Hey, I'm a member of the solar car team from University of Toronto, we're also racing this year. Were you around for the 2007 WSC?
Unfortunately, I can't go to the race personally. You're lucky that you get to go as an alumni. Good luck to you guys! Say hi to the UofT team if you see them, they're a friendly bunch.:) (maybe a little disgruntled from the work and lack of sleep)
1) Current manufacturing process are struggling to get transistors any smaller than millions of molecules each, and Benzine, the molecule specifically used here, is not very big.
The current state of the art manufacturing process is at 32nm, which is much less than millions of molecules each. 32nm is 320 angstrom, so we're at roughly 300 molecules size.
I'm pretty sick and tired of people not reading articles properly. This is not directly totally at you, you just happen to be the last person among others. It's just depressing, and makes me wonder why I even provide links to back up my claims.
Anyway, from the article I linked to earlier, here are some important quotes:
"If you want to promote energy efficiency you don't subsidize the price of electricity, you've got to raise it," said Jack Gibbons, lead author of the study
Ontario Power Generation also gets a below-market return on its generating assets that amounts to $850 million annually.
"In essence, a full-cost pricing strategy represents a tax shift from subsidizing wasteful consumption to rewarding efficiency, which in turn is a much more economically efficient and beneficial use of government revenues," according to the study.
The rebate that's mentioned in the article is the new rebate scheme they want the subsidy to be replaced with, not the current subsidy. And you didn't answer my question, why would the rate be so much cheaper in Ontario versus other regions if there's no subsidy?
Just from first few results from google. Cost overruns from large power projects is of the reason why electricity rates is higher, but consumers don't see the effect of those cost overruns due to the subsidies.
Why do you think the rates are so much higher for regions? It's definitely not because we're that much more efficient.
Our electricity rate is subsidized by the government. If we pay for the actual cost of producing electricity, it would be comparable to what other jurisdictions pay.
What happens next in a fully interconnected North American grid is that quarter of a billion people lose power.
No, that's not true. Read all of my posts and not just focus on one small part of it. The August 2003 blackout could have been prevented through 2 ways. First way is following the NERC reliability policies, which FirstEnergy did not do. The second way is implementing situational awareness on the grid that would have prevented the blackout. This is currently being worked on after the recommendation from the joint task force report. The worst case that would have happened would be the area controlled by FirstEnergy goes without power, but it won't drag down the rest of the grid.
The risk management answer is: from any given local grid, don't routinely import or export more electricity than your local grid is capable of surviving should that import or export suddenly cease.
They already do that. That's the N-1 criterion I mentioned earlier.
One thing I can think of is that the AC transmission lines for the 3 different interconnect aren't all at the same location. There probably isn't a location where all 3 systems meet, and you need to have access to HVAC lines in order to transfer power to and from each system. So logical location would be somewhere that is closest to all 3 systems.
A big part of the cost of having DC line is the high efficiency and high voltage power converters to transfer from AC-DC-AC, which you need regardless where the location is.
And no, you can't get arc that's 5 miles long, that would be quite a sight though.:)
What insulation are you talking about? HVAC transmission aren't insulated at all. The advantage of AC over DC is that you don't need high efficiency high voltage power converters, which are very expensive compare to transformers. This is changing with advances in power electronics, but it's still more expensive than regular transformers.
HVDC is actually cheaper than HVAC on a per mile basis, but the power converters you need at the terminal brings up the cost. So for really long transmission, it starts to be more cost effective to use HVDC. One example is the HVDC on the west coast of US.
That's simply not true. The grid operates with accordance to guidelines set by the North American Electricity Reliability Commission (NERC), one of the policy is something called "N-1 Criterion". Which means any one single transmission line or generation unit can go down without affecting the grid. And NERC also requires that the operator balance the grid to satisfy N-1 criterion after one contingency happens. So it's not like once one unit trips, another unit trip would destroy the grid. Yes, balancing the grid after a contingency takes time, but the likely hood of 2 events happen so closely is low. Plus, the N-1 Criterion requires the grid to remain stable for the single WORST scenario, which many contingencies aren't.
The cause of the August 2003 blackout also was caused by improper procedure by FirstEnergy, along with lack of situational awareness on the grid. The joint task force report on the blackout concluded the blackout could have and should have been prevented by proper operating procedure. You can find the link to it at the bottom of that wiki page you linked to, or here: https://reports.energy.gov/
