You could ask for help from an Engineering School. Find schools at All Engineering Schools.
So what can you do with all this information? Here's some suggestions.
+ You could make and sell the device described in the expired patent. Please note that just because something is patented or written, it might not work all that well or might not be safe in today's standards. Use your own judgment, or seek help, to stay safe and out of trouble.
+ You could "translate" the expired patent into easy-to-understand instructions for others to make the device. These instructions could use easy-to-find materials, like trees, plants, rocks, people, scrap materials, etc.
+ You could recruit the inventors or authors to help you, since they are experts in their field. Some of the inventors of older patents might be retired now and might be looking for something to do.
+ Existing manufacturers of Cooling Devices could use this information to make their already fine products even better, more efficient, or less expensive.
+ You could use the information to brainstorm new ideas. Build on the work of others. Design around active patents.

So what can you do with all this information? Here's some suggestions.
+ You could make and sell the device described in the expired patent. Please note that just because something is patented or written, it might not work all that well or might not be safe in today's standards. Use your own judgment, or seek help, to stay safe and out of trouble.
+ You could "translate" the expired patent into easy-to-understand instructions for others to make the device. These instructions could use easy-to-find materials, like trees, plants, rocks, people, scrap materials, etc.
+ You could recruit the inventors or authors to help you, since they are experts in their field. Some of the inventors of older patents might be retired now and might be looking for something to do.
+ Existing manufacturers of "People-powered" Tools could use this information to make their already fine products even better, more efficient, or less expensive.
+ You could use the information to brainstorm new ideas. Build on the work of others.
Here's some brainstorming ticklers to help you launch in new directions around the topic of "People-powered" Tools.

That's about all for now. As background, the site "Design for the Other 90%" said to "GET INVOLVED", so I did. I plan to continue posting these LOW COST DESIGN TOPICS on my Blog for a while yet. Let me know if you have a topic you would like covered. I'm open to suggestions on improving my blog format, too. Please e-mail me directly.. I hope you find this helpful.
