Ok I'm starting on me 2nd essay. I hope i did better. i still need to add some Quotes. But i was hoping to get this part prof read, If thats ok.

It's compare & contrast essay and it has to be 8 paragraphs.
In MLA stile and double spaces between lines.

Internal Combustion or Fuel Cells Running Electric Motors
Hydrogen and how to use it to run our cars. Right now our cars run on gas so how can we convert to Hydrogen. The first problem being distribution and production of hydrogen so we can buy it at the pump. Witch can be accomplished buy using solar or wind to make power and use it to make hydrogen, can also use the power to supply our homes too. Then building pipe lines to distribute it.

Now how to run our cars with it. One perfect solution it hydrogen fuel cells running electric motors; Another perfect solution is hydrogen internal combustion engines; On the basis of cost, Performance, and implementing, The hydrogen internal combustion engine is the preferable solution.

Hydrogen fuel cells running electric motors are not vary cost effective. First off you cant just convert your car to use fuel cells running electric motors you have to buy an whole new car. Who can afford to buy an whole new car just to convert to hydrogen.

In comparison internal combustion engines that are converted to run on hydrogen are cost effective. Fuel injection engines can run on hydrogen just the way they are, all you need is a new gas tank. Now they are a lot more efficient

Now when it comes Performance Hydrogen fuel cells running electric motors are not that great in terms of torque. Have you ever seen an electric car try to make it up a steep hill. it don't make it vary far does it. It will get part way and just site there, thats lack of torque. Electric motors don't have much torque. Thats why you don't have electric motors in trucks. they need to pull heavy load, And electric motor just cant do the job.

On the other hand when it comes to Performance of Hydrogen internal combustion Engines they are just as good as one that runs on gas. Any thing a gas powered internal combustion engine can do a hydrogen powered engine can do. Ford motor company is working on a Hydrogen internal combustion engine that is more efficient fan the gas powered internal combustion engine.

When it comes implementing Hydrogen fuel cells running electric motors there is still a lot of work to be done. First off to get every one using them every one would have to buy new cars. You cant easily convert your internal combustion engine to Fuel cell running electric motors. You would have to remove the engine, drive shaft and axles so you can put in the electric motors, One for each drive wheel.

Hydrogen internal combustion engines on the other hand are not that hard to implement. You wont have to buy a new car as long as your can has a fuel injected engine it can just be converted to run on hydrogen. In fact they can run on more then one fuel, According to Richard Truett

The supercharged V-10 engine has what Ford calls a tri-flex fueling system that enables the engine to run on hydrogen, E85 ethanol or gasoline. Cruising range between fill-ups is 500 miles. The driver can change fuel sources by using a switch on the instrument panel. (Truett 22)

Now that we have looked over hydrogen in internal combustion engine and in fuel cells running electric motors. And on the basis of cost, Performance, and implementation, The hydrogen internal combustion engine is the preferable solution. Thanks for listening

Greetings!

You do a good job of explaining the difference between hydrogen electric motors and internal combustion electric motors. Very interesting!

One thing that might help with your punctuation is to read your essay aloud to someone. Come to a complete stop at every period, and only pause slightly at a comma. In this way, you (or your friend who is listening) should be able to hear if the periods and commas are in the right places for your words to make sense.

Also, make sure that when you ask a question, you end your sentence with a question mark. "Right now our cars run on gas, so how can we convert to hydrogen?" and "It doesn't make it very far, does it?" (There were a number of errors in that sentence; compare my version with yours.) However, normally, one does not address questions to the reader in an essay like this. If you are presenting it orally to the class, though, that's probably fine.

You have a few misspellings of the sort that spell check won't catch, because they are also real words -- just not the right words. :-) "Witch" should be "which" ... and it should come after a comma, not a period; you have a sentence fragment.

Go through your essay very carefully and make sure that all your sentences end with the appropriate punctuation mark and start with a capital letter. Do not capitalize nouns that are not proper nouns, like hydrogen and performance.

You have quite a few sentence fragments like this: 'Now that we have looked over hydrogen in internal combustion engine and in fuel cells running electric motors." -- Now that we have looked them over ... what happens? It will make sense if you take out "that" and connect your two fragments, like this: "Now we have looked over hydrogen in internal combustion engines and in fuel cells running electric motors, and on the basis of cost, performance, and implementation, the hydrogen internal combustion engine is the preferable solution."

You have a bit more editing to do, but stick with it and you'll have a fine essay!

