Sugar beets are potentially better for ethanol production than corn

with 3 comments

Sugar beets are a more efficient source for ethanol production than corn for a lot of reasons: they use less land, less water and, they can grown in many regions during the winter where it’s too cold to grow corn.

Sugar beets, which are mostly water, use 40 percent less water for growth than corn does, and require about half as much land, according to oil-industry website OilPrice.com. Also, there’s little waste involved in processing sugar beets to alcohol because much of the waste material can be converted to either fuel or fertilizer.

Finding new sources for ethanol is topical because of both rising federal quotas for renewable fuel and the push by many to cut corn-based ethanol production because of concerns over food shortages, waterway contamination and water and electricity requirements. Late last month, U.S. Environmental Protection Agency boosted its 2012 goals for production of non-corn-based biofuels by about 36 percent. This includes quota hikes for sugarcane and algae-based ethanol and cellulosic biofuels, or biofuels produced from grasses, wood and plants. Could sugar beets be the next reasonable large-scale ethanol crop?

The best bet is so-called energy beets which convert more efficiently into sugars for biofuels rather than human consumption.

Finish off your breakfast with — chocolate cake?

with 2 comments

…In a surprising discovery, researchers from Tel Aviv University have found that dessert, as part of a balanced 600-calorie breakfast that also includes proteins and carbohydrates, can help dieters to lose more weight — and keep it off in the long run.

They key is to indulge in the morning, when the body’s metabolism is at its most active and we are better able to work off the extra calories throughout the day…

Attempting to avoid sweets entirely can create a psychological addiction to these same foods in the long-term, explains Prof. Daniela Jakubowicz. Adding dessert items to breakfast can control cravings throughout the rest of the day. Over the course of a 32 week-long study, detailed in the journal Steroids, participants who added dessert to their breakfast — cookies, cake, or chocolate — lost an average of 40 lbs. more than a group that avoided such foods. What’s more, they kept off the pounds longer…

A meal in the morning provides energy for the day’s tasks, aids in brain functioning, and kick-starts the body’s metabolism, making it crucial for weight loss and maintenance. And breakfast is the meal that most successfully regulates ghrelin, the hormone that increases hunger, explains Prof. Jakubowicz. While the level of ghrelin rises before every meal, it is suppressed most effectively at breakfast time.

Basing their study on this fact, the researchers hoped to determine whether meal time and composition impacted weight loss in the short and long term, says Prof. Jakubowicz, or if it was a simple matter of calorie count…

One of the biggest challenges that people face is keeping weight off in the long-term, says Prof. Jakubowicz. Ingesting a higher proportion of our daily calories at breakfast makes sense. It’s not only good for body function, but it also alleviates cravings. Highly restrictive diets that forbid desserts and carbohydrates are initially effective, but often cause dieters to stray from their food plans as a result of withdrawal-like symptoms. They wind up regaining much of the weight they lost during the diet proper.

…The group that consumed a bigger breakfast, including dessert, experienced few if any cravings for these foods later in the day.”

Worth a try. Especially chocolate. Or Nutella.

DOI draft rules require disclosure of fracking chemicals

with 4 comments


Shale gas deposits

The U.S. government will require natural gas drillers to disclose which chemicals they use in hydraulic fracturing on public lands, according to draft rules crafted by the Interior Department…

Companies would be required to disclose the “complete chemical makeup of all materials used” in fracking fluids under the Interior Department’s draft rules, a copy of which was obtained by Reuters…

The Bureau of Land Management estimates that companies use the fracking technique on about 90 percent of wells drilled on federal lands.

The proposed rules would also require drillers to ensure the stability of underground casing in wells and that waste water from fracking does not leak into the environment.

The Interior Department has said it is moving ahead with the rules but has not offered a specific timeline for when they will be released. Once the proposal is officially issued, the department will get feedback before finalizing the regulations…

Fracking has helped companies tap vast reserves of natural gas that could turn the United States into an exporter of the fuel. But environmental groups and some residents near fracking operations say the process pollutes the water and air…

The energy industry complained that the draft rules were overkill as companies were voluntarily revealing the fluids. U.S. law does not require disclosure of fluids used in fracking on federal lands…

One of the largest natural gas drillers, Chesapeake Energy Corp, said it has been voluntarily disclosing its information on chemicals for nearly a year on all its wells on public or private lands on a web site called www.fracfocus.com .

