Hey just while we're on this theme, can we spare a thought for the often-maligned mining companies? Without their efforts none of this would be possible.

Brilliant basil. 👏

Dead on the money.

Depends on your circumstances. An elderly couple who do 95%of their running around town and had the foresight to install solar panels in 2017 must be sitting pretty.


Some outfits offer a 7 year battery replacement. By then they probably will not be able to drive by law anyway.


Different strokes...

Hmmmmm quite so.

Do you recall the good old days when ICE was king and the cry was 'Put a Tiger in your Tank'


That Tiger still exists in those tanks, only it has morphed into a gas not a liquid....

Sounds suspiciously like an updated extension of LPG.... but the energy output is linked to a charger to a battery in turn combined with electric motors to a final drive.

Nup!

Hmmmmm again..... but a good link nevertheless

Back in the 1980's I decided to build an electric car. (battery powered)

I had picked up an aircraft starter/generator rate at 9KW. @9000rpm.

I had a Renault 12TL car that had front wheel drive with the engine mounted north/south in front of the gearbox. I was able to mount the starter/generator above and to the side of the gearbox and duplex chain drive to the gearbox input, 2 to 1 reduction. That gave me a similar rpm to the old engine.

No clutch but retained the 4 speed gearbox to provide a reverse . Another aircraft generator, 4KW, driven by a 5HP Briggs and Stratton tucked in the engine compartment to charge the 4/12volt 100AH batteries located in the…

I do have that book. The Pogue carburetor was another interesting device described in the book.

Thanks for sharing.


So long as countries to use fossil fuel to create electricity for the grid, and which is used to charge EVs, EVs are fossil fuel powered. To argue anything else is living a lie. In NZ we have a high percentage of renewable electricity generation (in the form of hydro), compared to Australia and the USA. However since our hydro generation is essentially static, any increased electricity demand is being met by fossil fuel.


So long as that situation exists, EVs will never have a lower carbon footprint than ICE (Internal Combustion Engine) cars.


Estimates as to how many kms an EV must drive before the carbon footprint reaches zero, varies from 30,000km to 300,000km, depending…

Yes, they work very well, but do require a good flow to be practical. I have installed two of them. One to supply water and the other that provided 24 volts through a smart charger to a battery bank. 15 amps was usual current flow until battery float level was achieved. had a few problems with moisture affecting the alternator. Solved that with an AC generator that was fully sealed. Super reliable, but only 10 amps maximum current output. Did the job, that was the important thing.
