One might imagine something as seemingly complex as carbon foam used to insulate airplanes would be made from a slurry of chemical compounds that only a materials engineer could pronounce. But, in reality, researchers from China's Harbin Institute of Technology have designed a fully functional carbon foam insulator made from bread. That's right, regular old bread.
Previous iterations of carbon foam had been designed using the technologically advanced chemicals from the imaginary scenario above, but those materials ended up being costly. By using bread for their carbon foam, Harbin IT has created an incredibly economical process for manufacturing the material.
Another benefit of the new material is its eco-friendliness: rather than synthesizing chemicals and creating byproducts that can harm the surrounding environment, there is virtually no waste associated with the Harbin Institute of Technology's foam.
