Sorry, Jason, while you do make some good points about the state of
things now, or in the past, things are changing rapidly, likely
faster than they did when the diesel wave hit passenger cars a few
decades ago. And it's regional. Having an infrastructure with an
outlet for every parking spot already exists in the Frozen North,
for example. EVs are eminently practical for a lot of folks, and
not so for a lot of others. As Bob pointed out, there is no
one-size that fits all. Never has been, never will. But to call an
EV a novelty is hyperbole, and does a disservice to the discussion.<br>
<br>
To the discussion (please) - digital communications from EVs -
Nick's point is the important one. We don't have real data on the
state of EV drive trains with respect to digital RF communication.
And it's important to note that every Hybrid from the Prius forward
can have one or both drive trains running at any particular time, so
gathering real data is a multidimensional challenge.<br>
<br>
One point that has not been made, focusing on the group's intended
topic, is that the digital communication discussed here is
predominantly VHF and above, strong signal (vs weak), and
predominantly FM-based. None of these are particularly susceptible
to the sorts of RFI generated by any of the drive trains (EV or
suck-squeeze-bang-blow, as one journalist describes an ICE). It
certainly has not been a problem in any of my current or past cars,
of either variety. I do grant that working weak signal low-band HF
from an EV in motion is more likely to have interference trouble
than perhaps other cars (my AM radio can attest to that), but it's
not the problem we're trying to understand or solve here. It's also
arguably less important these days, as digital systems such as
WinLink have been used very effectively in disaster situations
(recent California fires, for example).<br>

<div>You misspelled "very few people". Cmon Bob, you're an
engineer, do the math. A quick glance out my window shows
about 100 parking places. to equip each one with a "$15
Home Depot outlet" would require something like 50
weatherproof outdoor receptacles and 1500 amps of
capacity. I guarantee your $15 each "estimate" is off by
at least an order of magnitude, probably 2.</div>

<div>If a solar footprint that size could actually provide a
useful amount of power to the vehicle, why the heck would
you put it on the GROUND and not on the VEHICLE???</div>
<div><br>
</div>
<div>PEVs are only a partial solution to the transportation
needs for many, and I suspect of those many the vast
majority are like me and cannot afford to have a PEV daily
driver _and_ an ICE to do the rest of the work, so we
stick with the single vehicle that solves all the
transportation problems.</div>
<div><br>
</div>
<div>Once solar and storage advance to the point where an EV
can be a daily driver without plugging in, have a 500 mile
range on battery, and have an infrastructure for charging
that's either as ubiquitous as parking or as fast as
pumping 20 gallons of gas, then they'll become generally
useful. Until then they're a novelty.</div>
<div><br>
</div>
<div>Hybrids are shown to have the highest TCO, which should
be obvious to anyone who thinks about it for more than
0.37 seconds - you have 2 complete systems to feed and
care for, not just one.</div>
<div><br>
</div>
<div>And if the greenies every stopped repeating the CO2
mantra and actually looked at the total environmental
impact of EVs - rare earth mining, battery disposal, etc -
they'd be a lot less excited about them.</div>
