Efficient Solar Panel Paint Developed

There is about to be a revolution and it is not wearable technology. A spray on paint to quickly make solar panels has been perfected. The paint's main ingredient is perovskite - a calcium titanium oxide mineral. Furthermore, it costs very little.

Soon cheaper solar panels will be flooding out of factory production lines. They will be used everywhere - even on wearables! Perovskite is twice as effective as current spray-on solar collectors.

The environment will be "covered all over" with this new effective paint. Every surface facing upward whether on something mobile or static will have this coating.

Dramatic change will seen on buildings. Indeed, it will be available in many colors and will become an important part of the designed environment. Battery powered cars will have the paint completely covering the vehicle. It will become as common as ordinary paint is today.

Aluminium Once Cost More Than Gold

The metal that could only be made in large quantities when electricity became widely available was once valued more than gold. Eight per cent of the Earth's crust is made up of mineral aluminium such as potassium aluminium sulfate. This was used in times past for fire-proofing and tanning of leather.

Today, it is in baking powder and aftershave. The refinement into aluminum metal wasn't theorized until the late 19th century. Hans christian Oersted created the first sample of the metal in 1825. It was highly contaminated. Sodium was then used by Henri Saint-Claire Deville to produce more. In 1845 scientists found it to be extremely light in weight. By 1855 small ingots were made and its price skyrocketed. Indeed, Napoleon 111 valued his aluminium cutlery more the the gold alternative.

Electrolysis was the major breakthrough in the production of large quantities of aluminium. Bauxite was identified as the best and plentiful source material. The price fell 80 per cent almost immediately as it became the cheapest metal available. The price fall is notable: $US1,200 a kilo in 1852 to $US1.00 in the 20th century for the same amount.

Eucalytus Trees Store Gold in Their Leaves

A way of detecting gold deposits beneath the ground has been right in front of our eyes for years. Eucalyptus trees take up gold particles into their leaves. X-ray imaging could replace test drilling.

Eucalyptus roots go down a very long way in search of water. Some sinker roots reach 40 meters below the surface. If there is gold in the ground it is concentrated in the leaves. It is pushed to extremities of the tree because gold is toxic.

Research has proven the theory. Trees above gold deposits store gold, but in gold-free areas there is no stored gold. It is place specific as well: the amount of gold particles varies with the level of gold deposits in the ground.

There is no threat to the trees as the amount of stored gold is minuscule. All types of plants store minerals besides eucalyptus. However, the overwhelming number of plant species in Australia are eucalyptus.

It is no longer necessary to drill in difficult, rocky places. Taking a few leaves for analysis does not damage the trees. This will make the search for gold much easier and cheaper.

Revolutionary Mineral Drill Rig Announced

Drilling techniques in industry have not changed for decades. Oil rigs are built in he same old way. Now something has come along that will improve drilling enormously. The Deep Exploration Technologies Cooperative Research Centre based in Adelaide has announced a new type of drill. It is constructed with coiled tubing.

Costs will fall dramatically as drilling is faster.  Australia's mines are mostly over 30 years old. New mines have to be established. We can only rely on the old mines for another 20 years.

No longer is it necessary to keep stopping to add a new drilling section. The new drill is a continuous coil of tubing. Being smaller and lighter transportation is easy. The motor is at the bottom of the shaft, not at the top. The tubing no longer twists during drilling. Any twisting will occur in the other direction as the motor pulls the tubing around.

Less drilling power is needed as the tubing is being pulled around in already drilled space. A lot of torque was lost with the old system as the engine had to force the whole length of the drill around. Drilling will continue with fewer drill breakages. Thus, downtime will be reduced.

Australian Retail Problems Not Caused by the Mineral Sector

There is clearly something wrong with the Australian economy. We seem to in the same position of Indonesia several decades ago when it had oil and the high price was pushing up the value of the currency. A high currency makes it difficult for those producing "non-boom" products to export. That is why the US is printing more dollars to weaken the currency, improve the economy and create more jobs. Nothing much is happening for it though because the US dollar is the major international currency as gold used to be.

Just why Australian shopkeepers are crying fowl is more difficult to understand. A strong currency means imports are cheaper. Australians are very import dependent in their spending habits and buying cheap imports is what they like to do. They buy such imports over more expensive Australian made products, but this shouldn't hurt the bottom line of retailers.

They claim Australians are spending less. Though figures show this to be the case, spending is not that easy to understand. If people save, the banks have more money to lend out to business and those who want to go into debt. However, due to the financial crisis Australian banks have tightened up on lending criteria. They will no longer lend to those with no offsetting assets. In other words, banks are withholding money. This money is not active within Australia. It may be invested overseas by banks.

The retail sector is wrong to blame exporters of minerals, the economy in general or interest rates. Obviously, the cause of reduced spending is the behavior of banks. Government could force the hand of banks. It will not do this as politicians fear a bank crisis occurring here in Australia. Some European countries were devastated by the global banking crisis. Their governments lost billions in propping up banks by giving them money that borrowers could not pay back. It was taxpayers money they were "giving" away.
