What is a Hybrid car?

In Car on 22 August, 2006 at 3:00 pm

A car is considered a hybrid if it satisfy 3 conditions:

  1. Not using the main engine while idling
  2. Able to recycle the energy use for braking back into the charging of the electric motor
  3. While accelerating, the electric motor will be able to assist the main engine

The car has to satisfy all 3 conditions because only with all 3 mechanisms can the car be able to save enough petrol so as to be substantial enough to be considered as a “Green” car.  This is especially true when newer technology actually allows certain car to achieve the first condition.  This kind of car, though without any electric motor, makes use of an added Lithium-ion battery to power the car while it is idling.  This unfortunately does not translate into substantially more saving of petrol dollars.

Current hybrid cars are still making use of Nickel Metal Hydride (NiMH) batteries as there are some problems when trying to make large Lithium-ion batteries.  Large Lithium-ion batteries are prone to combustion and thus are not ideal to be placed in an automotive vehicle.  If this and other problems can be solved by the industry it will herald in a new era for hybrid or even pure electric cars.  With Lithium-ion batteries, hybrid or pure electric cars will be able to get great efficiency, acceleration and range, all at the same price or even cheaper than today’s conventional cars.

Battle of the Giants: Intel Core 2 Duo Vs AMD Athlon64 FX-62

In Electronic on 7 July, 2006 at 3:00 pm

This month will see the arrival of Intel’s latest weapon against AMD, the Core 2 Duo processor.  The battle will thus heat up and a price war will also be looming on the horizon.  This can only be good news for consumer like me.  Currently AMD is holding the crown for the fastest processor that can be use for Windows and thus the price for such a processor is also very expensive.  Its used to be that Intel is the more expensive party, but now the situation has been turn around.  When the new Core 2 Duo is out, I believe the situation will change again.  Tom’s Hardware has come out with a preview of the performance of the Core 2 Duo (codename Conroe) and it seems that the slower Core 2 Duo at 2.6 GHz can even beat the fastest FX-62 at 3.0GHz.  Yes, price war!  Let us, consumers, reap some benefit.

I can still remember the days when an Intel spoke person said that they are not afraid of AMD, this is prior to AMD launching its ever so successful Athlon.

Multi-touch technology

In Electronic on 8 February, 2006 at 9:40 am

I have come across a new touch screen technology from New York University Media Research Lab.  Its really amazing.  Zooming in and out of a picture, dragging them here and there, zooming and panning a world map in 2D or 3D, turn table and music mixer.  You can do all these with a touch screen and your hand.  Kind of remind me of the movie Minority Report, whereby Tom Cruise interact with the futuristic computer to find information.

But I still think that our “fat” finger will get in the way once the touch screen panel becomes smaller.  Thus the recent Apple’s patent filing for multipoint touch screen might be a bit of a stretch if they are going to implement it on a screen as small as the current iPod.
