Eight Objectives of the Lawrenceville Plasma Physics Focus Fusion Experiments
This site has described how the Mr. Fusion scenario would change the world.
They have achieved one of eight experimental goals so far. The eight goals and the timeline they are working on as listed at FocusFusion.org.
By the End of 2009
* At 25kV (kilovolts): Produce 1 MA (million amperes), determine optimum gas pressure
Get the experimental machine to function at 25 kilovolts, the lowest planned experimental voltage, and to produce more than 1 Million Amps of current. They will also very shortly switch over to running with deuterium and thus achieve their first fusion reactions with FF-1. In achieving this goal, they will also determine the optimum gas pressure for this current.
* Test theory of axial magnetic field
The third goal is to test the theory that adding a small axial magnetic field, and thus a small amount of angular momentum, to the plasma will greatly increase the size of the plasmoids and thus the efficiency of energy transfer into the plasmoid.
* Move to 45kV, 2MA, with Deuterium
The fourth goal is to increase the charging potential on the machine, by 5 kV steps, up to the full capacity of 45 kV and in the process achieve a peak current of about 2 MA with deuterium.
* Confirm University of Texas Dense Plasma Fusion results, with better instruments
The fifth goal is to confirm the Texas results of high temperature and density, but with far more complete diagnostic instruments.
By end of 2010
* Heavier Gases: D + He + N, and shorter electrodes
The sixth goal is to confirm LPP’s theory that heavier gases will lead to higher compression and to thereby achieve gigagauss fields. This will involve running with combination of D (deteurium), He (Helium) and perhaps N (Nitrogen) and will also involve replacing the electrode with shorter ones, which they predict will be optimized for the heavier gases. These experiments are more complex and will be more time-consuming.
* pB11
The seventh goal is to demonstrate some fusion burn with pB11 (proton-boron) fuel.
* Net energy
The eighth and final goal will be to demonstrate the scientific feasibly of producing net energy with pB11.
First Goal Achieving a Pinch, Has Been Done. Why it Matters
From Focus Fusion, Eric Lerner summarizes the significance of first shots and pinch as follows:
The achievement of a pinch, and on the second shot, means that we have accomplished one of the eight technical goals of the current experimental program. The machine is doing what we designed it to do, which is to transfer energy into a tiny plasmoid. It is quite unusual for a DPF to pinch right way. Normally fine-tuning of the electrodes and insulator and “conditioning” of the electrodes by several shots is required. That this was not needed is confirmation that our electrode and insulator dimensions, derived from LPP’s quantitative theory of DPF functioning, are accurate.
Tweaking of the Experimental System to Setup for Firing/Shots
The “down time” the crew has been experiencing stems from various components in the machine which prevent the “shot” from going off as it should. The whole machine, in a sense, has to be fine tuned to eliminate leaks and losses and bring the charge to bear along the electrodes with the correct timing, and keep the gas in the vacuum.
Various components such as the vacuum, switches, triggers and so forth have been assembled, disassembled, tweaked, re-assembled.
Consider the vacuum chamber. It has many vulnerable points – there are “windows” for observation and connecting diagnostic instruments. Each connection point represents some vulnerability. Every time they change something, they have to test the vacuum again. There’s a big table in the room with FoFu, covered with tools. I visit the lab, and the guys are in there, switching out a rogowski coil from the drift tube, for example. Re-connecting it. Testing the vacuum again. This is why the machine was designed as it is, with access to walk in under the machine and constantly take things off and add things on.
Intel and Sun Micro Product Roadmap Updates
* Intel will show off “Westmere,” the first processors built using a 32 nanometer (nm) manufacturing process.
* CPU manufacturing shrank from 65nm to 45nm to 32nm and next to 22nm.
* The next chip architecture will come in 2010, in the form of the new architecture codenamed “Sandy Bridge,” which will also be disclosed at this month’s IDF. Intel’s roadmap is process shrinkage and then better architecture and then process shrink etc… (tick-tock)
* This new-generation high-k metal gate transistor formula will give Intel “a 3+ year advantage in addressing leaky and energy inefficient transistors,” according to a blog post from Intel spokesman Bill Kircos Intel has shipped >200 million 45nm CPUs using high-k+ metal gate transistors.
* For the first time, Intel has developed a full-featured SoC process technology to complement the CPU-specific technology. This version is for our smarter System on Chip (SoC) product efforts, which emphasize lower power transistors
* Intel NMOS transistors now have 19% performance improvement over their 45nm counterparts and our PMOS transistors now have a 28% performance improvement over their 45nm counterparts.
* Another IDF highlight: Nehalem-based chips codenamed “Jasper Forest” and designed for the embedded and storage sectors. This family of products will bring Nehalem to the embedded market, offering integrated PCI Express (PCIe) and an integrated I/O hub in a dual-processor Xeon processor.
