Technological metals – Term introduced in 2007

Technological metals – A concept that is relatively new, in contrast to the actual use of metals in science and industry. The date in 2007 was introduced by American chemist and physicist Jack Lifton. Since then, it is often used in industry. Generally, you can say that the tech. metals are basically precious metals and those that are necessary for the production of hi-tech devices and engineering systems. This category includes:

  • commercial production of miniature electronic devices
  • advanced military systems
  • generating electricity using alternative sources, for example solar panels or wind turbines
  • electricity storage using batteries and cells.

There are of course a lot of other uses of these elements. Almost all technological metals are a by-product of the treatment of basic metals (except for precious and lithium).

Flying police – Projects police cars

Flying police – Projects police cars entered the competition, which was held at the Motor Show in LA, consist of:

  • BMW Group Designworks USA – E-Patrol – Double cruiser equipped with 3 small unmanned drones. EPatrol will recover electricity from sheet by hot blazing sun tarmac, the car will be prosecuted and detained electromagnetic pulse.
  • General Motors – Volt Squad a 3 electric vehicles: Observeused for observation and control. Pursue to chase, and Engage the transportation of detainees delinquents.
  • Subaru – SHARC (Subaru Highway Automated Response Concept) which won the competition for LA Design Challenge – highway patrol vehicle itself has some interesting technical solutions:

thin organic foam-filled tires instead of air

the suspension is, however, electro-mechanical, with a special material IPMC (Ionic Polymer Metal Composite) enabling, depending on the applied voltage embracing different shapes

– with electrical energy wheels can also be deflected vertically.

Energy from sugar – Bio-Battery

Energy from sugar – Bio-Battery

Energy from sugar – A team of researchers from the Technical University of Virginia (the so-called. Virginia Tech) was inspired by nature and last year presented a draft of a battery that uses sugar to produce electricity.

The energy density of sugar is much higher than conventional lithium-ion batteries,

He pointed out one of the advantages of the invention, research manager Y.H. Percival Zhang, an engineer biological systems at Virginia Tech. Bio battery offers an energy density of about 596 Ah / kg (ampere-hours per kilogram), while the typical lithium-ion battery has a density of only 42 Ah / kg.

Church tower protruding from water

Church tower protruding from water – The Lake Reschensee in South Tyrol (Italy) waiting an unusual sight: a protruding from the water Church tower. Only that was from the village of Alt-Graun. In the 50’s of the last century energy company decided to create there a reservoir for electricity and water. AltGraun residents were displaced, and the valley around the village – was poured. Today, almost nothing after it has been – apart from protruding from the water tower of the ancient parish church of St. Catherine.

Conductive metals – Standard on properties of silver

Conductive metals – Standard on properties of silver

Conductive metals – Standard on properties of silver – Conductor causes little resistance to the flow of electric current or heat, which means that the load can move freely. Electrically conductive metals, usually also conduct heat. In selecting the most-conductor metal is silver, copper and gold. Standard conductivity of metals is based on the properties of silver, which is the best conductor of all pure metals. On a scale from 0 to 100, where 100 is the best conductivity, silver received 100. On the other hand, gold considered to be an excellent conductor, received only 76 points.
