University of Sheffield scientists developed a way to produce perovskite solar cells using a spray-paint process. This process could lead to a reduction in the cost of solar electricity.

Engineers at the University of Washington developed a communication system that uses RF signals to power battery-free wireless devices through existing Wi-Fi infrastructures. This new system could propel the future of Internet of Things.

A new engine developed by NASA could lead to a breakthrough in the future of space exploration. The engine defined as a microwave thruster system operates using concentrated microwaves that bounce in a small, enclosed vessel. No other source of fuel is required.
