What if an unfathomably hot, never-ending, never-varying heat source existed that could be harnessed for energy production? This heat source does exist. Right beneath our feet. The top of the Earth’s mantle hovers around 1000 degrees celsius, achieving access to it would make the efficiency of all other current energy sources pale by comparison. With …

Charlie Wilson, University of East Anglia; Caroline Zimm, International Institute for Applied Systems Analysis (IIASA), and Simon De Stercke, Imperial College London Massive amounts of public money are being mobilised to kickstart economies out of COVID-induced recessions. Many countries are allocating parts of their stimulus packages towards ensuring the recovery is green.
Today’s silicon solar panels are an industry standard, but these rigid, heavy blocks may be shunted aside by plastic rivals – lightweight, flexible solar panels that could be printed and stuck onto buildings or placed in windows or cars, turning light into electricity in locations inaccessible to their heavier cousins. The standard solar panels we …

When we think “home maintenance,” we often dread the tedious work and costly repairs that come with these tasks. There are many times when we have old things in our homes, and some of these can cause major problems down the line. We often look at these things and end up deciding to scrap it …
New York-based scientists have achieved the room-temperature superconductivity for the first time, using a hydrogen, carbon, and sulfur compound. According to the study published in Nature, the new compound operates as a superconductor at up to 15 °C (59 °F) at very high pressure (267 GPa between a pair of diamond anvils – that’s about …

People are starting to build more eco-conscious residences, and zero-net-energy homes are becoming increasingly popular. They can be designed in any style or size, connect to a traditional power grid, and are suitable in all climates. Their versatility makes them incredibly attractive, especially to those looking to save on their utility bills.
It turns out that when it comes to saving the planet, you don’t have to trade in your gas-powered car or even shell out a bunch of cash – you can do it right from the comfort of your own home. In fact, making a few small upgrades to your home and tweaking your everyday …

In recent decades, consumer and commercial technologies have developed so rapidly, so expansively, that those of us who came of age prior to the digital revolution would hardly recognize the world today if we hadn’t experienced it. Those of us old enough to remember the 1990s could never have anticipated how today’s technologies would infiltrate …
As per the report by the United States Department of Energy (DoE), an average household in the US uses 90 million BTUs of energy per year. Out of this, most energy is wasted due to lack of insulation, air leakages, lights being left on and other such practices. With global warming being a major concern, …
