“The clothing industry is said to be the world’s second most polluting business, runner-up in grubbiness to oil.”
Off-grid housing that actually works for families is hard to come by, but that’s what ReGen Villages is striving towards with their concept for new self-sustaining communities.
The startup real estate company has a dream to create regenerative communities that not only produce their own food but also generate their own power, meaning what’s usually only possible for rural areas with renewable energy sources would be a reality for people that want these luxuries while having close neighbors.
This idea is more than just a dream, however, as the development company has its sights on their first site in Almere, Netherlands with the goal of opening it in 2018.
The year is 2030. Former president Donald Trump’s border wall, once considered a political inevitability, was never built. Instead, its billions of dollars of funding were poured into something the world had never seen: a strip of shared territory spanning the border between the United States and Mexico. Otra Nation, as the state is called, is a high-tech ecotopia, powered by vast solar farms and connected with a hyperloop transportation system. Biometric checks identify citizens and visitors, and relaxed trade rules have turned Otra Nation into a booming economic hub. Environmental conservation policies have maximized potable water and ameliorated a new Dust Bowl to the north. This is the future envisioned by the Made Collective, a group of architects, urban planners, and others who are proposing what they call a “shared co-nation” as a new kind of state.
Many people have imagined their own alternatives to Trump’s planned border wall, from the plausible — like a bi-national irrigation initiative — to the absurd — like an “inflatoborder” made of plastic bubbles. Made’s members insist that they’re serious about Otra Nation, though, and that they’ve got the skills to make it work. That’s almost certainly not true — but it’s also beside the point. At a time when policy proposals should be taken “seriously but not literally,” and facts are up for grabs, Otra Nation turns the slippery Trump playbook around to offer a counter-fantasy. In the words of collective member Marina Muñoz, “We can really make the complete American continent great again.”
Sometimes people bring up overpopulation scenarios where the population can fit inside Texas. But they ask, what about all the stuff that supports that population? Here is one answer.
Located in an abandoned 70,000-square-foot factory in Newark, New Jersey, the world’s largest vertical farm aims to produce 2,000,000 pounds of food per year. This AeroFarms operation is also set up to use 95% less water than open fields, with yields 75 times higher per square foot. Their stacked, high-efficiency aeroponics system needs no sunlight, soil or pesticides. The farm’s proximity to New York City means lower transportation costs and fresher goods to a local market. It also means new jobs for a former industrial district.

Depression, anxiety, grief, despair, stress—even suicide: The damage of unfolding climate change isn’t only counted in water shortages and wildfires, it’s likely eroding mental health on a mass scale, too, reports the American Psychological Association, the preeminent organization of American mental health professionals.
Direct, acute experience with a changing climate—the trauma of losing a home or a loved one to a flood or hurricane, for example—can bring mental health consequences that are sudden and severe. After Hurricane Katrina, for example, suicide and suicidal ideation among residents of areas affected by the disaster more than doubled according to a paper led by Harvard Medical School, while one in six met the criteria for PTSD, according to a Columbia University-led paper. Elevated PTSD levels have also been found among people who live through wildfires and extreme storms, sometimes lasting several years.
But slower disasters like the “unrelenting day-by-day despair” of a prolonged drought, or more insidious changes like food shortages, rising sea levels, and the gradual loss of natural environments, will “cause some of the most resounding chronic psychological consequences,” the APA writes in its 69-page review of existing scientific literature, co-authored by Climate for Health and EcoAmerica, both environmental organizations. “Gradual, long-term changes in climate can also surface a number of different emotions, including fear, anger, feelings of powerlessness, or exhaustion.”

The team tested their device on a prosthetic hand. When the skin patches on the skin were enabled, the prosthetic could touch and grab soft objects like a normal hand. But when the skin was not turned on, the hand crushed the objects.
The skin requires just 20 nanowatts of power per square centimeter, according to the paper. Right now, the energy captured by the photovoltaic cells has to be used immediately, but the team has another prototype in development that includes flexible supercapacitors to store excess energy.

Back in August 2014, researchers at Michigan State University created a fully transparent solar concentrator, which could turn any window or sheet of glass (like your smartphone’s screen) into a photovoltaic solar cell. Unlike other “transparent” solar cells that we’ve reported on in the past, this one really is transparent, as you can see in the photos throughout this story. According to Richard Lunt, who led the research at the time, the team was confident the transparent solar panels can be efficiently deployed in a wide range of settings, from “tall buildings with lots of windows or any kind of mobile device that demands high aesthetic quality like a phone or e-reader.”
Now Ubiquitous Energy, an MIT startup we first reported on in 2013, is getting closer to bringing its transparent solar panels to market. Lunt cofounded the company and remains assistant professor of chemical engineering and materials science at Michigan State University. Essentially, what they’re doing is instead of shrinking the components, they’re changing the way the cell absorbs light. The cell selectively harvests the part of the solar spectrum we can’t see with our eye, while letting regular visible light pass through.
Scientifically, a transparent solar panel is something of an oxymoron. Solar cells, specifically the photovoltaic kind, make energy by absorbing photons (sunlight) and converting them into electrons (electricity). If a material is transparent, however, by definition it means that all of the light passes through the medium to strike the back of your eye. This is why previous transparent solar cells have actually only been partially transparent — and, to add insult to injury, they usually they cast a colorful shadow too.
LIMA, Peru (AP) — If human beings finally reach Mars, they may find themselves depending on the humble, if hardy potato.
Scientists in Peru have used a simulator that mimics the harsh conditions on the Red Planet to successfully grow a small potato plant.
It’s an experiment straight out of the 2015 Hollywood movie “The Martian” that scientists say may also benefit arid regions already feeling the impact of climate change.
