Scientists invent 'transparent wood' in search for eco-friendly building material

New material could replace plastic or glass in construction of energy-efficient homes

In an era of glass and steel construction, wood may seem old-school. But now researchers say they have given timber a makeover to produce a material that is not only sturdy, but also transparent and able to store and release heat.

The researchers say the material could be used in the construction of energy-efficient homes, and that they hope to develop a biodegradable version to increase its eco-friendly credentials as an alternative to plastic, glass or even cement.
