Diy hybrid
Many years ago I heard of UPS trucks experimenting with a hydraulic regenerative system, where upon braking the hydraulic pump on the engine would engage and pump pressurized fluid into a high pressure reservoir, so after stopping the truck can you use the accumulated hydraulic pressure to help launch the truck. I recall it actually works fairly decent I don't know why they never implemented it. It's basically hydraulic version of a hybrid drive, and one could do it with a compressor and an air tank and an air pump.
I know some of you guys like to pulse and glide, and I've been thinking about it that instead of removing the alternator, if you were to install an actual generator, you could have the best of all worlds where you could get one or two horsepower out of an alternator generator to increase your coast downtown and distance. Some of the old vehicles on the road at generators, I even had a long tracktor that used the same generator to start the engine which then turned into a generator after starting. What's old it will be you again, and this could prove reliable enough.
Mercedes has such a system on one of their cars, a small lead acid battery with just a few horsepower to eight in acceleration, just enough so they can call it a hybrid but it really is not. But the way you guys drive and is efficient as your cars are, it actually might work out quite well
