Beer-delivery drone grounded by FAA

That looks like a MK hex. That should bring six beers fairly easily.

There are some incredible proprietary and open-source drone tools out there now. The toughest problem is still obstacle detection, particularly around landing. Six (or eight) 15" razor-sharp carbon fiber blades spinning at 8,000 RPM can really mess some shit up.
 
These drones will become something the FAA/Gov't has to formally address in the near future. Particularly with Amazon's drone delivery service as well.

Article reads legislation won't be ready til 2015 and comercial drones won't be flying til 2017

What's bringing this issue to the forefront is the promise of Lithium Sulfur batteries. Right now, electric motors and lithium polymer batteries limit us to 15-25 minute flight times.

It's really frustrating, because as you add battery capacity it increases take-off weight -- but usually you come - out ahead. But then your amperage requirements per motor requirements go up, so you go to a higher rated motor. But that drives your weight up (it's a vicious cycle).

Lithium Sulfur is four times the energy density of lithium polymer. That means hour+ flight times, which makes a lot of new applications possible.

Sounds like the space travel problem with fuel weight
