Re: HP in EV vs HP in ICE

There may be some rules developed about how long the vehicle should run for. I can’t imagine an EV full of super caps that runs at well over the 2400hp of the V8, but can only accelerate for 10 seconds before needing a recharge would be considered in the spirit of the competition. At this stage I d...

Re: Zero Turn Mower Conversion

21HP (15kW) obviously is not used continuously in reality. Otherwise for an hour mow you would use 15kWh of battery capacity. That's a modest $7,500 battery pack... It maybe easier to work out how much petrol you use for a mow and try to convert that into a battery capacity. This would also give you...

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

...hole in the roof or the opposite wall... Well I guess that matches the rest of the quality of the structure. So there is what like $10k of electronic stuff on a rough concrete bench and a hole in the wall. They tripled the value of the building. I'm guessing old school style laundry / wash house.

That's dedication overlaying the two. So they DO match up bar the box not in the wide shot which is not relevant to the fire. There are a number of other things I notice now about the fire.

Re: Seeking opinions on independent Twin motors with different gearing

I had a look around for some pics of the L710 AWD running gear but haven't found anything yet. Must be rare if I can't even get a picture of one.

Re: Seeking opinions on independent Twin motors with different gearing

Sorry I don't see what benefit you would get stuffing around with AWD. If you take 1st gear ratio + diff and add about 20% ie if was a turbo etc then using that torque direct drive you end up with around 200kW. So as if you were stuck in 1st gear with a turbo but still goes up to 150kph+ Estimated i...

The difference now is that GST is collected from the supplier overseas. Under $1,000 customs still don't look at it. IF GST...

Re: Numberplate ID for EV and Hydrogen Vehicles

The usual first action is to disconnect the engine battery and in most cases that cuts off the petrol/diesel/LPG/HV battery, so I'm guessing hydrogen fuel vehicles would follow the same safety protocol.
