My wife thinks I should build a windmill on the roof, to make

Unfortunately I don't think your lot is large enough to do this legally
(not many in SF are)... of course, maybe no one would notice.

I sorta think they might.

I'd look into a turnstile-type windmill, and see what kind of regulations
there are about putting stuff like TV antennas on your roof. ;-)

How about replacing the cross on Mt. Davidson with a windmill?

A windmill to commerate the Armenian genocide? I don't recall it being
very windy up there anyhow.

What I really want is a well in the back yard.

Is there anyplace left in the USA where it's still legal to dig a well?

My dad has a well and a septic system, nicely spaced. Everybody in
Folsom, LA has a well. So does my brother-in-law in western Mass.
Charlemont, Mass has public sewage but no public water supply.

How about a septic tank and cesspool/drain field? I bet you could plant
some pretty rich crops on top of a drain field. ;-)

Septic tanks with drain fields are still common in various burbs.
There are lots of places with no public plumbing at all.

John

for the windmill idea.. there is a video at the top of this page that
shows a wind turbine from australia that is actually going into
production. it sits on on the ridge of the house and picks up wind as
it picks up the speed near the top of the roof slope.

Ludicrous.

Larkin,

Maybe if you'd use your imagination you could create something, then
you'd be less likely to be such a downer and poo poo everyone else's
efforts. I think you are just a grumpy crank who needs to get laid.

Try to feel better.


There is a big difference between getting laid and fantasizing about
getting laid. And there is a bug difference between generating energy
and fantasizing about it. The rooftop "turbine" shown was all fantasy;
it could barely spin itself, much less generate useful amounts of
electricity. Anybody can build a thing that spins in the wind, enough
to impress reporters and politicians.

Your imagination doesn't make the numbers change. Engineers build
things that *work*. If you want ooh-aah enthusiasm for crackpot
machines, post to a newsgroup where nobody understands physics or
thermo or economics.

People here would be impressed and delighted with something cool that
actually works. If that barrel turbine, or the water wheel, is
commercially successful, I'll humbly apologize. Keep an eye on them
for me, OK?

John




The boundary condition velocity of wind on any rooftop is, by definition, ZERO.

That is why windmills are normally on towers.
