Nobel Conference gets at energy
The technology is inspiring vast tracts of photo voltaic cells lapping up the Arizona sunlight, microbes plucked from the guts of termites breaking down wood into energy we can use, engineering artificial plants, even bacteria, to take sunlight and crank out usable energy.
The crisis, however, that prompted this far out yet plausible science is simple.
Our Bivirkninger principle energy supply, fossil fuels, is running out while polluting the sky with carbon dioxide that is almost surely causing the earth to warm, said Steven Chu, a Nobel laureate in physics who leads a California laboratory with an annual budget "4-chlorodehydromethyltestosterone Ireland" of $500 million.
In addition to talking about "büyüme hormonu eczane fiyatı" global warming, Chu spoke about energy where it comes from, how to conserve it and where it ought to come from in the future on Tuesday at the 43rd annual Nobel Conference at Gustavus Adolphus College in St. Peter.
A refrain: Americans are energy gluttons.
If 2,500 calories are needed to support Comprar Levitra one person, then the 350 gigajoules every American uses per year is the equivalent of 100 "energy servants," as Chu puts it. Each Chinese person, on average, has 10 such "servants."
But a middle class existence for everyone is possible, he said. It will take change, technology and a concerted effort on par with the Apollo project.
Biomass is a part of the energy solution, Chu said, though he added that "corn is not the right crop" because its energy cost is between 80 and 90 percent of fossil fuels.
Grasses have more energy, but first they have to be broken down.
Termites have evolved a symbiotic relationship with bacteria that live in their gut. The bacteria, Chu explains, Comprar Gh Jintropin break down the plants into usable energy, taking some and passing the rest to its host.
Researchers, including ones at Chu's Lawrence Berkeley National Laboratory, are using part of a series of grants, totaling at least $750 million, to search the world's termites and other creatures to see how nature uses this hard to reach energy.
And jungle rot is apparently good at eating clothing, making it another candidate.
But what about all this ethanol produced in southern Minnesota?
Corn is a crop of convenience, bred for its food production and should be abandoned when biorefineries can process a crop chosen specifically for fuel purposes, Chu said.
Another incentive for alternative energy is to establish what is commonly called a "carbon tax," a tax on carbon dioxide pollution.
Lawmakers, though, are afraid of consumer retribution over higher energy prices and can't muster the will to establish such a tax. Chu said one of the most important steps people can take to meet the energy crisis is to call legislators and urge them toward progress, of which a carbon tax could be a part.
But while Chu estimates that biomass can supply only up to 10 percent of the global energy demand, solar power has Testosterone Enanthate Liver the potential to supply much more. It would Winstrol 10 take only a fifth of one percent of the world's non farmable land to satisfy energy demands with solar power.
And while such power is available today, the two barriers to cells covering square miles of desert are cost and the lack of long distance transmission times.
While it's not as interesting as bacteria living in termite guts or as fashionable as solar energy, efficiency is something that anyone can do.
Chu said efficiency gains remain the "low hanging fruit" of energy reduction. Much of that involves lobbying lawmakers to enact efficiency rules.
And Americans' quality of life and energy consumption Sustanon 250 Weekly Dosage need not be at odds, he said.
Using a graph that charts those two variables, Chu showed that Europeans and others manage a similar quality of life on much less energy than Americans consume.
