Nayar, Computer Science Professor at Columbia Engineering, has invented a prototype video camera that is the first to be fully self-powered -- it can produce an image each second, indefinitely, of a well-lit indoor scene. They designed a pixel that can not only measure incident light but also convert the incident light into electric power.
