# Developing a solar powered traditional river boat [closed]

I am currently in Indonesia with fellow students working on a project to experiment and build an alternative energy source to propel boat with optimal efficiency and also to minimize the use of diesel and petrol to combat pollution and limit the use of natural resources.

My team intend to develop a solar powered battery for a single deck river boat commonly used as inter-island and river transport.

I hope you all are able to provide some insight and advise on how I can proceed with this project. The only problem I had is the math to calculate how much watts is needed to optimize the boat movement. In theory is it possible for a simple solar panel set up to power the motor system of the propellor.

THANKS!!

• I'd start by trying to measure the drag coefficient of the boat in a flowing river. Measure the speed of the water. Hold the boat by rope in various flow rates and measure the tension in the rope (newtons, N). That will tell you how much power would be required to drive the boat at that speed through still water. You'll need additional power to actually accelerate the mass of the boat and more again if you wish to be able to motor upstream against the current. Nov 11, 2023 at 17:02
