Tesla Too Hot to Handle?

image

The owner of the Tesla S that caught fire last week (video below) probably doesn't need to go to traffic school or back to driving school- but he maybe could use some financial advice.

Most of the online commentary has fretted about the Tesla's batteries - that maybe they are an accident waiting to happen. Not likely. This is the first case of a Tesla going up in smoke - and the batteries it uses are not fundamentally different from the batteries that have been in use in other-brand electric (and hybrid-electric) cars for many years. The hot-selling Toyota Prius, for example, hasn't given anyone the hot foot yet - and it's been on the market for a decade, with hundreds of thousands of them sold.

The Prius - and all other current hybrids (and electric cars) use either nickel metal hydride (NiMH) or lithium-ion batteries. So does the Tesla. They're no more dangerous - as such - than driving around with 15 gallons of highly volatile gasoline sloshing around underneath you. So long as the batteries - and the gasoline tank - are designed properly (and not handled irresponsibly) the risk of a fire is pretty low.

That wasn't the case with Ford's hot battery.

Back in the '90s, Ford built an experimental electric vehicle called the Ecostar. It had a sodium-sulfur battery that had to be maintained at several hundred degrees for proper operation - and to prevent it from becoming a mobile Chernobyl.

Luckily, it was just an experiment.

A failed one.

Now, this Tesla.

I just don't get it. Maybe you do - and can explain it to me.

It costs $70,000 - to start. Yes, I know. It is luxurious. But isn't that kind of beside the point? I thought electric cars were - chiefly - about saving people money. Giving them a way to get around paying through the nose for gas. But if they're paying through the nose for the car... ?

Well, you tell me.

Ah, but it is very quick. True. But only briefly. If you run the Tesla 0-06 at full tilt more than a couple of times - or drive it over 70 MPH for any length of time on the highway - the batteries will also deplete quickly. Then, you're stuck waiting while the car recharges - which takes at least 45 minutes to an hour, if you have access to a special high-voltage charging station. If not, it'll be hours.

Maybe overnight.

So, you've got a really quick car you're more or less forced to drive like a Geo Metro. And you paid $70,000 for it. Maybe you can explain it to me... .

The way I see it, if a person wanted to save money on driving, he'd buy a Prius - and put the $50,000 he just saved (vs. the Tesla) toward gassing it up...

For the next 50 years.

But hey, what do I know... . END
