how many recycled aluminium drinks cans would it take to build an aircraft?

Estimates using diet coke can:\n\n747 jumbo jet weighs 200 metric tons (assuming most of it is metal)\n\nCoke can weighs 10 grams\n\nSo a jumbo jet requires 200 metric tons = 200*1000*1000=200 million grams.\n\nHence it will take 20 million coke cans to make a jumbo jet

If the can holds EXACTLY 355 ml, with that many significant figures (3) this means that the contents can be between 354.5 ≤ n < 355.5  Any amount outside that range would be rounded off to either 354 or 356 ml (assuming scientific honesty on the part of the company).  Without a precision tolerance specification (e.g. ±.2ml) that is  the assumed precision.  If the amount was specified as 355.0, then the presumed tolerance would be ±.05ml.

Here are the instructions for building an actual NASA approved bottle rocket.\n\nI hope this is helpful!

You could consider reporting on the soon to be widespread use of CF (carbon fiber) to build giant airplanes and automobiles.  CF weighs much less than aluminum or steel and is stronger.  Reducing weight will save on fuel and will help enable the oncoming hydrogen/fuelcell cars.  CF also must be used in the larger wind turbine blades (about 300 ft in diameter) because it is light enough yet stiff enough to avoid bending and hitting the tower.  Also carbon nanotubes will provide the strongest CF if the cost can be reduced.

some cans are made of more than one material, for example steel coated in aluminum or zinc.  2 component cans are generally thicker than traditional cans

carbon more accurate cost more but as long as you don't break them which is hard to do they will last for ever wont bend unlike aluminum if you bend it..........It will never fly straight again

Cool, thanks so much for the idea. I believe that the space industry would love it.\n\nI have a few connections with Raytheon (formally Hughs Aircraft) and a few connection within the military. I will take my idea to them and see if I can get it started.

Attach a falcon to the prototype.. Think it will fly high! :-)

Depending where you live, rural or urban, but if rural then this gets it every time.  Aluminum cans all rinsed and shook out in one waste basket.  Steel cans and glass in another waste basket all rinsed and shook for avoiding flies.  Paper and plastics in the third trash can and collapse boxes and rinsed cartons and when this is full go burn it gone.  Aluminum cans give your children much appreciated monies and the steel and glass may be sorted if recycling in your social or society's preference: Glass here and steel cans there.  If somehow, baby diapers enter into the trash flow, then if you'll use double grocery bags you can nicely tie up a bundle of ten, no stink, and get em gone in some expedient manner: They burn badly and scatter owner's yard. Garbage can go to pet/s.

Yeah! Have you been reading the magazine Popular Science? I guess so. The flying cars have to be aero dynamic and there is a 50% chance that they would make it. Also NASA might build a supersonic plane from here to Tokyo in 2 hours. Isn't that amazing! I wonder if they could build that too.

106 kWh/t (avg) of electricity...but that isn't all the energy..there are other fuels consumed as well.\nThis site have what you need...\nhttp://www.world-aluminium.org/environment/lifecycle/lifecycle3.html\nand check out the pdf link under "Life Cycle Inventory data"  page 31
