Physics Professor: Hey U Guyz…This Electrical Field Boosts Engine Efficiency

| суббота, 3 октября 2009 г.

Electrorheology is a pretty complicated looking word. It doesn’t even look like it’s spelled correctly, although it is. I checked. It’s equally difficult to define, even after I looked it up online. But I’ll attempt: Electrorheology is a phenomenon whereby particles of a liquid become more or less viscous upon the application of an electric field of very low current.

A Temple University physics professor has developed a simple device which could improve automotive fuel efficiency by 20 percent using electrorheology. The device creates an electric field that thins fuel, so that smaller droplets are injected into the engine. That leads to more efficient and cleaner combustion.

Six months of road testing in a diesel-powered Mercedes-Benz showed the device improved mileage from 32 mpg to 38 mpg. The device can apparently be used with diesel, regular gasoline, kerosene, and even biodiesel.

If this kind of technology is used in the trucking industry, it could save tens of billions of dollars and have a major impact on the economy by lowering the costs to deliver goods and services.

New Jersey Bus Driver Suspended For Leaving 5-year-old Girl On Bus

| среда, 30 сентября 2009 г.

In Franklin Township, New Jersey [everyone is shocked, I know] a school bus driver has been fired after he failed to check the bus for stragglers before knocking off for the afternoon. According to NJ.com, the 5-year old girl had fallen asleep in the back of the bus and went unnoticed by the driver after his finished his route. Now here’s why this is slightly controversial: the man had been a reliable school bus driver for 19 years, and as soon as he realized the girl was on the bus, he drove her to her home immediately, completely unharmed. Still, the Franklin Township School Board saw “just cause” to relieve the driver of his duties, explaining that the driver had failed district policy requiring all bus drivers to make a thorough sweep for students before ending their run. “I certainly regret this incident even took place,” Superintendent Michael Kozak lamented. “Hopefully, this is an incident we will not have to deal with again.”

NJ to Philadelphia Bridge Toll Raised to 4 Dollars

|

This past Sunday, the Delaware River Port Authority raised the toll to cross all the major bridges connecting Philadelphia and NJ: The Walt Whitman, Ben Franklin, Betsy Ross and Commodore Barry. And in 2 short years, they plan on raising it to $5 dollars. This hits me pretty hard, since I use the Betsy Ross Bridge daily.

I’ve talked about this problem before, and the solution is obvious to me: Privatize the bridges.

The DRPA (Delaware River Port Authority) is over a billion dollars in debt, and they say they need the extra income to pay down that debt. One of the reasons stated for the increase is that less people are using the bridge, so they need more money. Stop and think about that for a second. What if this were a private business? If less people are using your product or service, do you raise the price?

The poor management of the DRPA caused the billion in debt, and now they’re passing it off to the good citizens of the Philadelphia and NJ area. If these bridges were built only a few years ago, we wouldn’t have these absurd tolls, there would be a scaled toll system, where higher tolls are paid during busy traffic hours and lower tolls are paid during off hours. That’s too complicated for a government run enterprise though.

The time is now, DRPA can still sell off these bridges piecemeal. They could sell one of the bridges to a private firm and use that revenue to pay down debt. It’d be a step in the right direction.

Call your local representatives people.

National Speed Limit Part II: Return of the Ridiculous Law

| понедельник, 7 сентября 2009 г.

In 1995, Ralph Nader said “history will never forgive Congress for this assault on the sanctity of human life.” Why? Because Congress had just repealed the 55 mile per hour speed limit. In the years following the repeal, 33 states raised their speed limits, and the average fatality rate actually fell in those states. Meanwhile, Americans have saved some 200 million manhours in terms of less time spent on the road. The net economic benefit of that being between $2 and $3 billion a year.

So what have we learned? Time is a resource more precious than any other, and Ralph Nader is a lunatic zombie with no understanding of real economics.

Or have we learned anything at all? George W is the new Nixon, Iraq is the new Vietnam, and very expensive oil is the new kinda expensive oil. And just like the 1970s, national speed limits are back on the American brain. To help out the problem of expensive gas, senator John Warner (R-VA) wants a national speed limit, and he’s not the only one. Jackie Speier (D-CA) earlier this month introduced a bill that would cap highway speed limits at 60 mph. It’s currently in bureaucratic limbo just outside the House Committee on Transportation.


An interesting side note, Senator John Warner was married to Elizabeth Taylor at one point.

In an interview with TIME, John Warner talked about the 55 mph limit and said he’s trying to help “the many millions and millions [of Americans] of limited means, sitting around their kitchen table trying to figure out how to make ends meet…Maybe some guy’s got a better idea, but I haven’t seen it.”

Well, Johnny, open your eyes:

In an earlier article, The National Speed Limit is a Tool for Nazi Thugs, I wrote about the air of fear that the national speed limit created, and how speed limits clearly don’t make us safer, and don’t help us economically. Here are the major points:

First of all, more than 80% of all drivers ignore speed limits, which creates this unintended consequence of universal police fear, where motorists are more afraid of their police than they are of getting into an accident. That’s not good for anyone. Secondly, they don’t help out the economy; the money wasted in lost time greatly outweighs any potential benefit. And thirdly, they’re not safe; they just don’t prevent accidents, and in fact, they make them worse. All the data out there is crystal clear on this fact.

Look at the German Autobahn, which has no speed limits at all in certain areas. Fatalities per mile of road there are almost 30% lower than they are on the US interstate. We need to learn. Politicians need to learn. Speed limits are not the answer.

But Jackie Speier and John Warner still think they are; in fact, John Warner thinks he’s helping people. In the TIME article, he said “I’m just sensitive to people’s pain. Who’s got the courage to do something like this?”

Courage? To say something completely contrary to the facts and get behind an outdated, dangerous law that will waste billions of dollars and have an actual negative impact on peoples lives…maybe kill people? I guess you have that kind of courage, Mr. Warner.

Disagree? Just see what happens when a bunch of students decide to obey the speed limit as a form of civil disobedience:

Olympic Air Quality Concerns Leads Bejing to Ban Auto Repairs and Painting

| четверг, 27 августа 2009 г.

It has been some time since China had any good press, and recent protests over air quality by Olympic athlete’s and international protests for a free Tibet have done little to lighten the mood. Things for China did not improve in the slightest when a University of California study released their findings and named China the #1 polluter on the planet (…YES! High Five!).

Finding it easier to squash and ignore the Tibet issue Chinese authorities are focused on showcasing their Olympic host city. As a means of addressing air quality issues Bejing has issued a few directives that are aimed at resulting in more sunny days in the Capital city.

In an effort to curb carbon emissions from automobile traffic Bejing has issued the equivalent of Drive-Day rationing. Based on the last letter of your license plate cars are ordered to only drive every-other day. And in a well-mannered society such as China we are certain there will not form a Black Market for extra license plates. (more…)
