<div>We have a proof of concept for a thermal refrigeration compressor which enables you to refrigerate using a 20 degree F temperature difference or more. This difference can be achieved from an attic and living area. People all over the world could refrigerate food for no more energy than approximately 1 Watt! That's less then a LED light bulb!
</div>
<div><br />
</div>
<div>Now that we have a proof of concept built at the University of Idaho, our next step is building a working product. We estimate about $4000 to get things started on building a functional machine (With the assistance of the University).  Any donations after that will go towards providing this and other inventions to the public which are described in the book, The Solar Solution by Mark Hall. We are working on starting an official non profit organization, however, going over the legal documents is arduous and expensive as we need help from a lawyer. 
</div>
<div>If you have doubts, that is understandable. Please checkout our website at <a href="https://www.asustainableearth.com" target="_blank" rel="noreferrer noopener">www.aSustainableEarth.com</a> for more details, or buy our newly published book $7.99 on nook, Kobo, street lib and several others. You can also purchase the book directly on our website. We made the book as easy to afford as possible for maximum availability.
</div>
<div><br />
</div>
<div>My goals overall — to explain practical solar and thermal energy principles in a clear, straightforward way that people can realistically apply to homes, small businesses, and communities. Some concepts are simple and immediately usable. Others are more complex and may require the help of a machinist, fabricator, or an entrepreneurial effort to bring them fully to life. A few designs may also require refinement and testing before they reach their full potential.
</div>
<div><br />
</div>
<div>I want to be transparent about that. This work is not polished marketing material — it is honest engineering knowledge shared openly, with the understanding that real-world innovation often improves through collaboration and iteration.
</div>
<div><br />
</div>
<div>All donations go directly toward helping build, test, and validate the systems described in the book. The first and most urgent priority is developing a ready-to-ship thermal refrigeration compressor system described in the first paragraph. Reliable refrigeration has the potential to preserve food, reduce waste, and improve quality of life at little to no ongoing energy cost beyond the materials used to build it.
</div>
<div><br />
</div>
<div>I want to help others gain the tools and knowledge to help themselves. I believe deeply that energy-saving and life-improving technologies should not be locked away, patented, or shelved to protect the status quo. I would rather earn nothing than see ideas with real humanitarian value disappear because they were bought and buried.
</div>
<div><br />
</div>
<div>If this work resonates with you, your support helps keep these ideas alive — not for profit, but for possibility.
