Gecko Feet Inspire Hand-Held Spider-Man Paddles
ygslash (893445) writes DARPA is developing hand-held paddles that can be used to scale vertical walls. The adhesion technology employed in the paddles is based on Van der Waals force, inspired by the feet of certain species of geckos known for their excellent climbing ability. In a recent test, a man weighing almost 100 kg (220 lbs) and carrying a heavy pack that added about 23 kg (50 lbs) of additional weight, was able to scale a vertical glass wall almost 8 m (25 ft) high using the paddles. However, the paddles are reported to be 'not battlefield-ready yet.'
Does 'not battlefield-ready yet' mean that grenades stick to the hand and won't let go? or mortar rounds, plane wings, tank tracks, pants...
The problem with trying to USE Van der Waals forces for anything is that in order to stick together, both surfaces must be microscopically smooth
Better not tell Geckos about that, they'll die out once they hear.
