Super-Efficient Grow Light
This is possibly only marginally related to "local food," but bear with me. Part of eating local is, if you have the space, interest and ability, raising your own food. This time of year, folks are starting tomatoes and other seedlings, and having a grow-light is a real help in that regard, allowing your plants to get healthy light 24/7. For all their helpfulness, though, fluorescent growlights are not as efficient as they might be.
Electronics geek Mikey Sklar has figured out how to make a super-efficient grow light from pulsed LEDs. He's posted complete schematics and assembly details at his site, so you can build your own if you like tinkering with a soldering iron. He'll also sell you a finished unit if you're not up to etching your own PCBs. Energy-efficient local production...awesome.
SEPT - Super Efficient Photosynthesis. A grow light made from red and blue LEDs being pulsed. This light fits inside a Altoids container and requires less than 1.1W of energy to grow a 6"x6"x6" space. Lights can be chained to grow more plants. Total lumens = 111. Plants need primarily red (680nm) light to grow and a small amount of blue (440nm) light. By pulsing the LEDs at 720Hz or higher the plant can achieve maximum growth with a minimal amount of energy.

Hens Beyond the Backyard
The Observer has a nice piece today on backyard poultry.
Since she is the one raising them, she knows they're free-range and that she's feeding them what she thinks they should be fed. She can also tell the difference between eating free-range eggs and the non-free-range kind.
"I had eaten eggs at a restaurant once with friends, and they were so bland," she said. "I was so disappointed because free-range eggs taste really good."
"It makes a nice little hobby," she added. "Or a big hobby if you get carried away like I did."
If anyone in the club is interested in getting into backyard poultry, let me know. I'd be happy to give you some starter resources. It's a lot easier than you think, and I find my hens are far less trouble than my dog or my cats.
