Top Five of the Most Fuel Efficient Cars

With oil prices steadily climbing up, it seems logical to start considering fuel economy among the many criteria that consumers use for buying their next vehicle. Wise consumers are now eyeing at the most fuel efficient cars that the US Environmental Protection Agency (EPA) comes up with every year. This list pertains to cars that are capable of attaining the best gas mileage due to their specific features and engine performance.

Here is a list of the five most fuel efficient cars that are available in the market today.

Honda Civic GX

One of the main reasons why this particular Honda model has made it to the list of most fuel efficient cars is that it uses compressed natural gas unlike other vehicles. It has a fuel economy rating of 28 miles per gallon (of compressed natural gas). It comes with an at-home pump that you can use to tap into your home gas line to fill it up before you leave your home. However, since compressed natural gas isn’t likely to be available in all gasoline stations everywhere, you will want to carefully plan your trips if you’re going to use Civic GX. It may be one of the most fuel efficient cars but it can only travel 170 miles on a single fill-up.

Toyota Prius

Prius has always made it at the top of the list for the most fuel efficient cars from EPA. It has an overall fuel economy rating of 46 mpg, one of the lowest in the market these days. The mid-sized sedan features a spacious interior which has made it a crowd favorite as well. As one of the most fuel efficient cars in the market, Prius has an estimated annual fuel cost of $1019.

Honda Civic Hybrid

The Civic Hybrid features electric motors that maximize the potential of its small 1. 3-liter engine. It is another one of Toyota Prius’ direct competitors when it comes to rankings for the most fuel efficient cars. With an overall fuel economy rating of 42 mpg, one can easily surmise how it came to figure on the list for most fuel efficient cars.

Toyota Camry Hybrid

The Camry Hybrid has a fuel economy rating of 34 mpg which barely made it to the list of most fuel efficient cars today. Its battery pack, while a bit bulky compared with other models, is one of the main features that have made it figure in this roster of the most fuel efficient cars. It also features a fuel economy gauge that lets the driver know when its average mileage rises.

Nissan Altima Hybrid

The Altima Hybrid uses practically the same technology that the Toyota Camry Hybrid has but with a couple of different features. It also has an overall fuel economy rating of 34 mpg making it another one of the most fuel efficient cars among compact sedans. Altima is great to use for city driving. According to estimates, it fares better in the city when it comes to best mileage than when used on the highway. But with its superb engine performance, it has managed to maintain its place among the most fuel efficient cars available today.

Fuel Cells: Where Are They Needed Most?

December 17th, 2009

With global warming at the top of the agenda for most individuals and institutions fuel cells are gaining a lot of positive press with their potential to drastically reduce greenhouse emissions and save our dying planet.
There are numerous applications for this promising new technology however there are a few areas where it has the potential to change the way we conduct our daily lives massively. Transport and communications are two major industries responsible for greenhouse gas emissions seriously poisoning our atmosphere. If we could significantly diminish the amount of harmful waste these sectors give out then we would stand in good stead for a much improved o-zone layer.
As you probably know, fuel cells are our major hope for an environmentally friendly replacement resource for fossil fuels. The chemical reaction of combining hydrogen and oxygen produces water and during this process electricity is also produced which can provide power for an electric motor or any other device. The only by-product of this chemical reaction is water which of course can be reused in a multitude of more rewarding ways.
This revolutionary technology can be implemented into almost any vehicle imaginable, from family cars and commuter trains, to commercial airliners, boats and hovercrafts. If fuel cells could be integrated into all forms of public transport, buses, trams, tubes and trains then the United Kingdom’s carbon footprint could be shrunk considerably.
In regards to the communications industry there is a wealth of room for them to become part of. Smartphones with touch screens and large displays as well as a lot of other new media units with powerful capabilities could use micro fuel cells to power their demanding programs and operating systems. The development has risen in tandem with the development of nano technology, the two complimenting each other in the perfect fashion as they are adapted together for the appropriate applications in consumer electronics. Micro fuel cells can power laptops, mobile phones and all other portable media for days more than the current batteries that are employed. On initial testing they could power a mobile phone for a month and a laptop for a whole day without recharging. And this can be applied to any piece of handheld equipment imaginable, from digital video cameras and power tools to smoke alarms and hearing aids. On a grander scale fuel cells could replace batteries used for the national grid because they have the potential to provide power for telecom sites that require up to 5kW and without noise pollution or any other polluting emissions.
Hopefully we will see the increasing integration of fuel cells in to the appliances mentioned and greatly decrease the poisoning emissions that are polluting our environment so severely.
