The issue of global warming is complex and ever-changing, and has been evolving from the world’s biggest problem to the world’s biggest opportunity for innovation. While world leaders and government officials attend international summits to discuss how to combat rising CO2 levels, entrepreneurs all over the world are designing and creating sustainable technologies to help clean up the environment.
In this week’s tech trends, we’ll learn about efforts taken all over the world to reduce waste and clean the environment while inspiring others to innovate new green technologies.
Narayana Peesapaty created edible spoons in Hyderabad, India to reduce non-recyclable waste. The edible cutlery is a bio-degradable option that has a shelf life of three years and decomposes within four-five days if not used. The utensils even come in three different flavors to best fit the food with which they are served: plain, sweet, or spicy.
Ari Jónsson uses algae to create biodegradable water bottles – Dezeen Magazine
Ari Jónsson, a product design student at the Iceland Academy of Arts, has used agar - a substance made from algae – to create a biodegradable bottle. When agar powder is added to water, it forms a jelly-like material, which Jónsson used to make the bottle. As long as the bottle is full of water, it keeps its shape, but as soon as it is empty, it will begin to decompose.
These Jiggling Bladeless Turbines Are A Breath Of Fresh Air – Huffington Post
Wind turbines are one of the most popular technologies for creating clean, sustainable energy by converting kinetic wind energy into electricity via a rotating blade system inspired by 7th-century windmills. However, critics have noted hazards that turbines present to birds and bats. A Spanish company called Vortex Bladeless has developed turbines without blades that generate electricity by jiggling. These bladeless turbines are less expensive, take up less room, and have a smaller carbon footprint than traditional turbines.
How a giant air freshener could save our polluted cities – The Guardian
After witnessing six-year-old children in Beijing with lung cancer, entrepreneur Daan Roosegaarde created the idea of a smog-free tower. The smog-free tower acts as a giant vacuum cleaner that cleanses harmful particles out of the air by filtering toxic materials to pump out 75% cleaner air. A seven-meter-high version of the tower exists in Rotterdam, and authorities in Beijing have purchased the technology to replicate the towers in multiple cities across China.
While most greenhouse gas efforts aim to reduce emissions, Carbon Engineering Ltd. has created plants that convert CO2 into a renewable liquid fuel. Carbon Engineering’s technology differs by targeting greenhouse gases emitted from smaller sources such as cars, ships, and airplanes. Carbon Engineering’s plants can be located virtually anywhere around the globe. If the current pilot of these plants performs well, expansion on an industrial-scale operation is the goal.
