The problem lends itself to a temperature gradient solution. For "flow" to occur we need a temperature differential between the two environments. While it is clear that low level heat is available in the atmosphere for conversion to energy of another variety the problem remains with exactly where the low energy state is to be found. If within the rotating machine there is a zone of infinite negative pressure or lower temp the "flow" will be unidirectional. A perfect perpetual motion machine. In this case there is also a component of "exhaust" that is sub normal in it's heat energy value. This would cause the flow to be around the "outside" of the machine. The reason is simple. If you extract some heat energy from a volume of air it will loose volume causing a pressure differential against the higher energy surroundings. thus the machine is actually doing better than unity with an amount of electrical energy to spare. Shirley it would be easier to spin the pump in the air conditioner backwards and then have it produce rather than consume energy. P.S If there is still a swag of silly money chasing this project I retract everything I said and would of course make myself available for a senior consultancy.

Does anyone know of a good source for hot, low impedance, distributorless coils? They're not much different from standard coils, except for having two spark plugs in series on each side of the secondary windings. I'm also interested in a four-channel capacitive discharge driver for the coils, such as MSD's DSI-4, only with more current handling capability. I think the MSD is a bit limited, and cannot drive the really hot coils, just like their old 6AL box. As far as I can tell, the only coil packs currently available are the factory units from Ford and Chevy. I've been told that they suffer from insulation breakdown on the secondary side, if you try and drive them very hard. I'm looking for the waste-spark equivalent of the Crane PS-92, or MSD pro-power. I want lightning bolts :) I'm putting together an EFI setup for a BBC using the Speed-Pro ECU. I don't want to spend good money buying old technology (distributor), and I need an ignition system. I've checked with the big three, MSD, Crane, and Jacobs. Jacobs claims to have prototypes, but thats about it. Any ideas? - -- -Clay ------------------------------ End of DIY_EFI Digest V4 #522 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
