Singapore's solar-powered ''supertrees''

July 21, 2012 — It's no secret that trees are good for the environment. But if you don't have enough, you can always build more!

A 350-acre landscaping project in Singapore is using technology to reduce carbon emissions and improve air quality.

"Supertrees" made out of a mixture of concrete and steel act as a base for ferns, flowers and other climbing plants.

"Trees trap energy from the sun. Our supertrees do the same with photovoltaic cells on the top," explains Kiat W. Tan, CEO of Singapore's Gardens by the Bay.

Tan says that the area has seen an increased presence of birds and aquatic life now that the park has been built.

The trees are one of the flagship attractions in the Gardens by the Bay development, a massive public space that also includes sprawling lakes, bridges and a climate-controlled flower dome.
