This invention describes an energy gathering system that uses a single, rollable sheet to hold many tiny hybrid devices, each capable of harnessing both wind and solar energy. These devices are less than one inch in size, with some claims specifying them in the micrometer to nanometer range. The sheet includes built-in circuits to collect the energy from these devices and convert it into storable electricity.
Why it matters: In 2007, fabricating efficient, integrated hybrid wind-solar devices at the micrometer-to-nanometer scale on a flexible sheet was nascent. Advances in micro-fabrication and flexible electronics since then make such integrated systems more technically viable.
