Oh Loet!

If You just had had that invention last time in Limfjords competition,
I'm sure You would have been the Winner. 
(He also told me that I should have won the Nobel Prize but I lost the mail)
Should I just increase the volume of container and exhaust dia for
Stunt use?

What about using the solar forces (like in a light mill) to use also the
sunny days! Even if these are few, but they are...

When reading Loet's ideas about water power I remembered an article in our locale newspaper a couple of years ago. The ideas had some similarities and I hereby let you compare it.

To understand the theories you must first know some Swedish geography. The biggest lake in Sweden is Vänern and at it's bottom you find my home town, Vänersborg. At the top of Vänern you find the town of Karlstad. Se "View from above".

The guy writing this article got his idea on a bright and clear day (not on a toilet visit!) at the seaside in Vänersborg. I think he had the famous expression "On a clear day you can see forever" in mind………

As he was standing there at the seaside he was surprised that he couldn't se Karlstad. Instead he just saw water at the horizon. Then he remembered that the earth is a bit round and made up a quick sketch (See "Side view"). When looking at the sketch the idea came striking on him: The water at the middle of the lake is at a higher level than in Vänersborg.

Why not dig a tunnel from the bottom at the middle of the lake down to Vänersborg and let the water flow through a turbine at a power plant?! You could get a lot of energy out of this!

The following weeks he made more detailed plans and diagrams and then he started to try to raise money for the project. But, as he said in the article, "people just laughed at me". He tried to convince scientists at the university, the Swedish inventors society, the Swedish scientific board and others but no one bothered to take him seriously.

I have no idea of the status of this project today as there have been no more articles. But I am quite sure that they haven't started any digging in the middle of Vänern even though we last winter had an all-time record concerning the water level of Vänern. Some streets by the seaside was closed for weeks because you couldn't see them. The level was about 2 meters higher than normal.

Maybe Loet and this man should and discuss how to get energy out of water?

Simply put a can full of beer on each model. Connect models to a tread mill & take it to an English soccer match. The centrifugal force generated by the thirsty fans.

Hi Loet, what's happen in case not rain??
UUUHM!
Any way, you need some more power, you can get if you increase the water tank.
In your case i suggest to pit 4 additional tanks and enlarge the machine base.
In this case you can get more stability in case of wind.( in Holland with rain I think you have strong wind or not).

hi

I propose a racer with a stationary central tank with a flexible pipe to the vehicle. This way the weight or size of the tank & rain water does not affect the performance of the race
vehicle.
perhaps all contestants could be fueled by the same tank?

I won't be experimenting personally because rain is scarce in Australia this year.

What a top idea.. This should get you in strong with a Nobel voted by the
greenies.
If you taper the tube a bit you might get a bit more velocity pressure,
similar to a tuning pipe..
Also, maybe you could use a staged turbine to generate the maximume amount
of power by utilising the drop in water pressure during each of the stages..
Just to add a bit of end pressure, install a few ENO cubes in the line
somewhere..
Keep up the good thinking.. Go back to the toilet!

On a slightly different note,what about windpower.You know those really windy days when you can't fly your combat model upwind,but when the motor cuts you can fly downwind like a kite?
I propose when it's too windy you have downwind competitions,save on glowfuel,eco-friendly etc.
When it is a flat calm day you could ship in a load of English f2c flyers, give them 200 crates of beer and have enough wind to fly forever!

Loet,
for the days that don't rain you could carry a case of beer. just shake it up and use it for Jet propelsion

Found your rain powered racer while looking for information on Adriano models. You mention that the rubber seal on the toilet leaked, well, at least you now have running water. Will contests be cancelled because of lack of rain? As President Clinton said, "define rain". Have you decided on a standard for rain water? No doubt Germans will have heavy water, Kenyans will have genetically engineered water complete with high density superbugs, and the Japanese will surely file a protest against the Germans beause everything is lighter on that side of the world, just look at the claimed dry weight of their motorcycles. I suspect that God designed a +/- tolerance for gravity and the USA is on the heavy side, that also explains the obesity in this country. The damn French will try to weasel an advantage with their benzene tainted drinking water by using an afterburner. Has the FAI been approached on adding this event to the next World Championships? I think you have designed a very exciting event although I think we'll have difficulty running it in this country as the FAA severely restricts the use of rain cloud seeding aircraft.
