Most of those type of people hang out in Georgetown haha and I am glad they do as they don't muck up the cars and coffee crowd. Probably becuase they are just getting home from the club at that time lol

has anyone noticed the difference between certain frs hood weight? Last sunday at autox i opened my friends hood and his felt like it was made out of steel, pretty heavy, and mine just felt like light aluminum. Just curious if anyone knows why.

So, I've had a thought. People don't like the idea of an electric sports car because of the lack of engine roar, right? I wonder if it would be possible to design an electric internal combustion engine, without the combustion, of course. The batteries would power the pistons instead of the generator (or however it actually works, I don't really know) and the exhaust would just be normal air, but made to move through a system that produces a similar engine note.

Well there are cars that run on compressed air that might be able to replicate this kind of function. Last article/video I saw was some french company that made cars / vans that had carbon fiber air tanks (which would crack under impact rather than bursting as a safety feature). It's a concept I've always been interested in because it is absolutely green, economical refilling, and is safe.

*edit* Peugeot developing a hybri car that runs on air: http://www.livescience.com/26508-peu...essed-air.html

I don't think firefox likes this forum very much. My sig quote doesn't how up for me, and I can't quote people to reply to their posts. Either way, that compressed air car is pretty cool, though wouldn't that still be a hybrid? What I'm suggesting is a fully electric car, just with a reconfigured motor. Instead of it being set up however it is now, make one with a motor identical to a normal piston engine, run it with electricity instead of gas. I'm wondering they could run it the same.

I am not sure how familiar you are with how an engine or a motor works, and I definitely do not claim I am an expert on this field. However, I would like to convey what I think I know with regarding to this area.

So, what you are proposing, if I understand it correctly, is that you connect an electric motor to the crank that moves pistons in the cylinders with no explosion on fuel, while maintaining intake and and end pipe to such in air and pump out air through exhaust. The purpose of this setup is to produce *artificial* engine note for a purely electric car.

Some points I find this setup interesting:

1. It is understood that electric power needs to be conserved zealously with a pure electric car. What this setup does is to use some of the electric power to move parts that sucks/pumps air in and out with no direct impact to the power produced to the driving wheel. In other words, it wastes its power on moving parts for generating sounds. Wouldn't it be easier to synthesize the sound through hardware parts and speakers using the same electric power?

2. The engine note that we normally hear is generated mostly, I think, by the gas explosions happening within the cylinders. I think this is the case because if you lift off the throttle while in gear, you can hear little or no engine note because there is no explosion happening. So if this is the case, I would assume that by moving the pistons to suck/pump air, you will not be able to generate too much engine note that you hear with an ICE engine. I wonder the benefit of using this implementation is cost-effective.

Just my two cents.

Thanks for the in depth explanation, and you're right, I have very limited knowledge on the electric car motor. Actually, what I was proposing was running the piston engine with electricity and producing the power that way. The sound was a hopeful side affect, but I can understand the inefficiency of a sound-making leech being unappealing to an automaker.

I'm going to go ahead and guess an electric motor design is already more efficient than an electric piston design. I'm just musing here.

OK, I think it is feasible to setup circuitry and wires to *move* the piston in its reciprocal motion, just like that motor used in the reciprocal saws found in Home Depot. However, I do not think that is the best use of the energy to generate the mechanical motion. if the motor can generate the circular motion already, why bother with the piston and cranks and their associative loss due to friction?

Perhaps you might assemble videos and documents from the 'Net that make a compelling and persuasive argument for the dilemma faced by so many recent college graduates. You have the time, right? Sit down with your parents and watch your presentation. This is not to promote excuse-making, rather to promote understanding. And when they finally see, ask for their help. Recruit them.

You have enough stress trying to find your way in this world; you don't need your parents thinking you're a slacker.

Unless, of course, you ARE a slacker, in which case…

Very recently I again heard on National Public Radio (NPR) in the States that 50% of the recent college grads were unemployed, and fully half of the 50% that did find employment are under-employed and/or not employed in their field of study.

Now, I’m speaking of the USA. I know nothing of the situation in PR, but I'd be interested in learning. I could see how the PR economy would mirror the US economy in many respects.

Do you live in Puerto Rico?

Did you earn your engineering degree from a reputable engineering school in PR?

I'm a recent Civil Engineering grad and I have sent resumes left and right with no luck.

Have you been applying for jobs in PR or the US?

Companies rarely offer entry level jobs, and if they do, they require a minimum of 2 years experience (which basically defeats the point of entry level.

Yes. It's a Catch-22 problem faced by so many as they strive to get a start in their career fields. You must have experience to get the job you need to get the experience you need to get the job. Did that make sense? My head's spinning.

It's a problem.

I'm still on the fence about doing a masters degree, because if I do, I might fall in the "overqualified" segment.

That, too, can be a problem. You're right to be concerned, despite the astonishment of our friend @Anthony. Consider this, though: If you do get a masters degree (in whatever discipline), you can always omit it from your resume if that is to your advantage. Don't hesitate to omit that if you need to.

Never approach the job hunt with the attitude that you must "Tell the Truth, the whole Truth, and nothing but the Truth." Don't lie, but do not reveal anything that will hurt your chances.

No employer will EVER tell you the Truth, the whole Truth…

Never.

If they did, no one would take the job (for many or most jobs).

For example, it is said that people do not quit jobs … they quit MANAGERS!

No employer is about to tell you about the abusive bitch of a manager that you'll be working for, and how everyone who left that position you've applied for, went away mad.

That was my first thought too. Haha now I don't feel so scandalous about it.

LOL!

"A mind's a terrible thing to waste."

Perhaps it's time for you to consider taking that fine mind of yours to college, Anthony? Do they have a Lake Wobegone in Kentucky? I'm thinking that's where you're from... (Google as needed, Prairie Home Companion)

Doesn't the Air Force offer college studies?

University of puerto rico mayaguez is one of the top caribbean universities, it is one of the best engineering universities, where a the US universities are 4 yr, PR is a 5 year degree, 179 credit hours, sadly civil engineer is one of the most saturated jobs right now... which is why I plan on doing a masters in industrial engineering as a systems manager.
