This free and open source turbine can be built for half the cost of a 120 watt solar panel, and will produce about ten times the power (5kWh with 3m drop and 35 l/s flow) per day. It can be plugged into any appropriate waterway without the need for earthworks, and uses only basic off the shelf and recycled materials, and simple hand tools.
Details on materials, tools, and step by step build instructions are available (free) at:

Mister Brown and Squeaks decide to design a solar oven, so they can cook their lunch while they play outside!

Second Grade Next Generation Science Standards
Disciplinary Core Ideas:
ETS1.A : Defining and Delimiting Engineering Problems – A situation that people want to change or create can be approached as a problem to be solved through engineering (K-2-ETS1-1).
Performance Expectations:
K-2-ETS1-1 Ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
K-2-ETS1-2 Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
Abundant sunshine, wind and various critical resources give Australia a distinct advantage when it comes to the green energy transition. So can it lead the charge and become a clean energy superpower?! Australian correspondent Rosie, who you may recognise from her own channel (https://www.youtube.com/c/engineeringwithrosie) , looks at how the country could be charting its path to 100% renewables from wind, solar, storage and interconnectors as well as creating a hotbed of minerals and resources needed for electric vehicles. Enjoy!
