			**Drew up a concept sheet and a ruff schematic for the heat bank and copper heat exchanger and got [http://wiki.cs.earlham.edu/index.php/Heat_bank_design them] on the wiki.
			*Weed of September 18th
			**Got the [http://wiki.cs.earlham.edu/index.php/Heat_exchanger_modeling math model] of the heat exchanger up on the wiki.
			**Worked for a few hours in Publisher playing around with ideas for the Green Zone pamphlet.
			**Fri. we decided on our plan for mounting the solar hot water heater at the Farm. We'll have a work day on Sat. the 30th. Looking forward to moving forward.
			*Week of September 11th
			**Worked out a mathematical model for the heat exchanger with Fonsie's help. He suggested using Newton's Law of Cooling. Had some trouble getting all the numbers I needed from our test run, but it all came together at our Friday session.
			**Fri we talked about the plans for the Green Zone.

			**A bunch of stuff has happened. We have ordered glass, had meetings, but the damn thing isn't on the roof yet. It'll happen in a week.
			**I did measurements for the way we're hoisting this monstrosity up on the roof. Serves me right for mentioning that we should decide how to do that. Details in h20 system.

			*Week of September 11th
			**Met on friday and talked about the green zone and where we all are in our respective parts of the project chose a date to work on the solar hot water heater.
			**Worked on measuring the finned pipe for quite a while. There are other pieces of pipe rusted onto it. I tried DW-40 and straining with a pipe wrench to no avail. There may be a better way to work on this, but I haven't thought of it. We could take a hacksaw to it, since we are just adding rubber elbows. But I wasn't up for doing that yet. I got as many measurements as I could, but I wasn't sure where to put them (wiki-wise.) Also it is notable that our tank is not a cube, it is whatever the rectangular equivalent is. More importantly there is a drum set in the space that Ehren and I cleaned out next to the electric hot water heater in the basement.
			*Week of September 4th
			**Met on Friday and discussed where we are with our work. Solved the two layers of seperation problem. Thought up a new design, still figuring out exactly how the heat exchangers will work.
			** Called Catron's and got an estimate from them. Turns out that they order from elsewhere but we can order whatever size we need and they'll have it in about a week. Also discovered that there are different thicknesses

	**Tue. Third-sun finished the installation of the PV panels on the roof. I had an 8am class, but I managed to document the process from 10am to 6pm using Colin's camara. I even helped a little bit. Dan and I found out from Ben that health codes typically require two levels of separation for solor hot water heat exchangers, so we're going to have to rethink our design.		**Tue.

 **So far everyone has either been out of town or too busy getting ready for the start of classes to work much on the project.  As far as I know we still need to order the glass for the solar hot water unit, and purchase the materials for the heat exchanger.  Then we just need to find a good way to mount the unit and the PV panel for the pump on the roof.

	**Tuesday: Met at the farm to try to figure out when we will meet throughout the semester. Turns out to be tricky. We chose Tuesday at 2:30 and Friday at 11. Both of which don't work at this point. Discussed heat exchangers and tried to think about whether a less of a larger tube or more of a slimmer tube will do a better job of transfering heat. Ehren's going to look into that. I'm working on tempered glass. We talked about different mounting ideas. Charlie came up with one that sounds good, ice damn free and feasible. Dan, Ehren, and I used the solar pathfinder, and happily found that only minimal shade in December will decrease the excellence of the southern roof we are planning to use.		**Tuesday: Met at the farm to try to figure out when we will meet throughout the semester.
