BP CEO Tony Hayward's testimony before the House Energy and Commerce

British press turns on Hayward, with plenty of anti-Obama rage thrown in for good measure

Tony Hayward AP – BP CEO Tony Hayward testifies during a House Oversight and Investigations subcommittee hearing on the …

Many in the British press have slammed the U.S. government lately for demonizing BP, instead of simply holding the company accountable for the Gulf oil spill.

But that sentiment has shifted noticeably since BP CEO Tony Hayward's testimony before the House Energy and Commerce committee Thursday. Hayward's inability (or unwillingness) to answer a number of direct questions about the decision-making that preceded the spill cost him many of his job responsibilities today — together with a good deal of his erstwhile cheering section in the British press.

The Times (of London) didn't go easy on the oil executive, summing up its analysis of his performance in Washington with the headline: "From Mr. Bean to Mr. Has-been for BP's Tony Hayward."

The Times' Giles Whittell wrote that Hayward "had a chance to save his career and the good name of his company by giving forthright, detailed answers to highly specific questions submitted in advance by two of the most astute and enlightened men in Congress." Instead, Hayward, he wrote, "seemed to have prepared by taking beta blockers."

Whittell argued that Hayward stonewalled congressional interrogators, despite the executive's claims to the contrary. The Guardian clearly agreed with that assessment in its own piece on the hearing:  "BP oil spill: Tony Hayward stonewalls Congress."

Although Hayward was "carefully coached by legal and media teams and was testifying under oath," the Guardian noted, he "failed to satisfy." Also, according to the Guardian, Hayward delivered his answers "in flat, impassive tones."

In the Telegraph, PR branding specialist Mark Borkowski wrote that  "Hayward's communication skills didn't rival those of a tax inspector."

"The new age demands a front-and-centre spokesman who can make the audience feel like he is listening and actually gives a damn," Borkowski wrote. "But Tony Hayward doesn't seem to have learned a great deal about being inclusive, about engaging with the public."

"Accused of stonewalling, he stonewalled," Borkowski continued. "He couldn't, or wouldn't, answer most of the questions. In fact, he looked like a tired undertaker who was rather bored with having to look mournful."

Still, other British commentators had plenty of rancor left for the United States and its political leaders. Rupert Cornwell, a columnist for the Independent, added to the criticism that others in the British press have leveled against the Obama administration and Congress — that they're unfairly piling on BP even as the company tries to clean up its mess. Cornwell wrote that "yesterday's grilling of Mr. Hayward ... is a 21st-century version of the medieval stocks, public disgrace for the public villain of the moment."

While Cornwell harkened back to medieval times to describe Hayward's treatment on Capitol Hill, the Daily Mail went back even further for a historical comparison. The British paper reported that Hayward was "subjected to a grilling so savage yesterday it was more like ancient Rome than Capitol Hill."

"Wave after wave of criticism flew the way of the hapless boss and his company," the Daily Mail continued, "confirming them both as Public Enemy No. 1 in the U.S."

The Economist, more highbrow than the typical Fleet Street tabloid, came out swinging at the Obama administration in the issue on newsstands Friday. However, the Economist's ire isn't motivated by jingoism or knee-jerk America-bashing — it's far too genteel for such tabloid sport. Instead, backed by its faith in free markets and neo-liberal trade policies, the Economist  came out in support not just of a British company but of business itself, which it judged to be unfairly maligned in the spill fiasco.

 "America's justifiable fury with BP is degenerating into a broader attack on business," the Economist's editors wrote in today's lead editorial.

The Economist expressed concern that business leaders who are "already gloomy, depressed by the economy and nervous of their president's attitude towards them" will likely not be encouraged by the treatment of BP.

Because Obama's now pushing "firms into doing his bidding" — the magazine's characterizaion of efforts to hold BP responsible for an environmental catastrophe of its own making — the Economist draws parallels between the president and Russia's strong-armed former president and current prime minister. Hence the editors' new nickname: "Vladimir Obama."

So while Tony Hayward is now a tarnished British hero in the Tony Blair vein, national morale may well rebound with the prospect of a good old colonial trade war — or Cold War, as the case may be.

Solar Efficiency Breakthrough

News Release

U of M researchers have cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels.

University of Minnesota researchers clear major hurdle in road to high-efficiency solar cells

Contacts: Preston Smith, University News Service, smith@umn.edu, 612-625-0552

MINNEAPOLIS / ST. PAUL (06/17/2010) —A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent.

By showing how energy that is now being lost from semiconductors in solar cells can be captured and transferred to electric circuits, the team has opened a new avenue for solar cell researchers seeking to build cheaper, more efficient solar energy devices. The work is published in this week's Science.

