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.
At $12,000, almost anyone can afford a new one. So, since the Smart Car ForTwo has a fuel tank capacity (including a 1.3 gallon reserve) of 8.7 gallons, and the Smart Car Gas Mileage (MPG) is around 40 miles per gallon, you can squeeze out about 350 miles before your next petrol visit (trying to sound British).
