			Spoke to Marcin and finalized BOM. Added link to BOM in presentaion: https://docs.google.com/spreadsheets/d/11pQpi5mwnDAgyS1EWNWjtcWksAiQFCGRM11gsAuMC9k/edit#gid=0
			Researched insulation and charge controllers and voltage converters. Hopefully found good solutions. Could probably design simple buck/boost converters myself in the future. Will look into it.

	Quick sketch of wiring added to Google Slides presentation. Also updated Bill of Materials to what will hopefully be its final form for this build. Not sure yet exactly how much compound to order. Check Tuesday, October 18th, 2016 entry for calculation of free space between pipes between modules. I am also assuming there will be fasteners, fittings, and steel plating available at the farm for clamping all pipes together and attaching hose. Have reached out to supplier of silicone glue inquiring as to its removal once cured in case we want to salvage the modules for a later iteration of the TEG. Awaiting response.

Just remembered, we still need less expensive thermal insulation in between modules and around entire generator. Foam sheets cut to fit?

			Fritzing software not making much sense to me. Also not sure how to regulate the voltage from the TEG to a stable 24 Volts. Probably won't have time to solve this problem before the build, but we will at least have the TEG working and producing measurable voltage and current. As Marcin said, this build doesn't simply stop after the workshop, so there's always the next iteration to look forward to. Also cannot find a good putty to insulate in between the old and hot pipes in between the modules that isn't going to cost us over $100. Maybe we can just cut some foam to fit in the spaces. The putty would also jeopardize our ability to retrieve the modules after the build since it hardens like ceramic or concrete, so this is probably for the best.

			Wasn't able to meet with Alex for a crash course in welding, either. AND I still can't find the hole in my sleeping pad. Not a great week, but this week will be better, and I'll be headed to MO on Monday, so lots to look forward to.

			Updating the BOM tonight since we need to get things ordered soon. Hope this works!

	Uploaded two FreeCAD files detailing the geometry of the TEG modules laid out on a pipe. Created new BOM with links and added it to the end of the presentation. Researched pressure and safety regarding the hot water reservoir, but didn't find much. Need to get a pressure relief valve that can be set to about 140 degrees C. Is the 50% efficiency already taken into account on the datasheet for the TEG Modules? Talked to Marcin on phone. Great conversation, lots to think about. Now prioritizing finding experts to assist and review designs and BOM, getting the BOM finalized, and making an electrical diagram of the system and its connections.

	Calculated volume of insulating material needed to fill the 3.4mm tall spaces in between the individual TEG modules to insulate the cold water and hot water pipes from each other everywhere that a TEG module doesn't connect them. (152.4×762-40×40×24)×3.4×4 = 1.05711168 × 10^6 mm^3 or 35.745198 fl oz (fluid ounces) or about 1/3 gallon for the space between and around each TEG module total for all four sets of 24 TEG modules sandwiched between a hot and cold pipe.
