Thermoelectric Stoves

Low Tech Magazine published an interesting article on equipping a stove with a thermoelectrical generator (TEG). A TEG is about 5% efficient at generating electricity, however if the heat from the stove is being generated anyway for other reasons (heating, cooking etc), then adding a TEG would be a more reliable way to generate electricity than installing solar panels.

Polish Water Clams

#213

The city water supply of Warsaw in Poland uses a rotating team of 8 clams to test the water quality of the supply. If the clams close after detecting toxins in the water supply, they complete a circuit which trips and alarm and shuts off the water supply of the city. (H/T to Mikael for sharing this)

Co2 Emissions On The Web

#198

Danny Van Kooten crunches the numbers on Co2 emissions for websites with high traffic in a recent blog post. He calculates that reducing file size by 1KB on a file that is loaded by 2 million websites reduces emissions by ~2950kg per month. That equates to 5 transatlantic flights between New York and Amsterdam.
