    EV Thread

    A pair of cringe-worthy videos proving how bad an idea EVs are:





    The entire purpose of a car is to have the sort of freedom you don't have when relying on public transportation. It makes me thankful for the 5 minutes I spend every couple weeks at a gas pump, cleaning my rear window while dinosaur remains flow into my fuel tank.

    A 300-plus mile route, eh?

    A Passat or Touareg TDI could do it non-stop.

    Twice.

    While keeping the occupants in air-conditioned comfort.

    I can see using such a car for commuting and grocery-getting. But for real road trips? NFW!
    The engineering problems are likely insurmountable. It would be like proposing to land a rocket booster section on a barge floating in the middle of the ocean.

    ...and now we have come full circle, with my argument that an EV is fine 96% of the time for most people. When you want to take a road trip, hitch up a fuel-powered generator, rent a fuel-powered car, or maybe come up with some type of front/rear railroad coupler arrangement so that you can join a highway train and recharge/regen while someone else is towing you and a batch of other cars.

    Another option for interstate highways is some sort of a "third rail" setup in the dedicated EV lane. It doesn't need to be a continuous run along the entire length of the road. I'm thinking that 15-30 mile segments with a 50-75 mile gap between them would allow someone to quick charge when needed while still making miles and not stopping. I really like the German metro railroad idea of using a super-capacitor on their locomotives in lieu of a battery pack, and having the train recharge at every statin platform in the time that it takes passengers to board/unboard.

    Funny story - Just this morning, I gave serious thought to plunking down a grand to get on Tesla's Model 3 order books for the end of 2018. (FWIW, all of the federal tax incentives for the Model 3 will be gone by then.) The deal-breaker was that Tesla does not have an available AM radio receiver as an option in any vehicle that they make. What were they thinking?????

    vreihen: Easy fix - All you need is a coil, a diode and a very rudimentary amplifier (I assume that no one sells "crystal sets" any more up there) - think of the saving that you just made for the planet!!

    The fuel-powered generator is the only one of these that's appealing to my sensibilities. I've said this for many years -- the charging port should centrally located on the rear of the car to allow for this. I'd happily buy a 25kW towable diesel gen set, 'cause it would make an excellent home backup as well when it's not powering the car on road trips.

    I'm gonna go full tinfoil here: I guess Elon doesn't want people listening to "talk radio".

    It's true the Venn diagram of EV owners and AM radio listeners probably have little overlap.

    But if I were a betting man, I'd say there may be intractable electromagnetic interference problems. Think alternator noise, except with a Ludicrous Mode capable pair of motor-generators.

    I made one for the radio merit badge back in my boy scout days, and could easily wind another coil for a tuner. They wanted us to make a rock setting and use a raw piece of germanium and figure out which way the bias was, but I took the easier route and used a pre-packaged glass diode instead.

    Anyway, the real reason why it is a deal-breaker is that leaving out the AM radio makes me think that the drivetrain is an unshielded RF nightmare on MF, HF, and the lower VHF bands. I would hate to be stuck with a commuter car where 10 and 6 meter radio frequencies were useless, since the transceiver on the dashboard of the Mighty Dodge always has one of its dual tuners set to 29.620 in case the sunspots align for a decent 10-meter band opening to South America or Europe.

    Oh, and if I was worried about saving the planet, I wouldn't be driving around in an oversized 3,500kg (4 ton) diesel pickup truck every day. If you want to see my carbon footprint, look at the accelerator pedal.....

    Why not convert gas stations to battery stations :-)

    Load and unload the batteries under the car, from a massive underground storage area.

    You pay a fee for the swap, the receive a battery that you never have to replace - the fee covers the "lease" of the battery, and the charge.

    All it would take, is for a standard to be setup that manufacturers and countries around the world comply with.....

    Oh yeah.

    Forget it!

    ^^^ I call that idea the barbecue grill propane tank business model. There's a store on every street corner here with an outdoor display of refilled propane tanks. Bring in an empty tank, and exchange it for a full tank and $15 or so.

    You joke about the lack of battery pack standards, but didn't take into account that these are not kid's toys with easily-swappable AA batteries. By the time you disconnect the cooling lines, swap the batteries, and bleed the system, the car that came in at the same time and was simply plugged in next to it would be fully charged and ready to go.

    Tow-behind rental generators, hydrogen fuel cells, or a third rail power system along roads are the only way to make an EV viable for a road trip.....

    I was thinking that movie theaters would be an ideal spot for chargers. You have people who will not leave their parking spots for 2 hours. Require proof of movie ticket purchase (fandango/chargepoint tie-in?) and you could entice viewers to unwatchable movies by offering free charging. Buy two $11 tickets for the emoji movie and we will give you $1.50 of electricity for free!
