[1] Bertolli makes yummy stuff (not long ago they built a plant in Ames,
Iowa - about 20 miles north of me). They make a two-olive spaghetti
sauce that I particularly like.

[2] The "pop-pop" boat looks like the kind of toy I'd have /really/
enjoyed as a kid - and that I'd have had a ball building with my boys
when they were kids. It's even fun just to hear running. :)

In the context of multi-horsepower solar pumps for irrigation and
village water supplies, I think they probably aren't the right choice
(but I'd be absolutely thrilled to be proven wrong!).

This past week I added an oxy-acetylene torch and a tubing expander to
my set of shop tools so I can braze copper tubes for solar engines. Now
I suppose I'll be wanting to build a pop-pop to play with...

Troublemaker. I was just wondering how big the tubing (and how much
heat) I'd need to for a pop-pop engine on a 12-foot kayak. :-]

Oh. I *know*.


1) Please forgo the flexible metal top on *that* boiler.
    Can you imagine the racket?  Whoa.

2) A couple mm^3 of flash steam is different from 1m^3 of
    flash steam, safety-wise, yes?

I'm just sayin.

How about water power?

Two tanks with heavy floats, one above the other. The floats (a rock
in a pail) are on opposite ends of the mechanism that moves the
tracker. The valve that lets water flow from the upper to the lower
tank is a car radiator thermostat or a greenhouse vent opener and
kinked hose, placed on the afternoon side so it lets water through
when heated and shuts when the moving collector shadows it.

The flow rate regulator that keeps the collector from overshooting is
a rag stuffed in the outlet of the upper tank. It also keeps dirt from
holding the valve open.

Strong winds can overpower the floats to feather the collector, and
nothing breaks if they jam.

The farmer pours the water back into the upper tank each morning.
