The Cost of Electricity Will Rise If Electric Car Ownership Increases

There isn't much doubt that as people adopt alternative means of transportation and relinquish the hold that the internal combustion engine has over us that costs will increase for alternative "fuels". A hope for the future is electric cars, the cost now being only a fifth of comparable petrol or diesel vehicles. If the majority of the population actually do buy electric cars the supply of electricity will have to be increased. More power stations will have to be built.

The Japanese accident shows that nuclear is no longer an option for future power generation. This means more pollution from coal and oil power stations. Electric cars are not an easy solution to the pollution problem. It is just a cheaper means of transportation, for the present.

The market always pushes up the price of alternatives. Households in the future will have a hefty electricity bill for lighting, heating and so on of their homes. Two tier pricing is not an option. All electricity will eventually have to be paid for at the same price from the first unit used, whether it be for home heating or the car.

Don't Get Excited About Nuclear Power

The world is in a tight corner and people are far too optimistic. Thinking that carbon pollution will cure itself is not scientific fact. Only a fool would hang onto the notion that nothing is wrong. The poles are thawing out and that is fact. Polar bears are dwindling in number as their traditional frozen feeding grounds get warmer. Butterflies that used to stay on in winter in southern England have moved north to colder climes. Those species that stay are getting larger.

Despite coal power stations being the main culprit more are being built to meet Mankind's increasing demand. Much is said about nuclear power stations holding the key to a "clean" future. Used uranium is going around Europe at this very moment without finding a home in any country. Where will this dangerous product be put in the future? Unless it is blasted into space toward the sun there is no where for it to go. France gets more than 80 percent of its electric power from nuclear means, but this is the country with the used uranium problem.

Even some scientists say the carbon footprint of nuclear power will be reduced to zero. This is hogwash. If you ignore nuclear waste everything looks good. Include it and it all looks very bad indeed. Nuclear power isn't cheap. Building a nuclear power plant requires long term planning. Safe guards are costly. Their useful life is also limited. Coal plants can stay in operation for much longer.

Within twenty years all 25 of China's new nuclear plants will come online. The world will be a militants' paradise with used uranium for sale on the open market. The consequences will be catastrophic. Saying there is no carbon price is absolute rubbish. If a bomb goes off there will be plenty of pollution.

Power Generation Via Hydrogen Is Not Taking Off

It is amazing how many will see something new, then run with it to the extreme saying this will change the world. This is true for virtually all non-fossil energy producing systems, but all of them have drawbacks and none have revolutionized the power sector. The two major problems have been high cost and inconstant energy production during the 24 hour period.

Scientists have worked on hydrogen systems for decades and success seems very distant. It is not being accepted for widespread use. Actually, hydrogen is a "byproduct" of energy production. When electricity is generated by any method the excess not used at a point in time is passed through water. It splits in oxygen and hydrogen via electrolysis with the fuel being stored to be used in the future. When hydrogen is recombined with oxygen, electricity is generate. Heat from the process can also be used directly for heating purposes.

As with other environmentally friendly electricity producing methods time will tell if hydrogen is accepted for general use. Perhaps hydrogen can be made in significant quantities from solar and wind generation. It could potentially make for a hybrid system producing electricity 24 hours a day. Until now, governments have been the main source of funding for hydrogen experiments. Apparently, the private sector sees little future in it. For non-fossil energy systems to flourish it is necessary for the community to work together. Unfortunately, individualism is the norm. Perhaps this is why there is very little progress.

The Danger of Nuclear Power Stations

Countries are going ahead with investment in nuclear power despite very real dangers. Similar crises to Chernobyl and Three Mile Island will definitely occur in the future with catastrophic results for resident of neighboring nations of the country experiencing the problem.

Where are they going to put the contaminated material after use? Putting it deep under landfill and into natural cavities in the earth have failed in the past. The only answer is to launch it into space on a trajectory to the sun. But what if the rocket explodes in the earth's atmosphere or crashes to earth?

Nuclear power is also very expensive. It is too high a price to pay to reduce green house gas pollution. Electricity charges are already going through the roof in Australia and the green tax hasn't even been instituted yet.

