Having just come back from a somewhat long business trip, I’m sure I would have found a use for one of these little units. According to their website, Inflight Power has developed an ingenious little attachment that can be plugged in to the audio jack on an airplane, and will convert that signal to power, usable for recharging USB powered electronic devices.

Modern flight relies on the ability of a plane to move fast enough for the wings to generate lift. In order to obtain and maintain the speed required for this lift, large engines consuming large amounts of fuel are required. But what if one were to create a plane that was lighter than air. This is exactly what Robert D. Hunt is attempting to build. Further to this, not only has this former nuclear designer attempted to build a “lighter than air” plane, but he is attempting to harness the power of gravity in order to maintain essentially fuel-less flight.

By increasing and decreasing the bouyancy of the aircraft, forward motion can be obtained first as the plane floats upwards, and then as the plane glides downwards. Hunt claims that using this method of flight will allow the aircraft to fly indefinately without the need for fuel.

The SkyKitten is a demonstration model of a helium filled, hybrid air vehicle capable of takeoff and landing in a variety of terrains. Produced by World SkyCat, these vehicles are capable of Vertical Takeoff and Landing and would be able to carry payloads ranging between 20 and 1000 tons. Read more about them here.
