Not that you care, but I'm sure in the realm of minecarts in the game Minecraft my bi-directional double booster will be all the rage. It can even be made into a uni-directional quadbooster giving a person 40 track lengths of boost in only 37 units of track. With an additional 4 units of boost for each additional 3 units of track. It gives better than a 1:1 track to boost ratio. At best the alternative boosters are either unidirectional 1:1 boosts (assuming you use it inline with already existing track, or bidirection 2:1 (with rather marked overhead) at best. Further, all previous bidirectional boosters used two additional minecarts for boosts, and were really direction parsed parallel unidirectional boosters. My design needs only one additional minecart, even in quadboosting mode. My design can get about a better than a 1:1 ratio and work in a bidirectional fashion. Or if you don't need bi-directionality, it can be reflipped to quad boost. Because super-efficient construction things in a sandbox game are all the rage.
(this should work after the video is processed one would think)
