So where does the energy to replace 'the things that wear out' come from ? Is this solar powered electrolytic hydrogen being used ? How much did it cost ? How much power does it generate ? What's the price per kWh ? Graham

The emissions he was talking about are NOX, not CO2, and there's no hydrogen involved anywhere. www.mohegan.nsn.us/docs/Mohegan_Sun_Report_Final.pdf

We don't get a lot of sun up this way (New England). And as I said before. they have trees all around the place. there are no form of solar energy collections system there. > How much did it cost ? How much power does it generate ? What's the price per > kWh ? I have no idea, all I know is, they operate the facility (all buildings) with these generators 24/7. The only location that is not operating with these generators is the gas station and store the tribe has which sits just out side the grounds of the casino. They run on commercial power and are backed up via their generators if needed. And as for the Casino area. there is one building that has commercial back up which is where the bank and things like that are. As far as I know, they have never had to use the commercial power since they put these units in operation. I remember a couple of years ago when there was a bad storm that knocked out service in that area for a long time. There was a near by medical facility that they supplied power to until that following weekend where they could safely switch back over to commercial again.. I think that was a nice thing for them to do. P.S. There is a river just behind the place. I think they treat that water for drinking and what ever else. Like I said, the Casino is self sufficient. The other casino not to far from it "Fox Woods" does not use fuel cell generators. They're using diesel for the generators and I do understand that they are interested in going into fuel cells if they haven't already. > Graham > -- "I'm never wrong, once i thought i was, but was mistaken" Real Programmers Do things like this. http://webpages.charter.net/jamie_5

I was told they had 3 not 2. or maybe that was 3 buildings that house the whole thing. -- "I'm never wrong, once i thought i was, but was mistaken" Real Programmers Do things like this. http://webpages.charter.net/jamie_5 |
