Data centres are infamous for gobbling up plenty of power, so IT consultancy Comtec Enterprises is using hydrogen fuel cells - developed by APC - as a back-up power supply for its data centres.
The fuel cell converts the chemical energy produced by mixing hydrogen and oxygen from the air to churn out the electrical energy needed to power the servers with three 10kW cells.
The fuel cells are supplied with hydrogen from stored and pressurised bottles via the pictured tubes. These pipes also extract water produced by the cells.

I have a recolection of reading a story in an old copy of 'Wireles World' from over 50 years ago. In those days, cars were required to have a parking light when parked in the road at night. An unlucky person had been prosecuted for powering his parking light from the emissions of the local radio station at Rugby.
