[Gasification] 2 MWe Gasifier at University of British Columbia, Vancouver, Canada

[Lloyd Helferty]

Thank you very much, Tom, for this information!

   Nexterra is certainly a company that I have been keeping my eyes on 
for a while (since at least 2008).
 >3,000 hours in a GE Jenbacher engine is certainly a significant 
milestone, and not to be ignored, especially since this could translate 
into applications in Schools, Military installations, Community 
Facilities, as well as Commercial and small industrial applications 
(>10, <60 MMBtu/h) -- in addition to other (Northern) applications such 
as Greenhouses.
   [Global warming or not, Canada will /always/ be a cold country in the 
winter -- the tilt of the Earth is not changing...  So we absolutely 
/need/ HEAT to (at least) prevent the pipes from bursting in all of our 
buildings in the winter. (We have no choice there -- in the north one 
cannot simply insulate and allow a building to cool to the average 
ambient temperature.)]

**Even in Toronto -- the most southerly part of Canada -- the Average 
Annual (heating) degree-days (below 18C) is about 3000.
  If the (heating) Degree-days are above 6570, this means that the 
average Annual temperature for that location is zero [0] degrees C, or 
-32F.  i.e. The yellow parts of this map:
