This seems not to be a joke.

The Transportation Security Administration is interested in evaluating -- and eventually approving –- the design of certain laptop bags, so travelers would be permitted to pass through security checkpoints without having to remove their laptops.

[...]

To accomplish this, the TSA RFI pointed out that the laptop bag would need to meet the following requirements:

• The carrying bag cannot exceed any one of the proposed dimensions – 16 inches in height, 24 inches wide and 36 inches long.

• The materials that make up the bag cannot degrade the quality of the X-ray image of the laptop.

• No straps, pockets, zippers, handles or closures of the bag can interfere with the image of the laptop.

• No electronics, chargers, batteries, wires, paper products, pens or other contents of the bag can shield the image of the laptop.

TSA is inviting bag designers and manufacturers to come up with creative ways to meet these design requirements, but it has also suggested three concepts of its own:

• A bag that would open completely, and lie horizontally on the X-ray belt, such that one side with hold only the laptop.

• A bag that would open completely, leaving the laptop standing vertically, supported by clips.

• A bag that would pull apart in separate compartments, with one compartment containing only the laptop.

Doesn't sound like a particularly useful laptop bag.
