More Science Talk
Welcome to the Scientific American podcast Science Talk, posted on February 13, 2013. I’m Steve Mirsky. On this episode: “Now is the time to reach a level of research and development not seen since the height of the Space Race.” That’s the president, of course. In his 2013 State of the Union address, Pres. Obama talked about climate change, energy and manufacturing technology innovation, and STEM education—that is, science, technology, engineering and math. Here are the approximately 12 minutes of the speech that dealt with those subjects:
“Our first priority is making America a magnet for new jobs and manufacturing. After shedding jobs for more than 10 years, our manufacturers have added about 500,000 jobs over the past three. Caterpillar is bringing jobs back from Japan. Ford is bringing jobs back from Mexico. And this year, Apple will start making Macs in America again.
“There are things we can do, right now, to accelerate this trend. Last year, we created our first manufacturing innovation institute in Youngstown, Ohio. A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the 3-D printing that has the potential to revolutionize the way we make almost everything. There’s no reason this can’t happen in other towns.
“So tonight, I’m announcing the launch of three more of these manufacturing hubs, where businesses will partner with the Department of Defense and Energy to turn regions left behind by globalization into global centers of high-tech jobs. And I ask this Congress to help create a network of 15 of these hubs and guarantee that the next revolution in manufacturing is made right here in America. We can get that done.
“Now, if we want to make the best products, we also have to invest in the best ideas. Every dollar we invested to map the human genome returned $140 to our economy—every dollar. Today, our scientists are mapping the human brain to unlock the answers to Alzheimer’s. They’re developing drugs to regenerate damaged organs; devising new material to make batteries 10 times more powerful. Now is not the time to gut these job-creating investments in science and innovation. Now is the time to reach a level of research and development not seen since the height of the Space Race. We need to make those investments.
“Today, no area holds more promise than our investments in American energy. After years of talking about it, we’re finally poised to control our own energy future. We produce more oil at home than we have in 15 years. We have doubled the distance our cars will go on a gallon of gas, and the amount of renewable energy we generate from sources like wind and solar—with tens of thousands of good American jobs to show for it. We produce more natural gas than ever before—and nearly everyone’s energy bill is lower because of it. And over the last four years, our emissions of the dangerous carbon pollution that threatens our planet have actually fallen.
“But for the sake of our children and our future, we must do more to combat climate change. Now, it’s true that no single event makes a trend. But the fact is the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, floods—all are now more frequent and more intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science—and act before it’s too late.
“Now, the good news is we can make meaningful progress on this issue while driving strong economic growth. I urge this Congress to get together, pursue a bipartisan, market-based solution to climate change, like the one John McCain and Joe Lieberman worked on together a few years ago. But if Congress won’t act soon to protect future generations, I will. I will direct my Cabinet to come up with executive actions we can take, now and in the future, to reduce pollution, prepare our communities for the consequences of climate change, and speed the transition to more sustainable sources of energy.
“Four years ago, other countries dominated the clean energy market and the jobs that came with it. And we’ve begun to change that. Last year, wind energy added nearly half of all new power capacity in America. So let’s generate even more. Solar energy gets cheaper by the year—let’s drive down costs even further. As long as countries like China keep going all in on clean energy, so must we.
“Now, in the meantime, the natural gas boom has led to cleaner power and greater energy independence. We need to encourage that. And that’s why my administration will keep cutting red tape and speeding up new oil and gas permits. That’s got to be part of an all-of-the-above plan. But I also want to work with this Congress to encourage the research and technology that helps natural gas burn even cleaner and protects our air and our water.
“In fact, much of our new-found energy is drawn from lands and waters that we, the public, own together. So tonight, I propose we use some of our oil and gas revenues to fund an Energy Security Trust that will drive new research and technology to shift our cars and trucks off oil for good. If a nonpartisan coalition of CEOs and retired generals and admirals can get behind this idea, then so can we. Let’s take their advice and free our families and businesses from the painful spikes in gas prices we’ve put up with for far too long.
“I’m also issuing a new goal for America: Let’s cut in half the energy wasted by our homes and businesses over the next 20 years. We'll work with the states to do it. Those states with the best ideas to create jobs and lower energy bills by constructing more efficient buildings will receive federal support to help make that happen.
“America’s energy sector is just one part of an aging infrastructure badly in need of repair. Ask any CEO where they’d rather locate and hire—a country with deteriorating roads and bridges, or one with high-speed rail and Internet; high-tech schools, self-healing power grids. The CEO of Siemens America—a company that brought hundreds of new jobs to North Carolina -- said that if we upgrade our infrastructure, they’ll bring even more jobs. And that’s the attitude of a lot of companies all around the world…”
“These initiatives in manufacturing, energy, infrastructure, housing—all these things will help entrepreneurs and small business owners expand and create new jobs. But none of it will matter unless we also equip our citizens with the skills and training to fill those jobs. And that has to start at the earliest possible age.
