Here's how to make everyone think about volunteering.
The average person has 4 hours of leisure time per day. How is your #nonprofit enticing the busiest of people to #volunteer? http://ow.ly/wWDg30mfHIi

Solar energy is the way to the future.
Solar energy is becoming more and more popular as prices drop, yet a home powered by the Sun isn’t free from the grid because solar panels don’t store energy for later. Now, researchers have refined a device that can both harvest and store solar energy, and they hope it will one day bring electricity to rural and underdeveloped areas.
The problem of energy storage has led to many creative solutions, like giant batteries.
For a paper published in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways. It can work like a normal solar cell by converting sunlight to electricity immediately, explains study author Song Jin, a chemist at the University of Wisconsin at Madison. It can store the solar energy, or it can simply be charged like a normal battery.

It’s a combination of two existing technologies: solar cells that harvest light, and a so-called flow battery. The most commonly used batteries, lithium-ion, store energy in solid materials, like various metals.
Flow batteries, on the other hand, store energy in external liquid tanks.
This means they are very easy to scale for large projects. Scaling up all the components of a lithium-ion battery might throw off the engineering, but for flow batteries, you just make the tank bigger says Timothy Cook a University at Buffalo chemist and flow battery expert not involved in the study.
You really simplify how to make the battery grow in capacity he adds. We’re not making flow batteries to power a cell phone, we’re thinking about buildings or industrial sites.
Jin and his team were the first to combine the two features. They have been working on the battery for years, and have now reached 14.1 percent efficiency.
Jin calls this round-trip efficiency as in, the efficiency from taking that energy, storing it, and discharging it.
We can probably get to 20 percent efficiency in the next few years, and I think 25 percent round-trip is not out of the question Jin says.

Apart from improving efficiency, Jin and his team want to develop a better design that can use cheaper materials. The invention is still at proof-of-concept stage, but he thinks it could have a large impact in less-developed areas without power grids and proper infrastructure.
There, you could have a medium-scale device like this operate by itself he says. It could harvest in the daytime, provide electricity in the evening.
In many areas, Jin adds, having electricity is a game changer, because it can help people be more connected or enable more clinics to be open and therefore improve health care.
And Cook notes that if the solar flow battery can be scaled, it can still be helpful in the US. The United States might have plenty of power infrastructure, but with such a device, “you can disconnect and have personalized energy where you’re storing and using what you need locally,” he says. And that could help us be less dependent on forms of energy that harm the environment.

Yes, exactly - why?
