Hydro plant with 2 nozzles, (a.k.a. "Schnödels" in German) generating 200w continuously with 17' head and about 1gal/sec volume. It has a brass turgo wheel, which looks like the fan in a jet engine. The generator itself is a permanent magnet setup, which are glued under the spinning hub, the pick up coils are embedded in the epoxy below. By raising and lowering the hub, I can optimize the resistance of the magnetic fields versus the available power from the water pressure...if that makes any sense to you. The fogged up box contains a heat coil, to which power gets diverted when the battery reaches overfull conditions, as determined by voltage regulator. The other image is my catchment, with a high tech refrigerator grill as an intake filter. Solar panels generate my power in the summer, and a little yamaha 3Kw genny is there as backup...hardly ever runs.
Here is my shop for cedar kayak and furniture building, with attached greenhouse and solar panels in front.
Since Mayer asked to see my solar set up, here are my panels:
They are attached so I can tilt them as the sun moves across the sky:

Came out easy, awaiting to get chipset repaired
MacBook Pro 15" Core 2 Duo Models A1226 and A1260 Logic Board
Logic and keyboard replacement
MacBook Pro 15" Unibody 2.53 GHz Mid 2009 Logic Board
I had the additional GPU card, as mentioned by kevmacmills above, and needed to remove two Torx screws, one short one at the plastic separator, and one 7mm approx at the heatsink in the top right of the enclosure.
I did not even disconnect these cables, because they are easily damaged when reattaching. I just left them in their sockets and folded the whole assembly back and out of my way, when I needed to take out and replace the keyboard.
Nice, thank you Andrew Bookholt
If the cable broke, you can replace it for around $50ish. If the terminal broke off, I am afraid your logic board needs to be fixed(unlikely) or replaced.
I just replaced the logic board, and all went fine, as far as I can tell. However, my new battery is still in transit, i.e: I do not have it at hand. My question is, how critical is it to have a battery in this model....given all the "do not remove battery or else" warnings. Is it OK to try to boot it just with the regular power supply? I do not want to fry my new logic board, so I need some informed opinion on this...
Yo, I took out the logic board, because the display was not coming on. I had done all the other test to eliminate the chance that it was not the board.
It came out fairly easy, and I sent it away to California to get a new chipset installed to fix it. It came back, I stuck it back in, and voila, she booted up. I am thankful for your guide, it was easy to follow. Next I am replacing the logic board in an A 1286.
