Rusdy,
Do you have any idea how much YOU are giving to the fossil fuel industry?
That's why I strongly recommend "I'd rather see the 'subsidy' in fossil fuel industry re-allocated to the renewable energy industry. "

Re: EV subsidies - When will Australia learn?

hypothetically speaking, if EV subsidy in the form of AUD5k per car, and end users gobbled it up enthusiastically, let say, 500k of 'em (half of annual car sales in land of Oz), that will be 2.5 BILLION AUD in that year alone...

Re: How DC chargers work

Agreed, especially if there was a DC fast charger network worth speaking of around here.

Re: Grounding shielding around motor cable

I'm still confused with 'ground loops'. I thought 'ground loops' only happens when there is a poor ground connection (or long distance wiring). So, when current induces on the cable shield, it will in turn induce current to signal wire. So, if you have good ground (such as car or bike's frame), then...