Some of the drillers – like Chesapeake – support voluntary disclosure. In general, I believe corporate commitment to transparency is about as realistic as the sun rising in the West or the leadership of the Republican Party suddenly accepting guidance from the National Institute of Science.

Not on your tintype, Nellie! I choose regulation and oversight.

Obama proposing a tax credit for natural gas-powered trucks

with one comment

President Barack Obama pitched a plan on Thursday to boost U.S. use of natural gas and open more land for offshore drilling during a campaign-style tour aimed at bolstering confidence in his economic stewardship.

At a stop in Las Vegas, Nevada, the Democratic president sought to counter Republican criticisms of his energy policies as he proposed tax incentives for companies to buy natural gas trucks, which would help build demand for abundant domestic supplies of the fuel…

Obama said the United States needs an “all-out, all-in, all-of-the-above strategy” to develop energy resources at home and that doing so would create American jobs…”A great place to start is with natural gas,” Obama said during a visit to a UPS facility in Las Vegas, which received stimulus funding to invest in liquefied natural gas vehicles and build a public LNG refueling station.

“We’ve got a supply of natural gas under our feet that can last America nearly a hundred years,” he said. “Developing it could power our cars, our homes, and our factories in a cleaner and cheaper way. The experts believe it could support more than 600,000 jobs by the end of the decade…”

Using domestic natural gas as a cleaner alternative to importing foreign oil has been heavily promoted by Texas oil billionaire T. Boone Pickens and has attracted support from both sides of the aisle in Congress.

Still, Obama’s natural gas truck proposal, which would need congressional approval, could face an uphill battle to make it into law. Republicans, campaigning on promises to cut government spending, would likely resist costly energy subsidies…

Obama also announced that the Interior Department will hold the last scheduled offshore lease sale of the government’s current five-year drilling plan in June, offering 38 million acres for development in the central Gulf of Mexico…

Analysts said those results were a sign that drilling is rebounding in the Gulf after the administration temporarily shut down deepwater exploration after the BP disaster.

The Oil Patch Boys are still whining, of course, about oversight and regulations being resumed. They became accustomed to doing just about anything they wished during the Bush/Cheney years. Reality began to return with the BP oil spill in the Gulf of Mexico – not that oil companies ever cared much for reality if it hinders profits.

NatGas tech is already advanced enough that some auto companies that sell pickup trucks will be offering a natural gas option in addition to clean diesel. For less than the additional cost of diesel. That’s pretty amazing.

We have the first natural gas-powered bus fleet in the country here in Santa Fe and it is a boon keeping our clean air clean. The cost in gasoline equivalent has risen over the years to $1.61/gallon. With serious federal help, it could be less.

Scientists create Borg cockroach that produces its own electricity

with one comment


 
An insect’s internal chemicals can be converted to electricity, potentially providing power for sensors, recording devices or to control the bug, a group of researchers at Case Western Reserve University report.

The finding is yet another in a growing list from universities across the country that could bring the creation of insect cyborgs – touted as possible first responders to super spies – out of science fiction and into reality. In this case, the power supply, while small, doesn’t rely on movement, light or batteries, just normal feeding…

“It is virtually impossible to start from scratch and make something that works like an insect,” said Daniel Scherson, chemistry professor at Case Western Reserve and senior author of the paper. “Using an insect is likely to prove far easier,” Scherson said. “For that, you need electrical energy to power sensors or to excite the neurons to make the insect do as you want, by generating enough power out of the insect itself.”

Scherson’s team…developed an implantable biofuel cell to provide usable power…

The researchers found the cockroaches suffered no long-term damage, which bodes well for long-term use.

The researchers are now taking several steps to move the technology forward: miniaturizing the fuel cell so that it can be fully implanted and allow an insect to run or fly normally; investigating materials that may last long inside of an insect, working with other researchers to build a signal transmitter that can run on little energy; adding a lightweight rechargeable battery.

“It’s possible the system could be used intermittently,” Scherson said. “An insect equipped with a sensor could measure the amount of noxious gas in a room, broadcast the finding, shut down and recharge for an hour, then take a new measurement and broadcast again.”

Or photograph a famous politician having illicit sex.

RTFA for the technology and science.

Thanks, Ursarodinia

Italian drill rig arrives in Cuba to begin deep water oil exploration

leave a comment »


Scarabeo 9 – owned by Italy’s Saipem
Daylife/Reuters Pictures used by permission

A large oil rig has arrived off the coast of Cuba to begin searching for offshore oil deposits.

