Being green and frugal in true geek fashion [Mod]

While not your typical “mod” (usually depicting some sort of computerized machine) the LED light hack “Mathias” whipped up with his fish tank and new LED lighting shows that being green can actually be pretty geeky and cost effective.

By replacing the old fluorescent bulb over his massive fish tank and swapping it with an LED, he garnered quite a bit of savings up front. Next, he routed heating tubes through the light mounts to suck up any excess heat from the LED’s and in turn used it to heat up the water.

Ingenuity folks. It’s all about ingenuity. Anyone care to share their feats of geek strength?
