I would write hundreds of pages about ecology, about purpose of our lifes, about the the world our children are going to inherit if we keep on doing as we do, but.... it's useless! People smarter then me have already written and proved everything what could be done, but only few listen. All others are blind and follow the herd to the road to ruin. Imagine, on the average every man on Earth burns equivalent of 2 tons of coal per year (to heat, drive, cool, cook and make products) and in our Slovenija about 5 tons. Most of this is taken from mineral oil and gas and will definitly keep on changing the climate. So, I just do what I have to do to sleep with an easy conscience and here are some results of this work: 

Our "solar house" a decade ago

and now (2016) - click the picture for the movie!

Our project of PHEV (plug in hybrid electric vehicle) E-espace

Some facts about the alternative energy resources - will biodiesel, hydrogen, photovoltaics, tide and wind save our way of life?

Solar cells on Aprilia Enjoy pedaltec electric bike. Why not?

I tested "bio diesel" made of vegetable oil. It works and we all should think of using it instead of fossile fuels. By that we do not hurt the nature or better we do hurt it by many other means, but at least less then the others. Unfortunatelly we consume too much fuels and if we would like to burn as much biodiesel as we burn mineral oil now, the Earth would be too small for the fields we would need.

Here is a sample of biodiesel fuel made of waste vegetable oil :
