As we experience temperature extremes more often as a result of climate change, it predictably leads to an uptick in the use of air conditioning systems. This of course results in higher energy use, which, if it’s not coming from renewable sources, mea… Continue reading Spaceship tech slashes energy usage of existing AC systems by 50%
Water can hold a huge amount of thermal energy, and a new system to tap into this resource is being trialed in Scotland. A startup called SeaWarm uses heat stored in bodies of water for buildings, pulling four times more heat out than electricity used…. Continue reading HotTwist water-based thermal system cuts heating bills by 75%
Where there’s relative movement, there’s a chance to generate electricity, and vehicle wheels move up and down on their suspension the entire time they’re in motion. We first encountered regenerative suspension 15 years ago – so how’s it going?Continue… Continue reading Regenerative suspension… What happened to that?
Earlier this month, we featured a Whale Design propeller that looked to nature for improved efficiency. Switzerland’s ABB Marine has also been inspired by “the dynamic motions of a whale’s tail” for its multi-blade Dynafin propulsion concept.Continue R… Continue reading ABB’s cycloidal marine propellers: Efficient thrust in any direction

An age of greener, more efficient shipping may be in the offing as a specially modified 43,000-tonne bulk freighter completes a six-month sea trial using a combination of diesel engines and a set of high-tech automatic sails to catch the wind.Continue … Continue reading Winged cargo ship saves three tonnes of fuel per day on first voyage
A new industrial-scale ‘sand battery’ has been announced for Finland, which packs 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be about 10 times bigger than a pilot plant … Continue reading Giant ‘sand battery’ holds a week’s heat for a whole town
MVRDV loves to draw inspiration from the natural landscape, resulting in geological designs like the Valley and the Canyon. Now the Dutch firm riffs on nature once again with an impressively energy-efficient university building in Toronto that will be … Continue reading Energy-efficient university hub arranged around light-filled “fissure”
Sage Geosystems has pioneered a new form of cheap energy storage that uses the Earth as a giant bellows, pumping water into underground fractures, then letting it squirt back up at 70% efficiency – or 200% efficiency if you also harvest heat energy.Con… Continue reading Huff ‘n’ puff geothermal fracking: Earth batteries at 200% efficiency
Nobody wants to live in a drafty house, yet checking for substantial air leaks within a home can be a complex process. Scientists have now devised what could be a much easier method of doing so, utilizing a technique that dates back to 1864.Continue Re… Continue reading New spin on 159-year-old tech could easily visualize air leaks in homes
