What happened to Aerovelo Inc, can't find anything new from it online

Why did you put background music? Just because you could? There is already echo in the warehouse, and background music makes perception of your narration much harder. Did it ever occur to you that if people want to listen to music while watching a video, they will just listen to whatever music they like?

Significant lift enhanced from low ceiling above the craft, and induced low pressure area above it -- reverse of ground effect. It's unclear that Atlas would have succeeded in still air, over an open tarmac, with only the sky above it. The low ceiling also restricted and impacted re-circulation patterns for each rotor at the center of the craft. I'm not sure why the AHS Sikorsky Prize team never questioned this, as it appears to be a carefully constructed breach of the original prize intent. This fact was carefully avoided in their ground effect modelling. Many people flying drones inside have already encountered the strong suction effect of getting to close to the ceiling ... which unlike ground effect is pretty stable, getting close to the ceiling rapidly increases lift until it impacts the ceiling uncontrollably. Google this: "quadcopter near ceilings"

Where can I buy one

The ball is spinning; the bike is not.

We just need so so much more of this. Imagine if science/development never turned away from human power in favor of various fuels. Progress would be slower but what kind advancements would have possibly been made? We could be living in a world where everything is just powered by our own movement...

Fabulous, what a great team work and engineering and athletic , all the best .

That's great video editing. You can't even see the wires.

how many watts was he producing?

Lets bring it back :D

That's amazing!!!! I was tearing up!

My only concern is that the rider will be sweating in that bike. I mean why no windows?

That is not an ornithopter! It is a human powered glider.

rubbish, when i was 7yo, i dedicated myself to focussed physical training program and achieved human flight by opening and closing my umbrella at a rapid speed.

Does the rider not want to be named??

Exceptional energy efficient transportation technology developed that the stupid greedy ignorant automakers need to adapt into mass manufactured vehicles, velomobile, scooter, bike, motorcycle, car, SUV, truck, bus, automobiles or passenger vehicles that are aerodynamic like the Aptera solar electric //

So, where's the Add To Cart button??

Great Scott!!

i think its time to add dimples on it like the golfballs, and shapes like the sailfish to see if this will make it go even faster

You are wasting energy pushing two wheels. Vehicle should only have one wheel with a balancing tail.

Still trying to find a vid that details the steering limits. W/ the 93T main chainring overlapping the wheel it looks like only a few degrees of steering in either direction. So they start straight and better keep it straight because if you veer too much there is no room for recovery. Great piece of work and great results.

That guy is strong.

all these have astonishingly small number of view.... how you managed all funding?

This is very cool. And even if such a bike is unuseable in the traffic and daily life it shows the possible improvements of cycle efficiency by an aerodynamic design. Even twice the air resistance of this bike is far less than with a standard time trial bike and would probably be fully useable for daily use. I think that is what the velomobil has. Just a note: at 3:10 the tire definitely protrudes much more than 4mm, closer to 10-15mm.

The cherry on top is the tron music. i love this👌🏾👌🏾

How this slow helices takes flight?

Congratulations!

Sick. Well done y'all.

The part that seems most like magic is the way they transported the power from the crank all the way out to the rotors using nothing more than string.

Hahaha! That's some serious sh_t!

Looks like a hoax.

How does the rider keep from overheating if he does not have the slipstream to cool him?

Можно доделать эту машину и она поедет ещё быстрей, упор на аэродинамику и более эффективный привод

Говно какое-то

seems like soon to be a future sporting event too!

what did u prove? just earned money via stupid idea....

Awsome

what would be the maximum speed if that was driven by top sprinter

Now give us bike lanes who are worth the name and not just 50cm stripes from the road. Then i get myself a Velobike, its fast (I can output 60-70km/h easily) and makes fun.

Imagine driving and just seeing an egg running on the road like this

not practical off a track where you have a collision or have to stop fast

I am going to buy one in my future. I like efficient vehicles , l am now a child; waiting it to be advanced on that era. Keep it up you are my dream.🤩🤩

The most obvious conclusion upon viewing this video is that birds are truly remarkable creatures. Picture the body of a bird in place of the bicyclist in this video and note the huge surface area taken up by the four rotors. That there is the proof. Even when you consider non-dimensional parameters. For instance, a hummingbird is exceedingly smaller than a human. But aren't there even very large birds that can fly vertically upwards for periods much longer than a minute? And of course this is a helicopter, not a rigid wing aircraft like the one McCready built and which was successfully flown by its human power plant across the English Channel. My advice is, Humans: don't even think about human powered helicopters/drones. You can be much better rewarded by focusing on human powered fixed wing aircraft.

Someone tells Doc that Mr. Fusion is not needed anymore.... Keep up with that legs Aerovelo Team! Congratulations from Brazil!!!!

I want to be your friend

Nice

University of Maryland built one that flew for 97 seconds in 2013.

I want it soon , you have created a dream in my mind about the limits of efficiency, we are with you , keep achieving .
