But it only costs 4 to 6 cents per kilowatt hour to make on average, according to DOE's Energy Efficiency and Renewable Energy division – close to the ultra-cheap price of energy made from coal, but without coal power's massive carbon emissions.Unknownhttps://www.blogger.com/profile/05744310363709896138noreply@blogger.comtag:blogger.com,1999:blog-19408890.post-31254012679098001962008-03-11T06:48:00.000+11:002008-03-11T06:48:00.000+11:00omfg do u know wat hot rocks are or is this even j...omfg do u know wat hot rocks are or is this even just a site for watever?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-66723247184173139402008-03-11T06:43:00.000+11:002008-03-11T06:43:00.000+11:00i have a question- im doing geothermal hot rocks f...i have a question- im doing geothermal hot rocks for a science project and my question is "does the cost of this energy make it prohibitive for common use...why or why not?" well i know geothermal hot rocks cost 6 cents per kilowatt-hour and $1700 per kilowatt installed. why does it cost this little? i know it runs on a constant source of free fuel, but are there any other reasons? please comment back i need some help by today.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-37207745110171615672008-03-11T06:27:00.000+11:002008-03-11T06:27:00.000+11:00well i dont get how much it costs and why?well i dont get how much it costs and why?Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-81199224989930848012007-11-11T13:58:00.000+11:002007-11-11T13:58:00.000+11:00Has anyone asked why the radioactive decay occurs ...Has anyone asked why the radioactive decay occurs so deep underground? Would there be a natural purpose for the decay to occur well away from where we dwell? How would we feel if someone came to drill a well into our hearts to extract our endless supply of Love? <BR/>Seems to me like we can remember "what we do to our home, we do to each other" Baseload or none, what is our baseload and what is our respect for the natural purpose of decay occuring so deep beneath us? I'm deeply grateful that the decay occurs so deep undergraound to make this planet habitable. Let's explore some simple options before we make complicated and flimsy exploration.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-11098778506163102007-05-07T09:47:00.001+10:002007-05-07T09:47:00.001+10:00thanks a lot it helped me with my projectthanks a lot it helped me with my projectAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-17426883390438145132007-05-07T09:47:00.000+10:002007-05-07T09:47:00.000+10:00thanks a lot it helped me with my projectthanks a lot it helped me with my projectAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-69372529379202738792007-05-07T09:46:00.001+10:002007-05-07T09:46:00.001+10:00thanks a lot it helped me with my projectthanks a lot it helped me with my projectAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-48092921215549475932007-05-07T09:46:00.000+10:002007-05-07T09:46:00.000+10:00Thanks a lot it helped me in my science fair proje...Thanks a lot it helped me in my science fair projectAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-23209300687664078832007-04-24T07:38:00.000+10:002007-04-24T07:38:00.000+10:00thnx for your post. i had heard of geothermal, bu...thnx for your post. i had heard of geothermal, but i was not aware of any large-scale projects being planned.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-38737655907843937762007-04-14T19:51:00.000+10:002007-04-14T19:51:00.000+10:00I'm not sure how the geothermal guys plan to get o...I'm not sure how the geothermal guys plan to get over the significant economic hurdle of the distance from their plants to the grid. very pricey.<BR/>a carbon price, if it was high enough (the current models would really only lead to more gas being used), would naturally favour the cheapest alternative, which in the renewable sector is wind.<BR/>we need a price on carbon and a renewable energy scheme (ie.

Your science lecturer was likely discussing more traditional geothermal technologies with the HFR (Hot Fractured Rocks) technique being employed by Geodynamics. The beauty of HFR is that it takes place in geologically stable areas (i.e. no earthquakes or volcanic eruptions) and in areas which, based on the general geology of Australia, would be inherently low in corrosive minerals. Furthermore, if these minerals were present the recirculating system could easily be flushed with additional clean water and inhibitors if required. As I said, it has never been stated as an issue. <BR/><BR/>This technology is, in my humble opinion, the best single option that we have for producing zero-emission base-load power. I should also add that the known resource of hot rocks is probably only the tip of the iceberg and current estimates are very conservative. The amount of heat energy within the earth's crust is virtually infinite and in a process of constant renewal through natural radioactive decay. What's more, the technology to extract this heat already exists. It is about time that this technology is finally getting some of the attention it clearly deserves. Australia is in an extraordinary position to make good use of this outstanding renewable resource.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19408890.post-47777764490415613352007-04-12T15:02:00.000+10:002007-04-12T15:02:00.000+10:00I remember from my first environmental science cla...I remember from my first environmental science class years ago, that 'the problem with geothermal' was the impurities that is mixed in with the steam. I don't remember exactly, but I would imagine it's minerals that make it corrosive. Has anything in technology changed that has made it more viable, or is it the growing cost of other options?Anonymousnoreply@blogger.com
