I am surprised they didn't ask you to bring a jet and do a demo.

When does the show air?

Yes the boys did ask. But that just too much and need submit permission.
I told them Woodland should had open house soon at new location. I'll let them know the date to come out.
I show them bunch of my videos. Funny their even ask whom video it. It good steady hand for following fast moving aircraft. I told them you are looking at him.
Ben the camera man said. When ever you need part time job. Come and help me.

Hi,

So did they English dub you, or did they use subtitles?

California most speak Tamlish. So no problem at all.

True that.

It will move in the direction the jet is pushing but slowly. Newton's law is in effect but the turbine thrust is partially cancelled out by the air hitting the sail, again Newton's law. If 100% of the energy of the air hitting the sail was converted into thrust the thing would stand still. However there will be losses so it will move in the durection the jet is pushing but more slowly.

Sean watch MythBuster very often. He love come back for second visit.
Tori and Grant give him tour around the shop showing him a lot stuffs.
The producer just love to have him around. Most kids drive them nut. But Sean just know what to do. As soon he hear 3-2-1. He kept quiet.

but I think the sail is too far away from the nozzle to be a thrust reverser.

... yeah, but it is big....

Tam! Thanks for sharing this story! Can't imagine him riding a jet powered skate board! IMHO....I think that the skate board will stand still, due to Newton's Law: For every action, there is an equal and oposite reaction. Or it does burn the sail.....lol.

It's a JetCat they're using, not a JetJoe... so it will move one way or the other.

It's easy for those who know physics! Inital move then stability! Ha problem solved! F1=F2

David gets my vote !!! I agree. I do understand Newtons law of action and equal and opposite reaction, but the two actions are not equal.... there is a loss of thrust in the air between the exhaust nozzle and the sail. Therfore the Turbine will prevail and the skateboard will move in the direction that the turbine is wanting to move it. not the sail.

That's all I got to say about that !!

The vote it really good.
Almost everyone vote got it right.
There physic law, mechaical law and luck.
This is a good one to watch for the result. When it air. I'll explain what it did.

Yeah if I do work with writing or teaching.
But my works with hand skill.
So the hand doing the talking.

Correct,

The biggest energy loss will be the heating of the sail.

Tam, what is the sail made of?

*edit*... Just to be clear, the reference to 'Forward' is the direction the turbine wants to go in a normal set-up.. yes? [8D]

Like others have stated, I think it will obey Newtons third law and travel in the opposite direction of the airmass flow.

Which direction it that is, will depend on how effective the “sail” is at directing the air mass. If the majority of the airmass flows back towards the turbine, the skate board will travel sail first. If the majority flows around the sail, it will travel turbine first. If there is an even split it will stay still.

I suspect it will travel sail first.

I would like to see the same experiment using a proper aerofoil section shape sail, with the air directed to flow over the sail.
