Electric Propulsion Reality Check

FWIW regarding a very minor point in the energy consumption discussion: Our refrigerator has a two-drawer freezer section at the bottom, so very little cold air is lost when pulling out either drawer to access the items. After opening the main refrigerator section's single door, what you see is at least one-half of the volume consisting of individual drawers that you have to pull out and reach down into for access to the items, keeping cold air loss at a minimum within each drawer.

But ... the refrigerator was not inexpensive and was built by an Austrian company. Leave it up to Europe to have it all together - since they learned long ago about the long term effects of population levels versus energy (and food and lumber) consumption.