There is no way the use of uranium purchased from countries such as Australia can be policed. Once another country owns the uranium it can use it for military purposes, though all nuclear weaponry so far produced in the world have come from military dedicate nuclear facilities.

New Solar Power Station in Western Australia

Australia goes its own way in lower carbon power generation by opening a solar-diesel power station, the world's first, in Western Australia. Solar panels track the sun during the day. The station is built in a location that holds the record for the most days of maximum temperature. Use of the solar panels will lessen greenhouse gas emissions by 1119 tonnes a year.

the local Aboriginal community if fully supportive of the power plant in the Pilbara. Aboriginals named it Pippunyah, the name of the river nearby. Funding came from the Federal Government in its renewable remote power generation program via the Office of Energy in Western Australia.

It is unfortunate that solar power generation had to be combined with fossil fuel generation. Even getting natural gas there would have been better than diesel. It seems there is no perfect solution to the pollution problem. New systems only seem to meet requirements half way.

Natural Gas Must Not Be Used as a Substitute for Clean Power Generation

It is proposed that natural gas be used instead of coal for electric power generation. The national climate summit put a deadline of 2012 for this to happen with the dirtiest power station, Hazlewood. Environment Victoria took up the challenge saying that natural gas with renewable energy resources could reduce Hazlewood's pollution by 14.4 million tonnes to just 1.8. Wind generation would gradually replace natural gas.

The claim is exceedingly optimistic. Too much faith is placed in wind generation despite the fact that electricity production by this means has peaked in northern Europe and it still does not make a profit.

Beyond Zero Emissions is even more optimistic. Its plan aims to end Hazlewood's use of coal by 2013.

The future looks good for natural gas production with gas being obtained from coal seams and 20 gas power plants being planned. Natural gas is not really clean though. Indeed, leakage of methane gas occurs. Replacing coal power generation with gas as a temporary measure is a mistake. What is the point of wasting millions of dollars in investment on the premise that something better will come along?

The best way to go in the short term is to build solar thermal power sites alongside existing coal power stations. Note that solar thermal only produces electricity during the day. A final solution will undoubtedly be tidal generation because the moon continues to circle the earth making oceans rise and fall day after day.

Models Show Lasers Can Produce Energy Using Hydrogen-Boron as Fuel

Energy created by laser could be the way of the future. Researchers have used models and they show that lasers can produce "cold" energy by nuclear fusion. A new generation of fast, powerful lasers makes this possible. To achieve fusion a short, carefully controlled pulse is required. The pulse target is hydrogen and boron. Creating neutrons is not the objective because they cause radioactivity.

The Australian research is duplicating what is going on at the National Ignition Facility at the Lawrence Livermore National Laboratory in the United States, but they are using deuterium-tritium fuel.

A single laser pulse can generate 500 times more electricity than all the power stations in the US. At first the research team did not believe hydrogen-boron fuel would work. However, models indicated that it was only ten times more difficult than deuterium-tritium. For it to work the laser pulse must be clean, that is, lasting only a million, millionth of a second. Optical energy is then converted to mechanical energy.

It is not commonly known but coal power stations actually emit radioactivity - it is a problem in Germany where they are considering burying polluted material. Producing energy by laser pulsing hydrogen-boron creates less radioactivity than using deuterium-tritium. Coal generation is very dirty compared to hydrogen-boron. The waste product is helium gas. Hydrogen-boron is also plentiful. Team leader Professor Hora say it could be some time before the research becomes reality.

Hills Hoist Put to Use Again

Australians worship the Hills Hoist. Wherever one travels in this hot brown land the Aussie clothes line can be seen, with shirts and skirts attached thereto. It seems, however, that in other countries the Hills Hoist is a blot on the landscape. In the US the hoist is hardly seen at all. In the 1950s the electric dryer arrived and more recently in the 1970s regulations were brought in to prohibit the hoist on aesthetic grounds. Some argued that the humble Hills Hoist detracted from perfectly manicured backyards and could reduce home values.

The tide is turning. For people are hanging out their washing in protest. You see, electric dryers are bad for the environment. A significant amount of electricity is used by electric dryers in the US, six percent in fact. Furthermore, commercial laundry establishments including laundromats, gaols, prisons and hospitals use gas dryers. The humble clothesline could be a valuable weapon in the fight against global warming.
