#Germany and Canada Are Building Water Splitters to Store Energy Germany which has come to rely heavily on wind
and solar power in recent years is launching more than 20 demonstration projects that involve storing energy by splitting water into hydrogen gas and oxygen.
It can be deployed almost anywhere it can store vast amounts of energy and the hydrogen can be used to replace fossil fuels not only in electricity production but also in industry and transportation
Even so it has long been considered a relatively lousy way to store energy because of its low efficiency about 65 percent of the energy in the original electricity is lost.
When it opens next year it will have the capacity to produce 650000 kilograms of hydrogen a year the energy equivalent of 650000 gallons of gasoline.
It s also more versatile than the cheapest way to store energy: pumping water up a hill
So an important question is how to minimize the energy it takes to grow these crops.

#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."

early supporters of the project will gain exclusive first-issue access to the case, which doesn't so much charge an iphone actively as it does extend its normal battery life.
what stands to inspire a new generation to take advantage of energy inefficiency and waste. One major drawback to the technology is that its relatively slow to harvest energy,
and the case itself doesn't contain an actual battery of its own to store excess charge.
"Tesla's visions of wireless energy threatened the military-industrial complex; were sabotaged his ideas? The official Kickstarter campaign for the case is expected to be launched in June,
and its unveiling is sure to inspire many curious folks to take a closer look at the energy discoveries of the man behind the Nikola name, Nikola Tesla.
Of particular interest was Tesla's dream of developing a way to transmit energy wirelessly using only air as a medium.

"At the moment, we're not talking about producing large volumes of energy, "says Netzer.""But the process is very interesting

In the future such technology could help harvest otherwise wasted energy to squeeze just that extra bit of efficiency out of cars and other vehicles.
The nanogenerator harvests the wasted tire friction energy by relying on the triboelectric effect. It is the electric charge that results from the contact or rubbing together of two dissimilar objects.
The generator harnesses energy from the changing electric potential between the pavement and a vehicle wheels.
Scientists said that it could become a very useful way to use the energy that is usually wasted due to friction taking advantage of this lost energy would improve efficiency,
since that energy is wasted simply, f we can convert that energy, it could give us very good improvement in fuel efficiency Improving fuel efficiency would benefit everyone it would help automotive industry meet new strict regulations for emissions,
make traveling just that little bit cheaper and would improve energy efficiency which would benefit environmental causes as well.
The friction was strong enough for the electrodes to harvest enough energy to power the lights,
which means that scientists confirmed the idea that wasted friction energy can be collected and reused.
Engineers also determined that the amount of energy harnessed is directly related to the weight of a car
It means that different vehicles would waste different amounts of energy and different percentage of it could be saved using this method.
This is always largely about collecting wasted energy. That is why this technology has a huge potential
