Kitchen Microwave Inspires Prototype Space Propulsion System

A prototype propulsion system powered by a kitchen microwave has the potential to reduce propellant needed by up to 50%, enabling longer satellite lifespans and cost savings. The microwave-powered thruster operates more efficiently than chemical systems and is safer, as it only produces thrust when microwaves are active.

Cooking And Salad Oils Could Lubricate Cars, Boats, Machines

Researchers at Penn State have discovered that certain vegetable oil formulations can perform as well or better than commercial standards in tests for high-temperature resistance, slipperiness, and evaporation loss. This breakthrough has the potential to provide a more environmentally friendly alternative to traditional lubricants.
