For hundreds of years, coal and fuel oil have been singing the Kingdom “hero.” Imagine the old coal and oil “ancestor” Since ancient times plants are then planted energy crops can do? The same as harvesting crops to “harvest” the oil it? This will be the 21st century, a new issue of common concern.

Many countries have begun “petroleum plant” and planting of, and through introduction, cultivation, and establish a new energy base of an “oil (more…)

Is the second generation of plutonium fast breeder reactor fuel.

The second generation of reactors is a French design called the second generation of fast breeder reactors, since they gave it a nice name “Phoenix” reactor to plutonium as nuclear fuel, no moderator, and only liquid sodium as coolant (heat carrier agent). This type of breeder reactor has reached the commercialization stage. France has built an ultra-”Phoenix” type breeder reactor, used for power generation, power is 1.3 million kilowatts. France in the second-generation commercial fast breeder reactor, the leader in 10 years than any other country. Fast (more…)

(A), market status

In 2004 the price of notebook computers can be said to record lows, and now no one says no, low cost notebook computer line lies. Who want to purchase the 2005 budget but not too well-off friends, may be most concerned about is the 2005 notebook to what extent can be cheaper.

Said to have been a domestic brand notebooks in 2005 to do 3999 yuan, but off in mid-2004 when it was ahead of evolve into a living reality. One wonders how such a cheap laptop now, and desktop fast running out, in the end when a tall cheap to you? To answer that question, we must (more…)

01) defragmenting the hard disk “failure”

Recently the use of Windows native defrag functions encounter a strange question, select the. Set by “analysis” button, it says “need to Defrag the hard disk” and then click the “order”, too – after the prompt “order complete”, but distribution of data on the hard disk does not happen any | any change (still very messy ), I cup defrag simply no doubt play a role, how is this going on, hard drive broken? Are there any other way to solve (more…)

Chemical power source is a chemical energy directly into electrical energy. In principle, all redox reactions can be designed into the chemical supply, but for various reasons, the real value of practical application of the chemical power supply a few. A manganese zinc batteries, lead acid battery, a nickel-cadmium batteries, a silver zinc batteries, lithium battery, a nickel-hydrogen batteries, fuel cells and lithium ion batteries is the (more…)

Batteries battery memory effect is reversible failure, that battery failure can be repeated after the recovery performance. Cells undergo a specific long-cycle work, automatically maintaining a specific memory performance. Bag battery no memory effect, sintering batteries have memory effect. If the battery after long shallow discharge cycles, and then to deep discharge, which demonstrates significant capacity loss or (more…)

Select the shell material, first of all to meet the product requirements for the prerequisite in achieving performance targets, should be further excessive demands, to increase economic efficiency. And then to consider cost, processing, raw material sources, etc., in the choice of materials, should be according to local conditions, not to detour. Also, pay attention to the development and use of new (more…)

Dye-sensitized solar cells (DSSC) the most attractive features is its cheap raw materials and simple production process and a stable performance. Its main semiconductor material is nano-Ti02. Nano-TiO2 with a rich content, low cost, non-toxic, stable performance and good (more…)

Practical fuel cells are generating the biggest obstacle to cost. Cost of power generation equipment at the time mainly by the development costs (mainly stack of material and manufacturing costs) and run-time fuel consumption, maintenance costs, battery-for-use fees, operating costs (long-term costs) to decide. Make the (more…)
