Thank you very much, Tom, for this information!<br>
<br>
Nexterra is certainly a company that I have been keeping my eyes
on for a while (since at least 2008).<br>
>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.<br>
[Global warming or not, Canada will <i>always</i> be a cold
country in the winter -- the tilt of the Earth is not changing...
So we absolutely <i>need</i> 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.)]<br>
<br>
**Even in Toronto -- the most southerly part of Canada -- the
Average Annual (heating) degree-days (below 18C) is about 3000.<br>
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:<br>