* Nehalem will allow for much faster and denser storage and communications solutions such as IPTV, VoIP, NAS, SAN and wireless radio network controllers
The UK Register has information on the Sun Sparc Roadmap. The 16-core “Rock” UltraSparc-RK processor for Sun’s once-and-never “Supernova” line of servers is not on the roadmap. The one-page roadmap is one given Sun’s customers – and presumably also Fujitsu’s customers – have been shown about the future Sparc processor lineup.
A long way off in late 2010 or early 2011, the Sparc Enterprise server lineup gets a speed boost to 3 GHz with the Jupiter-E chips.
After that, in 2012, Sun has made no commitment to the kicker line of Fujitsu “Advanced Product Line 2″ servers coming from Fujitsu. These APL2 machines are presumably to be based on the “Venus” eight-core Sparc64-VIII processor, which has a Sparc64-VIIIfx variant aimed at supercomputers. That Sparc64-VIIIfx chip will be used in a 10 petaflops massively parallel machine being built by Fujitsu and paid for by the Japanese government under the 1.2bn Project Keisoku effort.
All of this is subject to change, and some of it most certainly will once Oracle takes control of Sun.
Agriculture and Science Hero Norman Borlaug has Died
More than 30 years ago, Borlaug wrote, “One of the greatest threats to mankind today is that the world may be choked by an explosively pervading but well camouflaged bureaucracy.” As REASON’s interview with him shows, he still believes that environmental activists and their allies in international agencies are a threat to progress on global food security. Barring such interference, he is confident that agricultural research, including biotechnology, will be able to boost crop production to meet the demand for food in a world of 8 billion or so, the projected population in 2025.
Borlaug was the Father of the Green Revolution, the dramatic improvement in agricultural productivity that swept the globe in the 1960s. For spearheading this achievement, he was awarded the Nobel Peace Prize in 1970.
In the late 1960s, most experts were speaking of imminent global famines in which billions would perish. “The battle to feed all of humanity is over,” biologist Paul Ehrlich famously wrote in his 1968 bestseller The Population Bomb. “In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now.” Ehrlich also said, “I have yet to meet anyone familiar with the situation who thinks India will be self-sufficient in food by 1971.” He insisted that “India couldn’t possibly feed two hundred million more people by 1980.”
But Borlaug and his team were already engaged in the kind of crash program that Ehrlich declared wouldn’t work. Their dwarf wheat varieties resisted a wide spectrum of plant pests and diseases and produced two to three times more grain than the traditional varieties. In 1965, they had begun a massive campaign to ship the miracle wheat to Pakistan and India and teach local farmers how to cultivate it properly. By 1968, when Ehrlich’s book appeared, the U.S. Agency for International Development had already hailed Borlaug’s achievement as a “Green Revolution.”
In Pakistan, wheat yields rose from 4.6 million tons in 1965 to 8.4 million in 1970. In India, they rose from 12.3 million tons to 20 million. And the yields continue to increase. Last year, India harvested a record 73.5 million tons of wheat, up 11.5 percent from 1998. Since Ehrlich’s dire predictions in 1968, India’s population has more than doubled, its wheat production has more than tripled, and its economy has grown nine-fold
The Atlantic also profiled Borlaug in 1997.
Borlaug has never received much public recognition in the United States, where it is often said that the young lack heroes to look up to. One reason is that Borlaug’s deeds are done in nations remote from the media spotlight: the Western press covers tragedy and strife in poor countries, but has little to say about progress there. Another reason is that Borlaug’s mission — to cause the environment to produce significantly more food — has come to be seen, at least by some securely affluent commentators, as perhaps better left undone. More food sustains human population growth, which they see as antithetical to the natural world
By the 1980s finding fault with high-yield agriculture had become fashionable. Environmentalists began to tell the Ford and Rockefeller Foundations and Western governments that high-yield techniques would despoil the developing world.
Environmental lobbyists persuaded the Ford Foundation and the World Bank to back off from most African agriculture projects. The Rockefeller Foundation largely backed away too — though it might have in any case, because it was shifting toward an emphasis on biotechnological agricultural research. “World Bank fear of green political pressure in Washington became the single biggest obstacle to feeding Africa,” Borlaug says.
Borlaug’s reaction to the campaign was anger. He says, “Some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They’ve never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels. If they lived just one month amid the misery of the developing world, as I have for fifty years, they’d be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things.”
