Construction Tech of the Week | littleBits, the Legos of the Future

Since their invention, over 400 billion Lego blocks have been produced, allowing non-engineers, non-architects, and non-commercial-builders around the world create the structures from their imaginations. Just like Legos prove that building isn't only for those who can move concrete bricks, TED fellow Ayah Bdeir refuses to accept that the "building block of our time, the transistor, is reserved for experts."

As founder of littleBits, Bdeir aims to put the power of engineers in the hands of artists, designers, students, and even children.

"littleBits are a set of simple, interchangeable blocks that make programming as simple and important a part of creativity as snapping blocks together. It's an opensource library of electronic modules that snap together with tiny magnets for prototyping and play."

Each bit is an electronic module with a specific function, indicated by its color. By snapping them together, the builder controls functions like power and light output just like a programmer. Electronic programming can be understood and executed by those who otherwise have no knowledge of wires and transistors.

Construction Tech of the Week | SmartBidNet | Green Concrete

Researchers at Auburn University and the University of Alabama are working on a new recipe for concrete. The recipe calls for coal ash - a power plant by-product - instead of cement and a futuristic ingredient called carbon nanotubes. "The nanotubes, which add strength, durability and conducting properties to the concrete, are produced by cooking an iron compound for 10 seconds in a microwave." 

"It is very much like you cook popcorn," a researcher said.

The electricity conducting nanotubes could mean speeding up the melting of ice on bridges or runways and reusing coal ash could mean less being dumped in bodies of water and landfills.

The new concrete recipe is still in the research and development phase. If proven that the use of ash and nanotubes won't be harmful to the environment in other ways, the 70% of concrete construction materials used globally might be in for a big change...
