It is basically, a kind of selling technique where potential buyers from your website are directed to the websites of sellers. For every click, the website owner gets a small commission.<br />www.onlineuniversalwork.comAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-13900197.post-5742800100043184242008-08-25T08:25:00.000-06:002008-08-25T08:25:00.000-06:00Mr. Poet,"the electronics being able to consume or...Mr. Poet,<BR/><BR/>"the electronics being able to consume or produce VARs on command.... oh, this has the potential to be a utility manager's wet dream". This is the single largest obstacle to the widespread successful commercialization of plug-in vehicles. Utility companies are well aware of all the grid benefits of demand curve leveling described in your well written article here. But they much prefer to modify consumer behaviors through cultural change, not more commercial engagement of consumers beyond their billing meters. They loathe the mere thought of interacting with consumers in real time because of the huge additional costs they would have to bear for all the extra customer billing management, and especially the in-home electronics to handle discrete real-time electricity transactions for vehicle charging.<BR/>It's too bad because consumers are accustomed to real-time discrete purchasing of most other consumer products, including other energy sources too like gasoline etc. As an electronics engineer I can also confidently claim that the electronics technology to realize this capability for utilities is not rocket science, and has in various forms already been developed. There is simply no easy way for utility companies to pay for it in their heavily regulated world, and as long as our sleepy regulators are afraid to change the ballgame for them, it will be a very long time before we see our utility companies embrace this sort of technology.Bob in Stoney Creek Ontariohttps://www.blogger.com/profile/05363069783334039803noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-1123765891208727852005-08-11T07:11:00.000-06:002005-08-11T07:11:00.000-06:00In your case, the 6.5 kWh/day maximum is roughly e...In your case, the 6.5 kWh/day maximum is roughly equal to your daily consumption for other purposes. Using vehicle-to-grid technologies the car could provide load-levelling on the supply as well as the demand side. (AC Propulsion has <A HREF="http://www.acpropulsion.com/white_papers.htm" REL="nofollow">a lot of information</A> on this.)<BR/><BR/>The total power shift available depends on the size of the grid connection, of course; you're not going to offset the draw of an electric stove with a connection through a 16-gauge extension cord. On the other hand, being able to manage demand by ±1500 W per vehicle on a time scale of seconds would be an enormous advantage for the utility; they could eliminate other spinning reserve completely and use their active capacity 100%.<BR/><BR/>You linked to a demand graph for Texas, showing a peak demand around 55 GW. I did a quick stats check and found that the population of Texas is about 21 million. If half of them are licensed drivers (perhaps an undercount) and there is 1 vehicle per driver, that's 10.5 million vehicles; multiplying by 1500 watts each, I get ±15.75 GW of potential grid regulation capacity.<BR/><BR/>Then there are the other factors, like the electronics being able to consume or produce VARs on command.... oh, this has the potential to be a utility manager's wet dream.Engineer-Poethttps://www.blogger.com/profile/06420685176098522332noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-1123731941417567882005-08-10T21:45:00.000-06:002005-08-10T21:45:00.000-06:00I think you're half right.

I got my numbers from the Energy Use Data Handbook:<BR/><BR/>http://oee.nrcan.gc.ca/corporate/statistics/neud/dpa/data_e/handbook05/index.cfm<BR/><BR/>One good thing about trying to model economic issues in Canada: Statistics Canada is the best.<BR/><BR/>Anyway, the amount displaced is correct, about 500 PJ is removed from oil consumption. But you're right, I forgot that the hybrid is flat out more efficient than the gas burner. E.g. it's a lower entropy or higher exergy process, take your pick of which flavour you prefer. As such, my estimates for the amount of scalable demand available to the utilities is too high. I'm not sure if that's good or bad. They need less extra production capacity but have less flexibility in the demand side.Robert McLeodhttps://www.blogger.com/profile/05270962906437456350noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-1123705924328328692005-08-10T14:32:00.000-06:002005-08-10T14:32:00.000-06:00I fear you've made the same mistake that I address...I fear you've made the same mistake that I <A HREF="http://ergosphere.blogspot.com/2004/08/you-find-you-get-what-you-need.html" REL="nofollow">addressed last year</A>. 11.5 kWh/day may represent the per-capita raw fuel consumption for transport, but the actual power output as work is much smaller. If you take your 30 km/day figure and multiply by 217 Wh/km (350 Wh/mile), you get a mere 6.5 kWh/day. That's about 270 watts, and that's the maximum. (A Prius+, at 162 Wh/km, would use quite a bit less.)<BR/><BR/>I doubt that BC could get huge amounts of energy from solar, but you seem to have hydro potential out the wazoo.Engineer-Poethttps://www.blogger.com/profile/06420685176098522332noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-1123701538065331722005-08-10T13:18:00.000-06:002005-08-10T13:18:00.000-06:00Sure, I'll add a link to your news blog in my link...Sure, I'll add a link to your news blog in my links section.Robert McLeodhttps://www.blogger.com/profile/05270962906437456350noreply@blogger.comtag:blogger.com,1999:blog-13900197.post-1123625171032739192005-08-09T16:06:00.000-06:002005-08-09T16:06:00.000-06:00Dear Sir, I have recently started a blog dedicat...Dear Sir,<BR/> I have recently started a blog dedicated to climate change.
