As a non-technical person who greatly enjoys and respects this forum
I am extremely cautious about opening new threads, so I have thought long
and hard about this and I think the time is right. I hope the brain trust
here will take a little time to answer.
My question: why would this
Well I spent an hour or so in the HVAC world and sure enough Jed was right.
Apparently the standard for measuring air flow in a round duct involves
checking wind speed in 18 locations along three separate axes, which is
probably not practical when you are trying to assess air flow in a dynamic
syst
I have had wretched experiences trying to do air-flow calorimetery. It is
done by HVAC installers on a daily basis, so it does work, although I
gather it is imprecise. I know it is hard to do right.
The hard parts are determining the flow rate of air, and finding the
temperature, which varies in t
I am probably naive. However, it seems to me that if one design a loop
back, an absolute measurement can be had.
Once the Ecat is at full operation let the ecat generate steam and run a
turbine with an electrical generator. As the COP for the turbine is well
known exact knowledge can be determined
no small rankine turbines or steam engines are that efficient. Best bet
would be a stirling engine from qnergy http://www.qnergy.com/. About 3kW
output and 30-35% efficient and designed to feed into the grid. If run in

a tall well insulated chimney would sort that out, and flow velocity (and
hence mass flow) in chimney can be accurately inferred from temperature
given column pressure differential caused by air density difference.

you have to add to the losses of the turbine, the losses of the battery
required, (the rest , electronics can be efficient) that may be 50% from in
to out later
maybe supercapacitor/nonsupercapacitor can help, or freewheel?
