Robot That Plants and Weeds Promises to Revolutionize the World of Renewable Energy in Agriculture

Renewable Energy: Solar-Powered Weeding Robot Has Capacity to Work 24H Without Recharging. Currently, There Are Over 50 of Them Spread Across Europe

Currently, the world is trying to drastically reduce the emission of polluting gases. Aiming to revolutionize the world of renewable energy in agriculture, many scientific projects are being developed to reduce the size of machines, extend the level of automation, and, no less importantly, utilize solar energy to harm the environment less and less. To this end, a solar-powered robot that plants and weeds has been developed, capable of cutting weeds with precision and carefully tilling the soil between rows of delicate plants.

The new weeding robot was created by the company Farmdroid and is recommended for crops of up to 20 hectares in organic farming. In this context, weeding also helps reduce the use of chemicals and pesticides.

And it doesn’t stop there; the seeding uses GPS technology to determine the position of each seed individually. Additionally, the equipment operates with four solar panels and external batteries, allowing the robot to work 24H without the need for recharging.

Currently, there are over 50 solar-powered weeding robots functioning in six countries across Europe. If you are considering acquiring one, you will need to shell out about R$427,000. Think it’s expensive? The developers assure that, at most, after two years of using the model, the owner will already see a return on investment.

Bladeless Turbines Could Revolutionize Wind Farms and Change the World of Renewable Energy

Vortex Bladeless, a technology startup based in Spain, is developing wind energy turbines that do not require blades (or propellers). One of the goals is to be able to use these turbines in urban and residential spaces, where the impact of ecological parks would be too large, as they do not threaten bird migration patterns or wildlife.

Resembling a “giant straw,” the bladeless turbines, according to their creators, came to change the world of renewable energy.

The appearance may be misleading, but even without propellers, the Vortex can convert breezes into energy, but in a different way. Instead of using the circular motion that blades create, the new turbine utilizes what is called vorticity, an aerodynamic effect that produces a pattern of swirling vortices. Vorticity has been considered the biggest enemy of architects and engineers, who try their best to work around these wind whirlpools in certain types of constructions. However, the founders of Vortex Bladeless, David Suriol, David Yáñez, and Raul Martín, saw this as an opportunity.
