Is this Hybrid Hummer the Real Thing?
by Dan
Ca I hook up a gas or diesel generator directly to the a ac or dc motor, insted of the usual batter/charged system? I am a photog and I know that one of my flashes uses a battery cluster and once charged the AC adapter can be plugged into the flash and will bypass the batteries that have charged the capacitor and then run directly on AC power for the most part. I would like to know if there is a way to do the same using a (once charged), battery/capacitor and (bypass) with AC directly. Can the generator be running all the time, and will it be enough power to directly power the car? I heard that the Army has done something of the same, in which a HumVee uses a diesel power generator to power the vehicle and then (when needed) can run silent for a short time, then turn back on the generator and keep on going (without the need to stop and charge) before continuing on the down the road. Hi, Dan - You're talking about the hybrid Hummer? Yeah, I heard about it. It's got batteries, though. Were you thinking of ditching the batteries altogether, or just charging them on the fly? If you were thinking about losing the batteries, the problem is that while a big enough generator will supply plenty of power to run your electric motor, the generator is designed to run at a constant speed. Is it possible to have a variable-speed generator powering an electric motor? I don't see why not in theory, although I don't know anybody who's doing it. Check out the video up there, though...it seems like these folks are doing something like it, but still with batteries. Even the Chevy Volt went with batteries in their series hybrid, and they wouldn't have if there was any way around it. Batteries are too heavy to take on board lightly. (Sorry about that; ) Now, a battery/capacitor combination? That's actually in the works, I understand. I heard Zenn and Eestor are hooking up to build an electric car with batteries for the main job of powering the car, and an ultracapacitor for the heavy lifting. It's not here yet, so we'll see how that goes. All the best with your project, and keep us posted! Regards, Lynne Click here to read or post comments.
