Will future office buildings harvest algae in their lobbies?
In a prototype of an urban algae farm now on display in an exhibition in Kazakhstan, shows how algae could fit inside existing buildings where people live and work. Designers suspended coils of lightweight glass tubes from the ceiling, attached to pumps that visitors can press to send carbon Read More...
Sweden uses revolutionary cement technology to get to zero emissions
Sweden has committed to reaching net-zero emissions of greenhouse gases by 2045. Today, only 5 percent of the electricity Swedes consume comes from burning fossil fuels. Still, the country has big challenges to overcome to meet the ambitious goal. Here’s one innovative solution Sweden is Read More...
To curb climate change, we need to protect and expand US forests
Forests have been removing carbon dioxide from the atmosphere and storing carbon for more than 300 million years. When we cut down or burn trees and disturb forest soils, we release that stored carbon to the atmosphere. Since the start of the Industrial Revolution, one-third of all carbon dioxide Read More...
Cheap catalysts turn sunlight and carbon dioxide into fuel
Scientists have long dreamed of mimicking photosynthesis, by using the energy in sunlight to knit together hydrocarbon fuels from carbon dioxide and water. Now, a cheap new chemical catalyst has carried out part of that process with record efficiency, using electricity from a solar cell to split Read More...
Australia set to use hydrogen to export its solar power around the world
The future of hydrogen is bright. Since it doesn’t emit carbon dioxide when its burned, hydrogen is potentially the ultimate source of clean energy. And thanks to recent innovations, we now have the ability to produce hydrogen more efficiently, use it to store other clean energy, and even Read More...
Research explores 'artificial leaf' system for solar fuel production
If human beings could mimic the way plants make their own fuel, it's not a stretch to say that Earth's energy needs could be solved. The way leafs convert sunlight and carbon dioxide into life-sustaining chemical energy is a resourceful process, and scientists are attempting to do the same thing Read More...
Possibility: It’s their future
From The Intelligent Optimist Summer 2016 In what could be a growing movement, courts in the United States and the Netherlands are siding with environmental activists who argue that governments that promote fossil fuel use and development are violating environmental laws and constitutional rights, Read More...
Rock, paper, progress
From The Intelligent Optimist Magazine Summer 2016 A new “stone” paper devised in Taiwan uses calcium carbonate instead of wood pulp. It could save the forests, but is the world ready for the ultimate paper-vs.-plastic question? By Karin Klein The first thing I notice about my new notebook is Read More...
Nature's air filter
From The Intelligent Optimist Magazine Fall/Winter 2016 Air pollution is responsible for roughly 7 million deaths worldwide every year. Air-borne pollutants also cause heart disease, stroke, skin diseases, reduced fertility and miscarriage, and cancer. There’s a solution: Plants that clean the Read More...