“Study after study shows that the sooner a child begins learning, the better he or she does down the road. But today, fewer than 3 in 10 four year-olds are enrolled in a high-quality preschool program. Most middle-class parents can’t afford a few hundred bucks a week for a private preschool. And for poor kids who need help the most, this lack of access to preschool education can shadow them for the rest of their lives. So tonight, I propose working with states to make high-quality preschool available to every single child in America. That's something we should be able to do.
“Every dollar we invest in high-quality early childhood education can save more than seven dollars later on—by boosting graduation rates, reducing teen pregnancy, even reducing violent crime. In states that make it a priority to educate our youngest children, like Georgia or Oklahoma, studies show students grow up more likely to read and do math at grade level, graduate high school, hold a job, form more stable families of their own. We know this works. So let’s do what works and make sure none of our children start the race of life already behind. Let’s give our kids that chance.
“Let’s also make sure that a high school diploma puts our kids on a path to a good job. Right now, countries like Germany focus on graduating their high school students with the equivalent of a technical degree from one of our community colleges. So those German kids, they're ready for a job when they graduate high school. They've been trained for the jobs that are there. Now at schools like P-Tech in Brooklyn, a collaboration between New York Public Schools and City University of New York and IBM, students will graduate with a high school diploma and an associate's degree in computers or engineering. We need to give every American student opportunities like this.
“And four years ago, we started Race to the Top—a competition that convinced almost every state to develop smarter curricula and higher standards, all for about 1 percent of what we spend on education each year. Tonight, I’m announcing a new challenge to redesign America’s high schools so they better equip graduates for the demands of a high-tech economy. And we’ll reward schools that develop new partnerships with colleges and employers, and create classes that focus on science, technology, engineering and math—the skills today’s employers are looking for to fill the jobs that are there right now and will be there in the future.”

Add CommentI believe that he means that he wants to get more energy from it, like getting the most from a dollar.
Reply | Report Abuse | Link to thisHe said "make it burn even cleaner". Meaning he acknowledges it's clean, but could it be cleaner? Yes.
Reply | Report Abuse | Link to thisI don't know what most people use natural gas for, but I use it to heat my living room, water heater, and cook my food. Not sure it could be any more efficient.
Very inspiring speech, full of optimism, identifying the programs ahead with remarkable clarity, touching every facet of American life.
Reply | Report Abuse | Link to thisNatural gas is only "clean" relative to replacing old coal fired power plants. At best it is short term drop in carbon emissions relative to current levels based on high use of dirty coal. But as ALL climate scientists say, if we burn more than 20% of all this new natural gas we're finding, the game is over.
Reply | Report Abuse | Link to thisAn all of the above short term strategy may be necessary to appease the climate deniers, but if we don't get a carbon neutral strategy in place there is no hope of avoiding catastrophic climate change.
Yes. I am sure President Barack Obama has ambitious plants to tackle Climate change and for massive Green Energy usage. Already US is pioneer in Wind and Solar. One area where US has vast scope is offshore wind farms.
Reply | Report Abuse | Link to thisAssessment of Offshore Wind Energy Resources for the United States Marc Schwartz, Donna Heimiller, Steve Haymes, and Walt Musial,National Renewable Energy Laboratory, Technical Report NREL/TP-500-45889 June 2010 states:
“In May 2008, the U.S. Department of Energy (DOE) released a report detailing a deployment scenario by which the United States could achieve 20% of its electric energy supply from wind energy (U.S. Department of Energy 2008). Under this scenario,offshore wind was an essential contributor, providing 54 gigawatts of installed electric capacity to the grid. When President Obama took office in January 2009, his message clearly reinforced this challenge in a broader context of energy independence,environmental stewardship, and a strengthened economy based on clean renewable energy sources. To achieve the deployment levels described in the 20% wind report, many technical and economic challenges must be faced. Many coastal areas in the United States have large electricity demand but have limited access to a high-quality land-based wind resource,and these areas are typically limited in their access to interstate grid transmission.Offshore wind resources have the potential to be a significant domestic renewable energy source for coastal electricity loads. The development of a reference and validated
offshore wind resource database is one of the first steps necessary to understand the magnitude of the resource and to plan the distribution and development of future offshore wind power facilities”.
There is vast scope to set up offshore wind farms in US.

Record drought in the US farm belt in 2012 summer withered corn fields and parched hopes for a record US corn harvest, but US farmers may not be the ones most severely affected by the disaster. Most have insurance against crop failure. Not so the world's import-dependent developing countries, nor their poorest consumers. They are hurting.