A system built on the research could also slash the cost of manufacturing solar cells by removing the need to process them at very high temperatures.

The achievement crowns six years of work begun at the university Institute of Technology (College of Science and Engineering) chemical engineering and materials science professors Eray Aydil and David Norris and chemistry professor Xiaoyang Zhu (now at the university of Texas-Austin) and spearheaded by U of M graduate student William Tisdale.

In most solar cells now in use, rays from the sun strike the uppermost layer of the cells, which is made of a crystalline semiconductor substance—usually silicon. The problem is that many electrons in the silicon absorb excess amounts of solar energy and radiate that energy away as heat before it can be harnessed.

An early step in harnessing that energy is to transfer these "hot" electrons out of the semiconductor and into a wire, or electric circuit, before they can cool off. But efforts to extract hot electrons from traditional silicon semiconductors have not succeeded.

However, when semiconductors are constructed in small pieces only a few nanometers wide -- "quantum dots" -- their properties change.

"Theory says that quantum dots should slow the loss of energy as heat," said Tisdale. "And a 2008 paper from the University of Chicago showed this to be true. The big question for us was whether we could also speed up the extraction and transfer of hot electrons enough to grab them before they cooled. "

In the current work, Tisdale and his colleagues demonstrated that quantum dots—made not of silicon but of another semiconductor called lead selenide -- could indeed be made to surrender their "hot" electrons before they cooled. The electrons were pulled away by titanium dioxide, another common inexpensive and abundant semiconductor material that behaves like a wire.

"This is a very promising result," said Tisdale. "We've shown that you can pull hot electrons out very quickly – before they lose their energy. This is exciting fundamental science."

The work shows that the potential for building solar cells with efficiencies approaching 66 percent exists, according to Aydil.

"This work is a necessary but not sufficient step for building very high-efficiency solar cells," he said. "It provides a motivation for researchers to work on quantum dots and solar cells based on quantum dots."

The next step is to construct solar cells with quantum dots and study them. But one big problem still remains: "Hot" electrons also lose their energy in titanium dioxide. New solar cell designs will be needed to eliminate this loss, the researchers said.

Still, "I'm comfortable saying that electricity from solar cells is going to be a large fraction of our energy supply in the future," Aydil noted.

The research was funded primarily by the U.S. Department of Energy and partially by the National Science Foundation. Other authors of the paper were Brooke Timp from the University of Minnesota and Kenrick Williams from UT-Austin.

15 Ways to Stay Cool & Save

With summers trending hotter and budgets getting tighter, it's tough to stay cool. Here's how to reduce your summer energy bills without breaking the bank.


Replace Your Windows

According to the EPA, Energy Star-qualified windows can save the typical household $125-$450 per year in energy costs when replacing single-pane windows and $25-$110 per year when replacing double-pane clear-glass windows.

What makes a window energy-efficient?

-- Improved frame materials such as wood composites, vinyl, and fiberglass reduce heat transfer and improve insulation.
-- Low-E glass with special coatings reflects infrared light, keeping out summer heat.
-- Gases between the panes, such as argon or krypton, insulate better than regular air.
-- Multiple panes of glass with air or gas in between insulate better than a single pane.
-- Warm-edge spacers keep a window's panes the correct distance apart to reduce heat flow and prevent condensation.

The Solar Roadrunner

Feature
Highways basking in the hot sun are wasted energy. Scott Brusaw's solution? Make them out of solar panels

Scott Brusaw's Solar Roadways Kevin Hand

The road ahead is paved with photovoltaics. That's how Scott Brusaw sees it, anyway. His company, Solar Roadways, is embedding PV cells and LED lights into panels engineered to withstand the forces of traffic. The lights would allow for "smart" roadways and parking lots with changeable signage, while the cells would generate enough energy to power businesses, cities and, eventually, the entire country.

Each 12-by-12-foot Solar Roadway panel would produce about 7,600 watt-hours a day, based on an average of four hours of sunlight. At that rate, a one-mile stretch of four-lane highway could power about 500 homes. "If we could ever replace all the roads in the U.S., then, yeah, we would produce more electricity than we use as a nation," says Brusaw, an electrical engineer who completed his first prototype panel in February with funding from the U.S. Department of Transportation.

Brusaw's goal is to get the cost per panel under $10,000. That's roughly three times the cost of asphalt. But he wants to make panels that last three times longer than asphalt roads, which have to be resurfaced every 10 years in many places. "Then the cost is about the same," he says. "But that's just a break-even. We're also generating electricity."

