Invent Now 2006 Modern Marvel of the Year:
The Strawjet is a farm implement that processes straw (wheat, flax, sunflower, tobacco, hemp, etc.) in the field (after the plant has been harvested) into a mat, similar to a large bamboo window blind. This is used to construct composite building panels in much the same way as fiberglass or carbon fiber; however, the Strawjet uses a binder made from paper pulp, clay and cement rather than plastic resin.
