@ Stefan:

Thanks for posting this.  I have that exact same van with a bad transmission that I have been holding onto to convert to electric.  I want to pull the engine and trans and dump in a motor, batteries, supercaps and a small gas powered generator.
(Like used on construction sites or motorhomes)  I almost got rid of it but watching this made me decide to keep it for my "some time in the future" experiments.

Daren Luedtke (inventor) has found a company (Luedtke Enterprises): see: www.leiglobal.com/cm/index.php.

I apologize for my first post to be a negative one, but I must post the question. "why do we need this?"
Of all the electric vehicles I have seen, *some in person* they all run mainly in 2nd gear and you only use the electric motor when you need to. This is a clear violation of the KISS rule, and I do not see a need for it. Please set me straight if I have some how completely missed the point.

@ Pese:

You are right, I just tried it and it is.....gone!  He probably is now going for a patent and his attorney told him he can't get one if he has already disclosed this info to the public.  So, he went back to erase any disclosure evidence.  If I am correct, this won't work as it is too late.  You can't unring a bell. Just my thoughts.

Sorry, but not all is true what you said.
Daren Luedtke has already two very similar patents for his EV's. US 727959 and WO 2007047352.
On his homepage you can download a video which don't shows the engine but the car in motion.

To all: It seems to me that it is necessary to do detailed research before writing something.

Sorry I made a mistake:

The first number is wrong (727959) the right number is (727958). This number is the application number (60/727,958). Date: 18. Ocotber 2005, International application number: PCT/US2006/039864).

Good advice, you should take it yourself.  "Sorry I made a mistake: " (quote from Alan)

I said " He probably is now going for a patent....."
"If I am correct....."l
"Just my thoughts"

I didn't say anything was certain.  These were "just my thoughts".  You need to read more closely prior to posting.

Hi Bill,

I think we shouldn't argue about words.
Fact is: Daren get granted his patents. Something is going on.
He shows that there are different ways to propel a vehicle. Good luck to him and hope to hear from him soon.

What is a d-bag?
Please let us discuss about inventions!!!!!!!!!

d-bag, see http://en.wikipedia.org/wiki/Douche (http://en.wikipedia.org/wiki/Douche)


Ok so maybe I spoke too soon, but seeing the video for what it was, I saw an electric motor running all the time from batteries, connected to a completely unnecessary device that was connected to the drive train.
 
Ev's run like this, the energy goes from the batteries, to the motor, through a clutch, to the drive train....simple KISS rule.
 
Electric motors have full torque at low RPM's so there is not need for a variable speed transition of any kind.


 
http://www.leiglobal.com/index_files/PEVS_In_Motion.wmv  I think I can run faster than that van, but I give him an E for effort.
 
I do think he had a good idea for the wind generation project, but the whole EV thing I just do not understand.
 

To learn more about this project, please visit planetevs.com or email info@planetevs.com.
 
Odd how that site plantevs.com doesn't exist anymore...even Google had a bad cash of it on may 18th 2008.

After reading his patent at http://www.freepatentsonline.com/y2007/0105672.html (http://www.freepatentsonline.com/y2007/0105672.html)

With his design you will still need batteries and motor, a clutch, a DC to DC convertor, a motor controller, a pot, and you still have to power all your heated seats, mirrors, fans, heaters, A/C, exc.

Now if this in some way is more efficient that a solid state computerized system, than I may be proven wrong, and I may have to have a chat with the company that is looking at converting my car to an EV, due to be completed by next spring, pending road trials of the new AC drive system in the car of the guy that got there before me.
