Future production woes in tehnology

< >The report by Prof.Thomas Gredel points to the scarcity of rare

earth materials.He claims that out of the 62 minerals 12 had no

alternatives when the mines will go empty.He further states that the

rest have alternatives but cannot work at their best with existing

technologies.< >China is the mining giant of rare earth materials.It

controls 80percent of the world's production.However it has come under

criticism in 2010 for its restriction for exportation of this precious

resource.The consequences are skyrocketing of prices upto five times

the normal whereas local companies in China were offered low costs.<

>Prof.Gredel said,''As weath and production increases worldwide

scientists will be challenged to maintain production quality by

designing new and better materials but doing so under potential

constraints in resource availability''.< >This attests to the fact the

precious minerals could face distinction in the future as a result of

high demand for gadgets amongst the population which increases the

production rate.< >

Amazing lego air-powered car

Air powered cars have once been my idea when I worked on a balloon powered car project.I presented it on science congress contest upto the District level.It was not a welcoming idea since my concept was not well developed.It only featured a ballon for propulsion. The lego air powered car invention is definitely a breakthrough for a group funded project.It is said to be built with 500,000 legos except for the tyres.The inventor claims that he was neither a technology nor a lego enthusiast!!! Click image to purchase acer chromebook. The group was funded by 40 donors through a twitter request.It is said to have costed more money than the initial budget.The automobile has been test driven and runs upto a maximum speed of 18mph/40kmh. Engine consists of pistons to compress air which maybe, provided the desirable kinetic energy(energy in motion).This energy propels the car forward.Ho...

Characteristics that make a good online IT entrepreneur

An online IT business is definitely an envy to many to many entrepreneurs. It is easy to setup and costs less. Many people often succeed in this venture. However, a person needs to have important attributes and traits during the initial years of the business.

Without patience, you won't be able to keep the business running. Most businesses often start slowly and require lots of patience before making profits. Sometimes the rewards can be disappointing but you should know that a business is a risk an...

Producing electricity from roads

A mexican scientist Marcias Hernandez has developed a system through which can help generate electricity using automobiles. The concept he developed is not new because other methods exists but is cheaper and less complicated. Other conventional methods have been using pizoelectric effect to generate electrity. Energy is driven from the stress exerted by moving vehicles. The energy is then coverted into electricity and stored in batteries by the roadside. Marcias new invention involves the use of trumps, which moving vehicles exert pressure when running over a polymer ramp. Air is then forced at high pressure into a storage tank via hose pipes where it is stored and released. When it accumulates, it drives a turbine built underground. The turbine will then use this kinetic energy to be converted into electric energy by the generators. Israel has already constructed such a road system that is able to generate electricity.
