Oh hi there! Have you ever heard of a woman named Mária Telkes? She was a very smart scientist who lived a long time ago and she loved to use the sun's energy to do great things. Do you know what energy is?
Energy is what powers our homes, cars, and everything around us. But did you know that the sun is actually a really big ball of energy that we can use too? Mária Telkes discovered a way to use the sun's energy to help people live better lives.
One of the things Mária Telkes made was a really cool device called a solar oven. It's like a regular oven that you use to bake cookies or cake, but it doesn't need electricity to work. Instead, it uses the sun's energy to cook food. Isn't that amazing?
Mária Telkes also made something called a thermoelectric generator. It's a little different than the solar oven. This device uses the sun's energy to create electricity which can power things like radios or even turn on the lights.
Mária Telkes was a very brilliant woman who loved nature and wanted to find ways to use the sun's energy in a good way. She was like a superhero that used science to help people. We can learn a lot from her and her work.
