How Technology could Save the World

I get it. We are all worried. Greenhouse gasses, global warming, plastic in the oceans, pollution and so on. Every day we are forced to acknowledge the fact that we only have limited resources and we have done significant harm to Mother Earth. Here are some positive things to think about.

1.       Aquaponics – Using waste (and fish) to grow food

This is a complicated system but I will break it down as much as possible for you. Usually when fish and other aquatic animals are farmed there is a buildup of waste from the animals being farmed. This can increase toxicity. Using a complicated system, this waste is broken down into nitrates and the waste is used as nutrients to plants and vegetables. The water is then cycled back into the fish tanks for reuse.

This is great because it conserves water by recycling the water already in the system. No harmful chemicals or fertilizers are used, meaning less contamination. Less energy is used than conventional farming and the growth rate is six times more than commercial farms (per square foot) meaning less land is being used and these farms can be set up almost anywhere.

2.       Seabin

Full skip of waste

Seabin is a floating bin that filters water in docks and lakes and catches any rubbish that has been littered. It sucks in contaminated water and filters it through a ‘catch bag’. Clean water is then pumped out of the other side, leaving the debris trapped. At the moment these systems can only be used in calm waters like docks and marinas.

We have all seen videos of sea turtles and fish caught in plastic bags and other rubbish that had been littered into our oceans. Even cleaning a small amount of debris away makes a difference.

3.       AIR-INK

We all understand that air pollution is bad for us, it is the result of years of burning fossil fuels and the particles in the air can cause respiratory problems and ultimately death. Well, one company is using that pollution to create something beautiful. They use soot collected from the air to make ink that is safe for us to use.

A filtering system is connected to the exhaust pipe of diesel engines and captures the exhaust fumes released.

AIR-INK is not available for purchase by consumers yet, there is a rigorous testing process before it can be bought to market. When this is bought to market though, it will be an excellent way of reducing air pollution and will also prevent additional fossil fuels being used to create normal ink.

4.       Solar Glass


Creating power that is sustainable is a tricky business. It would be impossible to run the world using power from wind farms, there isn’t enough space to host the wind turbines that would be required. There is one solution though, solar glass. Each window would collect light to be converted into electricity, we could (potentially) completely banish crude oils and fossil fuels.

5.       Water from Human Waste

The Janicki Omni Processor literally turns poop into fresh drinking water. With 7.6 billion people on the planet, we certainly have enough human waste to spare. 1.1 billion people on the planet do not have access to safe drinking water and every year millions of people die because of diseases spread through contaminated water.
