Dead Brain Cells Dead Brain Cells Dead Brain Cells are a Canadian thrash metal band from the late 1980s. Called DBC for short, the band started in 1985 in Montreal as a small project named Final Chapter by guitar players Eddie Shahini and Gerry Ouellette, who put an ad in a magazine looking for a drummer. In 1986, former Vomit and the Zits singer Dave Javex Ray-O-Vac (David Leone) and former Unruled and Vomit and the Zits drummer Jeff Saint-Louis, joined with Shahini and Ouellette and guitar player Phil Dakin, who switched to bass. The project grew into a serious band which took
Electrically powered spacecraft propulsion Electrically powered spacecraft propulsion An electrically-powered spacecraft propulsion system uses electrical energy to change the velocity of a spacecraft. Most of these kinds of spacecraft propulsion systems work by electrically expelling propellant (reaction mass) at high speed, but electrodynamic tethers work by interacting with a planet's magnetic field. Electric thrusters typically use much less propellant than chemical rockets because they have a higher exhaust speed (operate at a higher specific impulse) than chemical rockets. Due to limited electric power the thrust is much weaker compared to chemical rockets, but electric propulsion can provide a small thrust for a long time.
