5 Solar Innovations That Are Revolutionizing the World
Solar power is lighting up the world, and not just on rooftops. Forward-thinking minds are discovering ways to harness the sun's energy in many exciting ways, from the ground beneath our feet to the shirt off our back. The following innovations are shining beacons in a renewable energy future.
1. Strides in solar efficiency
Most solar generators can convert up to 23 percent of sunlight into electricity. However, Swedish company Ripasso Energy claims they can covert 34 percent of the sun's energy into power with their contraption (see photo above), making it the world's most efficient solar electricity system. According to The Guardian, independent tests found that a single Ripasso dish can generate 75 to 85 zero-emission megawatt hours of electricity a year, or enough to power 24 typical homes in the UK. To compare, to create the same amount of electricity by burning coal would release roughly 81 metric tonnes of CO2 into the atmosphere, the newspaper reported.
2. Battery technology and shared solar untether us from Big Power
Elon Musk really is Tony Stark. The billionaire entrepreneur recently unveiled a revolutionary suite of Tesla batteries that he says could "fundamentally change the way the world uses energy" and get us off dirty fossil fuels. Musk's sister company SolarCity is now offering Tesla batteries at a price point that’s more than 60 percent less than previous solar power storage products, paving the way for more people to peel themselves off the grid.
For people who don't have the funds or the right roof for photovoltaic panels, peer-to-peer solar startup Yeloha is offering a genius solution: solar sharing. The company allows customers to "go solar" without owning a single panel by essentially feeding off their neighbors who do (and at a price that’s less than what they’d normally pay to their utility).
3. Portable solar brings light to developing world
For places recovering from disaster or communities lacking access to electricity, solar systems provide an alternative or a complement to traditional power sources such as fossil fuel generators (diesel or gasoline is not only expensive, it emits noxious fumes and can cause fires). For example, after the first of two devastating earthquakes struck Nepal, solar company Gham Power deployed solar power systems to help power lights and mobile charging stations for relief workers and the displaced. And in Haiti, the nonprofit organization Field Ready is trying to use a solar powered 3D-printer to make a whole range of simple, life-saving medical supplies at a fraction of the cost.
4. Solar desalination: solution to drought?
Scientists are solving the planet’s fresh water worries with a little help from the sun. Recently, a team from the Massachusetts Institute of Technology and Jain Irrigation Systems have come up with a method of turning brackish water into drinking water with a solar-powered machine that can pull salt out of water. It then further disinfects the water with ultraviolet rays. With parts of the planet running perilously low on fresh water, realization of this technology can’t come soon enough.
5. Solar transportation
In the air and on the road, solar technology is going the distance. Currently, the Solar Impulse 2, the first solar airplane able to sustain flight at night with a pilot on board, is making its historic round-the-world trip powered only by the sun.
Over in the Netherlands, SolaRoad, the world’s first “solar road,” has defied expectations and has generated about 3,000 kWh of power, enough to provide a single-person household with electricity for a year. Considering it's only a 230-feet bike path, the potential for this technology could be big, kind of like photovoltaic technology itself.

If you had to choose a diamond for your engagement ring from below or above the ground, which would you pick … and why would you pick it? This is the main question consumers are facing when picking out their diamond engagement ring today. With a dramatic increase in demand for conflict-free lab-grown diamonds, the diamond industry is shifting right before our eyes.

The Pacific Island nation of Samoa declared a state of emergency this week, closed all of its schools and limited the number of public gatherings allowed after a measles outbreak has swept across the country of just 200,000 people, according to Reuters.

Rising above the Arizona desert, the Santa Rita Mountains cradle 10,000 years of Indigenous history. The Tohono O'odham Nation, Pascua Yaqui Tribe, and Hopi Tribe, among numerous other tribes, have worshipped, foraged, hunted and laid their ancestors to rest in the mountains for generations.
Native Americans are disproportionately without access to clean water, according to a new report, "Closing the Water Access Gap in the United States: A National Action Plan," to be released this afternoon, which shows that more than two million Americans do not have access to access to running water, indoor plumbing or wastewater services.

In the Czech Republic, horses have become the knights in shining armor. A study published in the Journal for Nature Conservation suggests that returning feral horses to grasslands in Podyjí National Park could help boost the numbers of several threatened butterfly species.
