... The rest is waste heat. Wow! That's a lot better than all too many electricity power stations!... All on our only one planet, Martin See new freedom: Mageia Linux Take a look for yourself: Linux Format The Future is what We all make IT (GPLv3) |

... The rest is waste heat. Which is what started this thread, that electric cars are not green because power stations are not green. |

What is an F1 Power unit. Formula one ? Power plants can be quite efficient when the waste heat can be used in a steam district for heating or air conditioning or in a combined cycle, co-generation situation when the heat rejection can be assigned elsewhere. The electricity generated is almost BTU per BTU. At the University of Illinois' Abbot Power Plant we often hit 300 percent efficiency for our steam absorption air conditioning for our 170 buildings (most of the BTU's coming from the atmosphere) |

... The rest is waste heat. Which is precisely why we need to get away from dirty old inefficient polluting coal, and then similarly move off all the other old fossils to instead go clean and finally totally get away from all the pollution waste... We have the technology now. The main hurdle is overcoming the fossils monopoly to move over investment faster to zero pollution...

What is an F1 Power unit. Formula one ? Yes, F1 is Formula One. For an explanation of F1 Power Unit there is this from Honda, or a 2014 one from Renault |

Which is precisely why we need to get away from dirty old inefficient polluting coal, and then similarly move off all the other old fossils to instead go clean and finally totally get away from all the pollution waste... If we only did, but all the calculations showing we do assume that all the materials in the tech are made from zero CO2 electric, which doesn't yet exist. So as those items are deployed they actually accelerate global warming. Eventually the reality that nuclear is the only option, which is already ruled out, will sink in. While hydro is nice, just ask the salmon that can't spawn anymore. Or perhaps those extremely toxic rare earths used in wind farms that come from pit mines in China fueled by oil. Or those solar cells that only in the last year have been able to generate as much power in their lifetime as is used in their construction. Some day you will have to come to the truth that the solution is to reduce people to reduce consumption. |

How "green" is the making of the batteries? Bob DeWoody My motto: Never do today what you can put off until tomorrow as it may not be required. This no longer applies in light of current events. |

How "green" is the making of the batteries? Better define "green" Just CO2 or total environmental factors considering regulation or lack where they are made? |

How many Gallons of fuel does a petrol engine USE .. How much CO2 does it make ? And comparing a Race with normal family motor and how long and Gallons of fuel it would use in it's lifetime compared with a Race is well dubious Compare the lifespan of the Family Motor to .. Batteries ? ... allowing for new break throughs in Battery Tech Electric Cars are looking much better now . |

How "green" is the making of the batteries? Not a clue. I only posted the link because others where interested in alternative fuels. I personally don't like batteries, but admit they are essential and at the moment and probably the best solution, at the moment, for storing temporary energy in energy recovery systems. But would like to see more development on flywheels, but think they might not make it because of the weight of the flywheel itself and the enclosure it is in. My vote at this moment in time would be for a F1 style power unit built for longevity and economy fueled by LPG. |

How "green" is the making of the batteries? Oh yes, 13+:1 compression ratio engines + electric boost from harvested braking and heat sources, why not? If only I could get that on in a Japanese sports/touring motorcycle frame. :-D Cheers. |

I cannot find it right now, but I believe there was an article on an enhanced version of possibly the Stirling cycle motor that was purported to be able to cross the USA on 28 gallons of gas? It was, of course used to generate electricity to power the actual motors that moved the car. Still looking for it. "Freedom is just Chaos, with better lighting." Alan Dean Foster |

If you travel slow enough you don't have wind resistance and with the right tires you can cut road friction a lot, but it isn't a trip on the interstate with air conditioning! Also they may have calculated it for flat ground and not going over the Rocky Mountains. Some of those solar cars can do amazing feats, but they aren't a comfortable ride. Oh they can do it on zero gasoline. I sure wouldn't want to take one out in Manhattan traffic! |

Kittyman I just did some calculations and there seems to already be Bikes that can give approx. 80 miles per gallon and you would need that amount or slightly more to cross the States on 28 gallons Check this link out as it compares fuel consumption and you can look back to the 1930's all the way up to 2017(spose there the ones being released next year) http://www.totalmotorcycle.com/MotorcycleFuelEconomyGuide/ Just click on the year and a new page will show the mileage in MILES not Klm |

Kittyman I just did some calculations and there seems to already be Bikes that can give approx. 80 miles per gallon and you would need that amount or slightly more to cross the States on 28 gallons Seattle WA to Miami FL about 3300 miles @ 80 MPG = 41.25 Gal So 50% more is "slightly more" Got your thinking. |

Seattle WA to Miami FL about 3300 miles @ 80 MPG = 41.25 Gal Well no your wrong there I did assume from east coast to west was about 2500 not 3,000 and approx. 80-95 would do appox 2660 so just a miscalculation on how wide the country is 110 = 3080 miles so I wasn't that far wrong So cut the aggression please not warranted or called for I was agreeing with the kittyman and trying to post something that may help him in what he was looking for . |
