Pot pot powaaa

[Vulkyn]

Well yah .... just bare with me ... pot pot boats !! Hit a snag in my boat building so im diverting my energy into small toy boats ...

I was thinking, if i redesign it so the intake is at the front (with a check valve for inflow) and output from the rear (same but check valve for outflow), build it out of plywood and epoxy (fit a receiver and servos for remote control navigation.) how much power can i get from the small boiler ?
Just need to figure out the weight and the engine size for my ultimate RC boat ....

[Vulkyn]

I think u got the wrong thread ... this is candle power not solar power ....

[wardd]

but solar is to wind what candle is to diesel

[Vulkyn]

*sigh* ......
Ill start building it tomorrow ......

Vulkyn, success with the Pop Pop boat..!!

Let me quote here a part of my post from elswhere on the forum.

At least it's on topic here and Pop Pop interested visitors will have some links at hand......

Inlet is on one side, propulsion is on the other side, so it will go round in circles.

PS - that's called into question, read the thread to learn more . . . . . .



------------------------------------------------------------------

After you get tired of that you can build a double engine with the engines mirrored so the boat will go strait.



------------------------------------------------------------------

This one needs a double engine too..!!



PS - This boat is OK . .
Didn't pay attention to the twin keels with integrated rudders (fixed?) and overlooked the high-efficiency exhaust nozzles, improved burner & condensor, etc. etc.

You might as well build series and go commercial....................

Link: ‘‘Price is $ 360 plus shipping and insurance (approx $15 ground, $25 air, in US) ~ SOLD OUT ~ ’’

A gap in the market..!!

Good Selling . . .

Cheers!
Angel


PS - there are also cheaper models from outside the US here and here.

Didn't know about pop pop boats when I was a kid; the internet hadn't been invented yet.

So I had to settle for baking powder submarines; my mother sent off a quarter and a cereal boxtop for one.

Let's see; they started selling them in 1954. Since I was born in 1949 and got my first one when I was 5 years old, it looks like I had one of the originals....

add: Angel, I don't think a pop pop boat has one inlet and one outlet. If I understand them correctly, each side acts as an inlet and as an outlet. The alternating action is why they pop pop....
