I never needed/used magnets, and my ?failed inventions? are improving  
lives in three countries so far. That?s not much, but it?s a step in the  
right direction. Thanks for asking. :-)

What have you done to make life better Harry?
What ideas have you come up with recently or ever?
Morris has accomplished a fair amount on the budget he has.
You are just breathing our air and reducing its' oxygen content it
seems.

Aren't you the guy with the heat absorbers with the curved vanes
and the three way air flow?
Anything interesting going on there?

A draft tutorial and project write-up with photos and CAD drawing is  
online at http://www.iedu.com/Solar/Panels  - and there?s a guy in  
Edinburgh who agreed to do a DIY assembly video for less than I would  
have had to pay for the software to do the job myself. I'll put the  
video on the web site as soon as it?s ready.

Beside the panels already installed in the US and Canada, more are being  
built in Poland, there are tentative plans for a teaching workshop in  
Greece, and I'm kinda hoping to see something similar happen in Spain.  
Other than being available as a long distance coach, I'm not personally  
involved with any of the offshore activity.

Most of my recent effort has been focused on an MHD electrical generator  
and a LENR heat source. You can catch a glimpse of this project at  
http://www.iedu.com/Solar/Electricity . To me, it?s at least as  
interesting as the passive solar heating panels, but progress is slow  
enough (from a spectator perspective) to be about as exciting as  
watching paint dry.

Oh, Morris...say it isn't so!!!
You've gone over to the dark side.
You had a wonderful, easily reproduced solar dwelling heater.

I tried to read your links, but couldn't get the videos to play.
I did skim the MHD book.  I'm not the slightest bit interested
in reliving math experiences from 50 years ago...but there were
some interesting statements glossed over.
MHD seems to work with a uni-directional flow of ionized material.
If you're sloshing it back and forth, there are all kinds of
issues with reversing the flow of massive ions.  And there's the
tiny detail of superconducting magnets.  And the 0.2Volt output.


I had a few questions...
About  the MHD generator.  What does the math say about heat flow?
For every kW of heat input to the hot center,
How many watts of real usable electricity at usable voltage do you get out
and how many watts get lost keeping the cold ends cold and the magnet
energized and the other implementation details?

And how does that compare to a classical steam turbine at those temps.
No moving parts is attractive, but if you have to put the moving
parts back in the compressors to manage superconducting magnets, is it
worth it?

About LENR...
If Rossi could make it work, you'd be able to buy 'em at home depot
by now.
If he can't, I wouldn't have a prayer of making it work.
And even if I did, I couldn't afford the boatload of patent lawyers
required to get it off the ground.

LENR is a fool's errand.  Don't let your wonderfully practical
side succumb to the fantasy side.
Work on stuff that obeys the currently known laws of physics
and buy magic stuff at Home Depot after Rossi gets it working.

;-)

How's that for a discussion starter?
