Weird as heck plugs look like mini clothes dryer plugs.
Single split phase is standard in US homes. Practically all homes should have access to 240v by utilizing both "hot" legs.

The number of wires required for 120v and 240v are the same. You get 240v by connecting what would be the neutral wire on a 120v circuit to the other hot leg. You only need an extra wire if you want both 120v and 240v available on the same outlet (even then you only need 3 wires because you could use a hot and ground for 120v, but that wouldn't be as safe or meet code).



I had a high power 120v AC unit that would blow the standard 15A breaker constantly. There was an unused 240v 20A outlet nearby that I converted to 120v by replacing the 240v 20A breaker with a 120v 20A. It simply connects one of the wires to neutral (ground) instead of the other hot leg.



This is why I'm doubting ProDigit's lack of 240v access. As long as there is sufficient room in the breaker panel, there should be access to 240v. There is even a way to get 240v using a Y extension cord connected to two 120v outlets that are on opposite electrical legs. They come premade, or some people make their own.



There are plenty of reasons not to buy an expensive EV, but lack of 240v access is rarely a big problem because adding 240v is relatively easy, and 120v is often sufficient.

I'm 100% with you on this. There are a surprising number of rich kids with McLarens or Audi R8s (and at least two Ferrari 488 GTOs) in this college town who use the cars for nothing more than to commute back and forth to school from their ugly high-rise apartments that have sprung up like weeds in the past 5 years--essentially functioning as economy cars. Meanwhile, the fastest driver in the local autocross club races his bone-stock Mazda3 sedan.

However, I can appreciate that for most people, a car is "defined," essentially, by its looks. Big wheels, thin tires, and a fastback = sports car. Tallback, small wheels, frumpy = economy car. And never the twain shall meet.

I've plastered my Prius with decals, including the Watkins Glen short course outline, now that it's officially a race car and has driven further on a track than all the European exotics in this town combined. And I happily tell people that when they ask.

I was honestly curious how James defined those 2 categories, as there are some fairly blurred lines. We can certainly call a Ferrari a sports car, but then there are sporty/luxury cars like my TSX. It has fairly firm suspension and remains flatter in a corner than most sedans, but it isn't particularly fast to accelerate despite the close-ratio 6-speed transmission. It has a higher end interior with many amenities, but might not be considered luxury either.

The Model 3 is reported to be hitting 0-60 in 3.3 seconds, which is in sports car territory. Heck, I'm not sure my sports bike does better. Is it a sports car? Does appearance define the category more than performance? If so, what defines it. If performance determines the category, then what is that criteria?

The two sets of vehicles that fall on one side or the other of the 1302 Superbeetle.

Thanks for asking.

As to heating taking less power than A/C. I don't have to do the calculations, I have an EV. Heating takes roughly 3x more power than running the A/C even at 90-100F. Take a look at my fuel log. Those giant dips in the winter are from running the heat. My car has heated seats but those don't defrost / defog the windshield.
You need at least 2 phases for that to work.
With a single phase, it won't work.

My father ran power to a previously wired garage by making up a 50ft extension cord with two male ends. It seemed to work. [shrug]

It works in every house I've owned. An electrician converted two 120v single phase circuits in my electrical panel to one 240v circuit for my newly installed heat pump.

3 Phase Power vs Single Phase Power € OEM Panels

"Dual Phase or Split Phase power is also Single Phase because it’s a two wire Alternating Current (AC ) power circuit. In the US, this is the standard household power arrangement with two (Phase A, Phase B) 120V power wires (180 degrees out of phase with one another) and one neutral wire."

Some rooms are wired with top electrical outlets being fed by 1 circuit, and the bottom outlets fed by another, though it isn't all that common.

You can use extension cords with the Y adapter.

Some blurring of lines: the classic datsun 210 in stock form is an econobox, in ralley form is considered a racing sport car.

Look at the whole mg midget line.

I suspect acceleration is not a definition, but handling is, further defined by suspension stiffness, body roll, and cornering.

Last place I worked at has a tendency to lose a phase. We would then string extension cords all over to connect the remaining phases to power the 220v servers.

Voip/ cloud service is stupid if there is no backup system
