Alan, My remarks are intended to contribute discussion of technologies which seem neglected that may prove of great importance at this time of rapid Global heating.
There are alternatives which I do not see mentioned. There is also a sense we are running out of time.
I have not posted here for many months. And have little interest in self promotion. Most of what I have mentioned belongs to other companies. AESOP Institute is a non-profit and this is an educational effort.
Although we have a commercial affiliate the Institute tries to inform about little known alternatives.
