(Ideas since childhood)

Atomic fusion
We are at an age where 3D printing is incredible, and that we even use it for medical science. But let’s take that technology one step forward. Atomic fusion to create different atomic bonds to create minerals and other resources that we use. Instead of digging up the earth for minerals that are slowly proving that we need to either find another planet to gain minerals or the minerals goes to the highest bidder. But if we’re able to create the minerals we need by just fusing atoms together and creating a better and longer lasting mineral than we could let our other resources take time to produce more in the long run.
Our sun, our brains all create chemical reactions naturally, but what if we take atoms from the very air we breathe in, which contains almost every element we need to create the resource we need, and transform it into a more useful and beneficial product. For humanity sake, if we plan to keep the human race living on a dying world we need a different resources that could never be depleted in short period of time. Science Fiction as always been called fiction until a true believer takes the idea and makes it real.

Water Purification
In a time where water has become a major issue isn’t that a real solution without destroying ones’ own living style? Like purifying water and other liquids to be reused. Image 2 small ball, no big that a golf ball, one black and the other white. The black one is use to trap all types of waste produce that any water might have, and the white ball traps the black ball into a seal and the water is then clean. Let me give you an example.
Let’s sad you have a clean bathtub of water. You’re cover in unwanted hair, scars, acne and you wish your body was completely clean of every mark. So you drop the black ball into the water, which then dissolves and turns the water black and almost like liquid rubber. You take a dip, cover every inch you want clean. Just because you like taking baths you stay in for a while. When you’re about to exit the tub you drop in the white ball. Before your eyes everything that was cover in black liquid is sucked by this white ball. Before your eyes not only is the water so clean it makes it seem you never took a bath, but also everything you wanted off your skin is gone and you’re left with clean skin. Now all you have to do is get rid of the white ball, or you could store it for your next bath. With this you never have to change the water in the tub, you just have to heat it up when you want a hot bath. Also this same water can be used for a shower and just clean the water again after is collects in a holding tank.
The point is that these balls help us RECYCLE WATER.
