The Pigeon Printer Friendly Version
I had this idea of making a new high tech newspaper delivery system. I was watching this program on the history channel about homing pigeons and how they were used during WW1 to carry messgaes. Well I think the same thing can be done for newspaper delivery, but not using pigeons. It would be shaped as a pigeon and would carry at least twenty papers inside and will have a GPS system so it knows where to drop the paper. We would just have to figure out how to power the pigeon to fly.
Reward: Advice on how to make this.

Hellicopter Printer Friendly Version
OK, this may sound strange, but I had this vision of a man descending off a rugged mountain peak with an oak tree helicopter. Im sure you have seen them. they are those whirly birds leafy things that spin out of oak trees. My idea is, have a large scale replica of a oak tree hellicopter. Have the aerodynamics sufficiently flexible and proportioned to accomondate the passengers weight. Attach it to a race bearing located at the foot, or "seed" area of the "OTH" this would allow the helicopter to spin, but leave a stanionary passenger. The heavier the weight the faster the spin. The "OTH" would allow it's rider to gracefully and delicately float down to their destination. I think this would beat jumping off the roof with an umbrella. Hey how about a new sport!
Reward: Generous appreciation
