I know, but he'll find a way to somehow screw it up so it is a flop or horribly unreliable.

I'm just an angry guy, sometimes

I'm guessing oil company connections have a lot to do with how much bio is to be mixed with diesel in order to keep engines under warranty. Just a hunch though.

I know that there are still some emissions when using it, but it is greatly reduced.

Using biodiesel mainly reduces net CO2 emissions and to some extent HC and PM, but not enough and not as much as the latest injection & emission technology, and it does nothing to reduce NOx. The new diesels can't use more than 5% bio because bio has different volatility and burns differently and that could screw up the regeneration process of the particulate filter. The answer to these problems is 2nd generation (synthetic) biofuels. Since they are chemically pure and can be custom-made, they should be fully compatible with any emission or injection equipment.

Diesel-electric hybrid systems have been around for a long time......used in ships, submarines and trains since before WWII. The battery technology has held it up from being scaled down for practical automotive use. And now that battery technology has made more inroads in the last 5 years than it had in the past 80 years. The most efficient use of electrical energy is to use it at its point of generation..........in the vehicle as it is generated by the hybrid system......not after it is generated and transmitted through high voltage lines as DC current and then converted to AC for use at your wall outlet.........then converted back to DC to charge your car batteries.
I look forward to more Diesel or diesel/electric vehicles in the future if it happens

this is something I always wondered. do trains have huge battery packs? It seems like since they run at a pretty much continuous speed they dont really need the batteries, they could run straight from the properly sized diesel generators. In a car the challenge to match load to generation is solved with the batteries as the buffer to take out the ups and downs of the load requirements. If you ran motors directly from the genset with a constantly varying load all kinds of bad things happen. To me it seems even though the technology is similar in component parts, the challenge is quite a bit different than just a downsizing. its more of an expansion of the technology to compensate for the different application. I feel that any battery dependant technology will be doomed in the end. Once all the priuses or is prii are 5 years old and the batteries start hitting the yards I wonder which will be the bigger environmental hit. The manufacture of these batteries is also a dirty business, I think GM chose to make the Volt batteries offshore. My guess is that part of that decision is driven by the future laws that will come if we trey to make batteries domestically at that scale. I guess we will see what we see. I think the oil companies made a big mistake getting all of the creative people in the US motivated to find something new. I consider this our generations moon shot, people will surprise us all with creative ways to keep from paying exorbitant prices and giving them record profits
