-million dollar ad budget, and billion dollar losses they are trying to recoup and hundreds of lawyers on staff... or 2: some poor shmoe who has to sell cars to keep...

If MSRP is 30,000, only a fool would pay more than 27,000, no matter what the dealer is trying to sell you. Among numerous other vehicles, I've owned a Saturn and a Tesla. Paid full hit retail (MSRP) for both, because of manufacturer price control. Both were substantially overpriced...

Heck No!!! I would not want to insult Donut Lab like that.

The intentional shadiness of staying dark, only revealing partial information. Accusing everyone else of being the problem because "we're the real deal". I didn't get that impression from his presentation. He seemed to outline the way things have gone, with the expected skepticism, but he...

Nor is this very confidence inspiring: " South African native Elon Musk, who claims he is a Cultural Christian, built Zip 2, a city guide that solved some problem and reportedly made him a millionaire. This despite having no education beyond the bachelor's level. "

You are probably wrong about the "trusting" part. I've participated in putting a couple frauds out of business; I didn't believe in Santa Claus at any age beyond 3, and don't believe the religious myths that people use to comfort themselves and to feel superior to the "others" who have equally...
