Is it me or is it just a metallic hot air balloon?
- spencerbeepboop 14y agoI concur. But it could be interesting to have hot-air balloon technology innovated.
- fusiongyro 14y agoHe has a FAQ entry about that: > With my device I bring the "cold parcel of air outside the balloon" inside my device.... The pressure difference between the the two parcels provides the force that lifts my device. By being able to bring the cold parcel of air inside my device two advantages are obtained over the hot air balloon. First, my device is not restricted to only moving in the atmosphere as is the hot air balloon.... Second, I am able to control how cold the cold parcel of air can get. Thus a greater pressure difference can be obtained which will in turn provide a much greater upward force. Sounds to me like he's essentially hooking up a fan to a sail boat like in a Looney Tunes cartoon.
