Just brainstorming a bit here trying to figure if I can come up with my own hybrid drive for an 8ton displacement Cat. Starting with a marinized VW TDI motor that puts out quite a bit of torque and HP, and using that to power an EMRAX electric AC PM motor, configured as a generator. Then get a proper controller for the EMRAX that can throw a bunch of DC at a pair of the 12kw Thunderstruck kits, one in each hull. I would also use the normal car alternator to power the boats systems while underway. I will have small LTO battery bank that can also run the Thunderstrucks for short distances when I am closer to shore, etc. When living on the hook the smallish Solar and LTO batteries can be configured to run as a 12v or 24v system to run the boats systems.
I like the idea of using VW diesel because they are fairly available and I think the parts are out there to convert one for marine use. There are no shortage of mechanics that can work on one, worldwide. The TDI can be set to run at its max HP/Torque for the EMRAX's best performance. It is good to run these engines at a steady RPM.
This will be a fairly expensive setup in time, $$ and complexity but I think it should just work once setup. I like the Thunderstruck kits as the final drive. Those kits seem pretty good. The LTO batteries are fast charging, safe and are good for 10000 cycles without losing capacity, have a 30yr shelf life, aren't subject to temperature limits like some batteries.
The main issue I think is sizing the EMRAX motor, getting all the various cooling systems layed out and defined, and marinizing that VW engine...
Anything else?
Thanks
