A study by researchers at CU Boulder and Edinburgh Napier University finds that high-density, low-rise environments such as those found in Paris are the optimal urban form when looking to reduce greenhouse gas emissions over their whole life cycle. There is a growing belief that building taller and denser is better. —Pomponi et al.
waste oils with high FFAs have not been a viable feedstock option. The significant reduction of harsh chemicals and by-products enhances safety for both personnel and the environment. The enzymatic process uses less energy, and the cost of waste oil as a feedstock is significantly lower than refined oils. free fatty acids (FFA).
A team of researchers University of South Florida is using naturally occurring fungi to drive an environmentally friendly recycling process to extract cobalt and lithium from tons of waste batteries. Although a global problem, the US leads the way as the largest generator of electronic waste.
Researchers are integrating tested technologies and developing new ones to break down plastic waste for conversion into useful materials. Researchers are developing new technologies, such as plasma that shoots ‘bullet’ electrons, to break down plastic waste to convert it into useful materials.
Seven of the 28 projects, which will be led by Dr PK Wong, Deputy Director (Research) at A*STAR’s Institute of Chemical and Engineering Sciences (ICES), will develop technologies to capture, store and utilize carbon dioxide effectively to address the level of atmospheric carbon dioxide and reduce its adverse effect on the environment.
In 2012, with California in the midst of a severe drought, Schneider, then a mechanical engineering graduate student at Stanford University , once again tossed out a “cool idea.” With such a device, he thought, people could enjoy a long shower without wasting water. You’d waste more water than you saved.
billion (US$10 billion) for the 2013 work program will support projects and ideas that will boost Europe’s competitiveness and tackle issues such as human health, protecting the environment and finding new solutions to growing challenges linked to urbanization and managing waste. In total, €8.1
It is also supported by ADEMA, the French Agency for the Environment and Energy Control. The idea is to take as little energy as possible from the internal combustion engine. Waste heat recovery. Renault Trucks has developed a system to recover the waste heat contained in exhaust gases.
A new new forum for the advocacy and development of liquid air as an alternative technology to harness waste and surplus energy within power and transport—the Liquid Air Energy Network (LAEN)—has formed in the UK. The main potential applications are in electricity storage, transport and the recovery of waste heat.
These so-called megacities will present a unique challenge to personal mobility, threatening the economy, the environment, and even the health of their residents. New ideas are a priceless resource, and the ultimate driver of economic growth. —Bill Ford. —Bill Ford.
I dont have a problem with the idea that there are engineers who are 10 times as productive as other engineers. When your systems are designed to be used by normal engineers, all that excess brilliance they have can get poured into the product itself, instead of wasting it on navigating the system. It just feels true.
Slocum and some of his students built a 30-inch-diameter prototype in 2011, which functioned well through charging and discharging cycles, demonstrating the feasibility of the idea. MIT has filed for a patent on the system.
Then I almost got carsick with the bag on my head smelling faintly of cilantro as we did what seemed like an endless series of donuts, attempted drifts and all manner of diversion tactics I’m certain were a complete waste of time. “I still have no idea what you’re talking about.” ” “Help you what?”
Plus, battery costs are rapidly decreasing and the public is warming up to the idea of electric cars. In fact, some experts predict electric vehicles (EVs) to account for 65 percent to 75 percent of sales in 2050—which is also good news for the environment. Another hot topic in the auto world is autonomous rides. The solution?
Technologies to address barriers to the use of municipal solid waste and sewage sludge as feedstocks for alternative fuels. Municipal solid waste and sewage are waste products that are produced at massive scale.
Invited to participate as copilot in a trans-Atlantic balloon racewhich he and his teammate won he immediately became seized with the idea of being the first to circumnavigate the globe in a balloon. Jean Revillard/Getty Images How did you get the idea for Climate Impulse? Such a project resonated with his familys history.
Where autonomous vehicles have had the most success is in environments with a lot of predictability and structure, which is why I really like the idea of autonomous urban boats designed for cities with canals. Other challenges are also mitigated, like having to worry about variability in lane markings.
Cutting emissions by 2020 to a level that could keep a global 21 st century temperature rise below 2 °C is technologically and economically feasible, according to a new study released by the UN Environment Programme (UNEP). Waste: about 0.8 Bridging the gap. Click to enlarge. Agriculture: 1.1 Bridging the Emissions Gap.
The proposed idea is to build a small scale process simulator, with both machinery and software components, which mimics aspects of a smart manufacturing system for educational purposes. The goal of this project is to drive out wasted energy in manufacturing facilities through improved information technology. Penn State University.
A team of researchers from the US Department of Energy’s Savannah River National Laboratory (SRNL) is studying how the relationships between blue-green algae and its environment, particularly nutrients and other bacteria, affect its ability to produce hydrogen.
day, representatives from all Volkswagen sites presented their ideas and the measures they have already implemented to reduce the use of resources. The Volkswagen foundry in Hanover uses waste heat from the cooling system in various applications such as heating offices in winter or to heat up drinking water. At the fourth "Think Blue.
(Brooklyn) is building a light-duty electric motorcycle designed to be used in an urban environment, which would reduce pollution and gas consumption. The product is biodegradable, reducing landfill waste, and uses farm refuse normally thrown away. The idea would reduce truck traffic and save on fuel consumption and diesel emissions.
Through work on transgenic plants and wild plants that naturally have fewer undesirable constituents, biologists, engineers and chemists have recently improved the biorefinery field’s understanding of the chemistry and structure of lignin, which provides a better idea of the theoretical chemistry that lignin can do, Ragauskas said.
