Thank you for your email and reference list about hurricane
suppression.
I attach a paper about the Intellectual Ventures wave-sink given
to the 2009 EWTEC wave energy conference.�
You can see video of a tank test of a 1:100 scale model from the
drop box at��
https://www.dropbox.com/sh/c852tpue32fr5iy/nQDRPbSO_p�����������������
It is the right hand tab.
The rate of water down flow can be measured by the black bin bag�
slowly growing below. The tangle of rods below are nothing to do
with the model, just some work platforms. �
If the bag extends by one bag diameter the volume at full scale
would be 785,000 cubic metres.� Time goes with the square root of
scale so this would take ten times longer than it would have done
in the video.� You can time it yourself but I make it about 80
seconds model time so at full scale we would be moving nearly 1000
cubic metres a second.�� An important point about this experiment
was that the downwave valves were working as well as the upwave
ones.� I hope that the full scale ones will leak much less.
You can download a Powerpoint with notes called /Uppsala
hurricanes in the /Hurricanes folder at
www.see.ed.ac.uk/~shs���
It is 35 Mb which is too big to attach to an email.
As figure 1 of the second attachment (Whitney and Hobgood) shows,�
severe typhoons and hurricanes happen when the sea surface gets
too warm.� Both marine cloud brightening and wave sinks might just
have been able to reduce the recent damage in the Philippines by
using them to bring water temperature back to the values for
smaller storms.� Perhaps this possibility will make the people who
attacked the ideas think carefully.� Did their attacks reduce the
chance of research funding?
