Hope Sail-Powered Cargo Ships Scale Up A new, much-bigger addition to the world's fleet of hybrid sail/diesel-powered commercial cargo ships.
Geothermal vs Ground-Source Energy: What’s the Difference? Lots of naturally-occurring (low-carbon) heat is underground. Using it to generate electricity and provide heat for our buildings and processes is becoming more common.
Extinction The Long Way Home When a beloved species moves back from near-extinction, we feel joy. But this is the Anthropocene, when many more species are threatened than are saved every year. Part 1 in a series on extinction.
Carbon Ecosystem Engineering: How Animals Positively Shape Their Environments Animal ecosystem engineers modulate the availability of resources to themselves and other species by improving ecosystem structure and function, in the process consistently sequestering and storing more carbon.
Hope EVs Deliver Lowest Lifecycle Carbon Footprint Everywhere Cradle-to-grave GHG emissions of light duty electric vehicles are lower than all forms of their internal combustion-engined equivalents, no matter the region
Materials Cooler Cement Changing the surface microstructure of cement reduces concrete's contribution to global warming by keeping structures cooler
Hope One New Way of Making Low-carbon Cement Even cement production can be electrified, for a 90% reduction in GHGs
Hope Climate for the win! The Vermont Greens FC won their 2025 national championship. Why it matters for climate change.
Science Sentinel 5 ... Away! The new spectroscopic instrument Sentinel-5A launched on August 12, 2025. It's ready to help us understand what's going on in our atmosphere.
Electricity Kilowatt Batteries. OMG! Sophisticated and useful energy-dense "personal power stations" have quietly come to market. They are impressive.
Hope Teach your children well If we have hope, it will be realized from the impact of coming generations.
Science Science Is Not Enough The gap between peer-reviewed certainty and public indifference creates problems.
Hope Tidal Turbine Bearings and Seals Critical components for successful long-term tidal turbine operation reach a major reliability milestone.
Wind Bladeless Wind Generators A Spanish company is developing wind generators that exploit the vortex-shedding effect. The tapered towers have no rotating parts.
Historical Perspective Oil Shocks and Microchips How buildings learned to stop wasting and start thinking
water More Fish in the Sea Marine preservation areas work well when properly managed. That's great ... because we need them.
Hope Reusable Hospital Isolation Gowns Radically reducing the biggest source of hospital waste for GHG and cost reductions
Media Modelling Media Misbehaviour: A First Step A new paper helps us understand why media behave so badly so much of the time.
