Gravity of Light
Upon Courtney's suggestion, she, Dave, and I went to the Gravity of Light visual art presentation this week during lunch. It was set up in an old warehouse that Dave and I both bike past every day on our way to work. The artists, from Brooklyn, set up several large scale pieces along the walls of the Pipe Building and illuminated the room with the blindingly stark light of a 50,000 W carbon arc lamp.
The carbon arc lamp itself was fascinating. Basically, the mechanism brings two charged carbon elements together and pulls them apart, creating an arc in the space in between. The process burns off some of the material, so the mechanism slowly brings the rods closer and closer to keep the arc distance approximately the same over time. The light it cast was brilliantly white and caused amazingly sharp-edged shadows throughout the warehouse. It was a good experience.

Not quite a snowy commute
I have no picture, but wanted to document that today was my first ride in to work with snow. Of course, it was a grand total of maybe 10 flakes, but snow nonetheless. I need to get wider tires with tread for the bike. The narrow road slicks on there are going to serve me poorly when it gets wetter and/or icy.
With the beard, I can still ride to work without the face mask to stay warm. I might try out some goggles, as my eyes water the whole way. I remember the tears freezing on my cheeks and beard in previous winters.

Presentation is over
The presentation went well. I'm glad it's over. I have to admit, despite the stress of putting together an hour and a half of material, it was kind of fun. The presentation part went fine. I didn't have a mic, so some people in the full room had trouble hearing me in the back. Overall, we got positive feedback. For the kid that about wet his pants in nervousness in high school speech class, it's kind of funny to be pretty comfortable talking to 50-100 people once or twice a year... This is my second presentation at the EEBA conferences. I've presented papers at two others.
EEBA is the Energy and Environmental Building Association. There is one more day left in the conference, so I'll get to do the rest without the cloud of the never-finished presentation hanging over me.

Water heater or sci-fi bomb
Well, it's not nearly as cool as the Maker Faire in Austin this week, but this electric water heater was sure a looker. That turbine-looking device is the flow sensor. It provides the computer some idea of the flow rate of the water so it knows how hard to pulse the heating elements hidden in those sexy stainless steel tubes. Of course, the timer is there so you know how long you have to get off the ship before the core goes critical and you need to be at least two parsecs from the resultant thermonuclear explosion.