Several international companies will use the rig to drill exploratory wells in deep water in the Florida Strait, which separates Cuba from the US. Cuba is hoping to confirm estimates that it has billions of barrels of oil in offshore fields.

But there is concern in the US that a deep water spill could devastate the coast of Florida.

Semi-hogwash! Concern from American companies forbidden by idiotic laws from bidding on the contracts? Worries from my environmental peers who never noticed the thousands of wells drilled safely round the world – until BP and Halliburton screwed-up in the Gulf of Mexico?

The Chinese-built rig – known as Scarabeo 9 – could be seen from the Cuban capital Havana as it moved slowly west.

First to use it will be the Spanish oil company Repsol YPF, which plans to drill an exploratory well around 100km from the Florida Keys. Other foreign companies are also planning to hire the rig…

If confirmed, the estimated offshore deposits could turn Cuba into an oil exporter and transform its troubled socialist economy…

Repsol has said that its operations will comply with all US safety regulations, and the rig has been inspected by US officials.

Hopefully, the Spanish company will live up to the general standards for deepwater drilling which are more demanding and rigorous than what passes for regulations in the United States.

BITD – when I worked in offshore oil drilling construction – standards and regulations were built up to a pretty high standard in the US. In the last couple of decades, the government agencies providing oversight became nothing more than party buddies of Big Oil. The regulations became a farce. Drilling rigs coming in from duty, say, off Brazil or Norway, were instructed to remove some of the redundant safety systems – which was done on the TransOcean Deepwater Horizon rig.

The ongoing boycott of normal relations with Cuba is a special category of stupid.

Dakar results: X-Raid diesel-power Minis 1st, 2nd — 5 in Top 10

leave a comment »

Stéphane Peterhansel celebrated his 10th Dakar win, representing at the same time the MINI ALL4 Racing’ and the X-raid Team’s first triumph in the gruelling event! Just 14 months after the unveiling of the German squad’s latest vehicle, the off-road racing crown was secured by the Trebur based team…

But the success story didn’t end with Peterhansel’s win, as all the five MINIs ALL4 Racing entered by the team made it to the top 10. Nani Roma (ESP) ad Michel Périn (FRA) impressed by celebrating three special-stage wins and finished runner-up, thus giving the Monster Energy X-raid Team a one-two, in the 2012 Dakar. Meanwhile, Russia’s Leonid Novitskiy and his German navigator Andi Schulz demonstrated that consistency is the right approach for being successful. They won the first special stage and afterwards, they successfully avoided getting involved in any major problems. Finishing fourth in the overall rankings represented the well-deserved reward – and the best Dakar result ever secured by a Russian driver in the Dakar’s car ranking. In addition, Novitskyi also was the best-place semi-professional driver in the 2012 edition of the event.

For a long time, Polish-Belgian pairing Krzysztof Holowczyc / Jean-Marc Fortin also proved to be a factor in the battle for a top-three position. In the 10th special stage, however, their ORLEN MINI ALL4 Racing encountered problems that cost them their chance of making it to the podium. The fifth Monster Energy X-raid Team pairing, the Portuguese Ricardo Leal dos Santos und Paulo Fiuza, completed the outstanding team success by taking their red MINI ALL4 Racing to eighth position in the overall rankings.

And the Monster Energy X-raid Team did not only convince by this fantastic Dakar success but also by outstanding reliability. Other than expected by many pundits, all the eight vehicles entered by the German squad – five MINIs ALL4 Racing and three BMWs X3 CC – survived the entire event and made it to the finish in Lima. “Apart from our win, this is the biggest success for our team,” added Quandt. “Our engineers and mechanics did a fantastic job preparing the cars on every single day, thus laying the foundation for this success…”

Dakar record winner Peterhansel switched to Team x-raid following the 2009 Dakar. Up to that point in time, Mr. Dakar had celebrated 6 motorbike wins (1991, 1992, 1993, 1995, 1997, 1998) and three on four wheels (2004, 2005, 2007), in the legendary event. Now, by his first win in South America, he added triumph No 10 – by delivering in his well-known style. Peterhansel celebrated three special stage wins in this year’s Dakar and convinced – as usual – by consistency and a matured style of driving. Thanks to this approach, he avoided getting involved in any major problems and on day three, he took the lead for the second time to defend it until the rally was over…

I’ve followed the X-Raid team for a decade, now. This year’s victory – their first in the Dakar – succeeded beyond wildest expectations. Essential to their effort has been the reliability of diesel racing engines. This year’s 6-cylinder, twin-turbo BMW powerplant running flawlessly throughout. The all-wheel-drive Minis were stellar.

