@Tom P, interesting idea... Send steam out, get steam returned back, pretend you just boiled some water. The problem is the pipe diameters as seen in photos of the shipping container.
The outlet pipe looks to be about 125mm diameter. In order to send 1MW of steam down such a pipe, the steam velocity would be approx 25m/s. The return pipe looks to be about 25mm in diameter, a 25 times reduction in cross sectional area.
This means if this pipe contains steam, it's velocity would be approx. 525m/s... 1.55x the speed of sound! (This would be a very bad thing from an engineering/safety perspective)
Dewey Weaver... If you don't mind me saying, I think you should stick to what you are good at, namely venture capitalism, and trolling forums - not pontificating on thermodynamics. To reply to a post full of numbers with a sarcastic comment is pretty bad form anywhere, but particularly so on a science forum.
Sure, I didn't include all my workings as (a) it would have taken to long to type, (b) people don't want to read about Nusselt and Prandtl numbers, (c) anyone with the ability to check my workings will likely have their own spreadsheets or simulators if they want to check what I said is correct.
Really, you should be more grateful. I just saved you $1000's of dollars that you could of blown on having someone model this...
The thing is, thermodynamics isn't an art... it's a science. It's based 100 year old theories and 'simple' calculations. Hence (unless the shipping container is crammed into a tiny little room) anyone you pay to do the calcs will get pretty much the same answers as I gave.
Unless you have some proper drawings for what's inside the 250kW ecats (i.e. insulation type(s) and thickness), it will be a useless exercise anyway... My calculations are only intended to show that it would be exceptionally easy to design a system that doesn't "boil your fish bowl" or whatever expression you wish to use... Between 10 to 50mm of bog-standard insulation is all that's necessary.
One little hint: When you are looking for your expert to do this supposed thermal modelling, make sure they have an engineering qualifications; Japanese language translators, who have once visited a ships engine room, are rarely up to the necessary calibre... Including have been running their own LENR library for years.
EDIT: The fourth picture down this page shows 4.4MW's of boiler stuck in a basement, with a HVAC system smaller than found in a small (500 person) nightclub. Funny that.
