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.

What will the electric potential energy be if one of the charges is completely removed and replaced by a nega?

The electric potential energy for two positive charges of magnitude q and separated by a distance r is U1. What will the electric potential energy be if one of the charges is completely removed and replaced by a negative charge of the same magnitude?

It will be -U1.

Potential energy is U = kQq/r

Where r is the distance between them, Q and q are the charges and k is a constant ( = 1 / (4 * pi * E0) …. E0 is the permittivity of free space)

In the equation all you’re doing is replacing Q with -Q, which just flips the sign once you multiply and you’re left with -U1.

Is it possible to do a full color change on a 67 Pontiac GTO?

I’m really into the ‘67 and ‘68 convertible models. The ones I’ve looked into are red and black, but I would love to get it painted a dark metallic blue with white racing stripes. Is it possible to do such a huge paint change?

Of course. im huge in the restorations and its easy on our older cars. It usually requires alot of work if you want a flawless show job. Taking the fenders and doors off to paint the doorjams, under the mirrors and door handles, etc. But it is ALOT easier to start with a nice straight car so body work is at a minumum

How to Find Parts for Your Subaru SVX

If you have the pleasure of owning a Subaru SVX, you are instantly drawn to this luxury car’s striking features and distinct look.

Although the Subaru SVX is well renowned as being dependable and reliable for the most part; this car does come with its own pitfalls and mechanical problems. The main issues most owners run into with a Subaru SVX are wheel bearing issues, transmission problems and even transmission failure. Having the transmission repaired on the SVX can prove to be costly and sometimes not worth fixing. Because the SVX is set in a higher weight class than most vehicles in its group it is also prone to having problems with warped rotors.

While all of these issues can be fixed, they can also be expensive, mainly due in part to the fact that the Subaru SVX is an imported vehicle and in order to find parts, you need to either see a Subaru dealer in your area that specializes in repair and maintenance or you need to order the parts from a reputable manufacturer. Either way it can be rather pricey.

There are other resources and places to look when you are in need of parts for your Subaru SVX and you can utilize these ideas to locate the parts you need to fix it yourself or to acquire the parts and then have a licensed mechanic finish the work and repair the Subaru SVX. This will save you hundreds of dollars.

Purchase the Parts Wholesale

If you happen to know someone who works for Subaru or works in their parts department you can easily purchase the parts you need for your Subaru SVX through them. You will need to have a licensed mechanic or someone knowledgeable with Subaru to do the repairs.

Your Local Subaru Dealer

If you are able to fix the Subaru SVX yourself or you know someone who can help you repair the vehicle, you can obtain the parts through your local Subaru dealer. The cost for the parts won’t be as cheap as if you were to buy them wholesale.

Internet Auction Sites

There are many popular Internet auction sites that you can bid on or even purchase the parts you need for your Subaru SVX. Not all auction sites need you to bid on the item you want, although if you choose this option, you can save hundreds of dollars and you also have the option to buy the product directly from the seller.

Online Vehicle Part Swap Sites

If you perform a simple Google search you can easily find online vehicle part swap sites. Here, many times there are sellers who are looking to swap their used or new parts for something else. This is great if you happen to have what the seller is looking for and you are short on funds.

Junkyards

Junkyards are a great way to find the parts you need for your Subaru SVX. You need to take into consideration that these parts are used and may need to be removed from the vehicle before you can purchase the parts.

Vehicle Auctions

There are several vehicle auctions available that auction off the Subaru SVX for rock bottom prices, this is a great way to get a back up vehicle or use the vehicle for parts to repair the Subaru you currently have.

By utilizing multiple resources you can easily find the Subaru SVX parts that you need to get your vehicle back and running in no time.

Luxury cars in family 7 seater – Top 5

Having a family and children usually means that you will need a larger vehicle, as a car 7. If you are a lover of the powerful luxury cars, then back in the days, it would mean that you are likely to make the sacrifice to give up your luxury car to go for a bore of 7 seats. But fortunately the family car 7 seats have evolved, manufacturers have added power and luxury categories of vehicles 7 seats. Below, I listed five of my favorite luxury family car 7 seats.

5 – Mercedes Viano

The Mercedes Viano, it is actually the longest of the five cars that I chose. To be honest, this is certainly not one of my favorites, because it looks like a truck. But however it comes with a bunch of gadgets and is extremely comfortable to drive and be a passenger in. The price is Viano from any less than £ 26,000. They come in a 3.0L V6 or 3.5 and have a certain speed excellent top 122 mph and 126 mph. The Viano comes with leather seats and you can have the options of the DVD player, rain sensor and electronic gates sliding. It also comes standard with re-arrangeble seats and large table with folded lift function and deploy.

4 – Mercedes GL-Class

If you are looking for a little more power and strength, the Mercedes GL is an excellent choice, although certainly not the cheapest. Prices for early GL just under £ 55,000. In addition to the Mercedes Viano comes with the GL-Class is a 4×4 vehicle and perfect for off-road when you go camping with the family perhaps. The GL has a V8 engine that can take this piece of metal 0-60 mph in about 6.5 seconds surprising.

