Nij Bosma Zathe is an experimental Dutch farm with 200 dairy cows. The manure these cows produce is used to make biogas. The gas is turned into electricity in a generator which feeds it into the national grid. The heat this releases goes directly to houses in the new estate in Techum.
The heat arrives, through a grate in the wall, in Carla Koelstra's home five kilometres away. "Just a push of the button and the house is warm," she says. Her children are surprised it doesn't smell: "They must use a lot of perfume on it."
As a result of the economic recession, not all the houses planned for this neighbourhood have been finished. Less than a hundred are now heated by means of biogas.
