First off they'll be too expensive for poor people to afford. That's one lawsuit. Secondly very few areas will have hydrogen refueling stations at that time so these vehicles will primarily be sold in CA. Very unfair, another lawsuit. If you own any stock in Honda Motors it might be time to start dumping it. The whole purpose of the plugin concept is to be able to charge it during offpeak hours ( generally at night as the owner sleeps ). Really, that's the "whole" purpose. So I guess reducing oil consumption and transitioning to domestically produced forms of energy serves no purpose. If that's the case then the current hybrids on the market serve no purpose. I agree that charging off the grid at night would be preferrable to charging off the grid during the day. The utilities will control this with pricing and load management switches. There's even trials going on of V2G (vehicle to grid) systems where PHEVs plugged in during the day could be used as a source of backup power for the utilities. In this system the utilities would pay for any power drawn from the cars battery pack and subsidize vehicles that participated in this program. On top of that there's the possibility of charging during the day off solar power. Try refueling an ICE with solar power.

"And a series hybrid definitely has an advantage over the ICE because an ICE does not allow for recapturing energy through regenerative braking. I don't think you can regenerate gasoline." I think there were some early attempts to use a flywheel to capture the kinetic energy for use when starting up the ICE-only vehicles, but I don't think it panned out. I assume you are referring to "ICE only" because the HSD does recapture part of the energy.

The Prius has a battery pack that costs around $3,000, weighs 100 lbs, can provide maybe 2 miles of all electric driving and allows this vehicle to achieve about 25% better mileage than a Corolla. For a lot of Prius owners that represents the battery technology being "there" for this application. There definitely are battery packs that exist today that will provide for the 40 mile all electric goal that Chevy is striving for. The main questions are. How much will they cost? How long will they last? How much will they weigh? And what are the answers to these questions that represents the technology being there. For me this battery pack would have to cost less than $8k, last 10 years/150k miles, and weigh no more than 300 lbs. There are currently battery manufacturers claiming to be able to meet the cost and weight criteria. The longevity question won't be answered until these battery packs have actually been in service for this amount of time. Maybe they will last that long but we can't know for sure until they actually do. My reference to improved battery technology was meant to convey that no matter how good battery technology may be today it is reasonable to assume that it will continue to get better in the future.

Replying to: kdhspyder (Nov 27, 2007 8:01 am) What was your argument against Toyota when the following was announced? Were you the driving force that got Toyota to shelve the Plug-in Prius? Toyota's revelation Tuesday that it will develop a new "plug-in hybrid" - which uses a wall socket at night to charge and relies on an electric motor to go many miles before sipping any gasoline - could presage a major shift in automotive technology, some industry analysts say. Toyota itself had steadfastly denied any interest in plug-in technology. A senior Toyota engineer told the Monitor early last year the company had little interest. But gasoline prices have since soared to more than $3 a gallon. On Tuesday, the president of Toyota's North American subsidiary, Jim Press, said the company is looking at developing a plug-in vehicle that can "travel greater distances without using its gas engine." The technology would "conserve more oil and slice smog and greenhouse gases to nearly imperceptible levels". http://www.csmonitor.com/2006/0720/p02s01-ussc.html This is only for the privileged few! Or is this only Toyota vapor ware? Ultra-Green: Radical 100-MPG Toyota Prius in the Works for 2009 Due in two years as a 2009 model, the next Prius is set to be an evolution, company sources say. The hybrid will retain the same basic 1.5-liter hybrid drivetrain. But Toyota is now on a mission to do two things: drive the economy ratings skyward, and cut the associated costs by 20-30 percent. http://www.edmunds.com/insideline/do/News/articleId=109981

Replying to: tpe (Nov 27, 2007 3:35 pm) Yup, I agree, and I was expressing my opinion - the technology isn't there yet. |
