[White Earth Land Recovery Project, Route 1, Box 291, Ponsford, MN 56575, (218) 573-3448, fax: (218) 573-3444] 1000 miles per gallon The Micro joule, a car built at a French school and piloted by a 10-year old driver, set a new world fuel-efficiency record at Britain's Sliverstone Raceway Microjoule traveled ten miles on a couple of spoonfuls of gasoline -- the equivalent of nearly 1000 miles-per-gallon.

Under the Navy program, Raydiance has designed and demonstrated a USP laser that generates 56 microjoules per pulse with pulses 700 femtoseconds long, a world record (a femtosecond is one billionth of one millionth of a second).
