Comments Off on NASA considers puncturing Yellowstone supervolcano to save life on Earth

A new study from NASA’s Jet Propulsion unit has determined that the threat of a supervolcanic eruption to life on Earth may be more pressing than any interstellar collisions. An eruption of a supervolcano, like that found in Yellowstone National Park in the United States, could trigger a collapse of the global agricultural and economic systems and result in the deaths of potentially millions of people. Although NASA scientists can’t predict when such an event would occur, they have already begun preparing a preventative measure: drilling into the magma chamber of a supervolcano to cool it down. Although the potential consequences of a supervolcano eruption would be devastating, earthlings should rest easy knowing that the chance of such an eruption taking place this year is roughly 1-in-730,000. Even then, there is a chance that it could be nothing more than a little lava flow. Nonetheless, NASA scientists are preparing to deal with the problem before it happens. Related: World’s most active volcano harbors a tiny off-grid home—and you can stay overnight Magma eruptions occur only when it is thoroughly melted by intense heat; cooling magma down by 35 percent would prevent a supervolcano from erupting. To do this, the scientists envision using a drill to puncture above the chamber, where hydrothermal fluids are pushed to the surface. Adding water in this highly pressurized environment would be sufficient to cool the magma. To avoid fracturing the surrounding rock and potentially setting off an eruption, NASA scientists suggest drilling into the supervolcano from below. It is estimated that such a plan would cost around $3.5 billion, although governments would be encouraged to think of this as an investment : Excess heat could be captured and transformed into clean energy .

Comments Off on True North Detroit is an affordable live-work community made from prefab Quonset huts

A number of grassroots initiatives and organizations are revitalizing Detroit as a testing ground for urban innovation. Edwin Chan and his Los Angeles–based design practice EC3 recognized the potential of the city’s underutilized community spaces and recently completed True North Detroit , a half-acre live-work community made from lightweight prefabricated Quonset huts. This small complex of nine vaulted buildings offers affordable housing for Detroit’s growing creative population. Located in the Core City neighborhood, about two and a half miles northwest of downtown, the community breathes new life into an area that consists mostly of vacant lots. Related: America’s first urban ‘agrihood’ feeds 2,000 households for free “The majority of Detroit’s housing stock is either out of date or completely dilapidated,” Edwin Chan said. “Rather than being determined by ‘market demands,’ True North’s design is an inclusive and aspirational vision to create a new typology of affordable housing and to promote alternative, creative lifestyles in one of the world’s most iconic cities.” Related: These tiny houses help minimum wage workers become homeowners in Detroit The architects modified the original shape of the Quonset huts to create more elongated, higher spaces ideal for a variety of activities. The center island houses the kitchens, bathrooms, and utilities. This space is built from durable polycarbonate , while the rest of the structure has a more transparent envelope that allows natural light into the interior. Affordable materials and building methods were used in the construction of the apartments, which range from 475 to 1,600 square feet. + Edwin Chan + True North Detroit Via Archpaper

People are using recycled laptop batteries to power their homes

Why spend thousands of dollars on a Tesla Powerwall when you could build your own – for a fraction of the cost? This is a question many alternative energy enthusiasts have asked, and it is ultimately what has led hundreds of people to develop their own versions using recycled laptop batteries. Now that plans for DIY Powerwalls are being shared for free online, several people have created rigs capable of storing far more energy than the Tesla version. On Facebook , YouTube and in forums , people are learning how to safely create their own DIY versions that cost much less than a Tesla Powerwall. One of the most popular powerwall builders is Jehu Garcia . He told Vice, “It’s the future. It’s clean, simple, efficient and powerful.” Joe Williams , another DIY powerwall enthusiast, added ”The end result is being able to rely on something I not only built myself but understand the ins and outs of to power some or all of my electricity in my home. That is inspiring.” There are several DIY versions capable of storing more energy than Tesla’s Powerwall. On the French forum  Diypowerwalls.com , user Glubux said his powerwall can store 28 kWh of energy. “I run all the house with it, in fact I even bought an electric oven and induction cooking plate to use the extra energy during summer,” they said. Australian YouTuber Peter Matthews claims he has created a gigantic battery that can store 40 kWh of energy. Reportedly, it harvests power from over 40 solar panels on Matthews’ roof and stores nearly enough power for his home’s electricity needs. “The only things I don’t run are the big air conditioners and the water heating system,” he said. The alternative energy aficionado created DIYpowerwalls as well as the most popular powerwall Facebook group . Related: Mercedes takes on the Tesla Powerwall with a new battery for buildings Most of the powerwall hobbyists recommend using 18650 lithium-ion batteries for their projects. The batteries are usually encased in a colorful plastic and can be found inside electronics, such as laptops. If sourced online or from a computer store, the batteries will cost more than $5 a piece. If obtained second-hand, from old Dell, HP, Lenovo and LG laptops, it’s possible to save hundreds — if not thousands — of dollars on the project. Of course, one might meet challenges collecting the batteries , as tech companies frown upon their creative repurposing. A positive effect of the DIY powerwall trend is that it reduces waste . According to Carl E. Smith, the CEO and president of  Call2Recycle , approximately 95 percent of consumer batteries which are sold in the US are not recycled and are ultimately thrown away. ”Virtually all batteries can be recycled into valuable secondary products which is the biggest reason why they should not be landfilled and should be recycled instead,” he said. Though it can be time-consuming to source the used batteries, it’s a worthwhile investment according to DIY powerwall enthusiasts. And, if one carefully follows instructions when building their own version (such as those that follow), the risk of burning down one’s house is minimized. Ultimately, there is a risk associated with creating your own energy storage device, but the trend can’t be ignored as it grows in popularity.

Click here to view the embedded video. A new report has revealed the underground workings of the Yellowstone National Park volcanic system – and in the process unveiled new details of how one of the world’s largest volcanoes could catastrophically erupt on a scale never-before seen by humanity. According to the Washington Post , an eruption in Yellowstone would eject 1,000 times as much material as Mt. St. Helens did in 1980, creating a disaster of global scale. Needless to say, scientists have been busy studying the inner workings of Yosemite’s volcanic system and a new study from the University of Utah now shows a complete diagram of Yellowstone’s system that reveals some stunning details that show how massive the eruption could actually be.

Comments Off on How Cameroon’s exploding “killer lakes” claimed over 1,700 lives

In 1986, Cameroon’s Lake Nyos was the scene of an extraordinary and devastating natural disaster. The lake quite literally exploded, releasing 80 million cubic meters of carbon dioxide in just 20 seconds, which caused the suffocation deaths of 1,746 people and 3,500 livestock. The lake experienced what is known as a limnic eruption. Lake Nyos is not the only body of water in the region to carry properties that lead some to term them “killer lakes,” but scientists are working to ensure that this never happens again.
