EP.  Many thanks for all your good work, not just this piece but all the great things you have on your ergosphere.  

I think a lot of people get self-confused when they get into the habit of abbreviating kilowatt-hrs to kilowatts, as in "My electric bill showed only 213 kilowatts last month". From there  to kilowatts per hour is a swift slide down the steep slippery slope.

BTW, I have finally got a thin stream of  vital fluids flowing again toward completion of my 1kW home power stirling engine and shall give a full report asap.  The military industrial vampire had sucked it dry for an entire year (goddamit).

I'm looking forward to reading about it.
