How about a device that could take control of a airliner like a heat seeking or guided missile. In the event of a hijacking military jets could be deployed taking control of the jet and forcing it to land safely, brake and shut down.Reward: no more 9/11
Wouldn't it be nice if someone could produce a Portable Shopping Cart on the lines of a Twin Stroller. As a parent I sometimes find it frustrating loading the kids into the car and unloading the cart, then having to leave the cart at your parking spot, which is a big pet peeve of mine. It is also hard to find a cart that has a dry kid seat when it is raining.Reward: portable shopping cart or new twin stroller
There are compartments for smokers and non-smokers, there are even women's compartments. Now, why aren't there any compartments for kids?A lot of people (like myself) enjoy a peaceful train ride. They can do some work, read a book, or simply take a nap. However, all of this is suddenly over if a small child enters the place. I've experienced unbelievable scenes in the last years, including hours of hysterical screaming and provocative stomping around. One time I've even had a used diaper flung in my direction. The mother's only reaction was to be amused about how her little sweatheart had done the trick.Now, the point is, I really don't care how other people bring up their kids. However, most PARENTS have bad manners and don't realize that not everything their little ones might be doing is necessarily a treat to everybody else. The easiest solution would be to create kids' compartments. Everyone would benefit, most of all the children who would get a chance to play with other kids during the train ride, which would make their trip much more enjoyable.Reward: A free train ticket.
Perhaps if we can outfit submarine hulls with two layers instead of one, we might be able to cancel out the reflected waves. I have already measured out how thick the gap between the hulls should be: x(lambda)/4; where x is any odd integer. In this way, we will recieve reflection where the waves have the least energy, which is at the equilibrium.The first layer should be any kind of material able to transmit 66% of wave energy and reflect 33%. 66% of the wave energy is transferred into the gap between the hulls, where it is then reflected yet again through the first layer. This accounts for 66% of 66% of the initial wave energy. since it most nearly matches that of the originally reflected 33%, and since the spacing is correct so that dephasing might occur, most of the waves will be cancelled, creating a much, much weaker sonar signal. It might be small enough to even avoid detection by sonar systems aboard submarines. If no such material is available, perhaps ordinary steel with holes would work.Of course there is the significant problem of not knowing the wavelengths of the many thousands of sonar devices on submarines throughout the world. Reward: the navy's recognition of a feasible technology
Like magnetic poles repel each other, right?. What if we were to have pavements or "magnetic ways" that were the same magnetic pole as a magnetic skateboard. People will be able to hover and move by leaning forward and stop by leaning backwards.No fuel or energy is consumed either. Surely we could use this concept for motor vehicles on highways?Reward: I would like to be involved in the R&D if someone were to do this.
