Please donate some of your time and build a solar concentrator in your community, based on designs present in this website, other website, or your own designs.
This is the best way to show the effectiveness, teach, and develop local solar concentration technology.
First hand demonstration of solar power is the best way to convince your friends, family, acquaintances, and people just walking by that local solar energy can solve many of our current problems; problems that are often considered unsolvable, such as widespread energy poverty in the world and the global economy’s wanton destruction of nature.
Though some theory might help also, there’s no replacement for seeing first hand a solar concentrator burst some wood into flames, or just cook some lunch, boil some water, make some bio-char (charcoal from wood) or steam, and contribute to your life in a general way (also making you less dependent on non-renewable energy sources).
After that the next big donation you could do is training others in your locality, or wherever you go.
You can also start some local projects to spread or develop solar concentration even further.
You could also donate some precious information and post some of your experiences and ideas here on the site thus helping and inspiring others far away that you may never even see or hear about.
