TL;DR Summary: We were tasked to create a water powered car for a project for engineering design and the main specifications is as follows, it must hold 0.7L a min of water. For the first run it must move as far as possible with 0.5L of water and then on the second run it must be able to move between 3 to 5 m with an unlimited amount of water

So far we created two designs. The first design was a three CD wheel car. The back wheels had a water wheel and a sort of funnel to pressurize the water onto the wheel to make the back wheels turn to turn the front wheel but the water wheel was not moving when water was released onto it. It also did not have sufficient storage as water was released to push the car
The second design i lifted the waterwheel, and created a separate axle for the back wheel, adding another front wheel so there are 4 wheels in total. I created a sort of a pulley conveyor belt system where if the waterwheel turns, the first pulley turns with it and therefore the second pulley turns the back wheels making the car move.
But the waterwheel on turns without the belt and with the belt the back wheels do not move.

Please help. We have this project due on wed and we have no solutions working as yet.

Welcome to PF.

Can you apply air or elastic pressure to the water, say in a balloon, or is gravity only permitted.

For maximum potential energy, raise the water reservoir, while keeping the water wheel low. Release the exhaust water backwards, (as a positive thrust).

Drive only one wheel or axle.
Avoid flat or 'v' belt drive, use a chain, stepped belt.

Provide a link to the rules of the game.

If another energy source is used, I must be able to prove that the produced energy is greater than the initial energy, I've enclosed the rules if you would please kindly assist.

Since it was due on Wednesday (2 days ago), can you say how you did? What did the winning car look like?

It moved 2.5m on the first run and 3m on the second, it was quite a marvel, my teammate had incorporated some of the previous designs we did and created this.

Related to Advice needed for producing a water powered car model project

1. How does a water-powered car work?

A water-powered car typically refers to a vehicle that uses water as a source of hydrogen fuel. The process involves electrolysis, where water (H2O) is split into hydrogen and oxygen gases using an electric current. The hydrogen gas is then used in a fuel cell or internal combustion engine to produce energy, which powers the car. It's important to note that the car itself is not directly powered by water, but by the hydrogen extracted from it.

2. What materials and components are needed for a water-powered car model?

To build a water-powered car model, you will need the following materials and components: a small water tank, an electrolysis unit (electrolyzer), hydrogen storage tank, fuel cell or modified internal combustion engine, electric motor or engine, battery pack, control circuitry, and a chassis for the car. Additionally, you may need tubing, valves, and safety features to handle hydrogen gas safely.

3. Is it safe to produce hydrogen gas for a water-powered car model?

Producing hydrogen gas involves certain risks, as hydrogen is highly flammable and can be explosive when mixed with air. However, with proper safety measures, such as using leak-proof containers, proper ventilation, and avoiding open flames or sparks, it can be done safely. It's crucial to understand and follow safety guidelines and protocols when working with hydrogen gas.

4. How efficient is a water-powered car compared to traditional gasoline cars?

Water-powered cars, or hydrogen fuel cell vehicles, can be more efficient than traditional gasoline cars. Fuel cells convert hydrogen into electricity with an efficiency of around 60%, while internal combustion engines typically have an efficiency of about 25-30%. However, the overall efficiency also depends on the energy required for electrolysis and hydrogen storage. Currently, the technology is still developing, and there are challenges related to infrastructure, cost, and energy efficiency.

5. What are the environmental benefits of a water-powered car?

Water-powered cars, particularly those using hydrogen fuel cells, produce zero emissions at the point of use, emitting only water vapor as a byproduct. This can significantly reduce air pollution and greenhouse gas emissions compared to gasoline or diesel vehicles. However, the environmental impact also depends on how the hydrogen is produced. If the hydrogen is generated using renewable energy sources, the overall environmental benefits are much greater.