Borlaug, Carter, and Sasakawa traveled to Africa to pick sites, and the foundation Sasakawa-Global 2000 was born. “I assumed we’d do a few years of research first,” Borlaug says, “but after I saw the terrible circumstances there, I said, ‘Let’s just start growing.’” Soon Borlaug was running projects in Benin, Ethiopia, Ghana, Nigeria, Sudan, Tanzania, and Togo. Yields of corn quickly tripled; yields of wheat, cassava, sorghum, and cow peas also grew.
Borlaug made progress even in Sudan, near the dry Sahel, though that project ended with the onset of Sudan’s civil war, in 1992. Only Sasakawa’s foundation came forward with more funds, but although well endowed, it is no World Bank. Environmentalists continued to say that chemical fertilizers would cause an ecological calamity in Africa.
Opponents of high-yield agriculture “took the numbers for water pollution caused by fertilizer runoff in the United States and applied them to Africa, which is totally fallacious,” David Seckler says. “Chemical-fertilizer use in Africa is so tiny you could increase application for decades before causing the environmental side effects we see here. Meanwhile, Africa is ruining its wildlife habitat with slash-and-burn farming, which many commentators romanticize because it is indigenous.”
From the 1997 Atlantic article: rice yields 1.6 tons per acre in China
1997 Agriculture Yields
Privatization and dwarf rice have enabled China to raise rice yields rapidly to about 1.6 tons per acre — close to the world’s best figure of two tons.Lester Brown, the head of the Worldwatch Institute, an environmental organization, fears that China may soon turn from an agricultural success story into a nation of shortages
2008
Rice plants have been greatly improved over the last three decades. Plant breeders have created plants that mature in 110 days instead 160 which means that regions with warm climates can grow three crops instead of two. The height of the average plant has been reduced from five feet to a stocky three feet, which means that the plant nutrient go into producing grains of rice and are not “wasted” on the stalks that lean over when there is too much weight. In addition, rice plants have been bred and bio-engineered to be resistant to bacterial blight, plant hoppers and stem borders.Tall conventional rice plant used before 1968 grew in 140-180 days and yielded between 0.6 and 1.4 tons per acre. Modern rice grows in 110-140 days, produces 100 seeds per panicle, and yields between 2.4 and 4.0 tons per acre.
2020 Agriculture
By the year 2020 it is believed the world’s rice crop will increase by an additional 60 percent. Current dwarf varieties have 15 productive panicles, or seed clusters per stalk (out 25 or so total stalks) that produce about 100 grains (seeds) each. New strains will have fewer, but stronger and thicker, stalks that will yield 200 or more grains each. These new plants are expected to account for most of the increased productivity
There is a project to re-engineer photosynthesis in rice to increase yields
There is work to enable plants to survive on the moon and Mars. Success or anywhere close to success will also mean plants that can grow in deserts on earth.
Technology and economic growth has been occuring in Africa and looks promising.
Offtopic: Entertainment Briefs
No word yet if this reboot will bring the FF into the same movie continuity shared by Iron Man, the Hulk and Nick Fury, as has been established in the “tags” following Iron Man and The Incredible Hulk.
This is good as the Fantastic Four movies desperately need to be rebooted.
There rumors that Doctor Who will meet Blackadder.
It would be good if this happens. Doctor Who should meet Blackadder, Mr Bean and Dr House. The actor, Hugh Laurie, in House appeared in Blackadder. The Blackadder actor, Rowan Atkinson, played Blackadders and Mr Bean. Just one throw away episode.
Aubrey de Grey now calls Actuarial Escape Velocity, the Methuselarity
A recent issue of Studies in Health Technology and Informatics includes a number of interesting papers on longevity science, or that relate to developing the tools and research community to enable engineered longevity. You might start with an essay by Aubrey de Grey, in which he coins a new term for an aspect what has in the past been called actuarial escape velocity – the point at which steadily increasing life expectancy rises by more than one year with each passing year:
Aging, being a composite of innumerable types of molecular and cellular decay, will be defeated incrementally. I have for some time predicted that this succession of advances will feature a threshold, which I here christen the ‘Methuselarity,’ following which there will actually be a progressive decline in the rate of improvement in our anti-aging technology that is required to prevent a rise in our risk of death from age-related causes as we become chronologically older. Various commentators have observed the similarity of this prediction to that made by Good, Vinge, Kurzweil and others concerning technology in general (and, in particular, computer technology), which they have termed the ‘singularity.’ In this essay I compare and contrast these two concepts.
At present, life expectancy is increasing at about one year for every five years that pass – only 20% of what is needed to keep our expected remaining years of life increasing at the same speed with which we age. That said, it is worth remembering that life expectancy is a statistical construct based on past data – it is a helpful measure of progress, but not necessarily an indication of where we are now. I suspect it lags present medical advances, for example, because their effects on mortality rate might not show up for a decade or more.
