Israeli eTreePhoto Credit: gajitz.comA solar-powered tree is a type of solar-powered charging station that can capture solar energy and provide free electricity from the sun to public places.
In 2010, a group of students In Belgrade, Serbia developed the first solar-powered tree in the world - the Strawberry Tree. This is the first public solar charger for mobile devices. The innovative solar charging station has Wi-Fi, USB ports and 16 chargers for various types of mobile phones and other portable electronic devices. The Strawberry Tree won first place in the European Commission’s "Sustainable energy week 2011" competition in Brussels, in the category “Consuming”.
Another example of a high-tech futuristic solar-powered tree is eTree created by the Israel-based company Sologic. This “tree” is a place to take a break while recharging your mobile gadgets and accessing the Internet via free Wi-Fi. Similar to a real tree, the eTree has brown trunk and branches. But, instead of having leaves, there are solar panels that are angled towards the sky. The eTree has USB ports and provides a small amount of lighting during the night. There are also benches located beside the solar-powered tree. The first eTree was installed at a nature reserve in Israel.
Solar-powered palm is a variation of a solar-powered tree. This stunning solar design absorbs sunlight during the day through "leaves" covered with ultra-thin solar modules and converts to an exotic solar-powered lamp at night. The trees’ energy can also be used to charge mobile devices through its integrated USB connection.
The first Smart Palm installed on Jumeirah beach in Dubai is one more example of solar-powered palm. Now, these Smart Palms, or "self-sustaining community tech hubs" are on every public beach in the city, as part of an ambitious plan to convert Dubai into a "Smart City". There are 50 solar-powered Smart Palms on public areas, and each of them provides Wi-Fi, USB socks for mobile phones and tablets, as well as updated information on the weather and local attractions. The solar-powered palm trees are illuminated at night using the system’s battery where solar energy is stored.
And finally, I should mention solar-powered supertrees, although they are not solar charging stations.

There are amazing gardens in Singapore - Singapore’s Gardens by the Bay with 18 manmade steel supertrees varying from 15 to 50 meters in height. 11 of them have solar photovoltaic systems to convert sunlight into electricity, so they can light up at night. The supertrees also function as vertical gardens, air venting towers, and rainwater collection devices. These incredible constructions are designed by Grant Associates.
The above solar-powered trees are just several examples of the beautiful innovative design, which is also a growing solar trend in the world.
