New flow battery stores power in simple organic compound

Flow batteries are not very different from the everyday batteries that we use. The big difference is that the energy is stored in two separate...

This battery-free wireless device could float in the wind like dandelion seeds

Wireless sensors can monitor how temperature, humidity or other environmental conditions vary across large swaths of land, such as farms or forests. These tools could...

How to clean solar panels without water

Solar power is expected to reach 10 percent of global power generation by the year 2030, and much of that is likely to be...

Researchers find new way to improve solid-state batteries

In the endless quest to pack more energy into batteries without increasing their weight or volume, one especially promising technology is the solid-state battery. In...

Scientists find better way to calculate fuel efficiency for dolphins

Researchers use noninvasive movement tags and a device that measures oxygen consumption to assess how much energy a dolphin uses while swimming. From foraging for...

Stanford AI deciphers atomic-scale images for better batteries

Today’s rechargeable batteries are a wonder, but far from perfect. Eventually, they all wear out, begetting expensive replacements and recycling. “But what if batteries were indestructible?”...

Why can’t we get our drinking water from the ocean?

For centuries, people have been trying to divine freshwater from the ocean. Ships in the 16th century carried small distilleries that could be used in...

Scientists find new electrolyte for solid-state lithium-ion batteries

New battery material offers promise for the development of all-solid batteries. In the quest for the perfect battery, scientists have two primary goals: create a...

New catalyst could turn carbon dioxide into gasoline 1,000 times more efficiently

Engineers working to reverse the proliferation of greenhouse gases know that in addition to reducing carbon dioxide emissions we will also need to remove...

Cornell researchers reveal cause of key sodium-ion battery flaw

Scientists have uncovered the source of a persistent problem limiting the durability of sodium-ion batteries. This provides manufacturers with new strategies for powering the 21st...
