The increase in the concentration of greenhouse gases in the atmosphere is truly alarming and is beyond dispute as they can be measured, minute by minute and they are.
From the CSIRO website, we see the statement
Since the Industrial Revolution (about 1750), global carbon dioxide (CO2) concentration has risen 37 per cent, methane 150 per cent and nitrous oxide 18 per cent.
To arrive at CO2 equivalents (CO2e) we need to multiply methane by 21 and nitrous oxide by 310 times. Nitrous oxide, because of its multiplier and adverse effects on human health may turn out to be the most important greenhouse gas. Possibly, it deserves our closest attention.
Two of the most important sources are power stations (coal or gas fired) and diesel engines Add in nitric acid production and you have the great bulk, particularly the great bulk we can do something to reduce. Same sources deliver the bulk of the CO2 and sulphates.
Australia has close to 30,000 megawatts (MW) of coal fired power generation which could cost $1,500,000 per MW, in total, to replace, utilising pulse combustion powered sine wave refrigeration to liquefy 100+% of ALL the greenhouse gases. The new power stations would LOWER the cost of power by one third if the gases were not captured and safely sequestrated, because they can produce 1.5 MW per tonne of coal, versus 1.0 MW at present. This is a profit of $21 at NEMCO wholesale rates.
Cost of liquefaction is estimated at $3.00 per tonne and safe sequestration under silts (no interface to the water) with 3,300 metres of water supplying the pressure, should be less than $10 per tonne, by pipeline. Actual amount is $18.20 for our 1.5 MW of electrical power, due to 1.4 tonnes of greenhouse gases. Still in front.
The bill for replacement of existing with new, clean, power stations is $45 Billion and removes 50% of total Australian emissions (Garnaut Report). The $10 B of Tony Abbott to subsidise interest rates will work, the $40 B of Kevin Rudd does the whole job. (Feb. 2010 figures)
Using our thermoacoustic refrigeration process, driven by pulse combustion, (PUTAR), Australia would save 250 billion litres of water annually and can export the technology with clean coal. The technology is proven, physical principles well known. Like amine capture and geosequestration, at a ruinous cost of $100 per tonne, scale up to power station size is required, is not difficult and is expected to add efficiency.
Lord Monkton (Melbourne address, 1st February) has referred to the brown haze over the China area, visible from the satellite photos and others have pointed out the white sulphate haze over India, particularly visible where it is pushed up against the Himalaya¹s.
It seems apparent that atmospheric pollution is a major ³cause¹ and climate change may be an ³effect². Perhaps best to tackle the ³cause².
Our PUTAR system can eliminate 100+% of all the greenhouse gases at no cost if correctly funded and give us bright clean power stations, generating cheap power to keep industries such as aluminium alive. Our standard of living depends on these matters. A description of the technology is herewith.
