Transport on water
Dwarka Prasad uses large specially designed shoes filled with thermocol, fitted to each foot, and oars filled with thermocol to walk on water using buoyancy principles. Use of lightweight thermocol gives the desired buoyancy. The shoes for walking on water consist of two floats made of thermocol, bonded to rexine sheet. This whole unit is attached to metal straps with back foot support. These two individual shoes are also tied to each other to prevent them from going too far apart beyond one?s ability to steer or navigate them. One needs a pair of hand held oars for balancing while walking in water.Nationally, there are very few alternatives for crossing water bodies except boats. Amphibious bicycles are one among them which use buoyancy principles, using an air filled float and propeller in rear wheels. For water shoe systems, most of the alternatives available abroad including Wetfoot-trainer and rescue, upright human prolusion apparatus and Water walker, etc.,financial help from anyone and refused help from others even to buy his medicines. Today when he is in the evening of his life, one can see the sparkle in his eyes on the mention of what was his next goal. He can not help smile and assert, " bas ab English channel paar karni hai" ( now, I have to cross English channel).
Link: work on the principle of propulsion while the shoes developed by Dwarka Prasad work on the principle of buoyancy, which results in lesser complexity, parts and weight, with no fuel requirement.His life has been a life of constant turmoil and struggle. But the faith in God and tremendous support from his wife kept him going through out. Since the demise of his wife few years ago, he has been left alone as she was his pillar of strength; the very mention of her brings tears to his eyes.The spirit of innovation and the desire to achieve his goals kept on pushing him to the edge of his physical, emotional and financial capabilities. A man of tremendous self-respect, he never sought any
