[img src=" " alt=" "] I suspect you're saying it's happened before and that jumping to GW conclusion is an unfounded leap. Could be you're right in this instance. There's certainly a mountain of hype around the subject. But the evidence supports that some effects are real and should not be denied.

... They (particularly China) are controlled economies and can dictate more. ... Like it was rampant capitalism and the free market that resulted in ethanol in every tank?

So after I get my all electric F-150 I need to worry about where I can plug it in?
I think that I will invent the some kind of invisible decharger/charger that I can slide under a nearby fully charged vehicle to borrow electriciy. An electric version of a siphon hose. I can start a crowd funding site for R&D.

There is the other side of the ev problem. We are getting close to the first round of the waste battery apocalypse. Britain is already declaring it an emergency. What do you do with 10s of thousands of spent ev batteries. They don’t last forever and are filled with dangerous things that need to be handled correctly.

I don't know that I ever purchased gas for my old Yamaha 100 trail bike or 125 Enduro while I was in high school. I think it all came from siphoning it out of my parents' cars, trucks and tractors.

I have to think that down the road (pun very much intended) the solution to electric vehicles will be some type of new technology that will increase capacity and decrease size, weight, and other issues currently associated with today's battery technology. It's hard for me to imagine that we could get where we want to go the way things are now.

IMHO the best right now is a small gas motor on-board to charge the battery. You don't need a 440 Six-pack, just more like a lawnmower motor that burns a gallon or less an hour to run a generator and keep charging the batteries. The Toyota system, I think it is that uses the breaks to charge the battery only works if you use the breaks. OK in city driving but useless long distance.

The Toyota system, I think it is that uses the breaks to charge the battery only works if you use the breaks. OK in city driving but useless long distance. The Chevy Volt is a series hybrid, similar to this in that the engine charges the battery only and the car runs on electric only (as opposed to the prius which is a parallel hybrid, where the electric assists). In the case of the Volt though, they went for full on being able to drive off of the electric generated by the engine. While that gives greater (basically unlimited mileage) it kind of defeats the purpose.
I've always envisioned a small turbine (highly efficient) that would run when the car wasn't moving, to charge the batteries. Let's face it, outside of really long trips, most cars spend 8 - 16 hours a day, just sitting. During that time a charging system would only need to provide 1/8 to 1/16 the power used per day to charge the vehicle. For a 80kwh battery, the charger would only have to be in the range of 5 - 10kw you can get all day runtime on a couple of gallons of gas, or a small hydrogen hydride tank (which spews water out, no CO2)

Thank you for reporting my error. I frequently turn my mind off when posting to The Soundhole.

That's an inherent flaw in battery power. You lose charge when it's cold. When I worked at Ford in the 90s, the company offered employees a lease deal on electric Rangers including all the charging apparatus for your garage, etc. At that time the range of those trucks was about 90 miles. Still potentially a decent work commuter deal. But this was Detroit. And I lived about 20 miles from work, 40 mile round trip. And in January that 30-40% range reduction could put you pretty close to not making it home at night. Don't think the whole thing was immensely popular overall and like GMs original EVs, it quickly tanked. It didn't help that one Christmas we had temperatures that dropped to 40 below. Took out the battery in my Taurus overnight and I had to scramble to get a jump to get to work in the morning. And that was with a gas engine that once started, ran all day. Electric cars just won't get seriously popular outside of southern California and other warm climes until the laws of physics change. And that probably won't be anytime soon.

Do they defeat their purpose?

Not really. Diesel electrics don't have any batteries. There are a lot of reasons why trains (and some ships) run diesel-electric systems. One of the biggies is the ability of electric motors to generate full torque at zero RPM. But its really about economics, and it mostly comes down to the "electric transmissions" on diesel-electrics being way, way simpler and cheaper than an equivalent mechanical transmission.

Jeff, can you sketch out "electric transmissions" for us -- is it just shifting voltage or something instead of shiting gears? I've never thought how diesel locomotives actually work, beyond the basic power system.
