Electric cement is more than structural—it could make your walls your power source.
Engineers in China have created a cement–hydrogel mix that generates electricity from heat, inspired by plant stems. Meanwhile, MIT turned cement into a supercapacitor—strong and able to store energy. And researchers in Sweden built a rechargeable concrete battery, letting walls and foundations act as powerbanks.
Imagine homes that generate, store, and use electricity all within their structure—no external batteries, no bulky storage. It’s the kind of breakthrough that could redefine green building and smart cities forever.
