Invisible Tank. Apparently the UK defense industry is close to launching the invisible tank they’ve been talking about for a year or more. The technology has been developed by Professor Sir John Pendry at Imperial College, London and works by beaming images of the tank’s background onto its surface using cameras and projectors. The Daily Mail image above is clearly a goodly Photoshop effort, but nevertheless it’s a pretty unbelievable tech to be reaching this stage, isn’t it? And they’re talking about using the idea to cloak soldiers too, using special vests. Wow.
New materials are being designed and manufactured which have an extraordinary property when exposed to a beam of light. Instead of light bending through them as it does in natural materials like glass and water, it bends the wrong way. It has the potential to make object invisible. This is the stuff of fantasy novels like the Harry Potter series, but how does it work and what new industries might be founded? The new materials also provide the basis for a perfect lens: one that can focus more precisely than the wavelength of light itself.
