PostHeaderIcon Electric Cars and Rising Gasoline Prices

Rising gasoline prices may just make other forms of alternative means of transportation become more attractive. One of the ways not to be affected by the rising prices of gas is to have an alternative means of travel. Of course, saving up on gasoline use may help in some way, but such actions may still leave one affected with the rising prices of gas. A better way would be trying to use a mode of transportation aside from one that makes use of fuel aside from gasoline. One such example is the use of an electric car.

An electric car is one type of an alternative vehicle. It makes use of electricity as its primary power source. Instead of an internal combustion engine, the electric car, also commonly called as an EV or electric vehicle, has an electric motor to make the vehicle move. It is an alternative fuel vehicle that does not use refined fossil oil for fuel.

Electric cars get electricity for power by means of electric battery packs built on board. One of the advantages of using electric vehicles or EV’s is that they are environmentally friendly. Unlike fossil fuel that emits a number of pollutants into the air when being used, the use of electricity for power does not do so, except that the power plants that may produce them do. But with using electric cars, the emission of harmful pollutants may be reduced substantially. Less cars using fossils fuel and gasoline would help make this possible. And someday, when more electric power is sourced from nuclear, solar, wind and hydro-electric power plants, pollutant emissions will even be reduced more.

Performance-wise, electric cars offer smoother and noiseless operation that cars relying on gasoline. Electric cars provide stronger acceleration and the electric motor requires lesser maintenance than the internal combustion engines of cars using gasoline and other fossil fuels. By using electricity through batteries, energy conversion is more efficient. Electric motors makes use of 75 percent of the chemical energy converted into electricity to run the car. Internal combustion engines or ICE’s only are able to make use about 20 percent of the energy stored in gasoline to power the vehicle.

If most think that the electric car is a recent invention, then they are mistaken. The electric vehicle is in fact one of the earliest vehicles known to exist. Small electric powered vehicles even predate the development of the diesel and gasoline engines. The earliest electric carriage was built between 1832 and 1839. The development of other electric cars also increased for some time during the 1860′s along with the improvement of the storage battery. It was even the electric cars that held many of the speed and distance records during this time. But unfortunately, the advent of the internal combustion engines came during the early 1900′s, which led to the decrease in the use of electric cars.

With the appearance of the more powerful and affordable diesel and gasoline powered cars starting in the early 1900′s, the market for electric cars slowly disappeared. Although there were still electric cars being made, those that do exist were being produced for specialized applications. One of the most common use for the electric vehicle today may be found in the golf carts as a primary mode of compact transport in golf courses. But because of the rising gasoline prices as well as the worsening pollution, there has been an renewed demand for the less polluting alternative electric vehicles in recent years.

PostHeaderIcon Energy Costs of Driving Electric Cars

The media are full of news about electric cars. The $100,000 Tesla electric sports car is going to be sold soon, automakers are falling over each other to announce new electric vehicles, and entrepreneurs across the world are jockeying for venture capital.

Petroleum prices have jumped during the last year and everybody is feeling the pain at the pump. Not a single soul is concerned about filling up the batteries of his next electric car with electricity. After all, you just plug the car into the next receptacle and there seem to be no appreciable costs.

Joe owns a Corvette, a high performance car manufactured by General Motors, which according to the car manufacturer drives 25 miles per gallon.

Joe’s monthly commute is 1000 miles, he drives very carefully, and actually achieves 25 MPG on his daily trip going to work and running errands. At $4.00 per gallon at the pump he is paying $160 for gasoline every month.

Joe is thinking about buying the Tesla, an electric sports car. He tried to find the cost of electricity for driving this car. He could not find any data anywhere. Joe knows that he must explain to his wife why he needs to save energy and money before buying the Tesla, a new, very fast electric sports car.

The Tesla will accelerate faster than his Corvette. There is no doubt that an electric vehicle can have a faster acceleration than a gasoline car. Electric motors and liquid fuel engines are just two different devices converting electric energy or petroleum fuel energy into mechanical energy. Electric motors can generate much higher torque at the wheels at much lower turning speeds.

In comparison, electric motors will have several shortcomings, too. They certainly will emit more pollutants and more carbon dioxide as long as coal is used for producing electric power. Overall energy efficiency of the electric car, from power plant to the road, is still worse than that of a modern automobile propelled by an advanced combustion engine.

The biggest drawback of electric cars is the small number of miles they can drive after a complete recharge. Additionally, the charging of an empty electric battery will take forever, high performance batteries are expensive, and will only have a limited life expectancy.

What about energy costs for driving an electric car compared to a gasoline powered car? Both vehicles will have to store energy. The electric car stores electric energy in its battery, the combustion engine powered car stores energy in the form of gasoline or diesel fuel in its fuel tank.