Congratulations, folks, on a terrific team and a superlative victory.

Admin and tech questions OK for nuclear plant construction

leave a comment »

The Nuclear Regulatory Commission unanimously approved a radical new reactor design on Thursday, clearing away a major obstacle for two utilities to begin construction on projects in South Carolina and Georgia.

The decision, a milestone in the much-delayed revival of plant construction sought by the nuclear industry, involves the Westinghouse AP1000, a 1,154-megawatt reactor with a so-called advanced passive design. It relies more heavily on forces like gravity and natural heat convection and less on pumps, valves and operator actions than other models do, in theory diminishing the probability of an accident.

Which says nothing about cost overruns, kickbacks for lobbyists and political graft in construction.

Two reactors are planned for the Southern Company’s plant near Augusta, Ga., and another two at the Summer plant of South Carolina Electric and Gas in Fairfield County, S.C.

India begins living up to ambitious goals for solar power

with one comment

Solar power is a clean energy source. But in this arid part of northwest India it can also be a dusty one.

Every five days or so, in a marriage of low and high tech, field hands with long-handled dust mops wipe down each of the 36,000 solar panels at a 63-acre installation operated by Azure Power. The site is one of the biggest examples of India’s ambitious plan to use solar energy to help modernize its notoriously underpowered national electricity grid, and reduce its dependence on coal-fired power plants.

Azure Power has a contract to provide solar-generated electricity to a state-government electric utility. Inderpreet Wadhwa, Azure’s chief executive, predicted that within a few years solar power would be competitive in price with India’s conventionally generated electricity…

Two years ago, Indian policy makers said that by the year 2020 they would drastically increase the nation’s use of solar power from virtually nothing to 20,000 megawatts — enough electricity to power the equivalent of 20 million modern American homes. Many analysts said it could not be done. But, now the doubters are taking back their words.

Dozens of developers like Azure, because of aggressive government subsidies and a large drop in the global price of solar panels, are covering India’s northwestern plains — including this village of 2,000 people — with gleaming solar panels. So far, India uses only about 140 megawatts, including 10 megawatts used by the Azure installation, which can provide enough power to serve a town of 50,000 people, according to the company. But analysts say that the national 20,000 megawatt goal is achievable and that India could reach those numbers even a few years before 2020.

Prices came down and suddenly things were possible that didn’t seem possible,” said Tobias Engelmeier, managing director of Bridge to India, a research and consulting firm based in New Delhi. Chinese manufacturers like Suntech Power and Yingli Green Energy helped drive the drop in solar panel costs. The firms increased production of the panels and cut costs this year by about 30 percent to 40 percent, to less than $1 a watt.

Developers of solar farms in India, however, have shown a preference for the more advanced, so-called thin-film solar cells offered by suppliers in the United States, Taiwan and Europe. The leading American provider to India is First Solar, based in Tempe, Ariz.

India does not have a large solar manufacturing industry, but is trying to develop one and China is showing a new interest in India’s growing demand. China’s Suntech Power sold the panels used at the Azure installation, which opened in June.

RTFA. Lots if info. I chuckle when folks writing articles like this include notes about government subsidies being necessary. I don’t recall a major power plant built anywhere in the world – coal-fired, nuclear, nat gas, whatever – in decades without government support. It ain’t exactly the kind of construction project done on spec.

Visualizing Asian energy consumption

leave a comment »


Click on graphic or refresh to see animation

I’ve heard it many times before. Remarkable growth in Asia is leading to big increases in coal consumption and carbon-dioxide emissions. But I didn’t have a good sense of just how big that change has been until I saw this graphic from the U.S. Energy Information Administration.

Asia’s coal use was smaller than Europe’s in 1980. Now it dwarfs coal consumption even in North America, the world’s second-largest consumer.

Stunning – as a reflection of fossil fuel consumption, energy production. Without differentiating the portion of coal consumed as metallurgical versus thermal coal we’re still looking at enormous growth in industrial potential.

The concurrent pollution problems help to understand why China is fast becoming the world’s leading manufacturer of alternative energy devices. Their conversion rate to solar and wind power is close to first – though still behind Europe. They’re trying equally fast to catch up to and surpass nations like France in nuclear power generation. They have to. That burgeoning middle class is starting to make lifestyle demands to match their growing wealth and education.
