Historic Vertical Axis Wind Machines: Lessons for Sustainable Energy

By | | , ,
Leave a comment

Most people are familiar with horizontal axis wind machines. These include the charming Dutch and Danish water pumping machines, the smaller sail windmills of Portugal, Greece and other areas, the iconic multi-blade water pumpers of the American west (millions sold), and the ever larger and more expensive three-blade wind turbines being used around the world to generate electricity. Hundreds of different wind machine designs have been proposed, built and tested and innovation continues to this day. The vertical axis wind machines are less well known. These had been invented and refined hundreds of years before the horizontal axis machines. Two … Continue reading →

Persian Wheel for Lifting Water – Another Ancient Innovation

By | | , ,
Leave a comment

Lifting water can increase the area that can be farmed, improve agricultural productivity, and provide drinking water. A Persian Wheel lifts water with animal or human power when there is insufficient flow for a noria. The animal energy was often supplied by a team of oxen. The Persian wheel may have been invented in Persia, Egypt, Kush (Sudan), Nubia, India, or even China. The earliest reference is found in the Panchatantra (c. 3rd century BCE), where it was known as an araghaṭṭa a combination of the words ara (spoked wheel) and ghaṭṭa “pot” in Sanskrit. Early Mediterranean evidence of a … Continue reading →

As the long-term impact of COVID-19 on the global economy is becoming more clear, many people around the world are at particular risk of homelessness. The spiraling inflation and growing unemployment are making life very difficult for people as prices of basic food items and utility bills are getting out of the reach of poor people. On the other hand, people are losing jobs or finding it hard to enter into labour market due to multiple social and economic reasons. With the result, there is a steady rise in homelessness which is going to increase in coming years. As per … Continue reading →

Modern cities need buildings that stand tall without pushing the planet down. Green structural engineering responds with fresh ideas that trim carbon, save energy, and hold their own against storms and quakes. Below are ten breakthroughs reshaping blueprints today. Each section explains the idea in plain language, highlights its benefits, and shows how designers already use it in real projects. 1. Carbon-Negative Concrete Concrete frames the world’s homes, bridges, and tunnels, but regular cement production releases massive carbon. New carbon-negative mixes flip the story. Plant minerals, captured CO₂, and even seawater waste become part of the binder. When the mix … Continue reading →

The Case for Renewables-Powered Desalination in MENA

By | | , ,
16 Comments

Desalination is a water treatment process that separates salts from saline water to produce potable water. The desalination process uses large amount of energy to produce pure water from saltwater source, such as seawater. Saltwater is fed into the process, and the result is an output stream of pure water and another stream of waster with high salt concentration. Desalination techniques are mainly classified into two types: Processes based on physical change in the state of the water, and Processes using a membrane that employ the concept of filtration. There are more than 20,000 industrial-scale desalination units worldwide, with combined … Continue reading →

Laboratories play a leading role in solving difficult global challenges. These include health, agriculture, and climate problems. But traditional research practices can create their own issues. Labs often consume large amounts of plastic, energy, and chemicals. These habits produce waste and raise environmental concerns. Many scientists are now looking for cleaner, more sustainable solutions. One promising answer lies in miniaturization. Smaller assays now allow scientists to reduce waste and save costs. They also bring more flexibility into the research process. These tools are changing how labs operate from the ground up. They encourage sustainability without lowering the quality of science. … Continue reading →
