Balloon Assisted Transportation
by Edward E. Rochon
Use balloons to lighten not airlift vehicles off the ground. Use engine heat to produce hot air lift. Use inflated airfoils to achieve lift for cars and ships. Use inflated airfoils as sails in some cases at sea. Use lift to allow ships and barges through waterways not otherwise deep enough. 3 in 1: heat, lighten, foil lift - to increase fuel efficiency of cars and ships, trains and barges too.
