Oceans Could Slurp Up Carbon Dioxide To Fight Global Warming
ScienceDaily (Nov. 20, 2007) ”” Researchers in Massachusetts and Pennsylvania are proposing a new method for reducing global warming that involves building a series of water treatment plants that enhance the ability of the ocean to absorb carbon dioxide from the atmosphere.
About 100 such plants -- which essentially use the ocean as "a giant carbon dioxide collector" -- could cause a 15 percent reduction in emissions over many years, they say. About 700 plants could offset all CO2 emissions.
I don't follow your argument that widespread use of solar HWS will drop baseload power demand by 20%. Household hot water is no more than 10% of total electricity consumption in Australia so the likely reduction from going solar is 6 - 7% not 20%.I am wondering what ASX stock is mostly closely correlated with manafacture of Solar Hot water systems.
I have done a little research but cant seem to find out.
My rationale is that, to my understanding, one of the quickest and easiest ways to "reduce greenhouse emissions" is to install solar hot water, as this drops the baseload power demand by up to 20%
This means new coal fired power plants dont have to be built, just to keep up with increasing demand.
Now that we have a change in Govt, Kyoto to be signed,etc, Greens strong in Senate, probably means action may need to take place.
Examples: LPG vehicle installers have a waiting list, as do suppliers of water tanks.

Global warming affects more than power generation. LYC,a company develloping a rare earths mine will benefit greatly as it's product is used in many power saving devices. LYC is one of the very producers outside China. ( check out the LYC Lynas Corp thread.)
.
Gas-fired powerstations will take priority over existing coal-fired...Coal seamers as a feed for these will benefit. AGL & Babcock & Brown seem to be headed for a competition to secure the key assets...

CSG's East coast promise

READ Holland reckons coal seam gas explorers have really only begun to scratch the surface in eastern Australia, despite industry growth.
A former director of the School of Mines and Energy Development at the University of Alabama, Holland has been in the coal seam gas business since 1981, when it was in its infancy in the US.
As a consultant and principal of JR Holland and Associates, he has little doubt about the viability of such planned projects as Santos' and Arrow Energy's Gladstone LNG plants – at least in terms of their being enough gas to justify them. Indeed, he sees the possibility of coal seam gas spawning a significantly bigger LNG industry on the east coast.
Holland has consulted, off and on, on coal seam gas issues for nearly three decades and is here interpreting data for Eastern Corp, which has coal seam gas exploration areas in the Galilee Basin in central western Queensland.
Exploration is in areas once held by the ill-fated US energy trader Enron and is in its early stages, with Eastern having had a long wait for a rig to begin its latest single hole drilling program, which was completed in July. Galilee coals are deeper than those in the Surat Basin and have "some issues", says Holland. "But the Basin has very great potential. There is a very significant coal resource there."
When Holland moved to Alabama in 1981, he says there were 56 CSG wells in the state – all but six being primarily aimed at draining gas from coal so it could be more safely mined.
"There are now 5000 producing wells in the state's Black Warrior Basin, with Alabama producing 35 per cent of all US CSG – with the San Juan Basin of northwest New Mexico and southwest Colorado being the other major producing area.
"Coal seam gas now accounts for 10 to 15 per cent of total US gas production, and growing", he says. "Without CSG, the US gas price would be $US10 a gigajoule, rather than $US7."
Lobbing in Alabama to establish the mining school's research facility was fortuitous for Holland. Alabama University, during the US Civil War, was sacked and partly burned by Union troops. As part of post-war reparations, the university was granted the rights to significant coal areas – giving Holland and his team of researchers a flying start.
"From those 56 wells, it's become an international industry; it is an amazing story.
"Queensland looks to me like Alabama in its early days. Once this industry reaches a threshold, it grows exponentially," he says.
But there's a cautious note and he says CSG "obeys the 20-80 rule". "You get 80 per cent of your gas from 20 per cent of your wells."
Herewith a couple of excerpts from magazinse about CFL compact fluorescent lightbulbs - and the fairly minor publicity given to the fact that they have mercury, and cannot be simply discarded in the rubbish.
a) one is from treehugger
b) the other from another website, NPR , "CFL Bulbs Have One Hitch: Toxic Mercury"
I understand that disposal of these is treated much more cautiously in Europe.
Meanwhile Malcolm Turnbull continues to push them without this warning.

It will be doomed to failure if it doesn't tackle both emissions AND peak oil / peak gas at the same time.Well.
The BIG DAY of the Garnaut Report has arrived. Let's see where this (and the Government's response) takes us .... and the companies of Australia!
Well.
