The ROI for all the NASA investments
>Over 20 years ago when I started this project in researching bearings, we found the perfect solution: an all ceramic bearing created for use in satellites and spacecraft
>There was only one problem: when I first heard of these bearings, they cost tens of thousands of dollars and were only used in aerospace.
>...they have become more common and are now used in roller blades and fidget spinners and can cost as little as $10
