Comments Off on Worlds newest mega-skyscraper opens in Seoul

The world’s newest super-tall building has opened in Seoul , Korea. Clocking in at fifth tallest in the world, the Lotte World Tower is a 554.5-meter (1,819 feet) tall skyscraper that knocks the 1WTC, the tallest U.S. building, out of the top five. Designed by Kohn Pederson Fox Associates , the solar-powered building will seek a LEED Gold accreditation and boasts additional record-breaking features including the world’s highest glass-bottomed observation deck, fastest elevator, and the highest swimming pool in a building. Set on the banks of the River Han in southern Seoul, the Lotte World Tower is a multibillion-dollar mixed-use tower that houses retail, offices, luxury residences, and a seven-star hotel. The sleek and tapered form of the 123-story building draws inspiration from the curves of Korean artistry and contrasts with Seoul’s craggy mountainous landscape. The building shape and interior combine a modern aesthetic with elements inspired by the Korean arts of ceramics, porcelain, and calligraphy.

The glass-floor observation deck on the 118th floor allows visitors to experience a busy Seoul intersection from a bird’s eye view. The skyscraper also includes a massive 2,000-seat concert hall, aquarium, movie theater, and food hall. Designed for the LEED Gold , Lotte World Tower is equipped with solar panels, wind turbines, external shading devices, and water harvesting systems. + Kohn Pederson Fox Associates Via Bloomberg Images via Kohn Pederson Fox Associates

New graphene sieve can remove even small salts from seawater

Comments Off on New graphene sieve can remove even small salts from seawater

Graphene is the world’s strongest material, but that’s not all it can do. The wonder material can also be used as a filter that removes salts from seawater so it’s safe to drink. While scientists have eyed graphene-oxide membranes for better filtration – and even showed graphene could filter out large salts – now 13 University of Manchester scientists developed graphene membranes that can sieve common, smaller salts out of water. It takes small sieves to remove common salts from substances like seawater, and in the past when placed in water graphene-oxide membranes swelled, and weren’t able to catch those smaller salts. The University of Manchester scientists found a way to control the pore size of the graphene to sieve those common small salts out of water. Professor Rahul Nair, one of the scientists part of the research, said the realization of “membranes with uniform pore size down to atomic scale” is a significant step. Related: Affordable new biofoam could revolutionize how developing countries clean water The discovery could open doors to efficient, less expensive desalination technology – which the university points out is crucial as climate change depletes water supply in modern cities. In just around eight years, 14 percent of the world’s population could face water scarcity, according to United Nations estimates, and not all countries can afford large, expensive desalination plants to provide relief to their citizens. The university says the graphene technology pursued by the scientists could revolutionize water filtration around the world, offering an affordable option for developing countries . The researchers think their discovery could be scaled up for wider use. Nair said in a statement, “This is the first clear-cut experiment in this regime. We also demonstrate that there are realistic possibilities to scale up the described approach and mass produce graphene-based membranes with required sieve sizes.” The journal Nature Nanotechnology published the research online yesterday.

Comments Off on How to view sustainability’s historic moment

Effectively addressing the barriers to creating the world so many wish to see is a tall order. In that effort, we shouldn’t expect complete change overnight.Change is often incremental. Awareness is often incremental. It comes in waves, as people get inspired by an idea, and they become the role models that inspire other people. Increasing waves of action correspond to increasing waves of awareness, as those that resonate with an idea reflect the idea back out to compete in the battle of ideas and earn increasing amounts of mental bandwidth.
