I actually make my own, using a secret formula of ink. I can print them in my inkjet printer... I'm hoping to perfect the formulation of a new "solar cell" paint, so that I can make large panels more easily...

Send me $49.95 and I'll give you the rest of the information, its real easy!

If your local soil is deficient in selenium, don't worry, we can use bamboo to extract silicon instead.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I suppose the rest of the formula involves rolling it up and smokin' it?

Brent Swain has a home mede wind generator on his boat. Works very well. e-bay generator and a home made blade out of a 2 x 4 gives him a steady 2 amps. He has to strap the prop on occasion so he doesn't over charge...

His book has several - DIY projects for budget wise boaters. do a web search for Brent swain - his book is called origami boatbuilding.

" a home made blade out of a 2 x 4 gives him a steady 2 amps. "
I have to wonder how the time and effort, and skills, to whittle a perfectly good 2x4 down to a propellor blade, compare to just peddling a crankset generator to get those same two amps?
