Display MoreYou really like spinning things to make them fit your version of the Rossi story.
You write "a conventional 40 MW heater costs roughly $60 million." Yet your link further down shows that is a the cost for a geothermal heater - hardly conventional.
A glass container furnace making 400 tons/day @ 4.5 MMBYU/ton:
400 x 4.5 x 10^6 / 24 = 75 million BTU per hour= 22 megawatts
It costs a fraction of that and a steam furnace much less.
In passing, why don't the operators around it, in a building with just natural ventilation, all die when you say just 1 MW would kill at Doral, with much lower radiation?
I agree with Stefan.
To answer AA's points more fully:
1MW is problematic at Doral because of the LACK of natural ventilation up to the task. The comparison with a glass furnace is ridiculous, glass furnaces have large flues and void heat to the atmosphere through these. The existence of a tall large flue, with gasses emitted at high temperature, causes forced cooling which although natural creates an airflow equivalent to a very large fan. Doral had no such large flue, nor a 400C heat source to drive it!

A 20MW heating source is not comparable to a 20MW glass furnace because the 20MW must be properly dissipated in steam or hot water and distributed to its end use point with a closed loop system.