The key to commercial viability will be the panels' glass. It must be textured for traction, embedded with heating elements for melting away ice and snow, and able to survive years of traffic. "The toughest is going to be that fast lane on the highway," Brusaw says, "where you've got a 40-ton truck, maybe with snow chains. It will have to be able to withstand all that." At the same time, it has to be self-cleaning if sunlight is to reach the PV cells; Brusaw points to experimental hydrophilic glass that uses sunlight to break down organic dirt, and rainwater to wash it away without streaking.

Next up for Solar Roadways will be qualifying for Phase II funding, a two-year, $750,000 deal to develop a commercial plan for the panels. At the end of those two years, Brusaw would like to be ready for testing in parking lots, which he sees as the perfect proving grounds for the lights and the power-generation system. Directional arrows and parking lines could be reconfigured to deal with busy times, and the electricity generated could feed adjacent businesses. "I talked to the guy in charge of power for Wal-Mart," Brusaw says. "Superstores are roughly 200,000 square feet, and parking lots are about four times that. I crunched the numbers for an 800,000-square-foot lot and told him how much power it could generate even if it was completely full of cars. It was 10 times the power they use."

Brusaw wants to start smaller, though—on the scale of, say, a fast-food restaurant. A McDonald's retrofitted with a solar parking lot could take itself largely or entirely off the grid or become a site for recharging electric vehicles (while the owners stopped inside for food, naturally). "Even the best electric cars have a range of about three hours," he explains. "But if all I have to do is find a McDonald's, I could drive from Idaho to the southern tip of Florida." Improbable? Yes. But "Billions of watts served" would be a cool new tagline.

Best And Worst Home Improvements For The Buck

Boosting a home's value is easier--and cheaper--than you might think

By Stephane Fitch, Forbes.comJun 17th, 2010

If you plan to sell your home in the next year, you're probably keen on finding a few ways to gin up its value. For many people that means donning an old pair of overalls, pulling out the power tools and going to work on some ambitious renovation projects.

Here's a smarter idea: Leave the work duds in the closet, the tools in the garage and the renovation plans on hold. Instead, get out a large trash can and a dust rag.

20 Best And Worst Home Improvements For The BuckWhere America's Money Is Moving

"Just clean up your act," says Chicago real estate agent Zack Sudler. "Put your junk in a storage locker, neaten, fix the wobbly ceiling fan--and do it before you call your Realtor."

An important point that many home sellers fail to realize: Their first sales job involves hiring a top-notch agent. Many of the best professional home sellers will shy away from putting a lot of time into selling your home if it's a mess.

The only home improvement Sudler recommends is painting. Even there, he advises limiting the work to covering blemishes and repainting any rooms that have overly bright or outdated colors.

On the bigger pre-sale improvement projects, real estate pros tend to have a fairly uniform view: They're rarely worth the money and effort. For most, the value added is a mere fraction of the cost.

To be sure, home renovations can have enormous benefits--to residents rather than sellers. Air conditioning or a new kitchen might dramatically improve your lifestyle. But the incremental amount a buyer will pay for a home after such projects are completed is likely to be well below the seller's cost.

"We've seen homes where sellers have contractors still toiling away when the open houses start," says Patrick Lashinsky, chief executive of San Francisco-based realty agency ZipRealty. "It's a nightmare."

The National Association of Realtors conducts an annual survey of its members in 80 cities that is created by Remodeling magazine and used to estimate the return on investment for 33 home improvement projects. The 2009 report concluded that, on average, for every $1,000 homeowners spend on projects, they get back $638.

Even projects normally hyped as sure bets for adding value generate surprisingly weak gains, NAR reports. Converting an attic into a bedroom, for example, is typically regarded as garnering interest among potential buyers who might have otherwise disqualified the home from their search. An extra bedroom will indeed add value--just not for the majority of people who spend on the conversion. NAR figures homeowners recoup $831 on average for every $1,000 they invest.

Kitchens and bathrooms remain two of the most popular upgrades, and do have among the best returns on remodeling investments. But even for these rooms, mid-range jobs, which offer the highest returns, yield only about $720 and $710, respectively, on average, for each $1,000 invested.

The only investment that tends to get more out of buyers than sellers put into it is a heavy, insulated steel entry door, according to the NAR/Remodeling survey. Spend $1,000 on such an upgrade and you're likely to add $1,289 to your sale price.

If you're looking for examples of ways to waste money on renovations, there are lots of choices. Remodeling a home office yields just $481 for every $1,000 invested. Buying a backup power generator (perhaps from the likes of Honda or Briggs & Stratton) will add only $589 for each $1,000 invested.

