Well, sometimes the creative mind and creative geniuses allow themselves to engage in hyper creativity and imagination, at least I've been accused of this at our think tank. Therefore, the crazy idea I'm about to ask you to ponder will require that you suspend your belief system, and everything you think you know about physics in our physical world. Now then, let's begin because there may be a potential solution for a gravity interference scheme for high-speed rail and cargo trains. Let's talk.
When you see a train from a frontal view, you see the track and the wheels and a space underneath. No, I don't recommend that you get underneath the train lay on the track in the center to prove my point. Nevertheless, this creates a cavity with intense vibrational energy and sound. And therefore I ask; is it possible to use that energy to interfere with gravity waves. Whereas, it is true that we don't know much about gravity, at least we do believe it is a wave. If we disrupt that wave, we will limit the amount of gravity pulling down on the train.
Thus, it might be possible to do this underneath a train as it rolls down the track, we would be able to capture that vibrational energy, modify the frequency, and use it to disrupt gravity. By doing this the train would be lighter on the track, causing less friction. Less friction means less energy is needed to propel the train and therefore we can save fuel and economy, or use that power to generate more speed. Now then, what would keep the train from derailing? Perhaps a catch hook roller on the bottom of the track, which might mean we need to redesign the track ever so slightly, but it would be well worth the investment due to the amount of energy we would save.
One problem with this would be that by interfering with the gravity there would be less friction on the track, therefore less noise and vibration, thus, less energy to use to modify the frequency and power settings to counteract the gravity. Nevertheless we might be able to figure out on a graph exactly where the best and most efficient possible place might be between gravity and friction, coefficients of drag and weight of the train to dial in the best ratios.
Now then, I ask; what else might we use such a system for, and where else might we harness that level of energy to serve our needs in disrupting gravity? Such a system once perfected would seemingly have unlimited applications, not to mention it would help alleviate vibrational noise which is often an annoyance. Please consider all this and think on it.
