One of the biggest problem in electricity is the peak load. The grid has to meet all the demand every time and needs to be ready for that. So the difference between peak demand and normal time there are lots of power plants that are resting. Besides If you shave even a small amount from peak demand and add it other times of the day it would same millions of dollars to government as the highest bidder who is helping to meeting highest demand on a certain time is the one who determines the cost of electricity to all of the power generators. This emphasizes the importance of storage.
Technology Article Summary
In this article a startup called Axiom Energy claims to find a solution for Supermarkets for the peak hour. Company sells technology that plugs into super market refrigeration units and uses tanks of frozen salt water as a way to store energy and lower supermarket energy bills.
During peak times this supermarkets shift to use this technology, frozen salt water tanks, to keep cool the refrigerators and at nigh when the demand and electricity prices are low they can freeze the tanks with electricity. They called it as Refrigeration Battery. It is basically using thermal energy.
First supermarkets later it can be various places like data centers, cold storage units etc.
But on the big picture as it supports shaving on peak demand every tax payer would benefit.
Growing cotton is water intensive process and growing appetite for consumption with fashion leads sustainability problems or we should focus on recycling and efficiency. We should start focusing on sustainable fashion which these two entrepreneurs do. Besides it seems as good as new! 🙂
Technology Article Summary
They focused on large scale factories which usually trashes %10-%15 and they break down that fabric to fibers once again. By doing so they eliminated wasteful step in manufacturing clothes which is dying, as the textile had already been dyed. They claim that this can save 2700 liters of water which would be likely contaminated with chemical as not all of the dyers are not non-toxic and consequently that waste water mixes with local water sources such as Tirupur River
Pesola says that 95 percent of textile fibers can be recycled, “Not only can it be recycled,” he explains “but it’s actually cheaper, if we work in volume, because we don’t have to go through the dying process.” The aim of the new unit in India is mass production from recycled materials. Besides by repurposing material and sewing it in proximity, it will lower the carbon footprint, cost and make it easier to manage.
Consumers, Humankind in general
Its Already, has developed an annual turnover of 1 million euros. “The first two years has been more about R&D and setting up the production unit,” Bengs indicates. But now with the plant scheduled to be complete by 2017, they focused on pushing sales with a team of 10 in Helsinki, 5 in Mumbai, and 200 in Tamil Nadu.
I think it could be evolved movement of awareness in fashion after Toms Shoes. It definitely needs celebrity attention in USA tho. 🙂

We build our own controls and sensors and write our own code which sits in what we call the ‘phibox’ components, like the solar panel, battery management, lighting systems, water meter, self-cleaning filters are controlled through the box,” inventor says.
It depends on who is investing and where it is installed.
If it’s installed on residential. Residents are stakeholders
If it’s installed on parks, Tax payers and citizens are stakeholders.
It’s been installed in clusters of 10 pieces. Each merges into a single water tank. It pays itself in 4 years.
It can be installed in parks to feed water system and also it can be installed in residential to feed residents water demand.
Asphalt, also known as bitumen, is a sticky, black and highly viscous liquid or semi-solid form of petroleum. And petroleum is not sustainable product so for bio alternative researchers from North Carolina A&T State University have developed a process that uses pig manure as a low-cost replacement for petroleum in the production of road asphalt.
2-Technology Article Summary
In searching for bio alternatives, A&T State University researchers discovered that swine waste is especially rich in oils very similar to petroleum, at a grade too low to make gasoline but suited for asphalt.
With the funding from the National Science Foundation, the group developed a process that turns the waste into a black crude and it is much cheaper and greener than black crude.
It is without odor and is already started testing to see how would it be in real life including a simulation of truck traffic making 20,000 passes over it. The tests have so far been successful, passing Department of Transportation specifications, which led the group to form the company Bio-Adhesives to scale up their research.
Besides it is a win-win solution either for farmers and construction industry Asphalt made from pig manure could alleviate what’s become a huge environmental issue – effluence from factory farm feedlots – especially in large swine-producing states like North Carolina.
Tax payers, Farmers, Construction Industry,
As it already passed tests and Department of transportation specifications, Deployment could be start from North Caroline first as pilot region as it is a large swine-producing state and later could spread.
This set of devices solely don’t solve any problem but it enables us to solve your everyday life problems and the usage way is infinite, it basically enables anything to become a smart device and thanks to its user-friendly application you don’t even have to know anything about programming. It is up to you what kind of a sustainability problem you want to solve with this. You may put it in your bathroom for automatic lighting thus you could save electric, you may use it on automation watering for your plants thus, you may save water furthermore you may program as water usage according to humidity with if function. Rest is up to your imagination.
By 2050 it is expected that worlds population will exceed 9 billion. Thus the demand for food, water and energy will increase rapidly. We need to find more sustainable and environmentally friendly ways to meet this demand without increasing the strain on natural resources. The problem this technology promising future is on food step of FEW (food-energy-water) nexus.
Nanotechnology, which is basically ultra-small partials promises evaluation of precision agriculture in which farmers can control their usage of water, fertilizer and other inputs, thus reduce their waste which leads more sustainable agriculture.
For example, scientists right now researching on nanofertilizer which can be applied to plants by spraying onto their leaves. Studies suggests that such fertilizing method is especially beneficial for environment as fertilizer doesn’t come in contact with soil. On the other hand using typical fertilizer by spreading on field or mixing with irrigation water results excess nitrogen and phosphorus in soil which later can form chemical bonds with other elements and become unavailable for plants to be emitted by their roots. Eventually rain washes the nitrogen and phosphorus into rivers where it can cause pollution problems.
Use nanofertilizer instead of traditional one. You will be using much more less while getting the same or even more benefit without causing waste.