Now let us take a comparative look at the cost of storing and paying for enough electric energy or liquid fuel energy to drive 100 miles. Let us assume that both cars will have the same power requirements to drive 100 miles. In this respect the match-up between Tesla and Corvette is perfect. But how do we compare prices at the gas station with utility costs at the receptacle?

Energy contained in gasoline can be converted into mechanical energy only at the limited energy conversion efficiency of a typical heat engine. The Corvette engine will have an energy conversion efficiency of about 35%. (Fuel fired engines may eventually reach 50% peak energy conversion efficiency after decades of future advancements). Conversion efficiency of electric power from the receptacle into stored energy first and into mechanical energy later is much higher at about 85%.

The energy content of gasoline is 131 MJ/gallon (megajoule per gallon). For driving 100 miles the Corvette will burn four gallons of gasoline or 524 MJ/100 miles. Only 35% of the energy in gasoline or 183 MJ will be used to propel the Corvette. This is the mechanical energy transmitted to the rear wheels of the Corvette. Virtually the same amount of energy must be transferred to the wheels of the electric car, the Tesla. Both cars are very similar in size and driving characteristics.

However, the Tesla has to take a little more energy from the receptacle because the charging, storing, and discharging of electricity in the battery experiences energy losses. These losses are about 15% of the electric energy taken from the receptacle and will not be available at the wheels. The Tesla owner will, therefore, pay 1.15 times as much to get the same energy to the wheels as the Corvette or 211 MJ per 100 miles. Electric energy is priced in the form of dollar per kilowatt hour or $/kWh. The average price of electricity in the US is $0.09/kWh. The factor for converting energy measured in MJ to energy measured in kWh is 0.2778 kWh/MJ.

To drive 100 miles, the Tesla will consume 58.6 kWh of electricity at a cost of $5.28. The Corvette will consume 4 gallons of gasoline at a cost of $16. Now we know that the Tesla will save about $10 per 100 miles or $10,000 over 100,000 miles.

The Tesla will cost $100,000. The Corvette is priced from $50,000 to $75,000. Guess who gets the square deal with the roar of the engine as a free bonus.

PostHeaderIcon How Electric Car Works

Electric cars are shown up in the news nowadays. The hybrid vehicles and especially the electric cars are talk of the town. The electric car is the best alternative for the petroleum cars. The reason for this includes many statements. The electric cars have a lot of advantages over the old fashioned petroleum cars. The popularity of the electric cars has reached almost all over the world. We are taught in schools about the alternative sources of energy. The alternative sources of energy are solar energy, gas energy, electrical energy, etc. The electric cars are the cars which can run on electricity. Actually the petroleum cars can also be converted into electric cars. It is very easy to convert a petroleum car into electric cars. Most of the petroleum cars are being converted into electrical cars as electrical cars is cost cutting.

It is almost not difficult to understand how an electric car works. The architecture of the electric car is quite different then the petroleum car. A electrical car is consist of lots of wiring. The electrical car has following main components:

Electric Motor
Motor Controller
Batteries

An electric car is powered by an electric motor while a petroleum car is powered by a petroleum engine. This is how an electric car defers from the petroleum car. Instead of a petroleum engine an electric motor is placed inside the electric car. The electric motor gets power from the controller. Number of rechargeable batteries provide power to the controller.

The controller gets the power from the batteries and gives it to the motor. The accelerator pedal is tied with a pair of potentiometers (variable resistors), which provides the signal for the controller how much power it is to to deliver.

The 300 volts dc current is inoput to the controller from the battery and  controller converts it into a maximum of 240 volts AC, three-phase, and  sends to the motor. Inside the controller there is a transistor which turns onand off rapidly. A connector connects these two potentiometers and the padal, when you push on the gas pedal, The controller gets information about how much power to deliver to the electric car’s motor from the potentionmeters. There are two potentiometers for the sake of safety. The controller checks the readings of the both potentiometers to be equal. If they are not, then the controller stops operating. When accsilator is pressed, the controller turns the switch on, and when it is removed, it would turn it off.

The batteries are the main sources of power for the electrical car. Number of rechargeable batteries provide power to the controller. The motor can use both AC and DC batteries. Batteries  run by chemicals such as lithiuem. You can recharge the batteries by just plugging in the wire to the electric socket.

In this article we discussed about the architecture and working of electrical cars. Hope that this information increased your knowledge about the electrical cars.

PostHeaderIcon Buy Electric Rc Airplanes

Electric remote control airplanes are best for beginners.

The power of RC electric flight is amazing, not to mention much easier to own and operate :) With glow engines there is the problem of maintaining them and making sure they are up to snuff.

