Supply chains can be a complex logistical challenge. But they pose an even greater environmental challenge. And it’s that latter problem — global supply-chain sustainability — where UK startup Sourceful is fully focused, although it argues its approach can boost efficiency as well as shrink environmental impact. So it’s a win-win, per the pitch. Early […]
Laser-initiated fusion leads the way to safe, affordable clean energy
Fusion power plants will eventually replace most conventional power plants and related large-scale energy infrastructure that are still so dominant today. There will be no need for coal or gas.
The 4 things needed to reach Biden’s ambitious 2050 solar goal
A report on the future of solar energy from the Department of Energy paints a sunny picture, if you will, of the next three decades, at the end of which nearly half the country’s energy will be provided by the sun. But for that to happen, big pushes need to happen along four major lines: […]
Forerunner is software for NFIMBYs, or no flooding in my backyard
Mayors have the toughest job in the world, and leading a city is only getting harder. Even as populations swell in urban cores across the world, climate change is constraining the geographies where that growth can happen. Coastal communities that are popular with residents are also taking a gamble when it comes to rising sea […]
Heimdal pulls CO2 and cement-making materials out of seawater using renewable energy
One of the consequences of rising CO2 levels in our atmosphere is that levels also rise proportionately in the ocean, harming wildlife and changing ecosystems. Heimdal is a startup working to pull that CO2 back out at scale using renewable energy and producing carbon-negative industrial materials, including limestone for making concrete, in the process, and […]
On the future of walls, or The Wall
Space may be the endless frontier, but here on Earth, we define space in the modern sense as something enclosed. Walls, fences and barriers enclose space, define it and make it legible. In fact, the sense of limits is so strong these days with place that we often have to add qualifiers like “open space” […]
Air conditioning is one of the greatest inventions of the 20th Century. It’s also killing the 21st
When did indoor air become cold and clean? Air conditioning is one of those inventions that have become so ubiquitous, that many in the developed world don’t even realize that less than a century ago, it didn’t exist. Indeed, it wasn’t so long ago that the air inside our buildings and the air outside of […]
How national security is being redefined by climate change
One of the most unfortunate fault lines in climate change politics today is the lack of cooperation between environmentalists and the national security community. Left-wing climate activists don’t exactly hang out with more right-leaning military strategists, the former often seeing the latter as destructive anti-ecological marauders, while the latter often assume the former are unrealistic […]
Is the best way to solve climate change to “do nothing?”
When it comes to climate change, it might seem that a book entitled “How to Do Nothing” would not only be irrelevant, but also downright obscene and even dangerous. Not to mention that after more than a year of pandemic living, many people are understandably fatigued at the prospect of continuing to keep their lives […]
Bill Gates offers direction, not solutions
Bill Gates has solved many problems in his (professional) life, and in recent decades, he’s been dedicated to the plight of the world’s poor and particularly their health. Through his foundation work and charitable giving, he’s roamed the world solving problems from malaria and neglected tropical diseases to maternal health, always with an eye toward […]
