The document describes Andy's new designs for vehicles that significantly improve fuel efficiency and reduce emissions compared to current designs. Andy's bike design uses 1/3 the fuel and emits 1/6 the CO2 while achieving double the speed. His car and truck designs also use less fuel, produce fewer emissions, and have higher fuel efficiency and speeds than current designs. The document also briefly outlines Andy's new sea vehicle design with a single axle and front steering and rear propulsion without rear wheels. Andy's engine can use all fuels and is smaller than current engines but provides comparable power output. Production of Andy's vehicles is estimated to require investments of $30-100 million but yield profits of $150-200 million.
