Summary
Credit: Cassie Langstraat
In Podcast 293, Paul, Rick, Jason, Steve Heckeroth, and Stuart Davis summarize the week long solar workshop that just took place at the laboratory.
Paul starts off by talking about the
skiddable bee hut that teepee dwellers, Tony and Emily, finished this week. He also announces that Tony and Emily are leaving so they are looking for someone, preferably a couple, to live in the teepee and continue experimenting with the
rocket mass heater.
Paul and the crew then start in on talking about the week and note that the weather was less than ideal. They thought the week before solstice would be perfect for lots of solar projects but forgot that June gets the highest rainfall of the year in Montana. So, the first two days ended up being a lot of indoor presentations.
Paul takes a second to boast that after a disagreement regarding CFL's, Steve has finally agreed that he too likes
LED lights much better than the alternative.
One of the first presentations was the How To for the
electric tractor by Steve Heckeroth. He presented his newer model which has 48 volts, a loader, a PTO, 3 point hitch, 2- wheel drive, and 24 horse power. It also has the ability to have 2 swappable battery packs along with the fixed one underneath the seat.
Another
project they worked on was the House Backup Power, a concept Steven Harris brought onto the scene. Basically, it is a set of batteries that gets all charged up so that you can use them when the power goes out instead of a noisy, expensive generator. Someone else notes that Steven uses this in combination with emergency power from the back of a truck.
Paul takes a second to mention the land next to theirs got bought by friends of his who want him to manage it. They want to do some deep roots stuff there and are offering two acres for $8,000 in the first section and two acres for $16,000 on any section. They are very "pro-child" and would like to have families living here. Check out if this offer is still available
here.
The guys take a while to discuss
huckleberry pie, their all-time favorite pies, and other Missoula treats.
Then they begin discussing the Heliostat, which is currently having some problems. The idea is that no matter where the sun is, it will keep a certain spot illuminated as long as the sun is out but it is having some problems at the moment.
On to the "Tale of Two Poopers", as Paul titles it. He talks about one
pooper that took them 3 months to build that had some problems and compared it to the new one that only took 2 days to build. The second one has a solar element in having one solar panel, a battery, and a fan so the air pressure is lower where the poopy bits are and the air pressure is higher where the people are. This design has been very successful.
They talk a little bit more about
composting toilets, Steve's awesome
stump outhouse, and how they have been letting the poo from the laboratory's pooper hang out in a sealed bucket with some black soldier flies. It
should be done soon.
The last project they talk about on this podcast is Tim's truck. It is another idea by Steven Harris, just a little beefed up. Basically, it is a big toolbox that has batteries, a charge controller, and an inverter in it with wires that run up to the alternator. The theory is that when you have excess electricity, it charges the batteries in the back of the truck. So you have a generator and a bank of batteries for electrical use. Tim has a 3000 watt inverter.
The guys get a little bit into discussing the
energy it takes to charge the batteries before the podcast ends.
