dryriver writes: Brian Harper, who helped develop early thermal imaging tech for the military almost 50 years ago, uses infrared imaging to make visible to people their energy usage and carbon footprint. From the BBC: "Brian Harper is not happy with the state of my house. As he pulls up the corner of my bathroom carpet, he cries out when he sees what is beneath: a section of missing floorboard. On a tablet showing live thermal image video, the resulting cold patch is dark violet. Harper is assessing the energy efficiency of my home. And apparently, it is sub-par. Cutting the energy we use in our homes is vital if societies are going to reduce global emissions from fossil fuels. Technological advances in renewable sources will help, but they still are unlikely to provide all the answers. Which explains why Harper, who helped develop early thermal imaging tech for the military almost 50 years ago, is poking about behind the lavatory of my semi-detached Victorian home in Bristol. His reaction to my missing floorboard and seeing the heat loss on screen underscores the potential connections between my chilly, poorly insulated room and our large gas bills."