All this is anathema to retailers like Home Depot, Lowe's, Bed, Bath & Beyond, Williams-Sonoma and Lumber Liquidators. They all benefit from the myth that pumping money into your house pays off later on the auction block. So do buildings materials firms like Chicago-based USG, maker of the popular Sheetrock brand of gypsum wallboard.

Lashinsky says that on occasion, buying a new appliance for your home can pay off--if the one being replaced is so horribly out of date that it unsettles potential bidders. The agent has a long list of bad ideas to avoid. Among them: Converting a bedroom into a home office and yanking out the closet to make the room look bigger.

"In quite a few states, you're not allowed to list that as a bedroom anymore," he says. Such renovations can be expensive and result in the loss of bidders who need the extra bedroom.

Lashinsky's choice for all-time worst renovation: A family that tore out a long wooden stairway leading up to their lovely hillside home and replaced it with a newly paved path. They made the change right before putting the home on the block in mid-winter, and the path kept icing over.

"People who wanted to see the house literally couldn't get up the path," says Lashinsky. "They kept sliding back down every time they got near the place."

10 Best And Worst Home Improvements For The Buck

Best Improvement: Clean Up
Cost: Negligible
Give your home a top-to-bottom cleaning or, better yet, hire a pro to do a deep clean. Do it even before you hiring a real estate agent. If you don't have a regular cleaner, hire one to keep the place tidy until your house is sold.

Good Improvement: Simple Repairs
Cost: Negligible
It is well worth the modest cost to fix broken outlets, tiles, light switches, door latches, folding doors and ceiling fans. Buyers view such flaws as signs of deeper problems--and may lower their bids accordingly.

Good Improvement: Store Your Clutter
Cost: $100 a month
A 10-foot-by-10-foot locker at Public Storage or one of its competitors is likely to cost you less than your phone and cable bills. Move out unneeded dishes, linens, personal items and furniture. Try to empty closets. Your house will appear bigger and more valuable.

Good Improvement: Paint Exterior and Interior
Cost: $100 to $1,000
If the paint on the front of your house is peeling, scrape it and repaint. Indoors, cover up any blemishes and repaint any rooms in loud colors that may be off-putting to others.

Good Improvement: Tidy the Yard
Cost: $100 to $300
No need to break the bank here. Mow the lawn, weed the flowerbeds and pull any dying bushes. Plant flowers in bare spots.

Good Improvement: Replace Hardware
Cost: $300
It's a mistake to replace the kitchen cabinets or closet doors. But you can convince buyers to pay a little more by installing new handles, knobs and drawer pulls where needed.

Good Improvement: Replace Ugly Appliance
Cost: $500 to $1000
A new stainless steel range will not prompt buyers to pay much more for your home. But a seriously bedraggled stove or refrigerator could scare them off. If you've got a junky-looking appliance, swap it out for a budget-minded replacement.

Good Improvement: Steel Entry Door
Cost: Around $1,170
A heavy entry door comes with an impressive return: You're likely to get back your investment plus a 29% gain, according to the National Association of Realtors remodeling 2009 report.

Good Improvement: Roofing Credit
Cost: $19,700
If your roof leaks, offer the buyer a discount. It's likely to cost you less than the difference between what it'll cost you to replace the roof before selling and the lesser amount you'll recoup afterward. Source: National Association of Realtors/Remodeling.

Bad Improvement: Family Room Addition
Cost: $82,800
If you're itching to add a family room, do it for your family. Do not do it to profit from selling your home; you're likely to be disappointed. Source: National Association of Realtors/Remodeling.

The oil damaged shoreline in the Northern reaches of Barataria Bay is seen amidst work boats in oil polluted waters as Louisiana Gov. Bobby Jindal's t AP – The oil damaged shoreline in the Northern reaches of Barataria Bay is seen amidst work boats in oil polluted …

NEW ORLEANS – It is an overlooked danger in the oil spill crisis: The crude gushing from the well contains vast amounts of natural gas that could pose a serious threat to the Gulf of Mexico's fragile ecosystem.

The oil emanating from the seafloor contains about 40 percent methane, compared with about 5 percent found in typical oil deposits, said John Kessler, a Texas A&M University oceanographer who is studying the impact of methane from the spill.

That means huge quantities of methane have entered the Gulf, scientists say, potentially suffocating marine life and creating "dead zones" where oxygen is so depleted that nothing lives.

"This is the most vigorous methane eruption in modern human history," Kessler said.

Methane is a colorless, odorless and flammable substance that is a major component in the natural gas used to heat people's homes. Petroleum engineers typically burn off excess gas attached to crude before the oil is shipped off to the refinery. That's exactly what BP has done as it has captured more than 7.5 million gallons of crude from the breached well.

