The US military is proposing to build a magnetic launch ring to put things into orbit (or at least, to lob them far up into the atmosphere). The payloads can be 220-pounds and will be released at 21,600-mph. This rules out the possibility of human launches, given that the payload will at some point be subjected to 10,000-gravities of force. Humans typically black out before 10-gravities.

Scientists have succeeded in creating a device envisioned by physicist James Maxwell more than 150 years ago called a Maxwell's Demon. The "demon" is a nanoscale device that captures molecules as they pass through in a particular direction when illuminated by light. This could lead to nanodevices that move by being irradiated with a laser because the molecule being captured imparts a force to the machine, causing it to move away from the now-captured molecule under the force of momentum.
