The supercar uses a flywheel to store energy and provide it with a power boost when desired.
The body of this Ferrari hybrid is expected to be 20% lighter than the Ferrari Enzo, and should reduce its emissions by 40%.
Most people know that the weight of automobiles has an impact on its efficiency and performance, but what matters is how much.
To give you an idea of just how significant the issue of vehicle weight is, almost all of the power that a vehicle requires is dedicated to moving the vehicle’s own weight — the weight of the passengers is nothing compared to it. This is one of multiple reasons why small cars and motorcycles are more fuel-efficient than large cars.

The institute, which was devoted to the ‘study’ of hydraulic fracturing, was heavily criticized after the release of its first study back in May, due to its very noticeable bias towards the oil and gas industry.
In an address to the “university community," President Satish K. Tripathi said: "It is imperative that our faculty members adhere to rigorous standards of academic integrity, intellectual honesty, transparency and the highest ethical conduct in their work."
The University of Texas at Austin is currently conducting a similar investigation of a fracking study that it released earlier this year. It came out that one of the professors who ‘fostered’ the study was on the board of a gasoline company… and had never disclosed that.
These controversies are a bellwether of sorts. There have been growing concerns about the influence of corporate money in academic research, especially now that government grants are declining.
"The people who signed the petition feel that their public university needs to remain a public university and not a mouthpiece for corporations," said Jim Holstun, an English professor at the university who questioned the credibility of the institute.
The study had stated that drilling was becoming much safer in Pennsylvania thanks to state regulation, and that New York's pending rules would create the same effect.
After the study was released, the Public Accountability Initiative, which is a local government watchdog group, began questioning some of the study's data and conclusions. And also questioning the lack of full disclosure from its lead authors, who have conducted research directly for the industry.
Amongst them, the third author, and the shale institute's co-director, John P. Martin, worked for the industry doing planning and public relations.
Dr. Tripathi has said “that as a result of the transparency issues raised by the now-defunct shale institute, a committee that includes the faculty senate would meet to recommend how to strengthen policies for disclosing financial interests and sources of support in research going forward. He said the university would continue to pursue studies on energy and the environment.”

State-owned utility Sonelgaz, is expected to build 4.2 GW of renewables itself, providing underlying support towards Algeria's goal.
Next year will see the first phase of the ambitious project, which will eventually include solar photovoltaic energy, concentrated solar power, and wind energy. As noted by PV Tech:
Besides Sonelgaz's commitment to wind and solar, the utility also has a deal with the Desertec CHP project, to look at possibly exporting 1 GW to European countries.
With lots of sun to harness, Algeria, if it succeeds, could be a renewable energy market to watch out for in the years to come.

The brief – Transitioning away from large-scale power projects: A simple and effective fix for the CDM? – shows how large-scale power supply projects such as large hydro and coal undermine the integrity of the CDM. Instead, it proposes that governments and the CDM administration transition away from them. The policy brief builds on an analysis they conducted for the CDM Policy Dialogue, which was published in late October in the report Assessing the Impact of the CDM.
Below are its key findings:
Currently, the oversupply of CERs has plummeted the price of each CER to approximately €1 apiece. According to the High Level Panel, between 2013 and 2020, the excess of CERs could be as many as 1.25 billion. However, says SEI, a transition away from large-scale infrastructure projects (those greater than 15 MW) could reduce this over-supply and instead refocus attention on more effective ways of supporting the low-carbon energy sector while reducing emissions, such as through nationally appropriate policies and measures (NAMAs; these include renewable energy standards, feed-in tariffs, efficiency programs and standards), domestic emission trading systems, and carbon taxes.
Why target large-scale power projects? Because researchers have shown for years that the most serious additionality concerns are attached to large-scale projects like hydropower, as well as wind, natural gas, high-efficiency coal, waste energy, and to a lesser extent, biomass. Such large-scale projects simply do not need CDM support, because they are already common practice in their countries, enjoying benefits such as feed-in tariffs, mandates, and other forms of government or private support and incentives.
In addition, according to SEI, “the CDM, on average, has a small effect (e.g. ~3% for wind and hydropower) on the expected rate of return of power sector projects,” and compared to other normal variations in economic factors, it is unclear whether the CDM provided enough of an incentive for projects to happen. In other words, continued use of non-additional CERs from large-scale projects could actually increase global emissions of greenhouse gases, rather than mititgate or reduce them (as was the original intended purpose of the CDM). While power projects only represent a quarter of CERs issued so far, they are expected to generate almost 70% of total CERs from 2013 to 2020, with large-scale projects representing 90% of those power-sector CERs.
The SEI policy briefing also warns against some of the short-term fixes recommended by the CDM Policy Dialogue, one of which is for the Green Climate Fund or other funds to buy up and cancel the surplus CERs. The brief warns that such an option could be costly, divert climate finance from other mitigation or adaptation activities, and that its mitigation benefit would be uncertain due to the poor confidence in the additionality of these registered projects. The only effective and straight-forward solution, therefore, is to transition away from large-scale power projects.
How do you accomplish such a transition? The SEI briefing offers the following recommendations:

