Re: electric lawn mower

I have found that the 12 inch bar on some of those cheap Black & Decker and Ryobi 230 volt AC chain saws actually fit/replace the 6 inch bar on the battery pole saws.

Sulfur is how a chemist spells sulphur because English is a stupid language and no one agrees on anything (especially stubborn Americans)

Oh well, Every Lab I worked in it was either Sulphur or Schwefel. And this is the ABC not the NBC, a bit said.

What is Sulfur? Is it Sulphur?

Perhaps the next step would be Aluminium Sulphur batteries?

Re: Grounding shielding around motor cable

I think Rudsy at lower frequencies this is still the case, but these days we are using higher frequency AC, digitally clipping it producing harmonics and actually producing RF radiation as distinct from just induction problems.

Re: 9 Nissan Leafs for auction at Pickles: 8 NSW, 1 ACT

Well when all 640 of the first crop of Leafs suffer battery failures and nobody can be arsed stumping up $10k to replace it, there will be 640 Leaf motors for EV conversions available for cheap. The strange thing is, how much is the battery for the conversion going to cost?, how much work is involv...

Re: 3 phase outlet, what is suitable for EV charging?

I used 230 V because that's the international standard, and even most parts of Australia will be converting to 230 V nominal in the next year or two. I'll believe it when I see it; mains here is still often well over 240 V (244.6 right now, as measured by my solar energy system; 248 and higher is n...

Re: 3 phase outlet, what is suitable for EV charging?

So, that would be the circuit to supply one or more 3 phase EV chargers? I never did get my head around how 3 phase converted to watts, 22kW appears to be the biggest expected demand, 22 kW is 32 A per phase (230 x 3 x 32 = 22,080). And 240 volts X 1.732 (square root of 3 (phases) ) = 415 volts
