Solar-powered trees are planted in Israel to charge phones, cool water, and offer Wi-Fi

All trees convert sunlight into chemical energy, but now there are trees that convert sunlight into power to charge devices, cool water, offer free Wi-Fi and more for the benefit of their surrounding communities. Thanks to an imaginative idea from an Israeli company called Sologic, solar-powered trees are taking root to raise environmental awareness while providing green energy.

The eTree comprises a metal trunk that branches out to support solar panels instead of leaves. The structure, which looks like a pixelated tree in an 8-bit video game, uses the energy captured by the solar panels to provide USB charging outlets for smartphones and tablets, free Wi-Fi, a water trough for pets, a drinking-water fountain for humans, nighttime lighting and informational LCD screens.

“We’re used to seeing big companies working on large-scale systems,” says Michael Lasry, founder of Sologic. “Now we see solar energy becoming accessible to each one of us on the street.”

The first eTrees were unveiled Thursday at the HaNadiv Gardens near Zikhron Ya’akov in Israel. Sologic has plans to sell more of these solar-powered trees in China and France.

One Acacia model eTree (the kind planted in Israel) costs about $100,000. A seven-panel version can generate up to 1.4 kilowatts, which is enough to run 35 laptops.

The big price tag means the eTree probably won’t replace traditional rooftop solar panels, but it has a chance at becoming a popular eye-pleasing fixture in parks across the globe, according to Eli Barnea, an investor in Israel’s largest private power company.

Sologic foresees future eTrees utilizing cameras along with touchscreen displays to enable someone standing beneath one solar-powered tree to say hello to someone else standing beneath another eTree planted anywhere in the world.

The Apollo wearable is proven to help you sleep better (and it’s on sale)

Stress, anxiety, and insomnia are all concerning things that just about everyone struggles with at one time or another. Maybe you can sleep, fending off insomnia, but you lack quality sleep and don’t feel rested in the morning. Or, maybe when it’s time to kick back and relax, you just can’t find a way to do so. There are many solutions for these issues, some work, and others don’t, but one unlikely area of support can be found in a modern, smart wearable.

Medicine is the obvious choice, but not everyone prefers to go that route. There is an answer in modern technology or rather a modern wearable device. One such device is the Apollo wearable, which improves sleep and stress relief via touch therapy. According to Apollo Neuro, the company behind the device, which is worn on your ankle, wrist or clipped to your clothing, it sends out waves of vibrations to help your body relax and reduce feelings of stress. It's an interesting new approach to a common problem that has typically been resolved via medicine, therapy, or other more invasive and time-consuming techniques. The way it utilizes those vibrations, uniquely placed and administered, to create a sense of peace, makes us ask, can it really cure what ails us? We’ll dig a little deeper into how it achieves what it does and what methods it’s using to make you feel better.

What comes after Webb? NASA’s next-generation planet-hunting telescope

An illustration shows how NASA's Habitable Worlds Observatory would measure the atmosphere of distant planets.

When it comes to building enormous, complex space telescopes, agencies like NASA have to plan far in advance. Even though the James Webb Space Telescope only launched recently, astronomers are already busy thinking about what will come after Webb — and they've got ambitious plans.

The big plan for the next decades of astronomy research is to find habitable planets, and maybe even to search for signs of life beyond Earth. That's the lofty goal of the Habitable Worlds Observatory, a space telescope currently in the planning phase that is aimed at discovering 25 Earth-like planets around sun-like stars.
