1. Breathing Bike
Artist Matt Hope has created an ingenious pedal-powered air filtration system that provides clean air to the rider as it moves. Using an IKEA perforated garbage can, moped helmet, fighter-pilot breathing mask, wheel-powered generator, and home air filtration system, the entire contraption uses human energy to clear the air. The city like Beijing, where the air pollution rate hit the record high, Breathing bike might help the citizens from a health issue when riding.
2. Smog eating street
Scientists from Eindhoven University of Technology installed smog-eating concrete onto a city block in Hengelo, Netherlands, finding that in ideal weather, it could reduce air pollution by up to 45 percent.The researchers coated one part of the street with titanium oxide — a photocatalytic material known for its air purifying qualities — and another part of the street was paved with normal paving blocks to act as a "control street." The parameters measured included traffic intensity and nitric oxide, nitrogen oxide and ozone concentrations.The study found that the nitrogen oxide air pollution was decreased by 19 percent over an entire day.Although the titanium-oxide coated pavement is around 50 percent more expensive than normal concrete, the researchers believe it could be a very feasible solution for inner city areas where they have a problem with air pollution.
3. Concrete canvas shelters
Concrete Canvas Shelters(CCS) are rapidly deployable hardened shelters that require only water and air for construction. A CCS25 variant can be deployed by 2 people without any training in under an hour and is ready to use in only 24 hours. Essentially, CCS are inflatable concrete buildings. CCS have a range of applications in both civil and military sectors, as emergency key infrastructure for disaster relief or frontline operations.
As what we have seen from the movies become reality, I hope those inventions will be part of our lives in the near future.
