Solar oven/cooking

For context, I live in the tropics and get a lot of sunlight for most of the year outside of monsoon season.

I was recently chatting with some coworkers and one of the mentioned baking cookies on their dashboard during the summer, and I remember my brother mentioning doing that when he lived in Arizona. That is something I could probably do here, but we always keep a sunshade up in our car so it isn't incredibly hot when we get inside.

This got me thinking about solar ovens since I remember seeing a video of someone using one to cook online awhile ago, and I was curious if anyone here has one or has any experience using one and if it was worth it or if they would have any recommendations.

    Modernist Cuisine presents: Cooler Steak

    If not powerful enough, take some inspiration from the Mont-Louis Solar Furnace (IEEE) and make a miniature home version for instant cooking

    Constructed in 1949 in the citadel of Mont-Louis in the French Pyrenees, this double-mirror solar furnace [PDF] concentrated the sun’s rays to melt just about anything that wandered into its 3,000 °C beam. Engineer Félix Trombe [shown below] designed the solar furnace and used it for high-temperature experiments on materials and to demonstrate how to fire ceramics without using wood.

    In 1975 the solar furnace was removed from the center of the citadel to a spot near the city walls, where it continues to be used for educational purposes. On a sunny day, the furnace can concentrate 50 kilowatts of solar energy into an area of just a few square centimeters. This is enough focused radiation to instantly ignite wood or liquefy a steel plate in a matter of seconds

    In all seriousness, I would try a cookie bake for sure. A cooler and some foil in the sun should do it. My area is more suited for outdoor freeze drying....

      I'm hoping if we moved back to our old place we're renting out or settle down in this area we can get some solar panels as I can only image they would pay for themselves before too long with the amount of sun we get in the area.

    I've seen YouTube videos of people using really big fresnel lenses to focus sunlight similar to a magnifying glass but on a larger scale and they get hot enough as to be quite dangerous and even melt metal. I imagine you could use it to heat a metal box and have a rudimentary oven, or heat a pot to boil water, or possibly even cook something like a steak directly.

      I've seen some of those as well, the sun is no joke! I was leaning more towards a premade one that I could easily store if needed, but I may look at doing something myself. Since I work from home...

      I was leaning more towards a premade one that I could easily store if needed, but I may look at doing something myself.

      Since I work from home having something like this would be handy since I'm thinking I could set it up and let it cook in the later morning/afternoon when we get a lot of sun on the front of where we're staying.
