Excellent! Thank you for the help. Three thousand farads at 2.7 volts! Except that it's 2.7 volts for only a fraction of a second. :-( I think that super/ultra caps have been used in experimental liquid fuel only quasi-hybrids. IIRC EVDLer Jeff Major was involved with at least one such trial, and he might have some comments if he's tuned in. Solectria also used supercaps experimentally as current levelers in EVs, in an effort to get more range out of lead batteries. They worked, but the rapid voltage fall of capacitors meant they needed a DC:DC converter, and its (in)efficiency was a problem. Also, the range improvement was very dependent on how the vehicle was driven. http://www.evdl.org/docs/supercap_leveler.pdf David Roden - Akron, Ohio, USA EVDL Administrator = = = = = = = = = = = = = = = = = = = = = = = = = = = = = EVDL Information: http://www.evdl.org/help/ = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Note: mail sent to "evpost" and "etpost" addresses will not reach me.
