The hydrogen will then use fuel cells to produce electricity on demand. The wind farms can also sell hydrogen to motorists and other users.<BR/><BR/>Batteries are not needed, so there is no replacement expense.ronwagnhttps://www.blogger.com/profile/13449848231142723197noreply@blogger.comtag:blogger.com,1999:blog-19172410.post-19594118830803921582007-04-18T14:57:00.000-07:002007-04-18T14:57:00.000-07:00Great blog.

With large coal deposits near the railbelt it will be difficult to keep coal-fired power off the table locally. <BR/><BR/>While several regional power companies want to fund a wind farm, our local coop isn't interested in anything but coal and gas produced electricity. With the wind resources we have, if the technology could survive the beating and storage was available, it seems crazy NOT to look into wind power here. <BR/><BR/>Are 'plug and play' solar units available for the general public to use? I'd like to encourage our coop to 'rent' them out like the phone company used to lease us our phones. Customers would become part of the generating system. Couple that with inexpensive power shut off units for electrical appliances and information about conservation and we can make a much smaller carbon foot print.<BR/><BR/>Brooke Heppinstall<BR/>Palmer, AlaskaDiva One, and Diva Twohttps://www.blogger.com/profile/04208051716920686882noreply@blogger.comtag:blogger.com,1999:blog-19172410.post-22128312421821987842007-04-15T16:29:00.000-07:002007-04-15T16:29:00.000-07:00Some of the variability of PV and sources such as ...Some of the variability of PV and sources such as wind power can be ironed out by the use of a large-scale grid of highly-efficient 'HVDC' transmission lines. This allows solar electricity to be moved between time zones and, more generally, from areas of surplus to areas of shortage.<BR/><BR/>Utility-scale 'concentrating solar power' can store solar heat in melted salts so that electricity generation may continue at night or on cloudy days.<BR/><BR/>Further information about concentrating solar power (CSP) may be found at:<BR/><BR/>http://www.trecers.net/index.html<BR/><BR/>and<BR/><BR/>http://www.trec-uk.org.uk/index.htm<BR/><BR/>and <BR/><BR/>http://www.trec.net.au/Gerry Wolffhttps://www.blogger.com/profile/11460178635334918047noreply@blogger.com
