Electric Cars ... one day

I just couldn't resist posting this usual, Elon Musk managed to fool those who were only focusing on the headline numbers, which were both good and bad: while TSLA missed earnings, reporting a (non-GAAP) 4Q loss per share of $1.33, or $215 million, far worse than the consensus estimate loss of $0.82. On a GAAP basis, the company reported a loss of $330 million, or $2.04 per share, compared with a loss of $283 million or $2.13 a share in the year-earlier quarter. This amount to a loss of over $13,000 for each of the 25,051 cars delivered in the quarter.

As I've said many times before if it worked it would be working already (oh, but I fogot about the conspiracy theories)

As I've also said, if we want to use electricity to power vehicles we need to change the paradigm entirely. Stop making them as heavy as vehicles are today (because the power needed is related to the weight, turns out Newton is still right) and start making urban environments that don't need cars to simply get you from where you live to where you work / shop.

I know people can't grasp numbers, but hopefully those don't read my blog (or if they do then just accept that this is right).

From this Tesla source:

What will the battery size be for the base model that provides <= 215 miles of range? A 70D is 240 miles, and a 70 is 230 miles. A 60 was about 210. Since the 3 is 20% smaller, does that imply it would get about 20% more range for a given battery size, or is it non-linear? 
Seems like they should be able to pull off 215 miles with a 50kWh battery on Model 3.
If you think about that number and what it means, I used a total of 800kWh in my whole house for the entire quater which was winter (in Australia so not super cold).

So to drive for a week (or in reality probably less) a Tesla will use about what I need for my house (fridge, freezer, hotwater, lights ...) in the same period. Oh and that assumes charging is 100% efficient (which it isn't) and you don't tear off at the lights or drive in hilly areas.

Get a grip folks ... where the hell is that energy coming from and how will you get it there?

If you want to be green and sustainable - ride an electric bicycle or better yet pedal the thing and get some exersize too.

Stop paying to be serviced by a service industry which sees you like the way Pastoralists use the term service.
