Waste Heat Power Could Double Battery Life on Computer

When we utilize any gadget or means of comfort we know that these devices consume energy.But the energy is not utilized by devices.Some of the energy is lost in the form of friction or heat.For example when we are exploiting the power of computer battery processor chips,car engines or electric power plants there is a necessity of getting rid of excess heat otherwise the equipments will not perform at their optimal level.Now researchers are thinking about using this waste energy.Peter Hagelstein is the co-writer of this concept and an associate professor of electrical engineering at MIT.His paper was published in the November 2009 issue of the Journal of Applied Physics.

They are gunning for a realistic technology that could come to achieving the theoretical limits for the efficiency of such conversion.Theory postulates that such energy conversion can never go over a precise value called the Carnot Limit.Carnot Limit was established in 19th-century.It is a formula for determining the utmost efficiency that any machine can achieve in converting heat into work.But the fact is in practice we have only achieved about one-tenth of that limit.Hagelstein working in close association with Yan Kucherov carried out experiments by going for a different technology.They have achieved the enviable efficiency as high as 40 percent of the Carnot Limit.Moreover,their statistics exhibit that this new kind of system could ultimately reach as much as 90 percent of that ceiling.

If this wasted energy is cleverly harnessed we might double the use of cell phones talk time without plugging them again and again for recharging.The same could be the case with our laptops;we don't have to recharge them frequently and their wear and tear could be reduced too. The overworked and overloaded poor backup power battery plants can shell out more power if their wasted heat energy can be utilized.Hagelstein is of the view that current solid-state devices that utilize excessive heat and convert it into electricity are not very efficient.He is working with his graduate student Dennis Wu as part of his doctoral thesis to find out a practically dependable heat energy converter that doesn't carry forward its predecessor's disadvantages.

Hagelstein,Wu and others didn't try to improve upon existing devices.They started afresh without any past baggage.They make use of a very simple system in which power was generated by a single quantum-dot device.That device is a type of semiconductor in which the electrons and holes are very securely restricted in all three dimensions.So they tried to understand all the features of the device.This helped them in understanding better all the aspect of such machine.Hagelstein says that he doesn't merely want to convert heat into energy but he wants to achieve this by getting lots of energy in return.He also admits that current technology is available to harness heat power,but with a catch.It is known as high-throughput power.It converts heat from a less efficient system and you get more energy.But this is larger and more expensive system.According to Hagelstein "It's a tradeoff.

You either get high efficiency or high throughput."But the team found that using their new system,it would be possible to get both at once.Hagelstein and his team studied a recent paper published by MIT professor Gang Chen carefully.They talked about lessening the gaps between hot surface and the conversion device.They suggested this arrangement as very crucial for improving the output.Gang Chen claimed that heat transfer could take place between very closely spaced surfaces at a rate that is orders of magnitude higher than predicted by theory.The new report admits going a step further that portable solar power heat can not only be transferred,but converted into electricity so that it can be harnessed.

At the same time Hagelstein's work would give the required push and an additional tenfold or greater improvement is possible.DiMatteo presents his stats and says that worldwide,when we consume fuel or a powerhouse generates electricity nearly 60 percent of all the energy is wasted.This waste is generally in the form of heat.60% is substantial amount.DiMatteo is now hopeful that this technology could "make it possible to reclaim a significant fraction of that wasted energy."Hagelstein is of the opinion,"There's a gold mine in waste heat,if you could convert it.A lot of heat is generated to go places,and a lot is lost.If you could recover that,your transportation technology is going to work better."

Do You Know How to Check Laptop Battery Life?

The battery life of a laptop is an obviously important part of the laptop's overall performance.If you run out of battery life you can't do anything-so try not to run out,right?While that rule seems simple enough,it isn't always easy to follow.Laptop manufacturers have a tendency to overstate laptop battery life,and sometimes by no small margin.A manufacturer who claims ten hours of battery life rarely confesses that the stated battery life can only be achieved if you leave the laptop running at idle with the display a minimum brightness and WiFi off.

One of the worst things that can happen while working on a laptop is to have your battery die while you are in the middle of an important project.To avoid this,it's good to know how much life your computer battery has left in it.Most laptop computers offer a couple of ways to do this,and there are several free downloads that will put a large battery-life monitor on your screen,meaning you'll never be caught with a dead battery unexpectedly again.

Look in your computer's system tray,which is at the right side of your taskbar near the clock.You should see a battery icon.If it doesn't show up automatically,click the arrow on the left side of the system tray,which will expand the tray and show all icons.Place your mouse over the battery icon,but don't click on it.The icon will show roughly how much life is in the battery.Hovering your mouse over it will pop up a label showing exactly how much time remains before you run out of power and what percentage of the battery remains charged.

Plug in your AC adapter if the battery needs to be charged.The status in the system tray will show that the computer is now running on AC power, and the battery is charging.Many sources recommend letting a battery fully drain,so as not to shorten its "memory."However with lithium battery,the most common type of battery in modern laptops,this is not the case.If a computer battery is discharged past the critical 3% level,the battery may not be able to be recharged again.This effectively kills the battery.A laptop battery needs a small amount of power in it in order for it send communication back and forth with the laptop to recharge the battery.

If you're interested in how your laptop battery might hold up during less intense use,however,you can use the included Reader's Test benchmark.This can be accessed by clicking on the Options button and then changing the Benchmark Mode to Reader's Test.Once that's done, click on the Load Text button at the bottom of the window and select a text file.The Reader's Test,once activated,will open the text file and automatically scroll through the file time and time again until your laptop's battery gives out.

A battery in a "weakened state" is a good candidate for this fatal mistake.When batteries are brand new or inactive for more than 2 months,they are in a weakened state and must be conditioned with 4-5 partial discharge and recharge cycles to bring them up to full capacity again.A new battery may cause the backup power battery icon on your computer to indicate you have a low battery condition.We recommend that you let the battery charge overnight in your notebook computer.It may be necessary to remove and replace the battery and restart your computer with the battery installed in order for the computer's start up sequence to properly recognize your new battery.Rechargeable batteries will self discharge when not in use over a period of time.This might seem obvious but don't burn,disassemble,mutilate or short circuit batteries.
