A biodegradable plant protein can be crushed to directly generate electricity.
California will harvest freeways for electricity.
Researchers from Columbia Engineering and the Georgia Institute of Technology report the first experimental proof of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2). This makes it the thinnest electrical generator in the world. The resulting generator is optically transparent, extremely light weight, as well as very bendable and stretchable. In the future, such generators could be used to power extremely tiny devices harnessing energy from the environment, be them remote sensors or nanotech that travels through your bloodstream.
With just one footstep, you can illuminate a thousand LED bulbs – with no batteries or power cord; the energy comes from rubbing two different materials together to create static electricity. A researcher called Zhong Lin Wang has finally learned how to harvest this power and put it to work. Triboelectricity? What’s that ?! A professor at the Georgia Institute
The amazing properties of graphene are being put to use more and more, as Evan Reed and Mitchell Ong from the Stanford School of Engineering have described a new way of engineering piezoelectrics into graphene. The study was published in the ACS Nano Journal. When you apply a mechanical stress to certain materials, such as crystals, ceramics, or even biological
