Not sure what they would gain by converting to fuel cells as the article suggests. They probably would still require onsite storage for their hydrogen source in order to insure uniterupted supply, either hydrogen, lng, natural gas or propane. what's better in a fire, a heating oil tank or a propane tank?
How about using water power for backup? Store a big tank of water on the top floor and use a water turbine to generate power in an emergency... Wonder how much water it would take... but for sure this would do well in case of fire. -- -------------------------------------------------------------------- jullrich@euclidian.com Collaborative Intrusion Detection join http://www.dshield.org