—Bradley Cardinale, associate professor at the U-M School of Natural Resources and Environment, and team leader. The main goal is to test the idea that certain naturally diverse groups of algae have complementary traits that enhance the efficiency and stability of biofuel yield beyond what any single species can do alone.
We define “green&# by the use of renewable energy, the reduction of greenhouse gas emissions, the savings of energy currently wasted, the most sustainable and conservation-minded water policies, and the most prudent and efficient use of recycling and waste management principles. 4. Waste & Recycling.
The VTO FOA is open to any and all ideas which significantly advance the mission of the VTO. competitive waste heat recovery technologies. based systems for waste?heat Incubator programs allow DOE to assess new technologies for potential to be on-ramped to future MYPPs. miles in passenger vehicles and 435,000 miles for heavy?duty
This is an exciting idea that has the potential to add a scalable alternative into the portfolio of companies looking to reduce their carbon footprint. The need for a defensible new standard has led to the formation of the group, Blackburn said. —Kenneth Medlock.
During his keynote address at the 2012 Mobile World Congress in Barcelona earlier this year, he outlined a plan for connected cars to help avoid a potential future of what he called “ global gridlock—a never-ending traffic jam that wastes time, energy and resources.” ( Earlier post.) Like some other OEMs (e.g.,
Nor did the Commissioners have any ideas for incentives or fast tracking possibilities to encourage more green building in Torrance. That’s the last first Thursday of the month I waste watching a group of well-meaning but ineffective people dick around and accomplish nothing. Fred graciously said he would.
Friction and wear dissipate mechanical energy in moving mechanical assemblies, leading to unwanted material loss and wasted energy. The experimentalists were also puzzled to find that humid environments were causing the friction coefficient to shoot up to levels that were nearly 100 times greater than measured in dry environments.
Because it is very difficult to remove lignin using existing enzymes, this process requires preprocessing with sulfuric acid at high temperatures, which in turn requires preprocessing and treatment of waste liquids and the consumption of large amounts of energy, Moriya says. As a result, says Moriya, they produce oil for buoyancy.
metals such as mercury, cadmium, lead and hexavalent chrome) that pose a known threat to health or the environment. Its goal is to be solvent-free, not just to replace a given solvent with a slightly less toxic alternative, said Bob Proctor, Manager, Environment and Cost Planning, Honda North America. SOCs are chemical (e.g.,
Low-temperature PEM fuel cells that use Nafion are at present being commercialized in fuel cell vehicles, but these cells can operate only at relatively low temperatures and high hydration levels; therefore, they require humidified inlet streams and large radiators to dissipate waste heat.
The anaerobic digester is fed the waste from the distillation process and the wastes from 2,000 dairy cattle and 10,000 beef cattle being raised on the site. Madson identified several ethanol plants that were built in industrial settings that were able to use the waste heat, i.e. from an adjacent refinery, to produce their ethanol.
In Manhattan Beach I’ve been watching the four committees of the ETF present their recommendations for the city council on water, waste, building and climate change. The biggest attribute of this glorious South Bay is our environment. It’s the environment – the sun, the air, the water, the land. Speaking of blowing –.
I find it slightly disconcerting that the Japanese have decided EVs are not the answer – sales cratered by a whopping 33 per cent in 2024 alone – because they tend to be so damn right about everything else (except for killing yourself out of shame when you lose a fight, that idea stinks).
Upper temperature limits and the suitability of waste heat for CHP applications should also be addressed. MEAs for transportation applications should address cold-start and freeze-start, while those for stationary applications should address upper temperature limits and the suitability of waste heat for CHP applications.
It’s no secret that our modern lifestyles put significant pressure on the environment. That’s why we’re launching #TheGreenReset – a national initiative challenging householders worldwide to swap their wasteful ways for environmentally friendly alternatives. Upcycle and recycle projects ideas to try during #thegreenreset.
One problem with mass-producing sensors, however, is that it creates a lot of waste. Vaggeeswar Rajaram/Northeastern University The idea to use infrared light stemmed from Rinaldi's previous project: detecting exhaust fumes from cars. So far, the team has tested their prototypes in the lab environment.
Among them: Our society generates massive amounts of waste that is going to remain in landfills for a long time. What’s more, the process of making these goods is also bad for the environment, considering raw materials, refining, supply chain, packaging, and so on. Unfortunately, there are some deleterious side effects.
Unfortunately, it doesn’t seem as if they will be going away soon, either, as Prime Minister Narendra Modi, who has heavily supported the idea of local manufacturing efforts, will not be forced to leave his post or enter another election until 2024. Is Tesla wasting its time trying to get things going in India? Plain and simple.
The Brandenburg State Office for the Environment (LfU), the responsible approval authority in the matter, has stated that Tesla won’t be violating any rules if it sells good quality early Model Ys to end customers. As a result, “the ancillary provisions contained therein are no longer effective,” Tesla noted. .
It’s almost mid-April, which means that it’s time we spoke to someone new who is making a positive difference to our environment. Ok, first things first, what inspired your idea for Styroloop? The idea for Styroloop stemmed from my MA research, trying to find a solution to the unmanaged waste stream of expanded Polystyrene (EPS).
It seemed to me that recent improvements in reactor designs gave nuclear plants even more potential to deeply decarbonize societies at reasonable cost, while operating safely and dealing with nuclear waste in a responsible way. He offered an idea for a related experiment that had been sitting on the shelf for 20 years.
