An anonymous reader writes: NASA has released a bunch of patents for its technologies so that anyone can use them. A total of 56 “formerly-patented” technologies developed by the government are now available in the public domain, meaning they can be used for commercial purposes in an unrestricted manner. To make it easier to find these technologies and others like them, NASA has also created a new searchable database that links the public to thousands of the agency’s now-expired patents. According to NASA, the patents it has released may have non-aerospace applications that could help companies with commercial projects underway. Of the 56 formerly-patented technologies, users will find things like methods of propulsion, thrusters, rocket nozzles, advanced manufacturing processes, and more.
