Hybrid and Electric vehicles explained

"...This is because in hybrid and electric vehicles, unlike gas-powered cars, only part of — or none of — the propelling force is generated by engines. They use electric machines, featuring a high-efficiency energy conversion process at around 90 per cent to propel the vehicle. Electric machines improve fuel economy and drivability..."

UBCO researcher studying solar energy conversion tech

"...“Part of the challenge with this type of research is the way different solar energy conversion technologies work, each is completely distinct,” explained Dr. Godin. “It’s not obvious how, or even if, you can compare photovoltaics, which generate electricity, to photocatalysts, which generate high energy chemical fuels such as hydrogen..."

"Tiny skyscraper" electrodes boost bioenergy output of blue-green algae

"...Scientists have long studied the abilities of photosynthetic bacteria that turn sunlight, carbon dioxide and water into energy, and by giving these communities a home likened to a high-rise apartment block, a team has broken new ground in this space. These tiny grids of "nano-housing" create the optimal environment to not just foster the rapid growth of these bacteria, but take their energy-harvesting potential to new heights. Also known as cyanobacteria or perhaps more familiarly, blue-green algae, photosynthetic bacteria can be found in all types of water, where they use sunlight to make their own food..."

First float of grid-connected wave energy system installed in Jaffa Port

"..."The installation of the first floater is a significant progress toward the first grid-connected wave energy array installation in Israel," said EWP CEO, Inna Braverman. "Preparation for the installation of all remaining floaters on the external side of the Jaffa Port breakwater is in advanced stages and we are relishing over the prospect of being operative soon in the Mediterranean waves. "Once in place, the array and energy conversion setup will undergo thorough functionality and capacity testing ahead of official connection to the local power grid..."

Squirrel-cheeked liquid H2 airliner will take you anywhere in two hops

"...The team also projects that these machines will "have superior operating economics than conventional aircraft from the mid-2030s onwards," as hydrogen prices fall. There's still some technological and logistic mountains to climb, though. "The challenges of realizing liquid hydrogen," reads FlyZero's energy source comparison and selection report, "include, but are not limited to; the storage and distribution of a cryogenic fuel onboard an aircraft, developing sustainable technologies for stable and reliable hydrogen combustion in gas turbines, efficient energy conversion and thermal management of hydrogen fuel cells and hybrids thereof, minimizing the generation of other climate impacts i..."
