Natural gas is one of the cleanest vehicle fueling options we have in the U.S. today, and 97% of what we use is domestically produced. Its use as a vehicle fuel reduces greenhouse gas and localized pollutant (like nitrogen oxides and volatile organic compounds which form ozone at ground level, and particulate matter) emissions. On top of that, it can be one of the least expensive vehicle fuels on an energy equivalent basis.

This toolkit was built with one purpose in mind: help fleets perform a first-cut cost analysis of transitioning part of their fleet to using compressed natural gas, or CNG. The toolkit was developed as an outgrowth to CNG bus conversions that the Virginia Clean Cities was developing; the project was funded by DOE.

The key pieces of the toolkit are:
an Excel spreadsheet (“The Calculator”) that shows you where and how to fill it out and calculates simple payback based on vehicle incremental cost and fuel cost savings;
a resources page that shows where to find all the numbers you will need to complete the spreadsheet; and
connections to Clean Cities coalitions and coordinators that can help you if you need help.

What this Toolkit does and does not do!
Does do: Allows you to find and utilize two primary numbers, the fuel price difference and your vehicle cost difference, to calculate a simple payback period. Perhaps more importantly, it helps you get basic pieces of information in one place to prepare for potential funding opportunities in the future.
Does not do: It does not include space for calculating cost differences like maintenance; changes needed to a fleet maintenance, refueling or storage facility; or the refueling infrastructure itself, which can be quite expensive.
What you need to know is that this is just a starting point for looking at natural gas for your fleet. Clean Cities coalitions, NGVAmerica, and other resources are out there to help you find the other numbers you need, so use the resources page to find those as you need them.

What do I do?
Simply go to the “calculator” page and all you need is provided there. An overview of what you will do in the spreadsheet is there, as is a list of the outside information you will need to get payback numbers for your chosen vehicles.


The listening experience goes beyond and expensive radio or iPhone. All too many people buy a nice stereo but neglect their wiring and speaker options. Unfortunately the expensive stereo, although important, is only part of the equation when it comes to a quality listening experience.

Speaker Location

Many different options exist when it comes to speakers. Much of the decision on type of speakers to buy will be dependent on the location of the speakers. Will these speakers be indoor or outdoor, wired or wireless, mounted or freestanding? The first option to consider is where the speakers will be located as well as where the power source will be located.

Although this seems like an obvious factor to consider, many people will buy indoor speakers to be used for outdoors. The problem is indoor speakers will soon rot out when they are exposed to the harsh outdoor elements. Also, cheap outdoor speakers will lack the strong sound quality that most people are looking for around their pool or deck. The best outdoor speakers are going to cost a bit more, but in the long run will outlast many  replacements of cheaper speakers, and of course, sound much better.

Wired vs. Wireless

Next to consider is the feasibility of wiring. Wireless speakers have come a long way and are sounding better and better, but the reality is they still are not nearly as powerful or crisp as their wired counterparts. Also, with wired speakers, the power source is of even more of a concern. Because wireless reception will need to pass to the speakers, being disrupted as least as possible is paramount to increase the likelihood of quality sound. When wiring is just not an option the wireless speakers are you’re only option. However, if you can wire your speakers, then you’re likely to receive a better quality sound considering you bought a decent pair of speakers.

The Wires Themselves 

Now that you have decided that you can wire your quality stereo and set of speakers, the rest seems straightforward. Well, that is what most people think. Surprisingly a lot of problems with wired speakers not performing up to their standards have to do with the wiring used. Again, this is a seemingly obvious point to make, but if the wire is not strong enough to handle the wattage that you plan to pump to your speakers; the wire will distort sound, or worse yet, melt and you’ll have no sound at all.

Mounted vs. Freestanding

It could just be a matter of opinion but mounted speakers almost always look better than do freestanding speakers. The freestanding speakers will always have a wire hanging out somewhere which detracts from the aesthetics they sought to capture in the first place. Therefore, carefully thought-out mounted speakers almost always look better than do freestanding speakers. Not to mention, those that are concerned with their quality of sound are usually also appreciative of a creative mounting job.

The factors to consider when attempting to achieve quality sounds aren’t extensive, however the aforementioned all too often get overlooked.  Be sure to consider the location, wiring availability and mounting location when trying to achieve that perfect look and sound.


At some point you have likely have researched on how to make a website and have seen some content talking about WordPress. What is the difference between website and WordPress anyway? Although they work similarly, WordPress is software bounded with scripts, which offers wide array of sophisticated yet super user-friendly features. Likewise it carries online visibility unlike a regular website which is only specific to containing files which can be accessed via IP addresses.

At an average, anyone can get a website at around $60; a portion of this for the domain name and the other for the software supplied by the Web Host. A little knowledge will definitely go a long way so if you want a free wordpress tutorial which is completely free try visiting which details everything you need to get starting creating a website. When everything is set, you would like to test your web page if it appears to the major browsers like Internet Explorer, Mozilla Firefox, Google Chrome, Opera and Safari. You should research on how to test your website in multiple versions of web browsers to make sure it provides a good user experience for all types of visitors.

As these browsers improve from time to time, you need to look into some factors to ensure that your web pages work well with these updated versions. One way is to validate the code of your site. Check for syntax error on HTML and CSS. A requisite knowledge on both may be required to troubleshoot more complex issues on web page errors. See to it that you have submitted your website to search engines. After all, creating a website and WordPress installation is all about online presence.

Many of us are curious about inversion therapy and how it can help us with our health especially the benefit it can give to our body. What is inversion therapy? Inversion therapy involves hanging upside down with the intention of therapeutic benefit. Inverting is the process of doing this kind of therapy. It can be done through hand balancing or via hanging. Hanging from a bar with the hands at the side is also a form of inversion. The gravitational pull may decompress the joints of the body below the anchor. Hanging with feet, as with gravity boots or using inversion table may cause each joint in the body to be loaded in an equal or in opposite manner to standing in an identical position of joint alignment. This kind of inversion therapy is often introduced as a relief for back pain.

During an occurrence of acid reflux, small amount of acid in the stomach escape from the stomach‘s doorway going to esophagus.  But then, gravity keeps much of the acid in the stomach away from its doorway.  However, gravity cannot its job on an inverted position. Combination of inversion table and acid reflux can be nauseating, very dangerous, and painful.

Is it true that inversion therapy is one way of relieving back pains? And how safe it is? Well inversion therapy doesn’t provide a long lasting relief for back pains. It involves hanging oneself upside down and the inverted position is not safe for those people suffering from hypertension, glaucoma and heart disease. When you remain inverted for a couple of minutes, your blood pressure increases and your heart beat slows. Also the pressure in your eyeball jumps dramatically. So if you have the above mentioned condition, try not to do inversion therapy to avoid any complications. Even pregnant women are in higher risk for the dangers related to inversion therapy. Make sure to look at inversion table reviews to determine which one is best for you. It is necessary to seek a medical professional’s advice regarding this matter if one is planning to do it. By doing it so, make sure that there is someone standing beside you whenever you need help in getting out from the apparatus or whenever  problems may occur regarding your physical condition. Inversion therapy takes gravitational pressure off the nerve roots and disk in your spine and increasing the space between the vertebrae. In attempting to relieve the pain, inversion therapy is one of many examples where spinal traction is being done. Detailed research shows that spinal traction is not effective for a long term relief. Moreover, some people find traction temporarily helpful as a part of more comprehensive treatment program for lower back pain due to spinal disk compression.