3 – Audi Q7

href = "http://www.john-clark.co.uk/audi/new-cars/view/59/Audi-Q7"> Audi Q7 Dealer Aberdeen is where I went to see the Q7 and see that c ' is a 4×4 I could not imagine a better place than the Highlands to take this car on a road test. The Q7 is fairly priced and very spacious inside and a 3.0 diesel engine it leads effortlessly. Inside you get leather seats and a beautiful excellent sound system.

BMW X5-2

The BMW X5 is priced at around £ 45k. This is an excellent family of seven seats, which looks great and has power. The X5 comes with iDrive system BMWs. Drive Wise as you get a car that is after all a BMW and they really know how to drive a nice car. The 4.8-liter gasoline you give breakneck speed of one mph 140! Is a strong car and it feels safe to drive in.

1 - Hummer H2 Luxury

If you are looking for a luxury 7-seater with ample space and a little eccentricity, the Hummer H2 is the one to go. for around £ 40k, you can choose one of these giants up with a full leather interior and loads of gadgets, such as a drop down screen for rear passengers, drag the screens to Front seat passengers, is also a 4×4 if you want to go off on the beaten path.

Project Subaru

Project Subaru

Creation of the Universe – The theory and observation merged together can give us some answers – Observatins of the Black Holes in our Universe.

We have never seen them directly, yet we know they are there.

 

Lurking in dense star clusters, or wandering the dust lanes of the Galaxy were they prey on stars or even swallow plants whole.

Our Milky Way may harbor millions of these – Black Holes, the ultra dense remnants of dead stars.

 

 

But now in universe far beyond our galaxy there is evidence of something even more ominous, a breed of Black Holes that have reached incomprehensible size and destructive powers.

It has taken a new era of Astronomy to find these, high technology instruments in space tuned to find high energy forms of life with x-ray and gamma rays that are invisible to our eyes, new precision telescopes on earth with technology enabling them to cancel out the blurring effect from the atmosphere on earth and see to the far reaches of the Universe.

Looking into far distances of our Galaxies, astronomers finding evidence that space and time can be shattered by eruptions so waste they boggle the mind. We are just beginning to understand the impacts these outburst have had on the Universe around us.

That understanding recently took a leap forward when a team working at the Subaru observatory at the top of one of Hawaii’s volcano mountains looked into the deeper parts of the Universe and captured a beam of light that had taken almost 13 billion years to reach the earth. It was a messenger from not long time after the Universe is believed to have been born.  They focused their attention towards an object known as a Quasar, short for Quasi radio stellar Source, it offered a stunning surprise.

A tiny region of the object is so bright that the astronomers believe it comes from a single object with at least a billion times the mass of our sun.

In the center of this beacon the space suddenly turns dark as it is literary is swallowed by a black hole.

As strange as it may seem, even Hugh Black holes like these are thought to be products of familiar universe of stars and gravity.

They get their start in rare types of large stars at least ten times the mass of our sun. These giants burn hot and fast and they die young. The star is a cosmic pressure cooker. In its core the pressure gravity produces such an intense heat that atoms are stripped and re-arranged. Lighter elements like hydrogen and helium fuse together to form heavier ones like calcium, oxygen, silicon and finally iron. When enough iron forms and accumulate it begins to collapse under its own weight. That will send a chock wave that is sent outwards, literary blowing the star apart.  A supernova is born – at the moment the star dies, if enough matter falls into its core it collapses to a point forming a Black Hole.

Intense gravitational forces surround that point with a dark sphere – the event horizon at which point nothing, even not light can escape, that is how an average size Black Hole is formed.

What about the monster of the Subaru Quasar just recently observed? Recent observations about these giant black holes have led the theorists to re-think their views on history.

Back in 1995, the Hubble Space telescope was enlisted in to begin register details of that history.

Astronomers selected tiny regions in the sky between the stars, looking north, and south and into south again.

For days at a time they focused the Hubble telescope on these tiny patches of sky to examine the deepest regions in the universe. These deep field images offerings clear view of the cosmos in its infancy. What drew astronomer’s attention were the tiniest galaxies covering only a few pixels on Hubble’s lenses. Most of them do not have the spiral or elliptical shapes of the large galaxies we see closer to us today. Instead they are irregular and scrappy collection of stars. The Hubble Deep field confirmed the idea that the universe must have evolved in a series of building blocks with small galaxies gradually merging and assembling into larger ones. You can see evidence of this pattern by simply looking into the sky as many galaxies are gravitating around one another.  Some are crashing together; others are ripping each other apart. Gravity calls the tune as these galaxies draw together, exchanging stars and gases, and over time merge to form and form larger composite galaxies. Lately though, this picture of the Universe taking shape from the ground up has gotten a lot more complicated.

