Denver will be home to North America’s largest sewer heat-recovery project
Did you know that the hot water you send down the drain can be used to regulate the temperature of buildings? Called sewer heat recovery, the process essentially captures warm water from showers, washing machines, and dishwashing and stores it in a heat-consistent pit. This stored water is then Read More...
Papilio is a self-powered street lamp designed to reduce light pollution
Human innovation has driven our civilizations forward, but oftentimes at the detriment of other species. For instance, conventional lights and street lamps allow people to work and navigate at night, but they can confuse nocturnal life and attract pollinators, killing them in the process. Tobias Read More...
Fluorescent dye can help determine when to replace your car's electric motor
The age of the electric vehicle is upon us, but with this new era comes a learning curve as we figure out how electric motors function over time. While many studies show that electric cars require less maintenance than their gas-powered counterparts, they are still prone to wear and Read More...
Sustainable and beautiful "tulip turbines" pop up just in time for spring
Here at The Optimist Daily, we are big fans of wind energy as a renewable and sustainable source of power—but that’s not to say that it doesn’t come with a few downfalls. Wind energy requires wind turbines to convert kinetic energy into electricity. These turbines generate noise pollution, Read More...
Harvard researchers uncover breakthrough in lithium-metal battery efficiency
Researchers at Harvard University’s School of Engineering and Applied Science have discovered what is being referred to as the “holy grail” of battery breakthroughs, solving a 40-year quest for a fast-charging, long-lasting electric vehicle battery. The newly developed lithium-metal Read More...
Top wind energy company develops fully recyclable blade technology
Wind energy is a key pillar in our renewable energy future, but even green technologies have some drawbacks. EV batteries need to eventually be recycled and wind turbines can interfere with bird populations and produce waste as well. In an effort to address one of these critical issues, wind Read More...
North Sailing offers Iceland's first carbon-neutral silent whale-watching tours
Much of the ocean remains a vast mystery to us land-dwellers, however, advancements in research and aquatic observation are pushing us towards a greater understanding of marine creatures and their environments. One of these budding areas of study is the way in which noise pollution impacts life Read More...
This offshore floating solar platform can withstand hurricane winds
As the threat of climate change intensifies, countries are beginning to take a serious look at the logistics of stepping away from fossil fuels and towards renewable energy sources. Building offshore renewable energy infrastructure is a key aspect of this transition, and engineers are now working Read More...
Heineken is turning wasted beer into sustainable energy
When the pandemic forced us into lockdown, many of our favorite watering pubs, bars, and restaurants had to throw out millions of dollars of stock. In the UK, the British Beer and Pub Association (BBPA) estimates that about 87 million pints of beer have been tossed as a result. Fortunately, the Read More...
