European countries are leading the way harvesting heat that would otherwise be wasted as green death practices become more common. In 2011, Redditch Borough Council in England tried something that hardly anyone in the UK had heard of before. Staff announced they were going to warm the local swimming pool with heat from a nearby crematorium. The plans were met with international headlines, and a labor union official branded them "sick and an insult to residents." "All you're doing is basically heating a radiator and sending the heat down a tube," says Guy Revans, of Redditch and Bromsgrove Councils, just south of Birmingham.

On 20 November, 1945 the Nuremberg trials began - the military tribunals called to prosecute Nazi war criminals closely involved in the Holocaust. Now, 71 years later, that work continues through the Bavarian State criminal office (LKA) in Munich, that has created a virtual reality version of the Auschwitz concentration camp to assist with the continued prosecutions. Digital imaging expert Ralf Breker is behind the project: "We spent five days in Auschwitz taking laser scans of the buildings and the whole project to complete took about six months." About 1.1 million people, mostly Jews, were killed at Auschwitz, most deceived into entering gas chambers where cyanide-based pesticide Zyklon B was released, killing those inside. Their bodies were then burned in the camp's many crematoria.