The quick appearance of giant black holes and galaxies in early universe is at odds with the gradual way matter builds up in most galaxies. They likely had their beginning in the first generation of stars that literary burst on to the cosmic scene, in a time of incredible turbulence. These stars were born in the knot that developed the fuse gas of the universe. Gravity drew these knots together, in the densest regions the stars were born in waves; they even gave birth to black holes. In a relatively short time by cosmic standards the earliest black holes swallowed more and more matter, growing to monumental proportions and became quasars. These quasars in turn were fed by collapse of matter on a much larger scale. Simulations of this illustrate what happened in the first billion years of cosmic history. Gravity forces driven by gases created an intricate web of strings and knots as if you were looking into a large spider web in three dimensions. In the densest regions are you would find the growth of the largest galaxies and black holes. 

As these regions grow stronger and stronger, the galaxies and black holes grow more and larger. In some regions these reach ultra massive proportions, billions of times mass of our sun. In the center of these massive galaxies, you will find developed a black hole driven by the galactic gravity of gases surrounding these galaxies.

The orbiting Chandra X-Ray Space laboratory was dispatched to look into the distant galaxies for black holes on a growths birth, those who swallow gases and summers, glow hot in x-ray light. And Chandra found them; it even spotted some of them in pairs. Black hole companion entwined in a dance of death, as when the music ends, the pair will swallow each other. That moment must be fast approaching for the largest black hole detected in the Universe up to date (or should we say has happened, as light takes some time to arrive here).

It is a quasar called OJ287, flare ups in the surrounding regions of this quasar suggests to the astrophysicists that another black hole is wandering around it. This giant gravitational hole and its companion have led astronomers to estimate it’s mass to be the enormous 18 billion times our sun mass.

A monster this large and ferocious vents its rage on its surrounding area and radically changes it.

Just look at MSO735, 2.5 billion light years away it appears in visible light to be a typical galaxy cluster. But in x-ray light it is in enveloped in a cloud of hot gas held together by immense cavities over a region of  600 000 light years across, in the radio wave light of the cluster, you can see two concentrated streams of matter pushing out from the center. This tells the astronomers that this is formed due to a rupture in the core of the central galaxy.  Two jets shooting out of the galaxy have launched a blast away through the gas of the galaxy; it is assumed that it requires energy of billions of super novas. This makes this the single largest eruption seen in our universe since the Big Bang. 

The source is a black hole that might weigh around 10 billion solar masses.  How is it that a black hole that is famous for hiding in the dark emit this much energy?

Think of the black hole as the eye in the midst of a hurricane storm, kept rotating by the gas, stars and all other matter surrounding its region of influence and other black holes that seem to fall into it. As this matter flows in, it forms a spinning donut feature called an accretion disc. It works like a dynamo, the spinning motion of that disc generates magnetic field that twist around and channel some of the inflowing matter outwards into a pair of high energy beams that projects out from the center of this jet donut.

How much energy, depends on the gravity and size of the black hole and how much matter has already crashed through its event horizon. Is this just another frightening specter of nature, or is it evidence of a more profound process at work?

Black hole jets have been seen all around the Universe, including in our own cosmic neighborhood.  Centauries A, also known as the hamburger galaxy exhibits jets seen in x-ray light, jetting out from its center.

Astronomers have come to believe its two galaxies in the act of colliding.

The famous M87 galaxy, at the center of Virgo cluster of galaxies, about 15 million light years away from us has been studied recently by the astronomers.

They have studied the 4 billion solar sun mass black holes that lurk in its hart. They found that in the tiny center of its region that the gas is whipped by its gravity to orbital speeds of millions of kilometers pr hour, which is powered by a jet that is penetrating into its center.

 

The largest black hole in the universe arose in the edge of quasars around 10-12 billion years ago, by releasing energy in form of jets they heated up the surrounding region. This prevented the gas from collapsing into the center from the surrounding region and allowed smaller galaxies on the periphery to form and grow.

But the monsters impact did not stop there.

The Chandra made a spectral image Hydra A galaxy cluster illustrates the high energy cavities forming jet streams blasting out from its central galaxy.

 

 

 

Gas on the edge of these jet streams contains higher content of iron and other metals probably from other supernovas from the explosions in the center. By pushing these heavier elements out into regions beyond the black hole seeds the universe with the elements needed to form stars, planets and solar systems like ours.

Then the smaller galaxies begin to seed their own environment.

As two galaxies begin their dance of entanglement and gas streams of each of these galaxies begin to interact, they feed each others black hole gravity field as they close up and at the same time push much of the loose gas beyond its boundaries. The final stage is a merge into one bigger black hole, as gas is sucked into these and creates a massive pull, in the final stages the singular black hole created by this collision emits one final blast of energy.

Our earth, sun and solar system seem to be beneficiaries of the black holes and their activities around in the universe.

The black holes are the evidence of the constant battle between energy and gravity in our universe.
