Re: Will it.....
"Technically planes are a form of vehicle, last year an electric plane circumnavigated the world, try that in your yank tank."
Not really a valid comparison is it?
Since we're talking about ground vehicles, let's consider which of an electric car or standard SUV might be best for that same trip - personally I'd be choosing the SUV (or even better, a proper 4WD) - ideally one with a turbo-charged engine for those higher parts of the trip and diesel for better availability of fuel.
Current electric vehicles seem to be a fairly practical solution for commuter trips, but once you get beyond the range of a single battery charge the time to recharge becomes an important part of the viability equation - will your customers be happy to be billed for having your staff sitting around, even for an hour, waiting for a battery to recharge, or will they prefer you to use quick-fill dead dinosaur type fuels?
A practical non-commuter EV needs to have the battery capacity to see it through a full working (or family travel) day so that recharging can take place during non-billable or resting hours.
'Yes dear, I know the kids are tired and sun-burnt and want to be in bed, and yes, I know that you're tired too and that everything's full of sand from our day at the beach, but it's ok, we should get our turn at the charging station in about 6 hours and a couple of hours after that we should just about have enough juice in the battery be able to make it home, so long as I don't exceed 40km/h.'
Sorry, but much as I like the idea of an electric vehicle that's not a conversation I want to have anytime soon - and owning two vehicles to do the work of one is not a concept that's going to fly with me either.
