With gas prices being so high, alternative fuel vehicles have become a popular topic. Two of the types of vehicles that tend to get a lot of press are the hydrogen fuel cell powered vehicles and electric powered vehicles. Both are lauded as the way of the future

But which of these two options are really has the better chance of being the car your children drive.

Lets look at hydrogen fuel cells first. When burned in an engine, the only emissions giving off is water, so a hydrogen powered vehicle is a zero emission vehicle. Hydrogen is also a better fuel than gasoline, it actually has the highest energy content per unit of weight of any known fuel.

Hydrogen is also a very abundant element. While current methods for making hydrogen are done by using fossil fuels, such as natural gas, coal, and oil, American wouldnt be dependent on foreign oil anymore. Also, hydrogen can be extracted from water, and we all know theres a lot of water on this planet.

However, hydrogen is not without its share of drawbacks. Probably the biggest problem right now is that it would require an entire new infrastructure. While gas stations could be outfitted with hydrogen fueling stations that would take years. Also, the technology to store hydrogen efficiently is still not ready for prime time.

Then theres the electric car. Electric cars can also be considered zero emission vehicles since they give off no emission when running. However, electric cars do require power from the electric grid, which does give off emissions. As the electric grid gets cleaner, though, so do electric cars, and electric powered cars are substantially less polluting than gasoline powered cars due to the fact that power plants are far cleaner and more efficient than an internal combustion engine in a vehicle.

The technology for mainstream electric cars is also not quite ready for all the major manufacturers to stop making gasoline powered cars, but its much closer than hydrogen currently is. The challenge with electric cars right now is the batteries. The batteries are both expensive and current models, like the Tesla Roadster, have a range of only 250 miles great for commuting, but not so good for road trips. The other problem is the length of time these vehicles take to charge. Its not simply a matter stopping at your local power station and plugging in for five minutes and leaving. A typical charging cycle for current prototypes is 4-5 hours again, fine if youre commuting, but impossible for a road trip. While technology is being developed to make charging your vehicle as quick as quick as filling up with gas, it has a ways to go before its ready, just like hydrogen fuel cells.

Fleets of electric cars will certainly be hitting the roads sooner hydrogen fuel cell cars, but which one ultimately ends up being the vehicle of choice for American drivers remains to be seen as both have plenty of challenges to overcome before people will readily give up their cheap gas powered cars in favor of these alternatives.

Up Your Used Car Value By Stopping Rust Part 1

fc8

Rust is rust. It's unsightly, it speaks of neglect and inevitable decay. And no one likes it. Certainly not on cars, whether used cars or new. After all, we want our cars looking shiny and brand-new, just as it was when it left the car dealer lot.

When it comes to buying used cars, no one wants to buy a rust bucket. Rust radically depreciates your used car's resale value. So, whether want to buy used car or a new one, the trick is keeping rust from taking root in your car.

Three basic steps are:

FIND RUST
KEEP IT FROM STARTING
ATTEND TO IT ONCE IT HAS STARTED

Most people shopping around at the used car dealer lot fail to detect rust simply because they don't know where to spot it. Of course, you can't expect the dealer to be upfront about rust in their used cars for sale. One needs to understand then how rust usually starts and where it is most likely to emerge.

How Rust Starts

Rust usually begins through the chips and nicks your car receives from the pebbles and stones that hit it during daily driving. With a small nick exposing bare metal in an unnoticeable location, it is just a matter of time until rust forms.

Left unchecked long enough, this tiny nick will eat its way through to the other side. When this happens you have problems because once a rust hole starts, it cannot be stopped. It can only be slowed down.

Where to Look For Rust

The most likely areas to check for rust are in and around the wheel wells, and on the fenders immediately behind the tyres. These are the war zones where your tyres will kick up stones and chip the paint. The front of your car can also catch flying stones from other cars, making this a problem area as well.

The next time you're looking at used cars for sale, use a torch to look underneath the car, and behind the front and rear tyres on both sides. Of course, before you do this make sure the car is parked on a level surface in park/gear and the emergency brake on. If it is on a slope, put blocks under the wheels for added safety. Shine your light on the inside of the fenders and wheel wells.

Another word to the wise for those who buy used car

Avoid cars with fresh paint. Think about it: no one paints a car just because the colour has faded a little. It was painted because either it was in an accident or it had a rust problem or worse yet - both! A crash repairer can hide a lot of sin with paint and body filler

Other rust-prone places to check when buying a used car are the exterior flooring under the driver's and passenger's seats, the interior flooring underneath the carpeting/matting, under the carpeting/matting in the boot, and around the engine compartment. Use your torch, your eyes, and your fingers!
