I looked into fuel cells, but this was only tested on the single engine diamond aircraft where they saved 5% of fuel consumption..i also looked into shark sythetic material which is currently being used on ships and they're trying to transfer it to aircrafts...same thing, it reduces fuel consumption because of less drag on the aircraft's body, by 5% too. With regards to the actual shape of the aircraft....i didn't look into that yet. I just need to make sure that whatever i choose has got to do with renewable stuff, but still related to engineering. Thats where the problem comes in as, once ive done research i need to test my theory, so...cant pick something in which i need millions to create a prototpe
Ohhhh...this is going to be a horrid year :P
