Scientists in Finland have built a revolutionary battery that runs on sand! 🌍⚡
This 10-meter-long, 15-meter-wide battery uses 2 million kg of sand to store heat at 600°C, generated from excess wind and solar power. When needed, the stored heat is converted back into electricity.

This eco-friendly solution is cheap, scalable, and sustainable — and could change the future of energy forever.

Watch till the end to see how sand could power entire cities! 💡🔥
