> So electric cars have electric heaters; I had not thought about that aspect before. That would be a considerable inefficiency;

To some extent. The main problem is that it flattens the battery more quickly and impacts range in winter time, the actual cost of the heater for an hour or two is generally relatively trivial compared to the other costs of running the car.

The newer electric cars have much less of an issue though. Instead of using electric heaters they run the air conditioner in reverse (it's an 'air source heat pump' in fact) and most of the heat energy then comes from the external environment rather than resistive heating. The heat pump uses about 1/3 of the power.

Nope, even the worst case is not a deal breaker for most people.

The thing is, most people don't empty the battery most days. A lot of people do like 20 miles a day, so in practice, even with a conventional socket, the car is full again each morning; even on 110 volts.

If you have a 240 volt socket, which are very, very widely available, it's even less of an issue.

And the extra cost to install a higher current charging point is very low. Where I live most premises have a 30 amp, 240 volt circuit already for their electric cookers. That's about 6kW, and the Nissan Leaf has a 24kWh battery; it can do an 80% charge in about 4 hours.

In most cases crypto is like having the worlds best lock on your door; the people that want to get in just jimmy the window instead.

The phone thing could certainly happen in theory, but in practice the NSA may have already installed a backdoor or found an accidental backdoor that was due to a bug. And they would probably copy the flashdrive in the phone and analyse it later, possibly on a supercomputer if they're really keen; a lot of commercial crypto is deliberately weak so they can crack it that way if they really have to.

A charge station at home is just a wall socket- you can literally just plug your car into the wall and charge it already.

So EVERY house that is on the grid is already EV infrastructure.

The numbers show that the existing grid can (with some exceptions) handle EV charging (which would and should be mostly at night where the grid is underutilised anyway.)

Actually, the electricity can come from renewables.

Some places have hydroelectricity, nuff said.

Also, wind power and solar is available nearly everywhere, and electric cars do great on that; they don't normally need to charge up everyday, and when there's a glut of wind or solar they can suck it down; and (if you have the right equipment) even sell it back again.

It has been claimed that Michael Hastings might have been assassinated by hacking his car:

I'm not sure whether he actually died that way, but it's theoretically possible, if you've pissed sufficiently rich and powerful people off enough, and he may have done.

Nothing is finished until the paperwork is done.
