Comments Off on MIT unveils new solar 3D printer that can build houses on other planets

Some people dismissed 3D-printing in its early days as a novelty, but these days the technology is coming into its own and researchers at MIT have just taken it to the next level. They’ve created a robot that can print the entire basic structure of a building. This is particularly exciting because it could change the way we construct buildings, making the process faster and less costly. Using the new technology, a builder could customize a structure to fit the desires and site requirements of any space. Along with allowing for a wider variety of materials and a variation in material density, it could mean that someday we can construct buildings that we wouldn’t be able to today using traditional methods.

The truck also has a scoop, so that the truck can help prepare the building area and pick up building materials on its own, meaning you could create rammed-earth walls using on-site materials with the same system that you use to print the structure. MIT says the system can be powered electrically with solar panels, which means it could be used in remote areas or even on other planets. MIT showed the technology off by building a 12-foot high, 50-foot wide dome out of foam-insulation framework. The entire structure was completed in just 14 hours. “The construction industry is still mostly doing things the way it has for hundreds of years,” said engineering graduate Steven Keating, who worked on the project. This robot is intended to move things into the future. + MIT

Comments Off on This bike lane in Korea is topped with 20 miles of solar panels

Is this the greenest road ever? A highway in Korea features a stunning solar-powered bike lane running right down the middle. The lane is offset, protected by barriers, and sheltered by solar panels. The lane runs from Daejeon to Sejong, a distance of around 20 miles (32 km), which is a few hours’ drive from the capital city Seoul. It’s a fantastic idea that could pave the way for similar commuting-style bike lanes in the future. + Janbaz Salehi
