Powering the World with Solar

AreaRequired1000Solar panels take space, but just how much land area would need to be covered with solar panels to provide 100% of this planet’s power needs (including transportation)?  The answer is pretty surprising, as the image here shows (click on it for a larger version).  It helps show just how much energy the sun is sending our way, and what a small percentage of that is actually required to power our civilization.

There’s still a matter of energy storage with solar panels, but I wonder, if long range transmission efficiency could be boosted to the point where we have a global power grid?  The sun is always shining on about half the planet…if that power could be transmitted to the dark side of the planet, there would be no need to store electricity.  Nikola Tesla suggested that just such a system could be possible.  The drawbacks are obvious though…it would be difficult or even impossible to employ Tesla’s system in a way that would allow companies to control who uses that energy.  The business model falls apart, sadly, and we live in a world controlled by business and profit.

MetaPro AR glasses

metapro_1-580x322Shipping next June, the MetaPro glasses offer a significantly more immersive experience than Google Glass, but at a much higher cost…$3,000.   You’ll wear a small computer to wirelessly communicate with the glasses, which can display full 720p HD in a 40 degree field of view.  Potential applications for this all come down to software, which is a bit of a chicken and egg scenario.  Nevertheless, with more products like this emerging onto the markets, I expect the software side of things to pick up pace in 2014.  Meta claims their app store has 500+ apps, which is a great start even if you’re pessimistic and expect most of those to be junk.

The one drawback?  It has built in cameras.  I think people are still going to be uncomfortable around others who are wearing glasses that may or may not be recording everything you say.

HER: a movie about falling in love with an AI

11172839_detThere’s an interesting new movie hitting theaters tomorrow, called Her.  It sounds much like your typical romance movie, except in this case the guy falls in love with an adaptive AI.  Sounds pretty boring, but where it gets interesting is as the AI evolves.  Or at least, so it sounds from the very long review written up over at The Verge (go check it out if you’re interested, but be warned, it gives away a little more than the video preview below does..no big spoilers, but a lot of detail).  No, it doesn’t get all Terminator-esque, it seems to remain a heart warming story throughout, but with some really interesting perspectives on AI and our future interactions with it.

Eliminating automobile windshield wipers

P1_shanghai_street_v006_pearl_white_v4McLaren is talking about applying some military grade fighter jet technology to their road cars to eliminate the need for windshield wipers.  The system would use a high frequency (~30kHz ultrasonic) transducer to repel water, insects, even snow and ice.  It’s hard to say how serious they are…but when you look at the technology in their latest road cars the 12C and the P1, this isn’t quite as far-fetched as it might sound.  The biggest challenge might be making this technology street-legal…windshield wipers are currently a requirement, and car companies have a hard time bringing new technologies to the road (adaptive headlights, for example).  (via The Sunday Times)

3D magnetic storage may be possible

For a long time, conventional magnetic hard drives had a theoretical limit to storage capacity driven by them storing data on the surface of flat platters.  Physical limits on the size of each bit area, and how many platters could fit inside a single hard drive, resulted in huge but still limited capacity.  That 2D platter constraint is on the verge of being broken though, with scientists finding a way to also take advantage of the depth or thickness of the platter, turning each platter into a 3d array of data rather than merely 2D.  With this technology, we may see drives with a capacity of more than one hundred terabytes!  Ponder that for a minute…it’s a truly mind-blowing amount of data for how we use computers today, but perhaps in the future will be laughed at as woefully inadequate like the 64GB drives of today…
