How a New Tandem Solar Cell is at the Forefront of Solar Innovation
The cost of solar power is beginning to reach price parity with cheaper fossil fuel-based electricity in many parts of the world, yet the clean energy source still accounts for slightly more…
4D Printing: 3-D printed structures “remember” their shapes
Engineers from MIT and Singapore University of Technology and Design (SUTD) are using light to print three-dimensional structures that “remember” their original shapes. Even after being stretched, twisted, and bent at extreme…
Sponge creates Steam using ambient sunlight without requiring Mirrors or Lenses
Harvesting solar energy as heat has many applications, such as power generation, residential water heating, desalination, distillation and wastewater treatment. However, the solar flux is diffuse, and often requires optical concentration, a…
MIT’s Programmable Network Routers enable Flexible Traffic Management, without sacrificing Speed
Like all data networks, the networks that connect servers in giant server farms, or servers and workstations in large organizations, are prone to congestion. When network traffic is heavy, packets of data…
