BTW:
In searching for the roof spray patent I found this:

That may be prior art that precedes one of the latest patents from NASA
--- its for a golf ball that has aerodynamically more efficient
ellipsoidal dimples. The wonder of socialism at work In America !!!

The water spray idea could be a nice product business where there is
plenty of water. There may be room for some new inventions there.
BTW, If you are working on an idea, write me, and I'll get you in touch
with the right people. Do talk to your Patent Agent first or we'll help
you to find one, and do not talk to others regarding your idea. Least of
all on Usenet. No, you don't pay anyone to market your ideas - that's a
scam. We help you to get your idea developed, drawn, patented,
prototyped, and presentable. Sometimes we can help you to find capital
for you for your development purposes, or more importantly, we are a
self-help forum for technical ideas of all sorts.
