- Good morning pop pickers, the velomobile skeptic and I headed off to see Mike Burrows at Burrows Corp HQ to check out some of the new updates Mr Burrows had incorporated within the Soup Dragon.
R.I.P. Mike Burrows. I had been looking forward to seeing how he progressed with his streamliner.
Listening to Mike speak is simply incredible.
Nice to see Doc Brown keeping busy. 👍
The world needs more engineers like Mike Burrows, these visits are extremely fascinating.
Mike deserves the Nobel price for biking science!
What an endearing and so utterly British mad professor
I could listen to Mike talk bikes for hours.
"Look Ma, no hands!" Mike Burroughs in his new tackle-steered contraption.
Life goals.
Love Mike great teacher owe the man a lot and wish him all the best with the challenges of his illness all my love
Wow what an epsiode, valuable information and a lot of fun :)
Someone with financial power, hire the guy and let's make velomobiles in UK.
Lovely machine. Great engineering. Must be a very interesting experience to drive. I have tried to imagine how I would design a fast velomobile, and this is very close to it.
Oooh! That was such a great video. I love the Soup Dragon. Mike is great at naming things as well as designing them. The Soup Dragon was a character from the Clangers a TV programme from my childhood and I’m sure from Mike’s as well. It is always great to see Stuart as well.
One of the peculiarities of a streamliner is that without some sense of peripheral vision it becomes very difficult to tell whether you're leaning to the right or the left as you pedal. It takes time to fine tune your sense of balance and to trust it above even your view straight ahead.
Yeah, a bit like politcs...er...Brexit!
Love your videos especially these ones with Mike, he is so interesting and knowledgeable.
Regarding the wheel spinning faster when enclosed around 10:30, it seems to me that when inside the box the air around the wheel will spin up in delayed sync, reducing air friction along with a very minimal flywheel effect. With little air exchanged, there isn't a constant energy loss from incoming straight airflow getting twisted by the wheel, even a disc wheel.
Marvelous. Good old British common sense empirical engineering. Just love Mikes enthusiasm. Giving away hard earned 'trade secrets', not so sensible in a competitive world?
Havent watches you in a while.good to be watching again👍🏼
That landing gear is so cool!
I met you earlier today at the café in the park - I look forward to seeing what you get up to. Good luck
Thanks Stephen.
@velo-ads I would extend the plexiglass windshield to improve visibility.
Esse coroa é um gênio sou muito fã dele,ele tem a inteligência do Batman.
Á como gostaria de morar aí na Inglaterra,,para poder aprender com ele,,tenho ideias nas não tenho um professor desse, aqui no Brasil.
loved the content. :15 and 12:31 that's what she said.
I'm curious about what Mike's take on a more practical recumbent would be. Something that can be used for touring, and every day use? At least I've never seen one of his recumbents with a compartment as large as a full set of panniers and touring bags, but maybe there is one?
Fabulous!
Inside-the-tent insights into another bicycle designer archtype, the-designer-chasing-a-number rather than designer-with-design-to-save-the-planet. I wonder if among velomobile skeptics, might "shouldery" be a common attribute.
Fantastic
Man looks like a mad scientist presenting you his time machine :D If you know who i mean.
Surprised by the 75deg head angle. Previously I have heard Mike say zero is best.
Wonderful, thanks! 😊
It's like a peanut 🥜 shell 😊
Open a vent in the tail & suck the boundary layer into the hatch slot.... :)
In javelin (track and field) the spear had ribs or knots in the front before it got prohibited.
That's farking joyful insanity! I'll stick to my Rans thank you!
This guy reminds me of Michael Gambon.
No Battle Mountain this year guys. :(
Tá mais do que na hora de usar outra forças livre para correr mais um pouco nas bikes
Hello dear friend can you goes up hills with it eir 😊
Hello dear so Sir how does it turn 😊
Back in 1991 I was a spectator at the European HPV championships at Wolverhampton, and one of the events was a straight sprint on a closed road, I'm sure one of Mike's creations was there and set the top speed, ie The Bean. Is my memory correct?
If I remember correctly, the Bean was designed by Miles Kingsbury of Kingcycle.
Cant ride this at battle mountain. Its got no roll cage or safety harness.
You could turn it in to a trike
Yer looks fast parked up
Acceleration matters for the hour record. You can't lollygag for the first 5 minutes slowly getting up to speed or you can plan on achieving a "not-as-fast-as-hoped" average speed. At the World Human Powered Speed Challenge at Battle Mountain, NV, USA, acceleration matters for the top speed attempts. The record is already "distance-limited" by the 5 mile runup. Riders in the fast vehicles are putting out plenty of power from time zero and could go faster if the course were longer. To get into the group that's allowed to use the 5-mile course, one must first qualify on the half-length course with a specified minimum speed. Acceleration matters for those attempts as well. The faster you go, the higher your seeding for selecting long course heats.

Russell managed the single gear and successfully got the vehicle up to speed.

I'm late to this party, & indeed wasn't invited, but I think he's possibly going the wrong way with "as smooth as you can get". It used to be in that engine tuning, performance tuners would polish the surfaces of the ports believing that to improve flow but, latterly, what's been found is it's better to roughened them up a bit. Didn't golf balls go through a similar evolution from smooth to dimpled? He should try a sand-like finish, or mix glass beads into the topcoat. Ditto, did they look into Kammbacks?
In autos, Kammbacks provided the biggest drag coefficient reduction. Similar benefits were found in sailing with Schilling (or fish ail) rudders.
The other technology that is successfully used in engine port tuning, which is all about fluid or gas flow, are anti-reversion approaches. Basically, flow wants to move in circles, it wants to move back on itself, so sometimes & in some places, you need barriers to stop it from doing so.
The wheel is like a valve or valve guide sticking out into a port, so what they would do there is use a small nipple or fin ahead of the disruption to split the flow around it.
The problem with "going by the book" and using the computers is that, ultimately, it only takes you as far as everyone else.
The issue here is bicycles don't move fast enough for boundary layer techniques to work effectively, so the same techniques don't necessarily apply.
@@BrunodeSouzaLino I don't know. It's remarkable how poor Google is in providing simple answers to simple questions like what speed for it to take place.
