Turbo the word that always came out from a teenager or street racer fan that want to modify their car to get more horsepower per cubic of fuel.They can spend a lot of money so their car can equip with turbo technology.But what is actually turbo mean for.Turbo mean for Turbocharger. The working Principal of turbocharge are turbocharger is a small radial fan pump driven by the energy of the exhaust gases of an engine. A turbocharger consists of a turbine and a compressor on a shared shaft. The turbine converts exhaust to rotational force, which is in turn used to drive the compressor. The compressor draws in ambient air and pumps it in to the intake manifold at increased pressure, resulting in a greater mass of air entering the cylinders on each intake stroke.More air mean more oxygen for combustion.So more horsepower will produce per cycle of engine.(Source from wikipedia)

International space station

When i see a documentary about building International Space Station or ISS. I realize that it not easy to build a huge superstructure that need build in hustle environment.To build ISS it need all country in this world to collaborate with one another whether have same ideology or not.The International Space Station will be symbol of peace and humanity of human kind .Beside that,by building ISS,we can have more cutting edge technology that will be applied to daily life.I hope this international project will be the milestone of human in space exploration.

Most newer production engine at nowadays already equipped with Variable Valve Timing and valve Lift using electronic Control.Like VTEC for Honda,Mivec for Mitsubishi,vvtl-i for Toyota,and CPS for Proton the national car maker.By using Variable Valve Timing and valve Lift technology,the internal combustion engine does not need use forced-induction system like turbocharge system to produce same horsepower when forced-induction system are used.The Principal of this Variable Valve Timing and Valve Lift system are using two camshaft profiles and electronically selects between the profiles.One profiles of low revolution per minute(rpm) but better fuel efficiency and another profiles for higher rpm to achieve more horsepower.When at high rpm the onboard computer will automatically change it cam profile to higher cam profile make the valve lift more so more air will get in the combustion chamber.By that more horsepower will produce.

how New technology will decreases the rate of road accident.

when i read about new safety feature on current production vehicle like anti-lock braking system(abs), traction control system (TCS), Electronic stability control (ESC),airbag and many more.i realise that this new technology can save our life when something wrong happen to us when we are driving .For example,airbag can safe us by absorb the impact between our head and the steering wheel when front crash happen.while electronic stability control or ESC will help us to stable the vehicle when we change direction at high speed such as avoid something.It work by doing automatics breaking to individual wheels using electronic system.ESC only act when it detects loss of steering control like when the vehicle is not going where the driver is steering it direction at high speed.I hope all this new technology's will decreases the rate of life loss in road accident.

global warming

Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the last century.[1][A] The Intergovernmental Panel on Climate Change (IPCC) concludes that increasing greenhouse gas concentrations resulting from human activity such as fossil fuel burning and deforestation are responsible for most of the observed temperature increase since the middle of the 20th century.

Global warming became more significant to our live today.more and more sign of global warming appear to warn us.For example the sign of global warming like the polar ice melting,increase of the sea level and more.My comment about this event is came by human activities.Since the human being start to progress to modern era or science and technology,they start to destroy the earth .we must stop this habitat.we must start to protect the earth by now not in the future.we need recycle our waste that can be use. for example paper, plastics,metal,and so on.by that we can reduce the waste that need landfill and energy that need to produce new thing from it ore.By recycle paper, we can save a lot of tree that need to cut down to produce new paper.By that more tree mean more carbon oxide can be process to oxygen and less green house gases that cause global warming.So the important massage was we must start to protect our only "home" by now not tomorrow or in future.
