Claim:
1. A thermal protection system, relating to thermally protecting temperature sensitive goods, comprising: a vessel configured to contain the temperature sensitive goods; a stack of at least three thermoelectric modules thermally coupled to the vessel arranged electrically and thermally in series and configured such that each thermoelectric module within the stack simultaneously uses the Peltier effect, wherein the stack of at least three thermoelectric modules comprise a delta T that increases for each thermoelectric module in a first direction along the stack and an amount of heat transferred by the thermoelectric module (Qc) that increases for each thermoelectric module in a second direction opposite the first direction; an energy source coupled to the stack of at least three thermoelectric modules and configured to provide a current source simultaneously to each of the serially connected thermoelectric modules, thereby causing simultaneous use of the Peltier effect in each of the at least three thermoelectric modules; a heat sink coupled to the stack of at least three thermoelectric modules opposite the vessel; and a microcontroller operatively associated with the energy source to direct current from the energy source to the stack of at least three thermoelectric modules.