Reply | Report Abuse | Link to thisThis is the third food price spike in the last five years, and this time the finger is being pointed squarely at biofuels. More specifically, the loss of a quarter or more of the projected US corn harvest has prompted urgent calls for reform in that country's corn ethanol programme.
Domestically, livestock producers dependent on corn for feed have led demands for change in the US Renewable Fuel Standard (RFS), which mandates that a rising volume of fuel come from renewable sources. Up to now that has been overwhelmingly corn-based ethanol.
Corn is probably the most problematic feedstock for biofuels. In many parts of the world it is grown as food for human consumption, serving as the staple grain for some one billion people worldwide. It is also a key feed for livestock, giving it another direct link to the human food supply through meat, dairy and egg prices.
In this debate Food Vs Fuel, fortunately we have Alternate sources for Biofuel production. Agave is a care-free growth plant. Biofuel is extracted from this. Mexico is pioneer in this. Oxford University study on agave-to-ethanol: http://pubs.rsc.org/en/content/articlelanding/2011/ee/c1ee01107c
The results are awesome!:
"[...] the emissions of agave-derived fuel are estimated to stand at around 35g of CO2 per megajoule from field-to-wheel, compared to the 85g/MJ emitted when making corn ethanol."
Dr Tan and his colleagues found this energy balance is five units to one.
"This compares favourably to the highly efficient sugarcane, and to the less efficient corn as a source of biofuel. It also compares favourably to sugarcane-derived ethanol for its ability to offset greenhouse gas emissions, which we calculated at 7.5 tons of CO2e per hectare per year - taking into account the crop's complete lifecycle"
Agave's higher yield (65 annual tonnes of dry biomass per hectare per year, from year 3 on) and higher-quality of its lignocellulosic fibres make it the best feedstock on Earth for liquid biofuels production:
On an annual basis, one hectare of agave yields up to ten times the solid sugars of one hectare of sugarcane in Brazil, meaning ten times more ethanol/biofuels per hectare per year!

The main drawback for wider application of Biofuels is input. There was a big movement for biofuel from Jatropha in India but in reality not much has been achieved. Agave(Americana),Sisal Agave is a multiple use plant which has 10% fermentable sugars and rich in cellulose. The fibre is used in rope making and also for weaving clothes in Philippines under the trade name DIP-DRY. In Brazil a paper factory runs on sisal as input. A Steroid HECOGENIN is extracted from this plant leaves. Since on putrification,it produces methane gas, it can be cut and used as input in biogas plants. Also in Kenya and Lesotho dried pieces of Agave are mixed with concrete since it has fibres which act as binding.

Agave shows potential as biofuel feedstock, Checkbiotech, By Anna Austin, February 11, 2010:
“Mounting interest in agave as a biofuel feedstock could jump-start the Mexican biofuels industry, according to agave expert Arturo Valez Jimenez.
Agave thrives in Mexico and is traditionally used to produce liquors such as tequila. It has a rosette of thick fleshy leaves, each of which usually end in a sharp point with a spiny
margin. Commonly mistaken for cacti, the agave plant is actually closely related to the lily and amaryllis families. The plants use water and soil more efficiently than any other plant or tree in the world, Arturo said. “This is a scientific fact—they don’t require watering or fertilizing and they can absorb carbon dioxide during the night,” he said. The plants annually produce up to 500 metric tons of biomass per hectare, he added.
Agave fibers contain 65 percent to 78 percent cellulose, according to Jimenez. “With new technology, it is possible to breakdown over 90 percent of the cellulose and hemicellulose structures, which will increase ethanol and other liquid biofuels from lignocellulosic biomass drastically,” he said. “Mascoma is assessing such technology.”
Agave can be grown in waste lands in developing countries.
Another option is OPUNTIA,care-free growth plant. Biogas can be mass produced and then power generation. China has Biogas Generators upto MW size commercially available.
Agave is a CAM Plant.As the CO2 content of the air progressively declined millions of years ago, certain plants evolved specialized biochemical pathways and anatomical adaptations that enabled them to increase their intracellular CO2 concentration at the site of its fixation, which allowed the primary carboxylating enzyme rubisco to function more efficiently. The CO2 concentrating mechanism possessed by these CAM plants operates by sequentially reducing CO2 into carbohydrates at two different times of day. The initial reduction of CO2 into a four-carbon sugar is done at night - when CAM plant stomata are open - by the enzyme PEP-carboxylase. Then, during the day when CAM plant stomata are closed, the four-carbon sugar is decarboxylated, increasing the plant's intercellular CO2 concentration, and the resulting CO2 is subsequently reduced back into a carbohydrate, but this time by rubisco.
