Polish Water Clams

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)

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.

In his podcast this week, Blindboy played an excellent live interview with Brenda & John Romero, who are video game royalty. Brenda is a fullbright scholar and has been working in the games industry since 1981, and John was a game designer on Doom, Quake and Wolfenstein 3D. The interview is an enjoyable listen into the world of video game history, including the large role that women have played in computer programming history. Brenda and John also describe the new game their company in Galway is building called Empire of Sin, which includes an Irish gangster that uses a hurley to beat up his rivals!
