TransCanada Overpass
A series of overpasses has been built to
get wildlife safely across the TransCanada Highway in Banff National Park.
Unlike some of the paintings that I have ‘randomly’
selected as haiga backgrounds for the computer-generated haiku, these structures
have very little to do with energy storage, other than to look very cold in
mid-winter just after sunset.
By way of explaining the haiku… An air source
heat pump is a system which transfers heat from outside to inside a building,
based on the principal that air at any temperature above absolute zero contains
some energy, and involving a compressor
and a condenser to absorb and then release heat. On-going research aims to find
an efficient combination of air source heat pumps and salt-solution energy
storage to smooth out the variable efficiency of the heat pump, a problem shared by all weather dependent, non-combustion energy sources.
