Once Around the Web: Past and Future Construction

Ah, remember when Bertha was working? Those were good times. But tunneling is hard work and sometimes things go wrong. Currently the plan is to have Bertha back on the dig by March 2015 and until then you can follow along via Twitter. They share some pretty cool pictures of the repair progress. Take for example, this one from about a week ago:


If looking through Bertha’s archives doesn’t satisfy your need for cool photos of tunneling machines, you should check out this article over at Gizmodo!

So cool right? Looks like a steampunk dinosaur! Speaking of cool, you’ve seen this video about solar roadways right?

The internet is a buzz with the idea of solar roadways – they pay for themselves, they create jobs, they melt snow, they cut greenhouse gas emissions, they can display dynamic messaging and road striping, and they can do the cha cha! Ok, not that last one but thanks to a federal grant from the FHA, a working prototype exists and it’s blowing a lot of minds. So much so, that their indiegogo campaign has already raised more than 2 million dollars!
