good point aobut the "no smooth landing," William K. The more blades the merrier.

Rob, the neatest thing that I have seen had 16 blades on a frame with what looked like a lawn chair in the middle. It could take off and flynand never look like it was working hard. Of course the challenge would be the batteries to keep it in the air, but I am thinking that a small gas engine spinning an alternator could be the answer there. Of course controlling those 16 fans to steer and drive did take a controo computer of some sort, but that should not b a serious problem. And it would be safer, since it could lose a motor or two and still land safely.

Some of those military helicopters had a glide ratio like a rock. No smooth landing if anything breaks.

That's a really good point, Barrar. Also, I would think that air space would be an issue. Aren't flying things supposed to be tracked by air traffic control?

You'll want some kind of liability insurance if you're going to be flying one of these things in an inhabited area. If it goes out of control and hits someone, or something, it can do some expensive damage.

That's gotta hurt, Tdekochip. Some of these are toys, some are quite different from a toy.

Some communities already have laws against flying models or toys, and a drone isn't really much different.  I used to fly models, and prop bites can be pretty nasty.

 

That's me in 2002:

I know. The sky could get crowded, Ann. And loud.

This was fun, especially to see what's going on behind many of those flying robots I've written about. OTOH, I don't want to see them flying around in my neighborhood.

I agree Jhankwitz. Given the low cost of entry, I expect we'll start to see crowded skies.

It will be interesting to watch the evolution of drone acceptance.  We'll likely have increased noise, visual distraction, and crash landings in our backyards, not to mention the urge to use them as a moving targets.  I see it as a long term project.

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.

Cigarette companies are fighting back by buying up e-cigarette manufacturers.