A BP spokesman said the company was burning about 30 million cubic feet of natural gas daily from the source of the leak, adding up to about 450 million cubic feet since the containment effort started 15 days ago. That's enough gas to heat about 450,000 homes for four days.

But that figure does not account for gas that eluded containment efforts and wound up in the water, leaving behind huge amounts of methane. Scientists are still trying to measure how much has escaped into the water and how it may damage the Gulf and it creatures.

The dangerous gas has played an important role throughout the disaster and response. A bubble of methane is believed to have burst up from the seafloor and ignited the rig explosion. Methane crystals also clogged a four-story containment box that engineers earlier tried to place on top of the breached well.

Now it is being looked at as an environmental concern.

The small microbes that live in the sea have been feeding on the oil and natural gas in the water and are consuming larger quantities of oxygen, which they need to digest food. As they draw more oxygen from the water, it creates two problems. When oxygen levels drop low enough, the breakdown of oil grinds to a halt; and as it is depleted in the water, most life can't be sustained.


The National Science Foundation funded research on methane in the Gulf amid concerns about the depths of the oil plume and questions what role natural gas was playing in keeping the oil below the surface, said David Garrison, a program director in the federal agency who specializes in biological oceanography.

"This has the potential to harm the ecosystem in ways that we don't know," Garrison said. "It's a complex problem."

BP CEO Tony Hayward on Thursday told Congress members that he was "so devastated with this accident," "deeply sorry" and "so distraught."

But he also testified that he was out of the loop on decisions at the well and disclaimed knowledge of any of the myriad problems on and under the Deepwater Horizon rig before the deadly explosion. BP was leasing the rig the Deepwater Horizon that exploded April 20, killing 11 workers and triggering the environmental disaster.

"BP blew it," said Rep. Bart Stupak, D-Mich., chairman of the House investigations panel that held the hearing. "You cut corners to save money and time."

In early June, a research team led by Samantha Joye of the Institute of Undersea Research and Technology at the University of Georgia investigated a 15-mile-long plume drifting southwest from the leak site. They said they found methane concentrations up to 10,000 times higher than normal, and oxygen levels depleted by 40 percent or more.

The scientists found that some parts of the plume had oxygen concentrations just shy of the level that tips ocean waters into the category of "dead zone" — a region uninhabitable to fish, crabs, shrimp and other marine creatures.

Kessler has encountered similar findings. Since he began his on-site research on Saturday, he said he has already found oxygen depletions of between 2 percent and 30 percent in waters 1,000 feet deep.

Shallow waters are normally more susceptible to oxygen depletion. Because it is being found in such deep waters, both Kessler and Joye do not know what is causing the depletion and what the impact could be in the long- or short-term.

In an e-mail, Joye called her findings "the most bizarre looking oxygen profiles I have ever seen anywhere."

Representatives of the National Oceanic and Atmospheric Administration acknowledged that so much methane in the water could draw down oxygen levels and slow the breakdown of oil in the Gulf, but cautioned that research was still under way to understand the ramifications.

"We haven't seen any long-term changes or trends at this point," said Robert Haddad, chief of the agency's assessment and restoration division.

Haddad said early efforts to monitor the spill had focused largely on the more toxic components of oil. However, as new data comes in, he said NOAA and other federal agencies will get a more accurate read on methane concentrations and the effects.

"The question is what's going on in the deeper, colder parts of the ocean," he said. "Are the (methane) concentrations going to overcome the amount of available oxygen? We want to make sure we're not overloading the system."

BP spokesman Mark Proegler disputed Joye's suggestion that the Gulf's deep waters contain large amounts of methane, noting that water samples taken by BP and federal agencies have shown minimal underwater oil outside the spill's vicinity.

"The gas that escapes, what we don't flare, goes up to the surface and is gone," he said.

Steven DiMarco, an oceanographer at Texas A&M University who has studied a long-known "dead zone" in the Gulf, said one example of marine life that could be affected by low oxygen levels in deeper waters would be giant squid — the food of choice for the endangered sperm whale population. Squid live primarily in deep water, and would be disrupted by lower oxygen levels, DiMarco said.

Meanwhile, the Coast Guard signaled a shift in strategy Friday to fight the oil, saying it was ramping up efforts to capture the crude closer to shore.

Coast Guard Adm. Thad Allen said an estimated 2,000 private boats in the so-called "vessels of opportunity" program will be more closely linked through a tighter command and control structure to direct them to locations less than 50 miles offshore to skim the oil. Allen, the point man for the federal response to the spill, previously had said surface containment efforts would be concentrated much farther offshore.
