Engineering has been a huge boon for the safety and comfort of mankind. A lot of recent advancement have already proved to be highly effective for easing our way in this modern world. A few recent inventions have a great use in cleaning the trash of our world with much less effort and time. They can also be said to mitigate the effects of climate change in the world.

The floating vacuum: It is a simple sea bin which sucks up trash from the sea. It traps the waste and debris of the sea and then pumps the water back up. It is totally safe for fish and it also catches oil and pollutants.

The massive air filter: Now it is an amazing invention. It is the world's first commercial carbon removal plant.  This air filter can absorb carbon dioxide from the atmosphere and this CO2 is then pumped in a sealed green house to hasten the growth of the plants. It can trap 900 million ton of CO2 per year which is equivalent to the CO2 produced by a drive for two million mile. This stacked up CO2 can also be used to produce beverage, concrete and cement.

Mr. Trash wheel: It is a solar powered boat that has removed over 1 million tons of trash from the Baltimore harbor. It runs on 100% renewable energy and the water powers its wheels which has been removing tons of plastic bags, styrofoams and beer bottles. This collected trash is incinerated and the energy generated is used to power homes in Maryland. It is also safe for aquatic fishes.
