Scientific American has a great article on why airships will probably not be part of our transportation infrastructure[0]. In short the energy required to move a specified payload is about the same as that of an airplane, but the payload ge

part of the reason thermal cameras are cheap and ultrasounds are not is that thermal cameras have consumer uses. One can use thermal cameras for hunting or determining home energy efficiency, an ultrasound can pretty much only be used for m

The part at 1:23 is not that impressive. It is a carefully controlled lab environment, all flat surfaces, no obstacles, with a cubical box that has carefully placed AR tags which tell of the box's exact position and orientation. Not to

The biggest problem is that we still don't understand the principles of walking, locomotion, and manipulation. Biology doesn't come with any documentation. This is much more than the problem of not having good sensors, not having

Here's a bit more on the specs of MIT's design: http://hyperloop.mit.edu/ From the lift to drag ratio(14) and cruising speed provided(110 m/s), we can compare it's performance to other forms of transport

Now the question is, how applicable are the approaches developed for AlphaGo to other tree search problems? The beating a professional Go player with less evaluations than it took Deep Blue to beat Kasparov is certainly very exciting.

Perhaps one of the "stubby hubble" telescopes the NRO donated to NASA would be useful for this task[0]. They are essentially the hubble telescope with a much shorter focal length(hence the nickname), so one of the uses suggested f

Of course, the author seems to be ignoring the fact that 3d printers can't make everything and will not for the foreseeable future. Not to mention, the issue with some of the 3d printing processes themselves being patented.

They are here right now, you can buy them at walmart. But the tech that could change everything is HP's new printer. It prints strong parts fast in color. If HP doesn't fuck it up(they probably will), they could have them in walma

Japan has hardly lost the robot race. Why? Well japanese robotics companies held ~61% of the industrial robot marketshare in 2011[0]. Second, they're a big producer of actuators for robots, so they're in a good position to supply

It's not trivial. Imagine trying to computationally model this. And this does have practical applications too, better understanding of how ants flow in aggregates could have applications in modular robotics and claytronics. https:

It appears you are assuming 100% efficiency for conversion of solar energy. The maximum efficiency possible for solar cells is the carnot efficiency at 86%.

Plants suck at solar conversion. Plants are typically 3-6% efficient at converting solar energy, while commercially available solar cells are 14-19% efficient. We even have solar cells in the lab that are 44.4% efficient.

Well if you really want to drive down the cost, the best thing to do would be to mass produce the actuators for the purpose. The actuators MIT used aren't really intended as actuators, they're some weird part for moving knobs arou
