More than half of the US population lives in coastal watersheds or floodplains. http://www.floods.org/ace-files/documentlibrary/National_Policy/FEMA_Fugate_Testimony_NFIP_6-9-11.pdf The federal flood insurance program was amended in 2004 to reduce repetitive losses (the "two floods and you're...

Agree, this has the makings of an Allison event.

I thought Prius had completely shifted to lithium, but they have not. The Prius 2 is lithium. There are about 300 million vehicles in the US. According to your site, more than 4 million are hybrids. According to the NFPA, there about 170,000 vehicle fires each year, so if the rates were the...

European canals (lots of 10 kpg speed limits) and the US great loop. I have spoken to Calder.

I note that the Expectations vs. Reality thread currently running is largely about noise and how to reduce it.

While early hybrids used NiMH, and some still do, the big six, including Tesla models, Chevy Volt and Bolt, Prius and Leaf, which together dwarf other electric car producers combined, are all lithium. And electric cars (either pure or hybrid) are catching on fire at a much lower rate than...

Tried to read about CPPs. Over my head.

I, too, want a large LiFePO4 bank for house loads. How to charge? One way is with an independent diesel generator. Another way is with a big generator hung off the propulsion engine. Well, once you do that, you're 95% of the way to electric propulsion. The cost difference between an...

I believe Steyr has stopped offering its hybrid system. Too many problems, not enough market, I don't know. But Greenline is doing the same thing, using Volvo engines. They seem to have sold quite a few boats.

I guess the fact that nobody wants a boat like that explains why nobody builds a boat like that. (With that single exception; wasn't me) Here's another poll to run: does any body want a boat that sinks after 100 hours? Builders definitely want to know, if there's a market, prices can be reduced.

No generator, by the way. The engine-motor combination does that, so one bit of complexity eliminated.

So how big a problem is hour-after-hour, day-after-day low-speed operation of diesel engines (glazing, etc.)? There seems to be much concern about this, but lots of boats seem to do it. I still need decent sized engines for coastal cruising.

Why? The enemy of electric motors is heat, not load (recognizing that greater load = greater heat). The Volt motors are water cooled. Is the cooling adequate for higher sustained loads? I don't know, but I would bet it is.

Sigh. The speed limit in thousands of miles of canals is dead slow. People riding their bikes on the tow paths are moving faster than the boats. Some joggers are. I understand the dollars and cents. Having air conditioning on the boat reduces efficiency, but I won't be without it. I...

Not sure I understand what you're saying. Greenline boat has twin diesels, so there are two 7 kw chargers. Example: Start in morning on diesels. Batteries discharged. Cruise for two hours on diesel. Batteries now fully charged. Cruise four hours on batteries. Batteries now discharged...

Aren't the satellite domes receive only?

Most people don't do sustained highway operation in their cars, and some (many) don't do sustained highway operation in their boats. I have no idea how many boats there are cruising on the European canals, but it is not a small number. Electric would be great on the Trent-Severn, but diesel is...

See Chevy Volt. Day-to-day around town, fully electric (Gen 2 of the Volt will go 50+ miles on battery). But need to go on a road trip, no problem, gas engine (I get 37 mpg on the gas engine).

To do the European canals, there are some feisty rivers that must be dealt with, and some coastal cruising, and I have the US great loop in mind, as well, so traditional diesel power is essential.

Perhaps I'm biased by my Volt experience. In 5-1/2 years and more than 100,000 miles, I have spent 0 (zero) on repairs. It has been in the shop once, warranty. I've changed the oil four times, and some tires. That's it. As far as I know, a Prius is dependable, and there are loads of them...

Lifestyle features, that's right. But then you went back to the usual strawman arguments. Nobody serious is suggesting cruising at 20 knots with electric propulsion. And while solar is nice, and relatively cheap, it's not key. A Greenline 40', for instance, can be equipped with two 7kw...

Maybe diesel, maybe propane, who knows. Hard to get LiFePO4 batteries to explode.
