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 today in the journal Chem, scientists trying to improve the solar cells themselves developed an integrated battery that works in three different ways.

The Gallup Poll recently reported that “even before Hurricane Matthew ravaged Southern Haiti in late 2016, the small Caribbean nation was already in deep distress, with more than four in 10 Haitians (43%) rating their lives poorly enough to be considered suffering”. The only country suffering more than Haiti in the world is South Sudan where famine already has been declared in two counties of South Sudan, and 1 million people there are on the brink of dying from a lack of food. Hurricane Matthew struck Haiti last October; according to the U.N. Office for the Coordination of Humanitarian Affairs, the storm left nearly 140,000 Haitians homeless . . .

 . . . The hurricane took the people’s lives, homes, chickens, goats, crops, trees, schools, and churches. They had little food and water. They had no money. What was left? . . . 

 . . . a plea for us to find humanity again.  With compassion, followed by action, we would create resilient societies which care for one another.