Researchers from King’s College London have developed a detailed process to separate colors and create ‘rainbows’ on a metal surface by utilizing nanoscale structures. This method will likely lead to improved solar cells and LED displays, according to the researchers.
The modern discovery of how to separate and project different colors was actually also made at King’s College, more than 150 years ago. This discovery led to the development of color televisions and other displays. In modern research, the primary goal has been for the manipulation of color on the nanoscale. When this capability is further developed it will lead to great changes in imaging and spectroscopy, the sensing of chemical and biological agents, and also (likely) to better solar cells, LED displays, and TV screens.
In the new research, light of different colors was ‘trapped’ at different positions of a nanostructured area, by using nanostructures designed specifically for this function. Specific to the nanostructure’s geometry, a ‘trapped’ rainbow “could be created on a gold film that has the dimension on the order of a few micrometers — about 100 times smaller than the width of a human hair.”
Professor Anatoly Zayats explains: “Nanostructures of various kinds are being considered for solar cell applications to boost light absorption efficiency. Our results mean that we do not need to keep solar cells illuminated at a fixed angle without compromising the efficiency of light coupling in a wide range of wavelengths. When used in reverse for screens and displays, this will lead to wider viewing angles for all possible colors.”
The primary difference between natural rainbows and these artificial rainbows is that the researchers can actually control where and in what order the colors appear, simply by altering the nanostructures’ parameters. And in addition to this, they can also separate colors to appear on different sides of the nanostructures.
“The ability to couple light to nanostructures with multicolour characteristics will be of major importance for light capturing devices in a huge range of applications, from light sources, displays, photo detectors and solar cells to sensing and light manipulation in optical circuits for tele and data communications.”
The new research is published in Nature’s Scientific Reports.

The new research is following on the heels of the devastating fires that were caused by natural gas leaks during Hurricane Sandy. Safety concerns have been raised because of potential flooding damage that may have been done to the gas pipeline pressure regulators located there.
As a result of the research in Boston, more than 3,356 separate natural gas leaks under the streets of Boston were found. “While our study was not intended to assess explosion risks, we came across six locations in Boston where gas concentrations exceeded the threshold above which explosions can occur,” said Nathan Phillips, co-author of the study, and an associate professor in BU’s Department of Earth and Environment.
In the U.S., natural gas pipeline failures kill an average of 17 people every year, cause 68 injuries, and cause around $133 million in property damage, according to the U.S. Pipeline and Hazardous Materials Safety Administration. Natural gas leaks are also a major environmental problem because natural gas is almost entirely methane, a very-potent greenhouse gas that also lowers air quality. The leaks are also simply a significant loss of resources. Over $3 billion of natural gas is lost every year in the U.S. due to leaks.
“Repairing these leaks will improve air quality, increase consumer health and safety, and save money,” said co-author Robert B. Jackson, Nicholas Professor of Global Environmental Change at Duke. “We just have to put the right financial incentives into place.”
The researchers conducted the research by using a “new, high-precision methane analyzer” installed in a GPS-equipped car to map the gas leaks under Boston. They then drove over all the 785 road miles within the city limits, discovering the 3,356 known leaks.
Boston’s not unique in these regards, though — most other aging cities around the globe have old pipeline infrastructure that is likely to be leaking. The researchers are highly-recommending that ‘coordinated gas-leaks mapping campaigns’ be developed in cities where the old infrastructure is likely to be a significant risk. “The researchers will continue to quantify the health, safety, environmental, and economic impacts of the leaks, which will be made available to policymakers and utilities as they work to replace and repair leaking natural gas pipeline infrastructure.”
The new research is being published this week in the online edition of the peer-reviewed journal Environmental Pollution.
