The advantages of a laptop and a desktop now come together as cabtop, thanks to Bhargavi, a house wife from Hyderabad who came to Bangalore, the IT, to materialise the idea. Though Bhargavi completed only her PU, she wanted to do something more.
The TEPP (Technophiles Promotion Programme) and DSIR (Department of Science and Industrial Research) Govt of India, helped her financially to prepare a model of cabtop. The idea of cabtop was started with a simple question — why can’t a machine incorporate both the features of a PC and a laptop.
The cabtop can be carried anywhere like laptops, but in a bigger suitcase. Unlike the desktop, it has only one cable. All the hardware components are behind the monitor and the SMPS (system of power supply) and DVD drives are at the base. It can work separately as a TV and a computer.
It can also turn on the TV and play DVD without turning on the CPU despite having only one power input. “The DVD player gets power supply from the same SMPS as the monitor. “Also there’s an integrated TV tuner card to watch TV. The cabtop has built-in speakers too,” says Bhargavi. With a 2GB RAM and a 320GB hard drive, the cabtop weights about 10 kilogrammes.
The important feature according to Bhargavi is that it does not require too many wire connections as a desktop. The configuration of the cabtop is as per users choice and it can be upgraded as required. Bhargavi has designed cabtops that come in 17, 19 and 21 inches. But here is the interesting news. All existing desktops with LCD ot CST monitors can be converted into cabtops.
The cabtop has been certified by the CMERC (Central Mechanical Engineering Institute), Durgapur, a lab run by the Indian government. “My husband has been a big support,” says Bhargavi. And to this her husband Ranga Reddysays, “Bhargavi’s goal was to introduce something new to the world instead of sitting idle at home’’.
The last time aggregate power usage of all servers in the U.S. was studied was five years ago, so it's difficult to benchmark the overall power usage of set-top boxes. But in 2006, a government study put total power usage of all servers in the U.S. at about 24 billion kWh.
Davidson supplied some estimates on power usage for servers, desktops and laptops to make a comparison.
Newer, two-socket x86 servers with up to eight core chips will run at rest somewhere between 150 to 200 watts. At full utilization, this energy usage can double to as much as 400 watts.
In terms of annual energy usage, a two-socket server may use approximately 1,314 kWh a year (which is simply just powering it on) to about 2,600 kWh per year.
Other Business News:
Allowing for variations in workload demand, the average annual power use for a two-socket server is around 1,800 to 1,900 kWh annually.
Servers are expected to run 24x7, which isn't necessarily true for most desktops and laptops. But if these systems did run continuously, here's how much power they will take up.
Desktops use between 45 watts and 90 watts, so if they ran 24x7 they would use between 394 kWh annually and 788 kWh annually.
A laptop running between 30 watts and 75 watts will use between 262 kWh annually and 657 kWh annually.
Davidson said power utilization continues to improve with new generations of semiconductors, which deploy technologies such as speed step to change the chip's clock rate dynamically to reduce power usage.
