How to cook eggs in the car while looking for a beach

Published on May 29, 2026 | Translated from Spanish

Summer brings extreme temperatures and long lines for parking. An inventor has taken advantage of this situation to create a homemade solar oven that, placed on the dashboard, cooks hard-boiled eggs while you drive around looking for a spot. The idea transforms the car's waste heat into a practical solution so you don't arrive at the beach hungry.

The device uses a cardboard box lined with aluminum foil and a transparent glass that creates a greenhouse effect. It is placed on the dashboard facing the sun. Internal temperatures reach 70-80 degrees Celsius in 20 minutes. The eggs are introduced raw into a black metal container. The key lies in the orientation and sealing the system well to retain heat. It requires no electricity or fuel.

Now you can show off sustainable cooking while the neighbor in the SUV passes you on the right. The problem is that the egg smells like a reheated car and seat cover. If you also have the window rolled up, the aroma will follow you to the shower. But hey, it's ecological, cheap, and saves you the line at the beach bar. Just remember not to confuse the egg with the pine air freshener.
