How is the aluminium skin bonded to the frame of a cargo trailer without externally visible rivets or screws?

How can blockchain technology be applied in the cargo clearing procedures from the sea ports?
If you know exactly what is in every box inside the container and you have a perfect ledger trail of who bought what product from whom (verified known parties), there is no reason that the container should not be customs cleared at arrival port before the ship even clears departing port.Pretty much what happens right now with passengers on a flight from Riyadh to New York. But that’s 300 passengers.The problem is 300 boxes each in 20,000 (TEU-20) containers, a ship a day hitting the dock.Pro Forma = PO = Inv = Goods Insured = Terms Settled or Financed = Bill of Lading = Insurance for Delay Business Loss = Unloading = Customs Clearance and Tarrifs =Surface FreightNo reason Custom’s bit cannot be pre-cleared with known freight carriers between known transacting parties.
If you fill the entire 747 cabin and cargo space with Tesla batteries and engine, would it have enough power to fly and how far could it fly?
As far as I can tell, the cargo hold capacity of a 747–400 is around 750 cubic metres, or 750,000 litres. The size of an 18650 cell, as used by Tesla, is 65.2 mm long by 18.5 mm diameter. Rounding it up to a cuboid, you get a volume of 22.3 ml, or 0.0223 litres. so the 747 will carry about 33 million cells. They weigh about 45 gm each, so the total weight is in the region of 1500 tons. The payload of a 747 is about 160 tons, so your plane is never going to get off the ground.
