World's Lightest Sun Powered Drone!

in STEMGeeks2 months ago

Ok, this is something really cool I stumbled upon today.

Let's first start with a video

So what you just witnessed is a rest flight of CoulombFly, the lightest solar-powered drone.

Developed by researchers at china, this little guy fits an average human palm and weights just 4.21 grams and can carry a payload of roughly 1.59 g.

According to the guys who made it, it's about 10 times as small as and roughly 600 times as light as the previous smallest sunlight-powered aircraft, which a quadcopter that’s 2 meters wide and weighs 2.6 kilograms. I pretty much know nothing on the subject so I'll just take their word lol 😆

Here's another test video

CoulombFly uses a new innovative propulsion system that is more efficient than traditional methods that allows it to fly for much longer periods of time.

Here's a quote from Mingjing Qi professor at Beihang and leading scientist of the project

My ultimate goal is to make a super tiny flying vehicle, about the size and weight of a mosquito, with a wingspan under 1 centimeter

Anyways, nifty little thing. Here's a link to the article where I came across this thing if you'd like to read more on it. And here's a link to the actual paper, yawn!

Solar powered drones eh? It is a very nifty invention and very environmentally friendly too! Could be some reliance issues though. It won't be too useful at night time if it needs direct light for real time flying. And it won't help the US Army drop those bombs if it's a night operation!

Well that's just a concept pretty much and looks really fragile for any serious application!

It sounds like an interesting idea but I wonder if it will be used for more nefarious purposes if they want it so light and small.

As is, doubt it.

That’s almost as small as your …….. 🤣🤣🤣🤣

My what? 🤫

!pimp

I want to see when will be available

!PIZZA

Probably never lol, for now it's only a prototype

It looks like if left it would fly to the sky forever 😂😂😂😂

Lol

PIZZA!

That's cool! You know that they are probably already building spy drones from it!
!LOL

What's the difference between a glutton and a hungry man?
One eats too long, the other longs to eat.
