Doesn't make that much sense, but according to the researchers at the Rensselaer Polytechnic Institute, this is a possibility. The researchers are creating a thin-film solar power technology that can stick to all kinds of surfaces, including beer bottles. This technology will be capable of shrinking solar panels to micrometer-thin tiles that could potentially replace climate-control systems, or in the most practical case: keep beer colder, longer. Works for me. Hopefully it doesn't increase the cost of beer that much, or I may be stuck drinking solar-powered Pabst Blue Ribbon. Ugh.
