In 1972, at a formal hearing of the U.S. Senate Commerce Committee, Starr presented a vision for the Electric Power Research Institute to serve Congress's mandate for objective, scientific research. [3] Starr served as the first President of EPRI for five years and formally retired at age 65, but continued to work at EPRI for the next 30 years. [4]
Quick Take: List of Scam Area Codes. More than 300 area codes exist in the United States alone which is a target-rich environment for phone scammers.
Plasmadynamics and Electric Propulsion Laboratory (PEPL) is a University of Michigan laboratory facility for electric propulsion and plasma application research. The primary goals of PEPL are to increase efficiency of electric propulsion systems, understand integration issues of plasma thrusters with spacecraft, and to identify non-propulsion applications of electric propulsion technology.
Another type of fraud occurs when a scammer calls a utility customer and offers a rebate if the customer makes a payment or gives out personal information. These are red flags, experts say. [3] Some scam artists can disguise their phone number to make it look as though the real utility company is calling.
Electrogravitics had its origins in experiments started in 1921 by Thomas Townsend Brown (who coined the name) while he was in high school. He discovered an unusual effect while experimenting with a Coolidge tube, a type of X-ray vacuum tube where, if he placed on a balance scale with the tube's positive electrode facing up, the tube's mass seemed to decrease; when facing down, the tube's mass ...

6 kW Hall thruster in operation at the NASA Jet Propulsion Laboratory 3D sketch of an electromagnetic propulsion fusion plasma thruster. Spacecraft electric propulsion (or just electric propulsion) is a type of spacecraft propulsion technique that uses electrostatic or electromagnetic fields to accelerate mass to high speed and thus generating thrust to modify the velocity of a spacecraft in ...
The VASIMR method for heating plasma was originally developed during nuclear fusion research. VASIMR is intended to bridge the gap between high thrust, low specific impulse chemical rockets and low thrust, high specific impulse electric propulsion, but has not yet demonstrated high thrust.
