Australian Wheat Yields Have Stalled

There is no doubt that the climate is changing. Usually moderate areas are becoming arid and other places are getting record rain. Countries are not prepared for this. Farmers must change to other crops to stay survive.  | __ ..There is strong evidence globally that increasing greenhouse gases are causing rises in temperature .   
The wheat yield in Australia increased 300 percent to 1990. Since that time output has been steady. Rain seems to be sufficient near the coast, but inland there is not much wet.  Government must do more to help those adapting.  | There is strong evidence globally that increasing greenhouse gases are causing rises in temperature __ .. || .. |    
   
Wheat is a staple for everyone. If the shortfall continues the price will increase. Furthermore, Australia is a major world exporter of wheat. Farmers have changed practices: this has maintained production. | weather has reduced potential crop yields __.... | not.| ....__

Not Positive Work on Coal-Fired Power Station Carbon Capture - Pollution

Coal powered power stations to lessen pollution by carbon capture - power.
For decades there has been much talk about capturing carbon from coal-fired power stations. So far projects have failed to come up with a viable solution. Coal is dirty and it remains so. Nuclear is more realistic alternative but it is dangerous.

Pollution from coal-fired power station
A new attempt is about to be made in India by Carbon Clean Solutions (CCSL). Claims are being made of capture costs as low $30.00 a tonne, half of that achieved so far in other tests. Pollution is also claimed to be reduced to zero. Such figures are obviously totally baseless.

Reduction of carbon by salt and amines to soda ash is the method to be used. Soda ash is used for fertilizer and cement. There is more than one system. The list includes solvent, membrane and negative emission.

The UK has cut funding in its research program. President Trump of the US has indicated he will expand coal power stations as there is no global warming caused by pollution - he believes. Countries are not acting in a positive manner to reduce the deleterious affect of coal.

Elecric Cars are a Mistake

Adopting battery powered cars is the worst thing societies can do. It is just a transfer from dirty oil engines to dirty oil power station. Removal of carbon at power stations is talked about a lot. However, nothing has been achieved. Experiments have largely failed.

The distance barrier is still a problem for battery cars. To go more than two hundred miles requires an enormous battery, far to heavy to put in vehicles. Price is still an issue: there is little hope of a reduction even with mass production. Weak demand continues.

Planners are saying that the lack of battery "charge" centers is the main barrier. This is only secondary. Where does the capital come from to build them? Battery swap stations were established by the Electric Light Company to service a fleet of electric trucks a century ago. Buses in China get new batteries en route. The trucks disappeared and Chinese buses are government run.

Changing to a recharged battery is not cost effective. If you have to do this you may as well keep the petrol car. A charge-up at home is the only way to go. Long distance truckers will never adopt battery power. There is little torque in the powertrain, certainly not enough to transport heavy goods.

New iHerd App Helps Australian Farmers

If labor costs are high in a country it is necessary to turn to technology to efficiently do the job. Australian farmers have been world leaders in applying technology to tasks. Thus, there is an increasing demand for skilled labor on farms. This obviously goes against tradition.

A new app for farmers has been released called iHerd. The app keeps an eye on cattle as they move around. Tracking is much easier. Gathering of cattle into yards is reduced. Cattle have monitoring tabs fitted to them. As they come in to drink, tags are identified and weight is taken. Animals of a certain weight can then be selected out.

An important benefit is that the knowledge has improved production of healthy cattle. Of course, farmers themselves have to learn new skills. This they are doing very well indeed. New technology is being adopted and applied rapidly.

A more technologically based farming sector could attract skilled young people back to the land. This is not a goal, though it could happen. They will have accept losing some of the benefits of city life and be more hardier in there nature.

Australia Breaks Supercritical Steam Record to Replace Coal

Australia has made a new world record in "supercritical" steam. This involves the use of solar panels to generate heat that boils water and generates steam. The steam could be used instead of coal in power plants.

Pressure reached 3,400 psi at a heat of 1,058°F. This is peak performance "stuff". It rivals coal in its efficiency. The first time a non-carbon source has at least equalled the efficiency of coal.

Six hundred mirrors (heliostats) were used and their beams were directed at two towers housing solar receivers and turbines. In the future power generation could be virtually free from the sun during daylight hours.

This technology is new and supersedes older "subcritical" steam production. More work has to be done but there is no doubt power generation will eventually not need coal. It is not good news for Australian exports. It is good for the world though.

Individual Solar Power Systems Will Replace Power Stations

So the energy companies have Australians by the "..." in regard to charging what they like for electricity? This may be fact now but in a few years the tables will be turned. By 2018 the cost of off-grid power will be on par with charges by electricity producers and distributors.

Battery storage from solar generators will be adopted by people living in the bush. Some are so far away from the main grid that they do not have an electricity connection at all. The methods they find cost effective will be copied by city people. There are varied methods and combinations so choices can be made.

Rural towns could pool resources and create a generating system for the whole town. They will have to solve the problem of the unevenness of power flow to households which results in failing TVs, fridges and washing machines first though.

Because of costs saved from higher scale production those in higher populated centers could set up non-carbon electricity system cheaper, so hobbyists and experimenters could be first to go off-grid.

With this trend, the part-privatization of electricity by allowing another level of distributors into the market will prove to be a problem. These distributors will face falling profits and cost cutting could begin. The average consumer could face lower charges.

Non-carbon energy methods no longer need government subsidies. They are now cost effective. Indeed, set up costs are falling very rapidly. Increases in recent electricity charges due to generating companies repairing old infrastructure could be money wasted. The new electricity poles could be left standing with no active wiring in the very near future.

Investment in Clean Energy Production Predicted to Rise

It is predicted that the use of solar and wind power will rapidly increase as costs falls. There has been an improvement in the efficiency of wind turbines. Solar panels also put out more power at a lower cost.

Australians have strongly adopted solar power while governments offer high payments for electricity going back into the system. Making an end date of 2026 of such overpayment was a silly idea. It is too far ahead for future governments to guarantee this "lopsided" subsidy that only helps the wealthy. The financial burden has been pushed onto the elderly.

Solar power has hidden costs. Power surges burn out televisions and computers. New ones must be purchased. Many consumers are saying someone has to fix this. Considering solar power generation will fluctuate throughout the day with this is near impossible.

Frank Calabria, CEO of Origin Energy, favors the elimination of all subsidies on clean energy. This indicates a probable back down considering Origin is the largest investor in wind farms. Coal remains the cheapest form of power production in Australia. This economic advantage will continue. Whether new calls for nuclear power are supported is unknown are present.

Remote Sensing Reduces Farm Costs

Telemetry and remote sensing significantly cuts labor costs on agricultural properties. Water supplies for stock are being monitored remotely with water levels being relayed via radio signals back to the homestead.

Besides water levels at bores, animal weight can also be remotely monitored, but more work is needed on this. Water level, however, is by far the most important part of work on cattle stations. At Napperby station near Alice Springs the bore runs for 500km. This used to be checked three times a week. Now a physical check is done only once a week. The Fuel cost for motor vehicles is significantly reduced.

Cattle are more easily monitored because they congregate as a group at water bores. Remote drafting and weighing of cattle is being perfected and this will contribute greatly to cutting labor costs.

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.
