I would just like to mention a story about the 4 minute mile. People used to think that a man could never run a 4 minute mile. It wasn't until 1 guy did it, that now over 1000 have done it. If we set our standard too low, we will never acheive greatness, go ahead... set the bar high and stop being afraid of the unkown, grab and claw at it until you get there. If the readers of this forum can't do it, no one can.
Just reread your post 50 Caliber - Since you incorporated my post in your response, I feel some responsibility and wanted to comment that regardless of personal political views, I think the post is a bit strong for this type of forum. I apologize if my response offends you, but I believe in respectfully expressing opinions, even though we may feel strongly about it.
J Williams: I apologize if you misunderstood my point, I was referring to another reader that did not seem to get the point that you mention. I also said to check you own local company, because everywhere IS different as you point out. There is no bias here. BTW: I am not a proponent of natural gas either, but that is what my company uses mainly for power, it is different elsewhere.
Mr. 50 Caliber it appears you have a stuttering problem but I would like to remind you that in 1981 the VW diesil Rabbit got 55 MPG. This is, if anyting, an anemic goal and we should be setting the standard far higher.
Ah yes, Romney is responsible for what you believe he will do, not what he says.
But Obama get's credit for what you believe he meant to do, not what he did.
BO's fiscal policy is not a change from Bush, it is Bush on heroin. Bush was hardly a fiscal conservative. Overspending was bad (as Senator Obama noted), spending like an insane man is hardly the cure.
BTW, the housing crisis, and by extention the recession, was the result of policies starting in the 70s and accelerated in the 90s.
The standard is a goal. A goal is a goal. It may be acheivable, it may not. If goals were set as "sure things", what is the point? The new standard is meant to push us. The truth is that if it is not acheivable, whoever is President at the time, (won't be Romney or Obama by then), will have to decide to revise the standard to a new standard as long as industry shows that it made a decent effort. I think the goal is plenty good enough, primarily because the comments I see posted show that many of us are unsure if this is possible.
On the real side, not political, we all know, standard Diesels like Volkswagen's TDI had been getting 50 to 60 MPG for a while. Then the crackdown on emissions took the smallest standard Diesel off the market in many states because of high emissions. The new genration of clean Diesels does not acheive 50 MPG due to emissions control losses in efficiency.
There is a great article in Mechanical Engineering magazine, September 2012 issue, called "The Gasoline Diesel".The article by Steve Ciatti of the Argonne National Laboratory's Transportation Technology Center discusses a new combination of engine technologies which uses low octane (80 to 85) gasoline called a Multizone Stratified Compression Ignition (MSCI) engine. This is actually a project which is partnered with Shell Oil. The benefits are great in both efficeincy gained and emissions reduced. This is done thru the method of Low Temperature Compression (LTC) But it doesn't stop there. Because the octance needed is so low, it can reduce the cost to refine oil to the lesser grade. And still better, the simplification in design of a compression ignition engine over a spark ignition engine can reduce engine cost as well.
I look at this technology and see a real possiblility that it can yield cars with MPG ratings above the 55 MPG range. Especially if we combine that with the electric power in a new generation of hybrids.
Don't worry, to cut teenagers calorie consumption by the year 2025. The Almighty Magical Mandate Magician has a plan. He will simply wave his crooked magic wand (the one bestowed upon his Excellency by a Kenyan voodoo priest in wet dream land) and utter a few twisted words from his special teleprompter and pooooooofffffffffffffffffff. Now teenagers only require 200 calories a day. What a crock! This genius needs to take a few physic classes.
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
