GE Global Research engineers built this demonstration to show the power of nonthermal plasma. Scientists in the Aero-Thermal & Mechanical Systems lab generate a “cold” plasma inside the clear box on the right using high voltage, low current electricity.
Smoke inside the box is pumped out through the vent in the middle when the electricity breaks the surrounding air into ions, which creates flow. This system transforms electrical to mechanical energy while using no moving parts.
The team investigates nonthermal plasma technology to assist engine combustion by improving fuel burn and performance.
This ultra-efficient water-jet cutter can blast through slabs of metal with ease. Engineers at GE Global Research in Niskayuna, N.Y., are investigating the computer-guided advanced milling tool for use in several industries. Here, the water jet is being tested to cut wind turbine parts from a solid aluminum ingot.
Firing an abrasive mixture of garnet dust and plain water at a pressure of 60,000 pounds per square inch, the water-jet cutter could dramatically reduce manufacturing time at GE plants.
