The plane "kit" is a PDF so it was easy enough to re-color.  My 3 year old picked the colors!  I also sized it up from 1:33 to 1:24.

Paper is a wonderful modeling medium.

And 3 year olds can be so much fun - sometimes.
Bet it was a great afternoon, you'll be surprised how much she will remember the time well spent !

Hi LarryC,  My advice, don't waste your time, you are being played like a "puppet on a string".

Hey guys, it is time again for throwing some apples to see who can have a bite on the fly
Larry, throwing apples is more their cup of tea (3 yr old's according to wildew) .  I would guess that a XLS for a ballistic apple trajectory would get you a better response.

LarryC .. I'm on holiday for a few days so just visiting.

I suggest your request is better directed to Dennis [see3d] as he has a sim that is effectively a single Pod & 1 Riser analogue, when slightly modified almost identical to your spreadsheet picture - he is able to lock the Pod chamber piston in place to replicate your spreadsheet snap shot of static start conditions [including dimensions & water levels] just as you've used - then he can give you the dynamic analysis as the Pod & Riser is released [re Seamus's comments] - this will show capacity to do Work rather than static force analysis.

IINM he will need to know what the estimated mass of each component is so that he can work out the neutrally buoyant situation [the amount of precharge required in head] - my apologies if you have already stated this somewhere recently.

Dennis has been saying this for about 150 pages - he has an excellent resource & has put significant time & thought into building the sim so that it accurately predicts behaviour - what better way than to compare it to your spreadsheet of start conditions & give him some valuable feedback so he can make further progress & at the same time encourage him for his not insignificant efforts creating a dynamic model ?

Hi,
    Wayne and Red_Sunset just ramble on these past few days, I think they might do better as politicians.
Tinsel has told me that even if the thing did work I would need a unit considerably bigger than my house!
To give you lot a bit of an idea what's needed is to look at the amount of water you have to shift through
turbine to give 10kw. You would need a head of say 30 metres and a flow rate of about 50 litres a second.
What's 50x60x60x24? That's a lot of water for just one day!
