Interesting read. The example he used was a 1400sf drive using a 250k condensing boiler. That works out to 178btu/SF. Makes sense that he recommends using condensing boiler over conventional since the return temps are so drastically different and it does not require tempering of the supply or return water.
Seems like a 'uge investment as well to excavate, reinforce, insulate and pour the drive. 1400sf driveway could easily run 30k for install.

After reading that article, i have decided that even tho i had no plans to install a melting driveway system... i am not going to plan for installing one. :o

A snowblower or snowplow or loader to remove the snow & coal cinders for anti-skid seem like the best plan. :)

I am still racking in my brain, the thought of a snow melt for my deck, I am putting it on this summer, 10’x92’.

But that would include a water to water exchanger, glycol for the deck side, pump, expansion tank, controls, the aluminum transfer plates.. and then being exposed to the atmosphere idk how well it would work anyways, I am doing 2”x6” deck boards.

I think we should brainstorm on a steam powered airplane too.

Noooo.... For a year and a half starting in late 1955 the USA played with a modified Convair NB-36 that carried a small nuclear reactor, but it was only used for testing shielding. The reactor never supplied energy for flight. In the early 60's they built one or two nuclear aircraft engines, but they never put them in an aircraft & the project was cancelled after nuclear subs proved to be a much wiser idea. Oops...are we getting off topic?
