10% loss was just meant for quick calc, and I did not even factor in the loss in power generation etc.
And the assumption was only 50% of the capacity, so that would drop to ~150 miles. Again, it's claimed value, how much you can actually get out of it really varies.
If you just want to get 30 miles per day, then you will need ~ 6A, which is within household circuit rating but will still double the load of the ordinary family peak.
Please don't simply use Watts to calculate AC load, it will not give you the real current demand.
- leoedin 5y agoUsing 10% for a quick calc is fine, if you only use it once. But you then multiplied that error by 3. The resulting assumption - that the transmission losses with 3 transformers would be ~73% (0.9^3) is completely wrong, given that we know total grid transmission losses are in the order of <10%
- LargoLasskhyfv 5y agoThey aren't...
- mrjin 5y agoWell, look at your calc again. Transmission loss per my calc is actually 1 - 0.9^3 = 27.1%. At grid level, high efficient part(mainly stable industry loads) will cover up low efficiency of household loads.