Yes, electricity travels fast, but that doesn't mean the grid is not operated to handle failures. BTW, this is my current research area, so I know at least a little bit of what I'm talking about. Not to make the logical fallacy of appealing to authority or anything.
I think there's still some benefit to making the residential customers paying the true cost of electricity. True, not everyone will change their behaviour, but some might try to do their laundry during off peak hours. The cumulative effect might or might be big enough to make a difference. However, even if it's not big enough, at least utilities get a bit more money, which is in desperate need to upgrade the ancient infrastructure we have.
Correct me if I'm wrong, but how does air change the flow of Eddy Current? For those of you not familar with Eddy Current, here's a short introduction.
Did xkcd just put together some buzz word and hoping that other nerds wouldn't notice?
How about number 88? Where's Waldo? by Martin Hanford. I tried, and failed, to think of any reason for that book to be banned. I mean, alright, I can accept that with millions of parents, you're bound to have some nutcases who'll have problem with any book. However, the fact that this book is on the top 100 most frequently challenge books just boggles the mind.
I apologize in advance for kind of hijacking your thread.
Here's a question. Is it legal to use the trial version of Office in a commercial environment?
The reason I ask is because I needed a newer version of Office to open a document that wouldn't open in Word 97. IT said they don't have the money to purchase a copy. Since I only really needed Office for that particular case, I used the trial version of Office. I made a point to check any legal restriction on it, but there wasn't anything I could find on the Microsoft website. Still, it bugs me. In my mind, I always thought the trial version was for non-commercial use.
I'll concede that it's not only marketing. Apple does make products that are well designed and easy to use. However, I still maintain that brand recognition and marketing are a big part of their success. Mention Mac or iPod and people do perceive them to be sexier than the competition, PC and iRiver for example. If you ask people about digital audito player, they would give you a blank stare. iPod is now synonymous with DAP.
I'm not trying to take anything away from Apple, they do make excellent products. But they do cater to a sector of the market that values the social aspect of a product. This is very different than the game AMD is playing. That's the point of my original post, not to try to belittle Apple's accomplishment.
If you look at Apple's current product (Mac, iPod, soon iPhone), the market they're selling to (brand conscious consumers), and the high margin on their products, they're totally different than where AMD is competing. AMD is selling processors to price conscious consumer, with an ultra low margin. This is especially the case now that Intel is doing some very aggressive price cutting. I just don't see why Apple would enter such a market.
Also, if you look at Apple's key to success in recent years, it's their ability to design products that are "sexy". I don't see how they could leverage that while designing processors.
I did something similar to that once, not to the same extent, obviously.
I bought the Commander & Conquer pack from Walmart, which included the original C&C + expansion, and RA + expansion. 2 out of the 5 CDs wouldn't work in my DVD-ROM, so I returned it for another copy, and this time, 2 different CDs refused to work. At this point, I gave up and returned the game completely. To this day, I still don't know whether the problem lies with the CDs or my DVD-ROM. I never experienced problems with other CDs though.
Stop twisting the word faith and giving it different meanings. A POW does not have "faith" that he will survive, he has "hope". Faith means you believe in something indiscriminately. If I'm in a very terrible situation, I don't BELIEVE that I will survive 100%, I HOPE that things will work out.
So your argument is really an argument for hope, not faith.

No, I joined after the 2007 race. But I've heard all the stories from the previous team members.
Yeah it would be amazing to go to the WSC, but unfortunately, other things get in the way. :(
Are you still in touch with the Michigan team?

Ontario pretty much has one the cheapest electricity rate in North America.

While you're correct that it's cheaper to have shorter superconducting DC lines, they don't seem to be that expensive. Their website indicates it's on par with HVAC lines: http://www.amsc.com/products/applications/utilities/superconductorpipeline.html
A big part of the cost of having DC line is the high efficiency and high voltage power converters to transfer from AC-DC-AC, which you need regardless where the location is.
And no, you can't get arc that's 5 miles long, that would be quite a sight though. :)
Correct, in addition to having a much higher capacity to transfer power with the new system.
What insulation are you talking about? HVAC transmission aren't insulated at all. The advantage of AC over DC is that you don't need high efficiency high voltage power converters, which are very expensive compare to transformers.
