  1. For some of us, hybrid cars are not a reality yet and we have to consider the pros and cons of using a diesel engine versus a gasoline engine. Gasoline engines are less costly upfront but more costly to operate. Diesel engines get greater torque so if towing is an issue, as it for many of us during our work hours, diesel becomes more attractive. As far as greenhouse gas emissions go, a diesel engine puts out less per mile than does a gasoline engine, primarily because of its mileage superiority. Particulates are another matter however, and diesel engines expel far more of these than do gasoline engines. Even with advances in diesel technology that is not likely to change any time soon. With the advent of biodiesel, less dependence on fossil fuels is a policy advantage for diesel engines, but that is a somewhat different issue. In Europe almost 40% of new vehicles sold have diesel engines. The comparable figure for the US is far lower. I suspect that will change over time as the cost of fuel rises making diesel engines more economical for those who drive more miles per year. Some excellent reads can be found on this subject.

  3. The Great Fraud

    He also has only a passing relationship with the truth, ut then that is all old news. The apple didn't fall far from the tree. His father lied under oath regarding Iran-Contra, and no doubt lied many other times as well. It's SOP for politicians from both sides of the aisle.
  4. Spring in Winter!?

    We had daffodils here in January last year but not until February this year, and not in the same amount. Some trees flowered a week or so ago as well. February has been colder this year than last, but on the whole, warmer than in the past. Of course we don't get a snow cover here...
  5. I'm joining this debate/discussion late but let me offer an answer to the original question: "Why is climate change not in the USA primaries?". The simple answer is that it isn't politically expedient to do so. Many if not most of those who identify themselves as Republicans do not believe or doubt that there is an issue. Many would not vote for a candidate who will "raise taxes" to do something about it. Democratic candidates take the environmental vote more or less for granted, and they don't want to offend the undecideds or give Republicans an issue on which to attack.
  6. Electric Delivery Truck Recharges in Ten Minutes!

    I think that depends on how the electricity was generated. If it is generated in a dirty coal burning plant, as much of US electricity is, then it isn't necessarily cleaner in the long run. It may be cleaner in the city where the truck is running in the short term, but acid rain from the sulfur emissions have serious consequences. Add to that the fact that no process is 100% efficient (isn't that the second law of thermodynamics?) and you now are using two processes to power the vehicle, each with its built-in inefficiencies. Until electricity is effectively generated with clean, renewable energy sources, every time you turn on a light you are burning fossil fuels and creating greenhouse gases.
  7. Hello there

    I'm Jim. I live on the east coast of the US. I discovered this site in a search. I'm looking forward to becoming an active participant.
