that can extract energy from the environment to recharge. Last week, at the Symposia on VLSI Technology And circuits, MIT researchers presented a new power converter chip that can harvest more than 80 percent of the energy trickling into it

#Nanogenerator harvests power from rolling tires A group of University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car's rolling tire friction.
An innovative method of reusing energy, the nanogenerator ultimately could provide automobile manufacturers a new way to squeeze greater efficiency out of their vehicles.
which is the first of its kind, in a paper published May 6, 2015, in the journal Nano Energy("Single-electrode triboelectric nanogenerator for scavenging friction energy from rolling tires").
Xudong Wang has developed a new way to harvest energy from rolling tires. The nanogenerator relies on the triboelectric effect to harness energy from the changing electric potential between the pavement and a vehicle's wheels.
The triboelectric effect is the electric charge that results from the contact or rubbing together of two dissimilar objects.
Wang says the nanogenerator provides an excellent way to take advantage of energy that is usually lost due to friction."
"That energy is wasted. So if we can convert that energy, it could give us very good improvement in fuel efficiency."
"The nanogenerator relies on an electrode integrated into a segment of the tire. When this part of the tire surface comes into contact with the ground,
The movement of electrons caused by friction was able to generate enough energy to power the lights
supporting the idea that energy lost to friction can actually be collected and reused.""Regardless of the energy being wasted,
we can reclaim it, and this makes things more efficient, "Wang says.""I think that's the most exciting part of this,
how to save the energy from consumption.""The researchers also determined that the amount of energy harnessed is directly related to the weight of a car,
as well as its speed. Therefore the amount of energy saved can vary depending on the vehicle -but Wang estimates about a 10-percent increase in the average vehicle's gas mileage given 50-percent friction energy conversion efficiency."
"There's big potential with this type of energy, "Wang says.""I think the impact could be huge."

So-called high-energy states in enzymes are regarded as necessary for catalysing of chemical reactions. A high-energy level is a protein structure only occurring temporarily and for a short period of time;
and these factors collaborate until its state becomes invisible to traditional spectroscopic techniques. The Ume researchers have managed to find a way to maintain a high-energy state in the enzyme, adenylate kinase,
