Batteries are not just for charging and moving us around in our cars in the future. We're going to be using that stored energy and putting it back into the grid and fueling our homes electricity in the future with this technology. While this seems like it's quite far away we can also look at all the progress we've made in the last decade with new technology.

Michelin Tires has been working on Research & Development for 3D Printed tires. Since I have a background in this I found this particually cool. Very excited to see the future of tires and how it will disrupt the "Rim" industry and what new industries and jobs will be created when we have majority of tires being 3D printed vs. not. The only downside currently is the cost to make 3D printed tires as it will be a long time IMO when the cost of rubber tires exceeds the cost of 3D printed tires.
