Human Skybeam

An art project for Burning Man 2004

design

A shimmering column of light on the horizon: it flares and ebbs, shifts hue, reaches for the heavens. A beacon, a signal, a mystery. The curious wanderer follows to its base, searching for the beam's source, and thus its explanation; they find a spotlight atop a small tower, with three stationary bicycles at its base. The observer climbs aboard and begins pedalling; the electricity they generate keeps the light burning, thus helping to draw in the next round of curious onlookers.

Each bike drives one of the primary colors, so the beam's hue changes according to the number of participants and the amount of energy each one produces. A solo wanderer can pick their favorite color. Groups can cooperate, trying to produce some particular color, or to balance their energy to produce pure white light; or they can simply compete to see who can make their light brightest.

An interesting project from 2002, involving a very bright spotlight.

Prebuilt voltage regulators, designed for caving headlamps; they sell a 12 volt option, and the site has schematics.

The big light on top of the Space Needle is also called a "skybeam", though the only references I can find are from sites complaining about it as a source of light pollution.

Another possible source for a commercial voltage regulator; this is a little discussion of some Volkswagen parts.

"Tribute in Light" for the World Trade Center

The Luxor Hotel in Las Vegas has a very bright spotlight at the tip of its pyramid that helped inspire this project.

Savant atibax ciprofloxacina 500 mg/kg), which significantly increased the total number and size of the intestinal lesions. lesions produced a significant inflammatory response in both the experimental group and control mice. The lesions in experimental group were comparable to those seen in human IBD. The results demonstrate that this compound reduces the development of IBD, especially in genetically susceptible mice.
