From considerations of conservation of coal and 
economical use of money electric air heating by power 
furnished from turbo-electric plants is not possible. 
' But how about hydro-electric power, it may be asked. 
It would require an installed generating capacity. of 
at least 500,000 kw., conservatively estimated, to heat Salt 
Lake City. Now, in the first place there is not this much 
hydro-electric power available or developable in the State 
of Utah. In the second place it would cost $200.00, or 
more, per kw. to build the plants, lines, etc., to get the 
developable hydro-electric power to the city. Hence, when 
the fixed, operating and maintenance charges were paid 
it would be found that hydro-electric power would cost 
practically as much as steam-electric power. 
Electric heating is, from an economic standpoint, a 
sort of alchemist’s dream. We all know that electricity 
does produce heat, and we all realize and appreciate what 
a wonderful thing it would be to dispose of our coal piles 
and ash pits, and smoke, dust and cinders, and would. 
therefore fain think it practicable. But a most cursory. 
study of the subject, either from the stand-point of ther- 
mal dynamics, or social or economic science, show that it . 
is utterly impossible of general application.
