Design Notes for Low Cost Solar Cooling

Hello All - This posting looks at designing "Low-Cost Solar Cooling". Some applications could be Refrigerators, Coolers, Air Conditioners, Garments, etc. - all using Solar Cooling in some form. Some uses for these applications might be helpful in cooling medical supplies, food, people, clinics, incubators, etc. Good Luck!


FYI - As a start, how about these old Solar Cooling 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.

To search for more Solar Cooling patents, try the following. Please remember that newer patents are probably not expired, and therefore active. In the Patent List above, look at the "Citations" and "Referenced by" of each of the patents that interest you the most. By doing this, you're essentially finding "more like this".



For a Worldwide search, go to esp@cenet.

1 - In the "International Patent Classification (IPC)" field, copy and paste in the following - f25

2 - In the "Keyword(s) in title or abstract" field, copy and paste in the following - solar* AND (refrigerat* OR (air AND condition*))

3 - Press SEARCH. View your results.

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 Solar Cooling 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.

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!
