A quantum leap forward in air conditioning technology

A quantum leap forward in air conditioning technology.  “Refrigerators and air conditioners based on HFCs and HCs are also relatively inefficient,” said Dr. Xavier Moya of the University of Cambridge. “That’s important because refrigeration and air conditioning currently devour a fifth of the energy produced worldwide, and demand for cooling is only going up.” Eco-Friendly Solid Could Replace Conventional Refrigerants …

When Airplanes Are Designed To Be Energy Agnostic, You Know Electricity Is Banging At The Door

April 20th, 2019 by Nicolas Zart on Clean Technica The amount of breakthroughs and progress electric aviation has made this past decade are awe inspiring. We’ve got news practically every day of electric airplanes (e-planes) and electric vertical takeoff & landing (eVTOL) aircraft under development, planned for market, or already arriving. When you look back to long-off dreams of electric VTOL aircraft back …

We see the ongoing pernicious effects of the Doctrine of Discovery and colonialism in the continuing devastation that a capital-centered economy, with its extractive industries that destroy the air and water

We see the ongoing pernicious effects of the Doctrine of Discovery and colonialism in the continuing devastation that a capital-centered economy, with its extractive industries that destroy the air and water we all rely on for survival, threatens the very future of global humanity. The stakes could not be higher.  We had hoped the UN’s creation of the Permanent Forum and passage …

Then, changes to the tax structure distributed more and more of the wealth to the richest and hollowed out the middle class. Now, levels of inequality in the United States are unsustainable as the top one-tenth of one percent (0.1%) has wealth equal to the …

The US Office of Energy Efficiency and Renewable Energy cites several benefits to driving an electric vehicle of which the general public may not be aware

The US Office of Energy Efficiency and Renewable Energy cites several benefits to driving an electric vehicle of which the general public may not be aware. Because electric motors react quickly, EVs are very responsive and have very good torque. EVs are often more digitally connected than conventional vehicles, with many EV charging stations providing the option to control charging from a …
