Hydrogen is an energy efficient,greener and replaceable solution of fossil fuels. According to research Aviation industries produces more carbon emission. I have designed basic POC to develop such a aviation product which can powered by Hydrogen fuel cell or other method to convert hydrogen energy into an Electrical or mechanical energy. To apply this method i have designed small scale VTOL drone which will utilized hydrogen energy to power this drone. By using hydrogen energy and VTOL technology we can achieve long endurance of drone. With the use of Hydrogen cell and Solar cell we can increase more efficiency of commercial Aviation transportation.
