tesla roadster - may stop production

Starting at $250k AUD we take off 1/11th as GST or $22,727. Then we take off the 33% luxury car tax, which is on every dollar over $75k for a fuel efficient vehicle. or $75,807. And at this point we note that the government gets a whopping $98,535 not including on road costs. So that leaves us with ...

A pack of Teslas!

None of them were ever assembled in china. There were some battery packs that were assembled in asia, but no cars. All the cars have always rolled off the lotus assembly line in england as 'gliders' then flown to the states where they had their drivetrains installed. Here is one of the photos from t...

A pack of Teslas!

Sounds to me like poor reporting. The Roadster isn't made by Lotus, for a start. It's built in China, and assembled in the USA. They're going to build the S in the USA, and I presume also the Roadster. Which might explain the lack of a 2010 model Roadster. As it said in that report, they're shoppin...

200km @ 100kph ute, possible?

if you can get the ABS to work, the only way regen will cause problems is if the regen braking exceeds tyre grip. otherwise the ABS will reduce friction braking down to 0 if need be to maintain traction. Matt ABS is more like an on/off switch that runs duty cycles. So it wont give you control down ...

If you're serious about rust prevention you should use the tannic acid based rust converters. The phosphoric acid ones slow down the process but dont stop it.

How to convert a hybrid

* The transaxle is lighter in weight and reduces torque losses by as much as 20 percent compared to the previous model. Seriously guys, if it was possible to reduce the transaxle loss by 20%, what was it before and what actually is it now ? (personally I doubt this number). What's 20% of 10% losses...

Y'see that was the reason for my question, in that the term possibly didn't describe the actuality.

If it's AC, does that imply that the current changes polarity? If that's what it implies, does that actually happen?

ABB motor and VFD selection

On a side note, the 11kV 1.3MW (not a typo) VFD at work broke yesterday. It's been two days with all the gurus looking at it and we're still down. It broke without warning, suspected thunderstorm activity though. And yeah, it's an ABB. It's also almost 1 of a kind.

This is the mess you get into when all the currencies available are faith based.

Johny:
There are no taxation implications without a realised capital gain, and you can't measure a capital gain in batteries. So ensure that you spend all your gains.

Awesome posts James. A simple accelerometer can achieve 90% of what you just mentioned combined with some appropriate algorithms. Steering angle is not required, as you're only looking at forces. thus you only need to compensate for forces as they happen. So a simple 3 axis accelerometer can do it a...

No. That's not debatable. Anyone who teaches uppercase "K" for *1000 is simply wrong. This stuff is all written down in an international standard ISO_31 , the corresponding Australian Standard refers to that. Yes it is unfortunate that the lowercase "k" for kilo is an exception to the "uppercase fo...
