Hope Reducing Carbon Dioxide Emissions from Shipping by Half A ship-borne system employing accelerated weathering of limestone to capture carbon dioxide from exhaust gas is better and cheaper than land-based systems.
Climate Change Climate Change: Are You Less At Risk Than Other People? Most of us think others are more vulnerable to climate change than we are, regardless of objective reality.
Hope How Policy Is Like the Tide Policy might seem slow and boring, but sometimes it's the most effective action. Solar PV for parking lots is a good example.
Opinion Are Reading and Thinking Obsolete? Musings and evidence on the decline of higher-level reading and the art and practice of thinking well.
Measurement Efficiency - A Little Bit Goes a Long Way Like comedian Rodney Dangerfield, energy efficiency "don't get no respect," but it deserves more policy attention and more widespread application.
Hope Gyrotron Well Drilling for Deep Geothermal Energy Bit-less deep-well drilling teases the prospect of terawatts of clean energy.
Electricity No One Said It Would Be Easy An Australian mining company's first attempt to build an entirely gravity-powered ore train doesn't quite work (yet), but we shouldn't be discouraged.
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.
Energy 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.
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 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
Hope Reusable Hospital Isolation Gowns Radically reducing the biggest source of hospital waste for GHG and cost reductions
