Engineers from MIT have developed an alternative system for generating electricity that harnesses heat and uses no metals or toxic materials. The batteries that power the devices of modern life, from smartphones and computers to electric cars, are mostly made of toxic materials such as lithium that can be difficult to dispose of and have limited […]

Engineers from Stanford have developed a state-by-state plan to convert U.S. to 100% clean, renewable energy by 2050.
In the dusty khaki scrubland of South Africa’s inhospitable Northern Cape province, brightly polished mirrors flash light across the landscape as they rotate slowly to follow the sun, producing electricity for 80,000 homes.
The hurricane season passed off relatively quietly last year. Category 2 hurricane Gonzalo hit Bermuda in October 2014, briefly making the world’s headlines, but it did relatively little damage, apart from uprooting trees and knocking out power temporarily to most of the island’s inhabitants.
Smog in Beijing Yi Cui of Stanford and his students have used a material commonly used in surgical gloves into a low-cost, highly efficient air filter that could be used to improve facemasks, window screens, and could even reduce the exhaust from power plants.
Researchers at the Global Challenges Foundation released earlier this month a thorough and unsettling look at what threatens human civilization.
Illustration of reflective panel on building A new ultrathin multilayered material can cool buildings without air conditioning by radiating warmth from inside the buildings into space while also reflecting sunlight to reduce incoming heat. Fan Lab Stanford engineers have invented a material designed to help cool buildings. The material reflects incoming sunlight, and it sends […]
Robin Speronis lives off the grid in Florida, completely independent of the city’s water and electric system. A few weeks ago, officials ruled her off-grid home illegal. Officials cited the International Property Maintenance Code, which mandates that homes be connected to an electricity grid and a running water source.
For many more people than realize it, electric cars are already adequate for their needs and better than a gasmobile for their bank account and quality of life. However, it often isn’t good enough for disruptive technology to be better than the incumbents. It has to be much better. The target for electric cars, in […]
This is an artist’s concept of excess left-hand aspartic acid created in asteroids and delivered to Earth via meteorite impacts. The line at the bottom is a chromatogram showing that left-hand aspartic acid (tall peak in the center, with diagram of left-hand aspartic acid molecule on top) was four times more abundant in the meteorite […]
