The Ray Sphere was a device used by transferring the neuro-electric energy from a group of people to concentrate it into a human indevidual to unlock his/her powers. Though it will unlock the dormant abilities of the Conduit, it will kill the catalysts, and worse, cause a catastrophic explosion.
How many gallons of gas does the average mid-size car hold? The average fuel tank size for mid-size cars is 16 gallons. If the  price of gas was $3.59 per gallon, it would cost $57.44 to fill a  16 gallon tank.
My Chevy and Ford trucks have close to 30 gallons. From the research I've done, it all depends on the car(s) size. It seems that smaller cars are able to hold 12 gallons worth of gas in a car tank, but for those who are driving larger cars then it'll be around 15-16 gallons worth of gas in a car tank.
