I want to invent the filter portal. The filter portal can filter anything out of anything.
If it filters bad bacteria, it can cure people with Ebola, HIV, and cancer by detecting abnormal cells, protein, or DNA. It can also purify air, water, and land pollution.
My plan is to have a laser emitter with very fine beams aligned together forming a sheet of laser. It will be mounted on the ceiling with the detector on the ground. As the objects or people pass through the sheet of laser, unwanted organisms and cells are detected instantly. When the cells are detected, they are microscopically disintegrated to be disposed naturally.
I think my invention will have a great impact on the world's health and the prevention of catastrophic disease and pollution.
