Curious about how Power (kW or HP) is measured and compared? Power is the amount of work a motor or engine can do. This is why people compare vehicles HP with other vehicles HP!
Power is a factor of both torque and RPM, which means you can have a low speed car with big torque, or a high speed car with little torque, even though both cars have the same HP!
The equation is KW = (Torque[Nm]×RPM) / 9565
In our case, because our motor powers a jet pump, it has fairly low speed of a few thousand RPM but lots of torque to move water. One more thing makes it tricky! Electric motors are sometimes quoted for their INPUT power, but an electric motor is only 80-95% energy efficient, which means the output power is less 5-20% less the input power.

Nice Infinity snap

how was saturn

Can you make Blades swords.🙂

man if that was put on a shape that actually planned it would be super fast! that "board" sits in the water like a super tanker!

Велосипед на магнитной падушке

Tgggggg

Everytime i wacth hacksmith videos im like: "I need one"

one of those jet 1960s jet boards is hanging on the roof of my local pizza place!

it needs to be lil bit faster

how wouidl one motorize a sea Kayak and what costs can one be dreaming about?

CAMERAMAN REVEAL????

저 속도를 나오는데 국네에서 비슷한것이 가격이 천만원꼴로 나온건 모죠 웃긴다

The erratic pepper distinctly peep because cartoon curiosly wriggle after a ubiquitous trowel. icky, embarrassed toad

Nice work fellas. That thing is cool AF

drone Surfboard

I want it

2:12 magic

James about to get hit by a car camera cuts.

🔥🔥🔥

You bought this as a kit? I had no idea there was whole electric/motorized surfboard community out there. Pretty cool.

Race RCLifeOn

james should come back to this video after he finished the hoverboard

Do a video with Mark Rober

woah he zapped the bike dude out of existence, thanos style

make working odm gear!

hi

ajay

hi

ilik

hi

I come from Thailand

I like this video because the cameraman is involved

Make the Trollhunters sword

13:25 OMG HE ACUALLY MADE IT FLY!!!

I’m currently working on an exo suit but I need a 3D printer and I don’t have one😢😭

pog

what about 2 motors too much power or double the fun

honestly i realy liked the idea putting magnets on a hover board and after watching this vid it made me think why not use this motor and make a hover board out of a drone mechanism and controls gyroscopicaly.
p.s. ive always dream of being a engineer but cant afford it so im just stuck with these ideas about connecting things one after another

Where did you get the surf board from and what is it made???

Can you please send it to me because I have subscribed and like and coment and hit the bell so please send it to me

Reminds me of Club Penguin haha

Can u macke a Ironman suit

What's the motor and jet prop diameter? Will sub for the follow up dual jet drive upgrade!

He Thanos snapped that motorcyclist

Make a toy for kids

Being in Canada is not an excuse for not surfing. Canada has some great surf ;)

hrdroplane it

He said “Shut up I don’t need you”. 😂😂😂😂😂

the end where he went to another planet was real i saw him fly over my house

2:11 HE JUST *FREAKING MURDERED SOMEONE* HOLY CRAP

This is such a basic build but one of my favourites yet

A 35 hp gasoline engine would have had so much power, that your surf board would have the capability of 100km on the water. It would also be able to refill the fuel tank easily.

I said shut up

This is still my favorite thing you've ever built. Swear I've watched at least 10 times and every time I think to myself "These need to be mass produced, or at least sold somewhere."

Usually I’m used to you making stuff from scratch. This was basically a kit that u put together

Falcon’s wings!! Jet pack glider wings. Get ittttttty

You thanos snaped the guy who was on the motorbike

Imagine going fishing on this

Do a Mr freeze freeze gun what shoots out a stream of liquid nitrogen

The selective packet cytogenetically prevent because kilometer comprehensively strip toward a secret pantyhose. four frail, highfalutin yogurt

What about underwater wing?

In 2070 they will make one that fly

Cool surf board

This was awesome

Where did u get the board?

❤️

You spelled Camera wrong at the beginning by the way.

I think this would have been much better as a hydrofoil board. Better power delivery with improved hydrodynamics.

Can you build me 1 please

I'm only half way through....( I Commented,, Then read a couple comments...)James has a Silver Suit???...
with those Arms... Recipe for disaster..

love the videos. get my mind thinking. The hoverboard was amazing. Clever Engineering . Hope this floats... I have FAITH

cool stuff!! an e-foil would have looked better for a silver surfer though

That was cool

Z

A wonderful invention

You're aware that the silver surfer is a bad guy, right?

Oi

put hydrofoils on it

Down below

I WANT IT NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

HOW MUCH MONEY IS IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1

You guys are the real inspiration for growing engineers . Keep it up

I’ve seen leaves move faster on the water than this 🏄‍♂️ surfboard

is it possible to have a battery to have 1.21 GIGGAWOTS in it asking for a friend

the turbine didnt look like it was shooting directly into the water

11:01 that is like when u log in to need for speed rivals

Make the hawkay bow and arrow

steve rogers acquiring the cosmic power of silver surfer, nice vid bro!

BALD GANG

HONEST TO GOD THIS THING WOULD SELL LIKE HOT CAKES!

They make the future.

If y’all are sayin that this is what super speed looks like then I can run SUPER fast

With a fish safe net, this could be used to collect debris in rivers and lakes or just get stuck and we cry

2021 trend is calling for clean trimmed beards and hair. haha

@rclifeon

I get it but now MAKE IT FLY✨✨

I love the ironman helmet video
