I’m currently working on another project, which is taking up much of my time. This week we had about 200mm of rain in one day. That could have been why my cable connection to the internet disappeared for 36 hours. I’m grateful to John D who sent me the links for each item in the following except the last.
Zero-emissions engine that runs on liquid air
A new zero-emissions engine capable of competing commercially with hydrogen fuel cells and battery electric systems appeared on the radar when respected British engineering consultancy Ricardo validated Dearman engine technology and its commercial potential.
The Dearman engine operates by injecting cryogenic (liquid) air into ambient heat inside the engine to produce high pressure gas that drives the engine – the exhaust emits cold air. It’s cheaper to build than battery electric or fuel cell technology, with excellent energy density, fast refuelling and no range anxiety. It just might be a third alternative.
Among the advantages are that it doesn’t catch fire or explode and doesn’t require rare materials. Continue reading Climate clippings 64
