Each lithium-ion cell has a potential of 2.7-4.23volts depending on state of charge; currently cell size is limited by application.
We would need a lot more in the way of specs for this battery pack to evaluate it absent bench testing.
I just bought a Ryobi 12V rated battery operated drill with two batteries, a sophisticated charger and a carrying bag from Home Depot for $79.95.
After about 20 minutes of heavy duty screw turning the battery is still strong and holding a charge - unlike Ni-cad batteries which forced me to retire my old Kawasaki 19.2v drill that never ran 20 minutes doing anything.
It took 45 minutes each to charge the partially charged batteries per instructions and when the second battery was fully charged the charger went to a steady green indicator light which remains brightly on since 6/8/08.
I couldn’t be more satisfied at this point except for the “more-power” syndrome.
I’ve seen topers put away hair tonic, mouthwash and Sterno but I never saw one brave enough to chug transmission fluid.
I don’t need a diesel fueled vehicle at this time.
Nor do I need an electric vehicle.
Should I need either, I will go to proven sources.
I will not swoon over a guy who converts cars in his spare time.
When he produces something innovative, I’ll give him some credit.
Haven’t seen anything yet.
I actually can’t figure out why he got in the news at all.
It was rhetorical.
By asking, I was telling.
Sorry, Barry.
“It’s kind of funny how a group that appeals to conservatives can have such techno-intolerance.”
Techno-skepticism, not intolerance. When people start making claims which seem to flout the known laws of thermodynamics, we get skeptical. When people start talking about using relatively large gas turbine engines to provide bursts of power for charging batteries or capacitors, I know I’m skeptical.
Slick.

“The Lincoln’s new electric engine will power the car and when it begins to lose juice, Young will simply flip a switch and the car will run on biodiesel fuel until the electric motor is recharged. “A 19-foot-long car, the longest car ever made at its time. Two and half tons, the heaviest car at its time,” Young said, “And it can get 100 miles to the gallon, not 10 miles to the gallon.””
Doesn’t sound like it will get 100mpg to me. Sounds like it will get about what it would get if you just put a diesel engine in it. And why would you have to flip a switch?
“”It’s not cost-effective for someone to run out and spend $40,000 to double the fuel economy, but I have no shortage of customers,” Goodwin says.”
You don’t say...
No kiddin’ Johnny.
“Goodwin, 37, drives a 1987 gas burning Wagoneer, rents his home and will sheepishly tell you he didn’t graduate from high school.”
I can tell he didn’t make it through high school...
“Goodwin’s developing a download that can be installed in a car’s computer and improve the mileage by five to seven mpg without losing performance. He expects it to cost about $200.”
Uh huh... Well you know what they say about one being born every minute.
Hey, I hope these conversions are okay with CARB. They’re touchy about modifying things in Cali...
Ummm, check your tagline.
Took me a while to find the article, I for the life of me couldn’t remember the name of the company -
http://www.sae.org/technical/papers/970292
I don’t care how precise it is, at that size and weight we could mass produce them if we wanted to.
I was looking for the name of this company and for the life of me couldn’t remember it, took a while to google it:
http://query.nytimes.com/gst/fullpage.html?res=9A06E0DA163DF931A35751C1A961958260
Take a look at this little baby, with its size and weight we could easily mass produce it if we wanted to, even with the tolerances in the microns.
At 29% efficient, why would we want to mass produce them?
Thats thermal efficiency, compared to a standard diesel or gas engine that is quite high if memory serves.
oops, looks like you're right on that number. From the SAE writeup perhaps that is high efficiency for that type of engine, I was thinking of another thermal number in the upper teens, have to look for the chart I had earlier.
I was looking at that chart too. This unit is coupled with a generator on the same shaft to charge batteries in one enclosed unit, so all of the loss is in the unit itself and not like the diagram which would represent the efficiency of the electric motors.
Still, as fuel prices rise it is thinking like this that can make a big difference down the road, the more people tinker with this stuff eventually we will hit on groundbreaking advances.
The Capstone turbine generator concept has been around for over ten years. Look at the date of the article you pointed to.
It never seems to have gone anywhere besides fishing for investors. I suspect a standard diesel genset is not only cheaper, but more efficient in real life.
That picture you posted is very informative and helps to make a valid argument as to why Mr. Goodwin is blowing smoke. What has he come up with that is solving any of the losses inherent in a motor vehicle?
Nothing. He should put down the wrenches and go into sales / marketing. Perhaps he already has.

60 miles per gallon of diesel, using /two/ secondary sources of energy - the battery packs as well as the hydrogen, both of which aren’t properly accounted for, and even then, it’s a ‘guesstimate’ that he gets anywhere near that fuel economy.
Not to mention that water vapor is a greenhouse gas. Wonder how long hydrogen power will last once the greenies realize that...
