Hybrid Diesels

What is a CR 56 CC?

Detailed study from a national government lab (Sandia I think, I gave links in other thread) were performed that show the opposite for hybrid cars.

But you do allow me to make the point that one should not build a new diesel for their boat, but recycle an existing hybrid drivetrain from a wrecked prius for example, which would more green-eee-err.

Which would produce more green house gasses over its lifetime? A simple diesel or a complicated hybrid system..... I don't know... studies have shown at standard gasoline cars produce less pollution over its lifetime than hybrids...

There are a few other considerations that might tip the balance in favour of a series hybrid on a sailboat.
Suppose that you actually mostly sail your boat (and not motor 75% of the time as most boats do) and us the motor mostly to generate electricity.
Then it makes sense to optimise your prime engine for just that, and install a electric motor for propulsion. That would make even more sense if you went all electric on your boat and you would end up with only a single fuel you would need to store.
So the system could use something like this:
M12 Series | Polar Power

Or all diesel for that matter.

Anyways, let us consider a cruising sailboat. I doubt strongly that anybody would like to go with serial hybrid in that case. Some points to support that:
1. In adverse conditions you would like to have all the power you can get. Many cruisers upgrade their boats with at least 30% more power then needed to get to the hull speed.
2. Series hybrid is essentially less economical then direct drive (or parallel hybrid) diesel. Some power is always lost in mechanical - electrical - mechanical energy conversion.
3. Serial hybrid has less redundancy then parallel hybrid. You have only one (electrical) motor to relay on.

Thanks Don.

The Garbone:

That looked awesome! More people might take
a look at it if you give a hint what it is.

It's essentially an internal combustion engine
that translates its power into electricity
immediately, stripped down to the bare
necessities. Looks quite promising.

The video is short and well worth watching.

People are forgetting about the radioactive waste by-products from mining neodymium for magnets in electric motors and generators. You end up better off having a nuclear reactor in your boat. Big Wind’s Dirty Little Secret: Toxic Lakes and Radioactive Waste - IER

Hmm. A think thank linked to the oil industry. Surely an unbiassed source :-)

You correct. I should have put in a blurb about the link. Hopefully they catch on and in ten years or so I can repower to electric hybrid using one.

Less moving parts, looks simple to maintain. 40 hp is pretty good.

Did they mention the Athabasca Tar Sands?

Actually, diesel/electric submarines were adapted from WW1 German submarines and the emerging locomotive industry in the 30s and 40s, not the other way around. However, the rest of your post is accurate.

Why go with the "hybrid" system? What benefit are you hoping to derive other than being able to say you have one? More complexity = more chances for stuff to f-up.

The first being designed as a power plant to run sans snorkel to greater depths.

The second being designed to put immediate power to the wheels.

Neither are needed on my boat unless I am sinking.
