Physicists have found the formula for a human spider suit. Like spiders and geckos, these new suits will use adhesive forces to support human weight. Van der Waals forces are weak attractions between molecules that are very close together. These forces are what keep spiders clinging to walls. Both van der Waals and tiny hooks attached to [...]

Magnetic Refrigeration and Air Conditioning
June 1st, 2009 · No Comments · Physics
Scientists are even closer to making magnetic refrigerators and air conditioning systems. This technology would greatly decrease our country’s demanding usage of electricity. This invention would use 20-30% less energy than the current machines. This all works by applying a magnetic field to a magnetic material, causing it to become hotter. The extra heat is [...]

Space Elevator
June 1st, 2009 · No Comments · Physics
Physicists have discovered a new way of getting to space. They believe that they can use many strings in an eliptical shape to raise objects up into space. This space elevator wouldn’t even need any type of engine propulsion. It would use the earth’s rotation and the string system alone. This could be a great advancement [...]
