During the last three years I developed several ideas that will be interesting for engine drive (replace fossile fuel with powder out of renewable sources like grass), home generator (produce electrical power thru sun by using simple technologies like lenses and steam engine), Water vehicles (replace the common propeller as a drive with a simple power tube so that the drive has increased efficiency and is absolutely silent) and water desinfection (use easy available components to generate drinking water).
