Solar paint offers endless energy from water vapor

Researchers have developed a solar paint that can absorb water vapour and split it to generate hydrogen – the cleanest source of energy. The paint contains a newly developed compound that acts like silica gel, which is used in sachets to absorb moisture and keep food, medicines and electronics fresh and dry. But unlike silica

All Dutch trains now run on 100% wind power

As of the first of January this year, all public transport trains in the Netherlands are being powered by renewable energy, namely from wind power. There's currently a total of 2,200 wind turbines across the country, which generate enough power to sustain the equivalent of 2.4 million homes. Initially, trains in the Netherlands were set

This Tiny Device Could Provide Clean Water for 663 Million People

A tiny, black rectangular device could be the world’s long-term solution for clean water.  The gadget is solar-powered, half the size of a postage stamp, and it disinfects water. “Our device looks like a little rectangle of black glass,” said Chong Liu, lead author of a paper on the device published in Nature Nanotechnology. “We just

Water harvesting from air with metal-organic frameworks powered by natural sunlight

The prototype, designed by scientists at MIT and the University of California, works even in desert conditions and could eventually provide households with all the drinkable water they need, simply by extracting dampness from the surrounding atmosphere. The solar-powered harvester can provide 2.8 litres of water from the air over a 12 hour period in

Growing Up: Vertical Farms Evolve to End Hunger

Cinder-block walls still bear Day-Glo paint murals inside the former laser tag arena that once hosted epic battles among New Jersey teens who breathlessly chased each other in a high-tech version of the incredibly low-tech game of tag. Nowadays, AeroFarms has taken over the cavernous building to operate one of the country’s biggest vertical farms.

Just Press Print: 3-D Printing At Home Saves Cash

Interested in making an investment that promises a 100 percent return on your money, and then some? Buy a low-cost, open-source 3-D printer, plug it in and print household items. In a recent study published in Technologies (DOI: 10.3390/technologies5010007), Michigan Technological University Associate Professor Joshua Pearce set out to determine how practical and cost effective

Newly engineered material can cool roofs, structures with zero energy consumption

A team of University of Colorado Boulder engineers has developed a scalable manufactured metamaterial — an engineered material with extraordinary properties not found in nature — to act as a kind of air conditioning system for structures. It has the ability to cool objects even under direct sunlight with zero energy and water consumption. When applied

Lighting Up Lingshed: A Remote Village in the Himalayas Gets Lights and Internet Access

About half of the population of the Himalayas has no access to electricity. Until recently, the 700 residents of Lingshed village were among them. Located in the Ladakh region of the Himalayas, the remote village is nearly a day's trek from the nearest road, which itself is impassable during the long winter months. In August 2016, a

Why Europe is leading on climate-conscious business

In other countries, corporate sustainability is not about the bottom line as much as mutual responsibility for the future. I know the topics and content at European conferences are different from events in the states because I’ve attended equally self-selecting green business conferences across America, such as VERGE, Sustainable Brands and Sustainable Purchasing Summit. At these

10 Companies Going Zero Waste to Landfill

With the start of the new year, business leaders around the world are contemplating how to take their companies to the next level when it comes to sustainability. And despite what’s happening in Washington, American businesses are rising the occasion — cutting carbon emissions, conserving water and energy, and engaging employees around their goals. If

Clean-Energy Jobs Surpass Oil Drilling for First Time in U.S.

The number of U.S. jobs in solar energy overtook those in oil and natural gas extraction for the first time last year, helping drive a global surge in employment in the clean-energy business as fossil-fuel companies faltered. Employment in the U.S. solar business grew 12 times faster than overall job creation, the International Renewable Energy

Can 3D printing solve problems of poverty and plastic waste in slums?

When Sidhant Pai visited a local rubbish dump in his home city of Pune, India, he was struck by the size and intensity of the operation. Large black crows swooping overhead, roaming pigs, overwhelming odours and groups of waste pickers collecting plastic bottles in large white sacks. There are an estimated 15 million people globally

The key to tackling climate change: electrify everything

Electricity is the only form of energy we really know how to decarbonize. Replace technologies that still run on combustion, like gasoline vehicles and natural gas heating and cooling, with alternatives that run on electricity, like electric vehicles and heat pumps. Get as much of our energy consumption as possible hooked up to the power grid.

Reducing Energy Poverty Not Only For Solar And Impact Investors

2.3 billion people are living around the world in energy poverty and lack access to reliable electricity or live off the grid completely. Of this population, over half spend about $27 billion annually on mobile phone charging and lighting with kerosene, candles, flashlights, or other fossil fuel-powered technologies.

Paper or plastic? U of T study finds how we pay for things may affect how we feel about them

When it feels easy to pay for something, it might just make us feel less connected to what we’re buying, a new U of T Scarborough study says. “Debit and credit cards rule the marketplace, and while going cashless is convenient, that convenience may come at a price,” says Avni Shah, an assistant professor of
