Carlos!
Thanks for the come-back. Even after all this time I have not been
able to locate anybody who has given as much thought as he to the
heating of air by mechanical means. I am aware of several patents
going back to the 19th Century but it was the thoroughness of his own
approach that interested me and that fact that the units had been
installed and were working correctly - at least they were at the time
his book was written in the early 80's. Somewhere I still have a copy
- which I got from the ITDG bookshop in London.
Would you (or anyone else) happen to know where Reinhold can be
contacted? I would very much like to see a unit in operation, wherever
that may be...... except perhaps for Nepal, where I understand that
the political situation is deteriorating on a daily basis.
Regards,
GB
