BYD sells a lot of electric cars in Europe so they must meet some reasonable set of safety standards. Pretty sure they have been outselling Tesla for the last year or so for whatever that means. They are a more basic and less expensive auto so that just might be what the consumers need.
True, but a little perspective... BYD is often cited on the BEV fanboi sites as being ground breakers in solid state batteries (didn't Cudes say that they are already operating 750 mile ranges all over China or something like that?), and battery tech in general. So it's worth clarifying that these are NOT solid state battery cars or even some kind of super tightly packed, 350Wh/kg lithium ion, either. They are what you say the are: more basic and less expensive.Quote:

For energy density, think of it like regular density. Regular density like you learn in primary school, (or do Americans learn it in secondary school?), is mass over volume. So energy density properly understood and used, would be something like Wh/cubic meter or cubic centimetre or such.
Armed with the his knowledge, when you read from sources that misuse or misunderstand energy density and confuse it with specific energy, you should approach everything else you learn from that site with a critical eye.

Sure Cudes, mate. The more the merrier. :) One of the biggest issues in the BEV movement, is ignorance fueled by hype. The more people who know enough to see through the hype and share a little grounding, the more realistic our expectations for battery boating will be.Quote:

Photovoltaic solar provides like 6% of the world's electrical power, so who cares? If the panels degraded at 100% per year, the only people who would notice are the dumb bastards that bought them.Quote:

No it doesn't. It means the real powerplants are being throttled back by 6% during the sunny days to allow the subsidized solar power to be used.Quote:

And only for the amount of taxes you paid over 5 years or up to 30% of the system cost. It's your money. It doesn't actually come from other peoples taxes. It's like a business writes of business expenses to reduce their tax burden. You write off your solar system from your taxes. I got my system a long time ago. It has been great! I produce plenty more than i use. No money down and my bill went down 20% from what it was. Plus, with electric prices soaring, mine will not change.

You could just say, "Sorry, I was wrong"... rather than deflect from the conversation.Quote:
