[ExI] gas prices

[Henry Rivera]


Your ideas in this area, Spike, remind me of this image which was circulating around Facebook:



It generated lots of debate. Bottom line stated well here: https://climatefeedback.org/claimreview/connecting-a-generator-to-the-wheel-of-an-electric-vehicle-wont-recharge-its-battery/

Pic below of a fossil fuel-powered generator. 110v plugs at maybe 12 amps take forever to charge my Tesla battery relatively speaking: around 3 miles gained for every hour of charging vs about 220 mi/hr at a Supercharger. A 220v diesel generator at 30 amps would give me about 18 mi/hr I think.

The amount of energy that would provide in that 75 minutes would carry the Tesla driver about… 30 miles, 40 if she drives 55.

Lithium batteries degrade with age as well as charge cycles, so… if you don’t go on cross country trips often, the battery trailer is a no-go anyway, never mind the voided warranty.

I am back to looking at a more modest rig like the Nissan leaf, an older kinda junky one that won’t cost much.  Their resale price drops dramatically after they are 6 or 7 years old, because the range and performance start to degrade noticeably.  But if one is hauling a generator, that wouldn’t matter as much.
