Lots of sky traffic...

don't even have to cook it!

Silliness. People talk about this like they could really do it. So many things are wrong with this idea, you should just see it as the joke it was meant to be.

drone delivery. It's very efficient and cost effective and with GPS and computers they could easily find houses and then have someone guide it to the door. I am sure Domino's is doing it as a publicity stunt for now but this type of thing is just a few years away depending on how the legal issues are worked out. However according to the article Domino's is testing it for real in the UK, not just a publicity stunt. Here is another article on drones and future delivery: http://www.eagletribune.com/business/x326077930/Businesses-look-to-use-drones-for-commercial-purposes

And here is a company that has been delivering taco's since 2011 but is now being blocked by the Gov. http://www.huffingtonpost.com/2012/03/23/tacocopter-startup-delivers-tacos-by-unmanned-drone-helicopter_n_1375842.html

Problems:

1) Wind
2) Range of remote control device
3) Wind
4) Whirling blades near a customer's face
5) Wind
6) Making change

And did I mention wind? Helicopters don't hover relative to the ground. They hover relative to the air they are in. If that air moves, the helicopter moves. That means if the slightest breeze comes along, the drone helicopter lunges into the customer's face, or into power lines, or into a window.

It is neither efficient, cost effective, nor safe.

BTW: Tacocopter is a hoax. http://eater.com/archives/2012/03/27/tragedies-the-tacocopter-was-just-a-hoax.php

Of course the technology has a ways to go for regular companies but it's not that far away. If companies knew it was going to be legal then there would be vast amounts of money investing in the technology to work out the bugs. Right now we have Google cars that drive around with no driver and have gone hundreds of thousands of miles without an accident. They can stop at lights, change lanes, anticipate what other vehicles are going to do etc. If this can be done on roads it can more easily be implemented in something in the air that would only need to dodge things near the ground. Dealing with wind and range of control have already been worked out. Watch a couple of videos on the work Switzerland is doing with drones. They can easily handle wind. You can literally knock the crap out of one and it re-gains it's control in a fraction of a second.

The technology is not the problem drone delivery would run into, the obstacle is the laws that would prevent them from ever taking flight which would probably bee wise laws.

There are some nice videos on you-tube about drones like this one:

How many kids do you think will try and knock it out of the sky for free pizza?

I'm keeping an eye out for one myself.
