About a week ago a number of papers published a story discreditting the OccupyLSX campaign where they used thermal images to 'prove' that the majority of the tents were empty overnight.
A few days ago the campaigners rented the same thermal cameras from the same company as the papers had used to show that in fact that the thermal cameras can't see the heat given off by a person in a tent.
Here's the campaigners video (I couldn't find the orginal one made by the papers)
Anyhow, politics aside, it's interesting to see just how well the relatively cheap and cheerful tents that they appear to be using stop the radiated infra-red heat from escaping (which is why the people appear to disappear).
I was quite impressed with how good they are.
