The BMW IX Flow is covered with E ink which is the same material that is used on the Kindle. This allows the user to be able to change the color of the car to any color as long as it's a shade of gray. The E ink wrap is made of millions of microcapsules, which have the diameter of a human hair. The wrap contains negatively charged white pigments and positively charges black pigments. When an electrical current flows through the custom wrap on the outside of the car, it causes either white or black to rise up to the surface of a microcapsule. Diverse shades are achieved with different amounts of electrical current. click here
The BMW IX Flow is an all-electric car which means that the car is already pretty sustainable. If the user decides to, they can harness the power of the sun to use even less energy when driving. They could customize the color of the car according to the weather outside. In hot, sunny weather, the user could switch the car color to white which would mean that there would be less of a need for air conditioning since white reflects light. The same thing goes for cold weather, switching the car to black will absorb heat. Plus, it doesn't take any additional energy for the car to retain color because microcapsules only use energy when the current swaps their color. click here
The innovation doesn't stop at just one car. Currently an adjustable and flexible wrap is being worked on so that it could fit any car. However this will probably take lots of time and money since it has to be cheap enough for people to actually buy all the while being easy to install. This same thing is going on for objects. Imagine having something like a license plate that could potentially change colors on demand. With this new technology and other technology in general, people can express themself in so many more ways and it's only growing. click here
