Homemade automated solar concentrator▲296
Hi HN! I quit my job two years ago to have more time to work on my side projects. The main one is an automated solar concentrator. I've just open-sourced it, it's not perfect nor finished, and I still have a lot of ideas for further development, but I'm interested in knowing what you think of it. There are many applications where concentrated solar power could be a viable environmental and economic solution, I hope this technology will one day be more widely used. Feel free to give any feedback and ask questions.
