We also looked at several incredible (and insane) futuristic modes of transportation - for starters, how about an electric zip-line backpack that shoots you through city streets? We were also impressed by the Cell, a shape-shifting electric vehicle concept that comes complete with its own car-sharing transit system. And if soaring through the skies is more your style, check out these self-sufficient airships that harness solar energy to generate biofuel.
Wearable tech saw several developments as well - this week we looked at the ultra-efficient 3d printers that created Iron Man's suit of armor. In other news, your next trip to the doctor could merit more than a single shot in the arm - researchers are developing a new type of "prescription" tattoo that keeps tabs on glucose levels using infra-red ink.
Finally, we saw several remarkable inventions that stand to change how we combat climate change and construct our built environment. This week Bill Gates unveiled plans to invest in the development of a fleet of seawater-spraying mist machines that could combat climate change by creating sunlight-reflecting clouds, and we looked at a new type of biologically crafted brick that can be "grown" from a combination of sand, bacteria, and urine.
