Can anyone recommend a diesel generator similar to the DC WhisperGen
below for home use but one that generates a bit more power, say 2kw to
5kw?  What I like about the WhisperGen is that it seems to be a fuel
miser, has low emissions, and like most marine generators, produces hot
water instead of wasting the heat aborbed in a normal cooling system.
Thanks.  glenn



The DC WhisperGenTM is designed to be used as an electricity generator
that also produces heat. The system is designed to charge batteries
such as those used to provide electricity in remote homes, boats or
other mobile applications.

The WhisperGenTM will provide more than enough electricity and heat to
satisfy the requirements of an average boat or off-grid home, providing
both electricity and heating with minimal noise and extremely low
exhaust emissions.

The WhisperGenTM operates unobtrusively with a noise level similar to a
domestic air-conditioner. Lightweight, compact and efficient, the
WhisperGenTM converts over 90% of the fuel supplied into heat and

The WhisperGenTM incorporates an advanced battery management and
charging system, controlling charging through a three-stage cycle
(bulk, absorption, and float) to maximise battery life.

At times of high electrical load, the battery bank acts as a buffer of
electrical energy, ensuring a continous supply of electrical power,
even when consumption outstrips generation.

Utilising the highest quality materials, the WhisperGenTM requires
minimal maintenance. The system's Stirling engine contains no oil,
eliminating the need for oil and filter changes.

Operating automatically to maintain heat and battery bank levels, the
WhisperGenTM is set via a remote-mounted panel, with a sophisticated
control system incorporating battery management, charge control, heat
management and self-diagnostic sub-systems.

Why not just parallel a couple of WhisperGens?  They make an AC unit
"now" that looks grid-tied, so adding those in parallel might be

[Have you checked the prices on these things?]

Sorry it's taken so long for me to get back to you.  It's a good idea
to put them in parallel but I'd have to use at least 3 and that get's a
bit complex/expensive.  Thanks!

http://www.ccslightning.com/  uses a Kubota diesel engine.  It is made for
trucks when the driver wants to sleep.  A derivative of this is used as an
APU on GM light military tanks.  Look around the parent web site
www.mechron.com as well for some bigger power solutions.

And here is another that specializes in off-grid DC power:

PolarPower site is terrific.  It approaches the issues more
systematic/holistic.  Thanks!