Over my years as an RC pilot, I have found that beginners and advanced pilots both seem to like electric RC airplanes, so it is a great idea to buy one as your first airplane.

Simple electric RC airplanes, like the Sky Vector shown below, are great because they are very easy to fly, and you really only have too master two controls. One control being the speed and the other being the direction you want to move in.

One of the best things about airplanes like the Sky Vector though, is the fact that they can be ready to fly within 15 minutes of opening the box! Basically, it is a no hassle approach to flying RC airplanes, which is what most beginners like and need.

Electric RC trainer airplanes are also available for people who want to actually train with electric airplanes, because that is all they intend to fly.

Important Electric RC Airplanes Reminders

There are many types of electric rc planes you can choose from. There is your regular electric rc airplane, then there are park flyers and slow flyers and some rc jets that are powered electrically. Park and Slow flyers are great for some fun flights in your back yard, or any local park. Electric r/c jets are very fast and fun to fly too. Follow those links to learn more about them.

Before a beginner decides to purchase an electric rc plane, you should keep these two things in mind:

1. Wings should be high up on fuselage

2. Should be an electric trainer that is RTF or ARF

Having the wing high up on the fuselage creates more stability, and RTF’s/ARF’s are easy to put together and start flying.

Below is a list of equipment that every beginner should have to make there electric rc plane work properly. A RTF and ARF kit usually includes everything needed with your purchase. Just go through the list to make sure you have it all.

airplane kit

electric motor and speed controller (maybe propeller too)

battery pack and appropriate charger

radio transmitter (AA or AAA batteries) and receiver

Just a reminder, always look for “not included”, and be sure to purchase what is not.

Why Choose Electric RC Planes?

Electric rc airplanes are easy to use, simply charge the battery and fly. Flight time can be anywhere between 10 to 30 minutes per charge. Buy an extra battery pack and fly for over an hour!

Electric powered rc airplanes are quiet, allowing you to play without neighbors complaining about the noise.

Electric rc airplanes are less complicated than gas models, best for beginners.

There are many ups and downs to electric rc planes. Let’s look at them now.

Electric RC Plane Pro’s Electric RC Plane Con’s

quite

cheaper

environmentally friendly

easy to fly

easy to fix and replace parts

slow (some exceptions)

short flight times

not realistic looking or sounding

Basically, if you are looking for just some quick little flights every once in awhile, then electric r/c airplanes are perfect for you. If you want to get into faster more advanced airplanes, then I suggest you check out gas and jet rc airplanes.

Equipment for Electric RC Airplanes

Electric RC airplanes just need the following:

rc airplane kit

electric motor

battery pack for electric motor

charger for the battery pack

radio control system

12 AA sized batteries for the radio control system

The best part is that most ready to fly rtf rc airplanes come complete with all these items. Just charge the battery, find a clear field, and fly!

Cheap Models

There are cheap rc airplanes for sale that costs only $49.99. There are also great beginner and ready to fly models that cost anywhere from $69 – $342 USD.

Click here for a list of cheap rc airplanes sorted according to sale price.

Brands

Manufacturers such as Hobby Zone, Megatech, Vortex, Hobbico, and Nikko sell ready to fly rtr electric powered rc airplanes.

Click here for a list of electric rc airplanes sorted according to brand.

What Model to Buy?

For beginners who want to fly immediately, I suggest buying ready to fly rtf electric rc airplanes. RTF a cheap rc airplane that come complete with all needed equipment.

Electric Motors

Electric rc airplanes operate on a electric motor and it is powered by a battery pack. Electric motors are nothing fancy, and are cheaper then glow engines. So far my experience with electric motors has been great. I don’t think you will have any problems either, as long as you take care of your electric motor and try not to crash.

Let’s Start Flying!

Any beginner can fly electric RTF and ARF rc airplanes. If you want to learn to fly your plane, I suggest you buy a good rc airplane book and practice flying your electric airplane. Since there slower and cheaper then gas rc airplanes, it’s okay if you make some mistakes. If you still think you might need help flying your rc airplane, then visit my learn to fly page.

First, you need to focus on choosing the right airplane. Before you start spending money, ask yourself these questions:

much do you want to spend?

How fast do you want your airplane to go?

How far do you want it to go?

Do you want a scale model (realistic model) or a non-scale model?

After you have answered those questions above, you can start looking for the right plane.

What else will you need?

I think every rc airplane pilot should have a field box. There great for fixing some problems you might have out in the flying field. If you want to have a longer flying time with electric planes, you might want to think about buying an extra battery. For even longer flying times, you could buy a car charger for your rc airplane battery. This way one can charge why you use the other. Check out my parts and accessory pages to find these items.

Something every beginner should consider buying is a good book or subscribing to an electric rc airplanes magazine.
