bernat has long been interested in energy and how to produce it it's something he's taught himself a lot about over the years he developed this machine to flatten flexible cubes to drip irrigation. as an inventor it's your job to come up with something useful. i realize that people were ignoring the environment even though it's of central importance to human beings. so i began developing ideas that will make a difference to the environment. he started at home by using wind to generate electricity this turbine powers his homemade washing machine the water is pumped up from a borehole it's not only environmentally friendly but also saves time and effort if there's no wind he can always hop on this bike can pump the water up that way. he's also had a solar panel installed on the roof so he's no longer dependent on the state power grid. bernard is not alone with his passion for inventing a few years ago he and some friends set up an innovation hub called 20 day in a russia the inventors come to this workshop to develop ideas and build products like this wheelchair made from discarded obj
