FYI - Here's some information you might find useful in designing Low Cost Cooling Devices. As a start, how about these old Cooling Devices patents that have expired due to age (generally more than 20 years old from the filing date). Expired patents are free to use by anyone.EVAPORATIVE COOLERUS Pat. 271813 - Filed Jun 19, 1882EVAPORATIVE REFRIGERATORUS Pat. 568259 - Filed Dec 27, 1895COOLING BAGUS Pat. 1668598 - Filed Jan 30, 1926WATER BAGUS Pat. 1580705 - Filed Oct 13, 1934EVAPORATIVE REFRIGERATORUS Pat. 1174082 - Filed Sep 22, 1914EVAPORATION REFRIGERATORUS Pat. 1239250 - Filed Aug 19, 1916COOLERUS Pat. 1854070 - Filed Apr 9, 1930WATER COOLERUS Pat. 1960714 - Filed Apr 19, 1932
To search for more Cooling Devices patents, try the following. Please remember that newer patents are probably not expired, and therefore active.
For a Worldwide search, go to esp@cenet.
1 - In the "International Patent Classification (IPC)" field, copy and paste in the following - F28D5 OR F24F5
2 - In the "Keyword(s) in title or abstract" field, copy and paste in the following - (evaporativ* OR swamp* OR desert*) AND cool*
3 - Press SEARCH. View your results.
For the U.S. only, go to U.S. Issued Patents.
1- In the "Query" field, copy and paste in the following - (ccl/62/$ OR ccl/261/$) AND abst/((evaporativ$ OR swamp$ OR desert$) AND cool$)
2 - Press SEARCH. View your results.
For the latest in U.S. only, go to U.S. Published Applications.
1- In the "Query" field, paste in the same search string above.
2- Press SEARCH. View your results.

Find your local library and ask about Cooling Devices.
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.
Here's some brainstorming ticklers to help you launch in new directions around the topic of Cooling Devices.SURVIVAL STILL FOR OBTAINING POTABLE WATERUS Pat. 3436313 - Filed Oct 21, 1965Water producing apparatusUS Pat. 4365979 - Filed Sep 2, 1980

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. I'm sure you can do much better though! Good Luck!
