Is work becoming obsolete? Will Americans learn to love their leisure time? As the spotlight focuses on AI and its various implementations, former Harvard Professor Jeffrey Sachs, now at Columbia University and a special adviser to the United Nations, has some strong and diverse opinions about the macroeconomic impact of robots on the role of work in the future.

At a Mar. 24 seminar hosted by MIT IDE — the same day Treasury Secretary Steven Mnuchin amazed the tech community by saying AI wasn’t even on his radar — Sachs described AI developments as a “huge” with implications as vast as any previous seismic technology wave. “We are in the midst of a major transformation” that will fundamentally change civilization from the past, he said.

It takes millions of years for natural processes to convert plants into gasoline, but researchers at Ghent University have figured out how to do it much faster. By pre-treating grass to make it break down quicker, and then adding Clostridium bacteria similar to that found in your gut, they produced decane, one of the main ingredients of gasoline and jet fuel. While decane is a polluting fuel, commercial jets will need it for at least the next few decades, and the researchers believe their process is efficient enough to make it commercially feasible.

For their system to work, the scientists first treated the grass with a compound that broke it down and made it easier for bacteria to digest. They then treated it with an enriched Clostridium bacteria from the family that makes up the good bacteria in your gut, rather than the one that kills you. Fermentation much like that used for beer produced lactic acid and its derivatives, and further treatment yielded caproic acids. With further processing, that was converted into decane, a primary ingredient of gasoline and jet fuel.

As mentioned, decane and similar products aren’t very clean fuels (they produce CO2 when burned), but they still have a much higher energy density than, say, lithium batteries. As such, be the main fuel used in aviation for the foreseeable future, as jet planes need to be relatively light to get aloft.

Its six compact jet engines will send you hurtling through the sky at 100 mph.


The media is bursting at its seams with what seems to be the superhero revolution. Comic book publishers like Marvel and DC have spilled over onto the big screen, and now it may look as though they’re spilling over into our technology in the real world. While we have been making efforts at a superhero heads up display or an iron man workout suit, we are also inching our way up to a functional flight suit.

Gravity is a British technology start-up started by Richard Browning on March 31, 2017. The company has developed a human propulsion system to re-imagine manned flight. With miniaturized jet engines and a customized exoskeleton, the Daedalus is expected to push us into a new era of aviation. Browning and his team developed the suit over the course of 2016, with the team’s journey covered in this short documentary:
