IN THE SHADE OF A SOLAR TREE
There are plenty of real trees around. Oaks, pines and willows line the trails that circle
through the nature park near Mount Carmel in northern Israel. 5.1. _____ Just like real trees,
it obtains energy from the sun and its brown metal branches reach high toward the sky, like
the acacia tree this model is named after. Its seven broad “leaves” are standard solar panels.
They shade benches below, power electric and USB outlets and supply energy for wi-fi.
Inventor Michael Larry says it’s a new way of bringing solar power to people. “We’re used
to seeing big companies working on large scale systems,” he says. “Now we see solar energy
becoming accessible to each one of us on the street.” The tree was formally unveiled on
Thursday, although it was installed in the park several weeks ago. All the experts invited to
the ribbon-cutting ceremony carefully examined it to find out what uses it may have. 5.2. _____.
This particular feature was unanimously acclaimed as its main advantage.
It has been stressed that smart cities are the future of the world. This tree, indeed, has
the potential to become the icon of the city which has planted it. 5.3. _____ That is why,
the Israeli company that dreamed up the tree is already targeting major metropolises in China
and Europe for first sales.
A seven-panel tree can generate enough energy to run 35 laptops. A battery stores excess
power, lighting the area at night and providing backup power on cloudy days. The tree is
an excellent idea for young people away from home who go to the park and want to charge their
phone. However, the solar tree has its limits. 5.4. _____ The designer of the solar acacia admits
the project needs improvement. “We’ll see how it catches on worldwide and then further steps
will be taken,” he declares.
