#2852: BankBarrier

Today’s invention consists of two measures to make bank vaults even more secure.

The first is to place the hinge (red) inside the vault and to pressurise the interior, as in an airliner plug door. This makes any kind of externally applied force much less powerful in terms of opening the vault.

The second is to insert thermal tiles (orange), of the type used on the space shuttle, in the interior of the door (blue).

These are capable of resisting attack by eg thermal lance and, protected by the hardened steel skin of the door, cannot easily be mechanically or thermally punctured.

Anyone who succeeds in burning a penetrative hole into the vault would cause a jet of high pressure air to escape and ignite external equipment (or robbers).
