Hi back, yes, the self discharge rate is a problem. It is the main reason I am opting for Li instead of cheaper Pb batteries.I don't mind going slow in a Model A (people smile and wave- try that in a sports car). and I had the car.(I also have a Honda Inight but mounting something in that little space would be lots of machining and would limitwhat I could use off the shelf and it has all that crazy inter connected electronics on everything) I will live the big fancy stuff to LENR-CARS http://www.lenr-cars.com/ It is fairly cool here (I am at 9000 ft) and I will have to keep the garage warm to keep the self discharge rate within reason. If it drops below 0 the discharge rate goes way up for Li. typical self discharge rates for common rechargeable cells are as follows:
Lead Acid 4% to 6% per month Nickel Cadmium 15% to 20% per month Nickel Metal Hydride 30% per month Lithium 2% to 3% per month Also that is the reason why I expect a very long charging time for just a short fun ride. It is all just for fun. D2 PS - realize the system is to be used to charge the car batteries should also stand alone. I hope for 10 W net but I can make it workat around 2W... just barely but I can. Also the time horizon for that project is about a year. I hope for a simple LED light system by ICCF in the summer as my first stepping stone but the other takes slow work and long lead time. PPS I am around 0.25W thermal now but the problem is the conversion. When you run the numbers you have to get a much larger sample to make most conversion approaches work with existing off the shelf items. So..... 10-20 mW net to an LED and then >2 W for a charging of a car or something with even modest usage. I just don't see how Rossi and Defkalion can do what they claim but they are just after low COP and heat. I wish them luck. > From: [email protected] > To: [email protected] > Subject: Re: [Vo]:Crowd Funding LENR > Date: Fri, 1 Mar 2013 06:39:29 +1100 > > In reply to DJ Cravens's message of Wed, 27 Feb 2013 21:27:01 -0700: > Hi D2, > [snip] > > > >read the info.
