Startups that will save our planet

(ORDO NEWS) — Companies around the world are now thinking about how to save the Earth from the global consequences of climate change. Someone manages to create large-scale projects, for example, to generate natural energy, while someone starts small – comes up with gadgets for growing plants.

We present you a “technical parade” of the most advanced inventions that will definitely make life easier for both man and nature.

3D printing is an easy way to build a park

The Chinese company AICT uses 3D printing technology to build houses, bridges and entire villages in the poorest regions of Africa.

And recently, AICT completed work on a whole park with an area of ​​​​more than 5500 square meters. m, which opened near the Shenzhen World Exhibition Center in Shenzhen.

The bushes, trees and grass cover are natural here, but the concrete structures, from the path cover to the benches, gazebos and sculptures, were created using 3D printers and industrial KUKA manipulators.

88% of the territory of the park is covered with greenery, and the rest of the space is filled with paths and structures printed on a 3D printer.

“Robotic technology enables more efficient use of labor, reduces construction time and overall cost ,” emphasizes the AICT website. “ Using 3D printers, we can build a medium-sized house in weeks, not months.

The park, which includes over 2,000 units, was completed in just 2.5 months and required several times less money than with traditional construction methods.”

Meat reactors

UC Berkeley-based startup Upside Foods is preparing to mass-produce artificial meat based on cell cultures grown in bioreactors.

A new $50 million campus is currently under construction in Emeryville, and an EPIC research and production center opened here at the end of 2021, which will be able to produce up to 200 tons of products per year.

It will be the largest line in the world, although Upside Foods’ competitors are right on its heels. The company has yet to obtain government approval to sell its synthetic meat, and until then, EPIC plans to host tasting tours.

The artificial meat market is growing rapidly and, according to McKinsey experts, by 2030 its volume will reach $ 25 billion.

Google Solar Panels

Nearly 100,000 small Dragonscale solar panels cover the roofs of Google’s new Silicon Valley buildings like shiny scales.

These batteries are made on a strong but resilient textured polyvinyl acetate (PVA) backing that also traps additional photons, allowing more electricity to be produced. The generation efficiency reaches 17%, which provides about 40% of the energy needs of Google’s new buildings.

Outside, each “flake” is protected by a 6 mm layer of toughened glass, and inside – Tedlar polyvinyl fluoride fireproof coating. During installation, the panels are overlapped, partially covering the lower ones, and hermetically connected to the neighboring ones, not letting water through even during heavy California rains.

Underwater kites for power generation

The Danish company SEV, which supplies electricity to the Faroe Islands, has begun testing a new power generation system, which was developed by Swedish engineers from Minesto.

For this, a pair of underwater kites with a wingspan of 5 m is used, attached to the bottom with 40-meter metal cables. The kites are set in a narrow fjord with strong undercurrents and are held on a tight cable, like kites that have decided to live under water.

Spinning turbines generate power, and a smart control system moves the kite to where the flow is faster. Experimental machines are capable of providing electricity to 50-70 average households each; in 2022, it is planned to deploy a more powerful modification, with 12-meter wings, with a capacity of up to 1.2 MW.

The population of isolated islands is only about 50 thousand people, but they require a lot of electricity: there are many fishing enterprises that need energy to process and freeze their products before sending them to the mainland.

What will flooded cities look like?

The Paris climate accords aim to keep global warming below 1.5°C. However, the measures taken today are not enough: if the situation continues to develop as it is now, the temperature will rise by more than 3 °C by the end of the century.

This will lead to sea level rise and flooding of coastal areas, which are home to 10% of the world’s population. The project of the Climate Central Foundation shows what the world’s attractions that risk being in the water will look like, including St. Petersburg’s Palace Square and Dubai’s skyscrapers.

Home greenhouse

Gone are the days when growing fresh herbs at home was the lot of pensioners. Today, this occupation has become fashionable and relevant, which is demonstrated by one of the premieres of the consumer electronics exhibition CES 2022 – the LG tiiun smart home greenhouse.

The system uses two shelves for six pots of ten plants each. Automation continuously maintains optimal temperature, humidity and lighting, allowing you to get one crop after another.

Growth can be monitored through the LG ThinQ mobile application, which will also warn you when you need to fill the irrigation tanks with fresh water.

Otherwise, LG tiiun is completely independent – the user only needs to harvest the crop in time and place new seeds on the shelf.
