Imagine installing an air conditioner that won’t send your summertime power bills skyrocketing. That’s the promise of new quantum dot infused windows. These tiny specks of semiconductor will enable windows to capture solar energy and generate clean power while remaining perfectly transparent. Scientists call them a “game-changer” in the future of sustainable cities.
Scientists at Columbia University have shown that changes in atmospheric humidity can actually be used to generate minor amounts of electricity – enough to power small gadgets like children’s toys or environmental sensors. The system relies on bacterial spores that swell and shrink in response to changes in moisture. Adhering these spores to a polymer sheet produces what amounts to an artificial muscle that expands and contracts, much like animal muscle, as the moisture in its environment is cycled.
That question is one of the major challenges facing proponents of fusion energy. Fusion power generation attempts to mimic the processes occurring in center of stars by heating atoms to incredibly high temperatures and pressures such that they slam together with enough force to fuse, thereby releasing energy. The problem is that the temperature required to achieve such a reaction is on the order of 150 million degrees Celsius, ten times hotter than the center of the sun and a heat level that no material on Earth can withstand.
