Re: [PSUBS-MAILIST] Millennium Cell HydroPak



Bryce,

As a reference for power consumption, my K-350 draws around 4.5KW. If more power was available at a reasonable price, I would have upped the thruster HP to a draw of maybe 6.5KW. Any more then that and it would be very difficult to steer.

On the subject of Hydrogen Fuel Cell Systems.. how much power does a TYPICAL PSUB draw? I have done some research on systems and they can produce massive amounts of KW, but it is the Amps I am worried about. The systems I have been investigating are also designed for transportation systems, both automotive and transit bus, which does not eliminate it from the larger psubs.

Also on a side note, sorry I have not been around in such a while, but after going through all of the emails lately, I have been recharged and am ready to get to work (or at least planning that is. :-) )

Hi Brent,

the water vapor comes from the electrical production (like of), then
then hydrogen combines with the oxygen in the fuel cell, it will from
water (while releasing electrons we can use).  This is water vapor
I would like to capture.

Using a water absorption cartridges would work, although this means
planning carrying extra if you plan to operate the fuel cell.   Maybe
a simple condenser would work, using waste heat or a little power
from the fuel cell.

Also, another question to ask the Millennium Cell people.  How hot
does it run?  Can we use that heat (or get rid of it if we don't
want it)?

Cheers,
Ian.

Ian,

Interesting information. From the looks of the date on there PDF file, they have larger units planned as well. Also there is a note about it being safe for indoor use with zero harmful emissions claimed. I'm still not sure if the cartridges take O2 out of the air, but it doesn't look like you have to provide any from a tank. I'm not sure what your talking about with regards to water vapor collection. It sounds like you just pour some water into the unit of which goes into the cartridge starting a chemical reaction. I wouldn't expect all that much water vapor to come out of it. But if there was you could have it's vent going directly into your air circulation system that has water absorption cartridges inline.
