9. Eco-concrete
Eco-concrete is one of those technologies that has the power to transform our lives completely. This new type of concrete combines practicality, strength and air-purification. Air-pollution is one of the biggest problems people experience in big cities, making eco-concrete a modern day savior. It devours all kinds of pollution and eats smog by transforming harmful nitrogen oxide into nitrogenous compounds that aren’t so dangerous.
Holland was the first country to install this concrete and the results were impressive: eco-concrete eliminated over 45% of gases. Although this new type of concrete could do wonders for dozens of big cities, it is still too expensive for mass-production.
