Research and development from this channel has reached wikipedia, trams in Zurich, universities in Canada, England and Austria and nearly every country on the planet. A very wide range of topics are covered. Join in to validate this material. I have done lots of original experiments. Check out the playlists! You will find surprises in pretty much every video you watch here. Currently my main focus is a tracking parabolic solar cooker that is provisionally called the "Sun Scoop". It is operational on 10th May 2025, with bells and whistles to be added over the year.
