About & contact

My name is Krzysztof Lis, I am 27 years old, I live in Poland. On october 2007 I graduated Warsaw University of Technology, Faculty of Power and Aeronautical Engineering, with M.Sc. diploma.

This site is an english version of my site Drewno Zamiast, dedicated to alternative engine fuels (biodiesel, bioethanol, and wood gas), renewable energy sources, and autonomous buildings. When I find free time I’ll post some articles here.

This is not an exact mirror of the polish site. I started this site as an WordPress blog to concentrate on its contents, not on its looks.

Please note that I’m not english native and use english as a foreign language. I apologize for any mistakes, errors and stuff like that, but am afraid I won’t be able to avoid them all. If you find any error that makes text non-understandable, please contact me!
