The claim is that it is opposite of the Wankel engine. If you look at the video you'll see that the burn chamber is closed off by the rotor giving a well defined (small) space in which the burn occurs. --- End quote --- So put your money where your mouth is: buy some shares. --- End quote --- Why would I do that? It is just an interesting concept from a technical point of view. |

It's about as interesting as an over-unity machine. |

--- Quote from: nctnico on February 17, 2021, 09:32:28 am ---Yes it will. Politicians count ICE hybrids as electric cars as well. Car makers say they will switch to BEVs but they know very well that it just isn't affordable / financially interesting for everyone. --- End quote --- I don't think so. In the UK, for instance, they're talking about a cutoff date of 2030 for conventional vehicles and 2035 for hybrids. By 2050, gasoline-powered passenger cars will be as common as horses are today. Strictly an item for wealthy hobbyists and a very few specialists. It's crazy to put any money into R&D of gasoline-powered engines at this point. It's so pointless that it almost has to be a scam. If KPMG disagrees, well.... we'll see, I guess. |

LP has the advantage of great power density that's apparently even better than traditional NA rotarys however it's not clear if they have obtained an even reasonable operational lifetime from the LP design although if they are making that diesel version and with the compression ratios required for self combustion they need be reasonably strong. From the promotional blurb it seems they can upsize the single rotor design to 1000hp so the need for a multi rotor design like the Mazda rotarys is apparently unnecessary. Wonder if they respond well to turbocharging like the Mazdas ? |

There is a move towards the political right in Europe where the climate skeptics &deniers reside as well. In the end moving to new ways of transportation need to be affordable for the public and (unfortunately) the left parties fail misserably to show how to achieve that. Trump's 'Climexit' may not be the last one we see. In the end it is up to the voters. |
