Peter Cobbold Posted April 17, 2021 Report Share Posted April 17, 2021 This auto technology got a mention on BBCWales and is closer to home for me: https://www.riversimple.com/technology-behind-rasa-hydrogen-car/ Unfortunately hydrogen pumps are non-existent, and that tank in the rear looks vulnerable. In our hilly terrain the regenerative braking will help range. Peter Quote Link to post Share on other sites

Not unless the Law of Conservation of Energy has changed, as what you gain going downhill will be more than lost when you have to go uphill again! Pete Quote Link to post Share on other sites

Pete. But the loss of potential energy resulting from going downhill wiill be partly conserved in the capacitor and available to provide kinetic energy to start up the next . No need to fly downhill and take a run up the next. As long as the electrickery works, but those motor-in-wheel look vulnerable to water, mud etc. Peter Quote Link to post Share on other sites
stillp Posted April 17, 2021 Report Share Posted April 17, 2021 Yes, it will Peter, but the range will inevitably be less in hilly terrain than on the flat. Pete Quote Link to post Share on other sites
Peter Cobbold Posted April 17, 2021 Report Share Posted April 17, 2021 Pete, In Wales its downhill all the way ! Peter Quote Link to post Share on other sites

They would freeze up and stop the boiler from working. Roger Hi Roger, this condenser boilers are part of my job and I had never any issue with freezing exhaust fumes. But we have more frost here at Germany and the regulations do not allow to guide the fumes through walls - and let them end there (if this was the case). Indeed the highly wet fumes freeze on the wall, causes damages and alga. Ciao, Marco Quote Link to post Share on other sites

The pipes were not insulated a few years ago. Roger Quote Link to post Share on other sites
