I like that word. That and alliteration.

Don't like the Spanish word "leche" (milk).

Back on the electric car thing, a massive increase in charge to weight ratio and charge to volume ratio would make it viable to solve the charging time issue. Car battery packs could then be small and light enough to make it practical to change them at a battery station. Drive in, swap for a charged pack, the discharged pack from your car can be charged in the battery station, so it doesn't matter if it takes a few hours.

It would also improve handling, performance and efficiency by quite a bit.

Shame it doesn't exist. But it might at some point, maybe within a decade.

Although that still leaves all the other problems.

The grid could be upgraded enough, at a staggering cost.

Increasing generating capacity by enough would take more than just money.

Maybe it will be viable in decades to come.

Your postulations are mind boggling (I meant NUMBING).... no matter what you cannot build a safe vehicle in this manner, and no I do not feel the need to elaborate further, its all in your "research" materials.

Without any evidence that it's hugely better than traditional turbine designs, it's just more Tesla hype.

The basic design is well known. It's not like it's a secret. So why isn't everyone using it instead of other turbine designs? I think it's because it's worse than other turbine designs.

I know that many of the Space Shuttle's pumps are 'finless' (the re-invention I mentioned) and that in theory they could be as small as a marble & still put out lots of pressure.
They work, it's just a matter of them not self-destructing.

Sorry Angilion! I read an article about how a Japanese company is using Tesla's ideas to make hyper-efficient fans for industrial use, but that was several years ago and of course I can't find it.
His main problem was metalurgy. The rotor deformed under the enormous stress and set it off-balance. Other than that it was tested and proven, but not practical in 1923.

5Cats...can you find any hard figures for the *total* efficiency of a *working* Tesla turbine? Note the emphasised words.

It's an interesting turbine design but, as is usually the case with anything Tesla is connected with, a myriad implausible claims are made for it. It's easy to build a small one, but far harder to scale it up to a commercial size. I think it's worth noting that Tesla never managed to do so.

It isn't the solution many people think it is. Not yet, anyway. We need far more of everything - batteries from plentiful materials at a fraction of the price, batteries with a much higher charge to weight and mass ratios, at least several times as much electricty generating capacity, much more carrying capacity on the national grid...and even then the charge time is still a problem unless someone finds a way to safely feed hundreds of KW from the grid to the car, somehow.

Assume everyone went electric anyway, despite the far higher cost.

We can't make enough batteries to meet the demand.

We can't make enough electricty to meet the demand.

We can't distribute enough electricity to meet the demand.

We can't charge the cars fast enough to make it viable except for overnight charge in a garage. Many people don't have a garage.

That's not just a matter of the batteries being able to charge fast enough. It's also a matter of supplying the charge. If, for example, you want to charge 50KWh in 5 minutes (i.e. as a reasonable fuel station stop), you need to supply 600KW to the car and even that's with 100% efficiency. Can't be done.

A comparison of the Tesla and the Lotus Elise it's based on. S is base model, SC is top end. Both handle much better than Tesla due to lower weight.

UK prices, feel free to do the same for your own country.

If anyone disagrees about the tax...do you really think the government would stop all that tax income? Of course not.

2010 Elise S 37.2 mpg
SC 28 mpg

Petrol 111.89 per litre
Tax 72.85p
Actual price = 39.04p

UK gallon = 4.55 litres

UK gallon actual price 177.63

UK cost per mile:

Elise S 4.78
Elise SC 6.34

UK electricity cost ~10p per Kwh

Tesla 28Kwh per 100 miles.

UK cost per mile: 2.8p

But...the big cost is battery replacement. Tesla say you'll get 100,000 miles of normal driving. They won't give a price, because they know it's bad news. £10,000 is a reasonable estimate. So that adds 10p per mile, making it double the running cost of an Elise SC and not far off triple that of the Elise S, both of which are much better cars at half the

I sat in the tesla at the Seattle car show, nice little car. I cant remember the name of it but another company made a purely electric sedan.

But if they allowed this out, our economy would collapse *maybe*, who wants to live in a future with a different economy when you can live in a barren waist land....our kids have soooo much to look forward to!!

vv Tesla invented A/C current, you might have heard of it?
This place has along, dry reading of his works.
The device I'm refering to is this:
Which was 'rediscovered' at great expense in the 90's, lolz! They thought they hit the jackpot, but Tesla pattented it almost a century before!
ANyhow, On-topic: Yes, early versions of the electric car would have cost $200K and wouldn't be as good as...

>>Nicola Tesla invented

Yeah! And the warp drive, and anti-gravity, and the computer, and the portals gun, and the stargate, and the time machine, and parallel universes, and the laser, and the tractor beam, and the atom bomb, and R2D2! WHY doesn't he get credit for any of this? Why oh why were all of his secret inventions suppressed by the government ?
