going green: inventions to support sustainable energy systems in computing - battery energy storage system

Demand for green computer technology
The green invention in computer technology has been widely concerned, in order to establish a sustainable energy system in the computer,driven economy.
Energy efficiency is considered to be the most promising carbon dioxide reduction solution to mitigate the effects of global warming.
In fact, the challenge for scientists and innovators is to meet 100%-renewable-energy-by-2030-
According to a study published in the Journal of energy policy, the goal is.
The strategy to achieve this is not just to build turbines and panels to take advantage of wind, solar and water resources.
This is also to create and develop systems for sustainable energy use to narrow the gap between supply and demand.
According to energy policy research, there are its own challenges in building renewable energy systems.
In order to provide stability and consistency in energy supply, these projects also require the use of rare earth materials.
In order to overcome this obstacle, a campaign to support sustainable energy use has now been launched, as it is touted as key to achieving the global goal of completely escaping dependence on fossil fuels.
Based on this, we show the latest progress
The green invention and innovation of computers, because the demand for green computer technology stems from the fact that people from all over the world are gathered together through computing to become a global community.

Younicos-cordless mobile energy storage unit Wikipedia Yill, which powers modern workstations, has received a lot of the latest innovations from Younicos AG, whose mission statement says, "Let the fossils rest in peace.
"In line with the company's global vision to produce energy and electricity without CO2 emissions, Younicos and its 40 employees put forward Yill.
One of the main problems with the use of renewable energy by computers is the fluctuation trend of solar and wind energy.
Now, Yill solves the problem by providing an energy storage unit that can store electricity for two to three days through a lithium titanium battery. The lithium-
Titanium batteries are considered a safer, faster and more durable alternative to lithium
Ion technology has proved that it has a tendency to ignite if certain conditions are met. As a titanium-
The enhanced lithium battery reduces the internal resistance and reduces the resistance, meaning that the battery power is reduced as the heat increases.
This allows more energy to be retained and stored.
Unikos made titanium.
By developing Yill, lithium technology is more useful as it can provide modern workstations with power up to 300 watts.
The best thing is that if you get power from the grid, it allows the integration of renewable energy to offset some of the power needs of the grid.
Either way, you can store your energy through a renewable energy charging station or simply plug it into any traditional outlet to quickly
Charge the battery
Cordless Office-
On the device side, Yill offers additional benefits that allow you to set up office workstations in a layout that does not need to fit the socket placement.
It has enough mobility and flexibility to be used where power is needed.

Core voltage regulator (MCVR)
By Wonyoung Kim in Washington, D. C.
DC converter chip: possible solution to reduce heat output of laptop processorchip multi-
Core voltage regulator to reduce power demand for smaller-Size, but more
The task assignment device because it is designed to match the power supply to the demand.
This provides a better alternative for modern processing chips,-
All application processors can be started even if only one application processor is used.
This is considered one of many reasons.
After four hours of use, charge the mobile device.
Kim described MCVR as "like turning off the lights when leaving home" because regulators will be fine --
Adjust the power by releasing energy only to the currently used processor;
All other application processors that are not in use will not be able to receive power.
This indicates energy saving and longer battery life. Image source: Wonyoung Kim from the School of Engineering and Applied Sciences, Harvard University. Please go to the next page to learn more about MCVR and other ongoing

Basically, on-
The chip design manages not only the power of the processor, but also the power of each individual core on the chip.
Please check the image on the left side as it illustrates how the voltage regulator is integrated into each IC chip.
As Kim explained, "the short distance the signal has to move between the voltage regulator and the core allows for rapid power expansion --
In tens of seconds, not tens of seconds.
Further improve efficiency.
"Harvard graduate students estimate that the mobile phone market will initially be the biggest demand.
He also expects that MCVR has the potential to reduce the heat output of the laptop processor and reduce the cost of power supply
Increase servers while meeting speed and capacity requirements.
Kim's overall assessment is that integrating MCVR into the chip will increase manufacturing costs by 10%, but potential power savings will reach 20% or more.

The Electrical Engineering Department developed the first millimeter-
Complete the scale of the computing system.
It is designed to provide medical applications in the form of an implant eye pressure meter for glaucoma patients.
Prototype methods February 20 last year November of a small bag about cubic mm;
The entire computing system is composed of an ultra-low
Power Microprocessor, pressure sensor, thin film battery, memory, wireless radio with antenna, external devices and solar cells that can transmit data to the vicinity of the eye.
In fact, the microprocessor used for the intraocular pressure meter is the third-

Super Mode function allowed
Low power consumption.
As a medical device for the treatment of glaucoma patients, the system wakes up every 15 minutes, makes measurements and stores medical information for a week.
It consumes only 5 on average.
3 nano Watt, can be fast-charged with 1.
Exposed to the sun for 5 hours. For indoor-
Light charging, it takes about ten hours of exposure to keep the battery charged.
Researchers at the University are committed to developing a complete computing system that uses low-power components suitable for chips to collect, store and transmit data that they foresee possible applications.
However, the device is expected to be available in a few years, as researchers at the University of Michigan are still trying to equip it with a small radio that can talk to other devices.
This function will enhance its ability to continue to develop.
Because it will enable the system to network with other wireless sensors.

Another team of researchers from the University of Michigan's Department of Engineering and Computer Science has developed the first integrated antenna, which makes the radio on the chip work without external tuning.
Once these antennas are deployed as part of the network, they will automatically be aligned at the same frequency.
In order to match the power capacity of the millimeter level, the researchers are still studying the power consumption of the radio. Scale battery.
Because these networks can be used for other purposes such as tracking pollution, monitoring structural integrity, performing monitoring, or making any object almost observable, in order to bring this green computer technology to the market, research scientists are looking for partners to commercialize.
Other things worth noting
Green Innovations in sustainable energy use review most of the time in the past
The green invention mentioned above, according to bells's law, we perceive the future of the computer industry as scientists at the University of Michigan say: "There is a new and smaller category, there are cheaper computers about every decade.
For each new category, the volume is reduced by two orders of magnitude and the number of systems per capita is increased ".
