Tiles are great, I'd love to have a roof last 100 years. But they don't get as much use here because of issues with ice damning up the bottom edge and pooling water up under the tile, which then freezes and expands and dislodges or damags the tile. That can be overcome, but it's easier and cheaper to use shingles.
Shoot, the page is gone. I really wanted to see the AP article addressing this very important issue, lol.
Oh, agreed!
The benefits increase as the efficiency of the car increases though, check out Aptera. They say they get 10 miles per kwh, and they have a lot of surface area for panels. Enough that in ideal conditions they say they get 40 miles per day from solar. It is a bit different looking though.
I looked up prices in Massachusetts, they are higher than the national average. Looks like 2 main factors:
1 A higher than usual percentage of mini splits vs central air. These will be more efficient and have a lot of comfort benefits, but are considerably pricier then retrofitting a central air system. So if you are retro fitting CA, you could come in under average.
2 MAs impressive $10k+ incentive system for whole home heat pump systems has resulted in HVAC companies raising prices, because of course it has. This is why we can't have nice things.
In addition to Thejevans points, your cost estimate is very high. That cost would be in line for a geothermal heat pump, which is far more efficient. Air to air heat pumps can be installed for more like $3-10k in most residential homes. And on the higher end that is a big house that is probably saving more than $550 a year.

I am not any kind of expert either, but I have been following this company for a couple of years. If it makes it to market and is at all price competitive i can't see it not being a big deal. Granted, that is an if, not when, but they seem to be further along than most battery tech you read about.
No rare earth metals or even nickel or copper, has a very flat degradation curve even at charge rates up to 30C (testing stopped at 3k cycles in the coin cell tests), non flammable and non toxic. The only thing you would wish for is better capacity, but it is already better than any mass produced Li ion cell, and it has a theoretical maximum a couple times that of Li ions.
A increasing percentage of new construction gets heat pumps. Some replacement HVAC units make the switch, but there is still a large portion of people who won't because of misinformation and/or stubbornness.
But, unfortunately, most existing residential systems do not use heat pumps, under 20% in the US I believe.
And sentencing should be simple. However many years of life their decisions knowingly stole from their victims should the absolute minimum sentence. And of course every Pound they were paid since the first incident. Adjusted for inflation and with interest.
I believe they are kei cars. I looked up the safety ratings on them when I heard about them, and the D.O.T. equivalent board that rated them gave them 5 stars. But it could be that was a kei car specific rating. It did show diagrams with front and side air bags, and all the electronic crash avoidance systems. It's bigger and seems like it would be safer than a smart car. I honestly think the hold up is that if we had options like that in the US fewer bigger, more expensive, cars would be sold. Maybe not a lot fewer, but enough fewer that it is overall more profitable not to offer them.
Looks like there is a 1000V variant. I'm guessing there just aren't any chargers built with it yet.
North American Charging Standard Technical Specification 6. Ratings 6.1 Voltage Rating The North American Charging Standard exists in both a 500V rated configuration and a 1,000V rated configuration. The 1,000V version is mechanically backwards compatible (i.e. 500V inlets can mate with 1,000V connectors and 500V connectors can mate with 1,000V inlets)

I was talking about efficiency and range, which typically falls pretty short of cars intended to be EVs. But there are also other changes like wheels being closer to the front ends of the vehicles and not needing the transmission hump in the floor, giving more passenger and cargo space.
All new cars are terrible for privacy, EV or not. Small shops doing conversions on older cars will absolutely be better in that regard. But as soon as you make it a mass market thing, the same incentives to invade the privacy of their consumers will end up with the same result. Better privacy and data protection laws are the only way to stop that, I think.
