He did, however, determine that platinum made a much better burner than carbon.Working with platinum, Edison obtained his first patent in April of 1879 on a relatively impractical lamp, but he continued searching for an element that could be heated efficiently and economically.The captured gas is currently being sold, appropriately enough, to a greenhouse that grows fruit and vegetables.However it could also be used to make fizzy drinks and renewable fuels or stored underground.The answer was to develop a vacuum that would keep air away from the elements, thus preserving the light-producing materials.
