World's smallest engine?

http://geeknizer.com/worlds-smallest-petrol-engine/

Not sure I really believe this, but maybe it's time to invest in some of that itty bitty DSM2 gear and start winding actuators!

well, being able to make one is one thing, being able to PRODUCE them and have them all be cost effective with batteries is the real challenge

though having a hybrid aircraft would be sweet, no charging, just refuel and back to flying!
thats why i want them to get fuel cells down in size and up to lithium power levels.

I want to see a video of that little guy in action! If those figures are correct, I'd buy stock in that effort immediately.

I don't tink they are hand made. Probably laser machined or something similar that can be automated. Maybe shapeways can dupe them out of stainless!

While I'm dreaming about it maybe I should also ask about nano turbine engines for some living room jets!

Exactly. Read it again. Or are you agreeing with me?

Would need an FPV system so I could hunt down a mosquito or two if they wake me up at night.

Good call. Nobody, including me has noticed that. I'm going to check out the watch counter in Macy's and ask if they have any petrol powered watches.

Easy come, easy go.

Maybe when nanotech takes off.

Usually when my flying buddy and I start playing with RC gear his cats leave. The really weird exception was a small quad heli. Their eyes bugged out but they looked ready to pounce. I think it may have sounded like an insect to them. It was really interesting to watch. Land and they'd stalk over to it. Add a hint of power and they'd back up about a foot. Hover and they'd hold their ground staring at it.

Great cats even if they did chew up a couple of foamies when they were kittens.

i noticed a few neighborhood cats liked to stare at my quad and if i landed near them, they'd croutch as if to pounce, but never would

also, i do recall a popular science issue that had these in it many years ago. they were also looking at nano turbine engines made from silicon.

If motors like these ever become a commercial reality at low prices it would really be interesting to have tiny quads to fly. I've flown my AR Drone in my apartment (no videos, the place is a total mess) but it really needed more room although hovering in front of myself for an airborne portrait was possible it was not comfortable.

My UM helis are also a bit intimidating when up close. I fly them anyway, but mostly just over the bed. I practiced daily on Aerofly or whatever the Ikarus one is called, but when the heli is real, however small it seems a lot more difficult.

Smaller is better since the same flying space provides more room for error.
