The search to build the first hoverboard that will operate much like the one in the Hollywood Movie – “Back to the Future” is an on-going dream of many technology buffs. The race is on to come up with the concept and technology to produce a real life version.Well, we know that batteries weigh a lot, but using a “hovercraft” type strategy, the weight is not a big issue, as long as you can trap the air and hold onto it. Hovering on a flat surface helps, but you cannot do many tricks or you lose your air underneath. There might be a way to solve that problem with an expandable skirt and some ground affect soft landings.
Perhaps, you could use a battery system, the lighter the better. But, also realize that the electric motor scooters are some 400 lbs and only able to do what an 80cc motor can do. Now then, it does not take very much energy to blow 2 Lbs of low pressure under the hoverboard, so you do not need a lot of power.If you use the ram air from the forward momentum to help, then you need less power and have more hovering ability as you go faster, allowing you to go slightly higher. The big issue is when you let the air escape it is like a giant waste gate and the hoverboard will land.
There have been hoverboard tout terrain built that can go down the road at 60 mph, an old NASA rocket scientist built one once and he use to drive it around the Valley, a Los Angeles suburb. Basically his hover-car, looked like a little flying saucer, had little friction on the ground as they do not touch the ground, but his had wheels underneath for steering and stopping.Remember on a skateboard we want to catch air, but if you are merely looking for a skateboard to work like a hovercraft, sure we can build one and use some extra tricks to make it perform, but, will it be fun to ride, can you do tricks? But I think Christopher is onto something here, why not build a battery powered hoverboard, I want one too.