Thanks for all the help.

Ok been working on it. Hows it look?

Internal Combustion or Fuel Cells Running Electric Motors
Hydrogen and how to use it to run our cars. Right now our cars run on gas, so how can we convert to hydrogen? The first problem being distribution and production of hydrogen so we can buy it at the pump, which can be accomplished by using solar or wind to make power and use it to make hydrogen.

Now how to run our cars with it: One perfect solution is hydrogen fuel cells running electric motors, Another perfect solution is hydrogen internal combustion engines; On the basis of cost, performance, and implementing, The hydrogen internal combustion engine is the preferable solution.

Hydrogen fuel cells running electric motors are not vary cost effective. First off you cant just convert your car to use fuel cells running electric motors you have to buy an whole new car. And with the cost of cars nowadays, Who can afford to buy an whole new car just to convert to hydrogen.

In comparison internal combustion engines that are converted to run on hydrogen are cost effective. Fuel injection engines can run on hydrogen just the way they are, all you need is a new gas tank. Of course if you adjust the fuel metering system it will be allot more efficient.

Now when it comes to performance hydrogen fuel cells running electric motors they are not that great in terms of torque. Have you ever seen an electric car try to make it up a steep hill. It not going make it vary far. It will get part way up the hill and just site there, thats from lack of torque. Electric motors just don't have much torque. Thats they don't put electric motors in trucks, They need to pull heavy loads, And electric motor just can't do the job.

On the other hand when it comes to performance of hydrogen internal combustion engines are just as good as one that runs on gas. Anything a gas powered internal combustion engine can do a hydrogen powered engine can do. Ford motor company is working on a hydrogen internal combustion engine that is more efficient than the gas powered internal combustion engine. Hydrogen internal combustion engines can be allot more efficient then gas internal combustion.

When it comes implementing hydrogen fuel cells running electric motors there is still a lot of work to be done. First off to get everyone using them, everyone would have to buy new cars. You cant just easily convert your internal combustion engine to fuel cell running electric motors. You would have to remove the engine, drive shaft and axles so you can put in the electric motors, One for each drive wheel.

Hydrogen internal combustion engines on the other hand are not that hard to implement. You wont have to buy a new car as long as your car has a fuel injected engine it can just be converted to run on hydrogen. In fact they can run on more then one kind of fuel, According to Richard Truett

Now that we have looked over hydrogen in internal combustion engine and in fuel cells running electric motors. On the basis of cost, performance, and implementation, The hydrogen internal combustion engine is the preferable solution. Thanks for listening and may your car soon run on hydrogen.

Greetings!

I like your new ending! :-)) Here are some more suggestions:

"The first problem being distribution and production of hydrogen so we can buy it at the pump, which can be accomplished by using solar or wind to make power and use it to make hydrogen." - If you'll change "being" to "is" this won't be a fragement.

You still have quite a few instances of capital letters where they don't belong. For example:

"One perfect solution is hydrogen fuel cells running electric motors, Another perfect solution is hydrogen internal combustion engines; On the basis of cost, performance, and implementing, The hydrogen internal combustion engine is the preferable solution." - You have two capital letters after commas and one after a semicolon. Change your semicolons to periods and change the capital "T" in "The" after "implementing."

Also, I'm not sure that either solution is "perfect." You should consider removing that adjective. Go through the essay carefully and check all the places you have a capital letter after a comma. Either make the comma a period, or make the capital small, depending on the meaning of the sentence.

"Now when it comes to performance hydrogen fuel cells running electric motors they are not that great in terms of torque." - While it may sound perfectly normal to start a sentence with "Now" when giving a speech, it really does not belong in an essay. Consider removing all instances of it; you have several. Also, don't follow a noun with a pronoun that refers to the same thing: "electric motors they"; take out "they."

"It will get part way up the hill and just site there, thats from lack of torque." - should be "It will get part way up the hill and just sit there; that is from lack of torque."

"allot" should be two words. I see this mistake a lot. ;-))

"You wont have to buy a new car as long as your car has a fuel injected engine it can just be converted to run on hydrogen." - this is a run-on sentence. Put a period after "new car."

"Now that we have looked over hydrogen in internal combustion engine and in fuel cells running electric motors." - this is still a fragment; it needs more:

"Now that we have looked over hydrogen in internal combustion engines and in fuel cells running electric motors, there is one solution that stands out."

Keep up the good editing work!
