At 800 watts for 1/2 gph, it's not very energy efficient.
You could do better than that with a 125 amp alternator and your main engine just a click above idle. The quiet part is really nice though. Jeff wrote: Yes, I checked it out at Newport last week. Very slick. But the Bang for the Buck is a bit lacking - its $12K and doesn't put out enough to run a coffeemaker. On the other hand, its a neat trickle charger, and would be a good match for a lightweight boat that uses outboards instead of diesels (like a catamaran).

The concept behind it is you run it longer than a Genset and it is quite enough that it is not annoying. Look at it like its a battery charger and a heater. From the perspective it works better than a genset. And you don't need as big a battery bank. Viewed as an alternative to a bigger battery bank & bigger charger to keep that bank up, it's a sensible concept. But it's still *very* expensive; you could buy a small diesel genset and built a soundproof enclosure yourself. If these guys are actually making money, we should go into that business! DSK |
