IMHO this is far better, and more effective than solely abstinence training. http://www.medicalnewstoday.com/articles/86051.php King School children will need permission from a parent to attend the health centre. However, under state law, the health centre is required to keep the treatment confidential, which means parents will not know whether their children are getting contraceptive pills.

I have seen the Moons of Jupiter and Saturn, as well as the rings with just binoculars. I have seen all the major bands of Jupiter with my 90mm refractor bought new for 150 dollars, 8 yrs ago. $200 buys you a brand new computerized telescope with 4k object database.

I think its extremely likely that Polywell fusion will work. If the current research proves out this summer, then its looks we will get 200 million bucks from Uncle Sam, then over 3 to 5 yrs the program will work on proof of concept. Then in 4 to 7 yrs we may see the first standard designs worked up. A lot of "ifs", but never the less in 15 years we would be seeing 1000mw Bussard Fusion Reactor (BFR) production ramped up to commercial levels. At 20 yrs we would see the launching of Polywells off Earth and to the Moon, to power Lunar bases, or stations in orbit. As well as Fusion powered space craft capable of making runs to Mars or Saturn and Jupiter. Fusion will give us the Solar System.

Sorry, at 50kv to 65kv of drive voltage. pB-11 fusion happens at 1eV. The probability is very low. The cross section at 60 KeV center of mass (CoM) is 1E-5 barns. Dr. B. detected significant D-D fusion at 20 KeV CoM at which the cross section was 1E-2 barns. pB-11 has a similar cross section at around 130 KeV CoM. Which is a drive voltage of about 50 KV. http://fti.neep.wisc.edu/iec/operat1.gif University of Wisconsin chart, but does not show P-B11.

I dont know. I do know that theory says a proton and a B11 need 50 to 65 KeV acceleration to fuse. I'm guessing that 580 KeV is enough to make many things fuse. I think you are describing a very strong polywell type potential well ? 2005 WB-6 test results using DD fuel: 1) 5.0kV , 800A B-field, 1 neutron count 2) 9.8kV , 750A B-field, 2 neutron counts 3) 12.5kV , 700A B-field, 2 neutron counts 4) 12.5kV , 800A B-field 3 neutron counts SOURCE DISCUSSION WB-6 Polywell magnets circa October 2005. Single coil Mag field cross section. Polywell Magnetic fields. In the center there is a 4 pointed dark spot, that is the potential well, an area dense with electrons. There is no need to hold a virtual cathode in place. Though Farnsworth's original work on the fusor is much like the picture Jacques posted. http://en.wikipedia.org/wiki/Fusor http://www.damninteresting.com/?p=163 http://www.youtube.com/watch?v=eeMd5LCu7Ag&feature=related Recently some have built Farnsworth type Fusors for just a few thousand US dollars In a Polywell....The ions form a virtual anode. The electrons form a virtual cathode. This is vacume tube science. From the perspective of being in the center of the Polywell magnets you are looking at the "MGrid" or Whiffle ball: http://www.busybeaks.com/images/wiffle.jpg One would be inside the Whiffle Ball looking out at the faces of the magnetic fields. Lets feed the magnets some current, increasing the potential well strength. Now lets introduce the electrons, they will collect in the center due to the potential well, as if they are being pushed there by the magnetic fields. They push back at the MGrid. If one introduces a fuel ion inside the cage of the MGrid, the ion sees the electrons gathered at the potential well and races towards it. This is the virtual cathode.

Polywell fusion uses DD fuels, hopefully soon to be PB-11. Heres a slightly inaccurate picture. The fuel you fuse dictates what the products will be. PB-11 Fusion would be aneutronic but create radioactivity, Dueterium fusion creates lots of neutrons but no fission style radioatctivity. Yes. Yes Very likely. Dr Gerald Kulcinski of the U of Wis and Apollo Astronaut Harrison Schmidt are 2 big advocates of He fusion. Kulcinski uses Inertial Electrostatic Confinement to fuse He. Kulcinski and his IEC fusion device. In operation. Meanwhile the late DR Bussard had developed his Polywell Fusion device, and completed Dueterium fusion test runs before his recent death. His work contines under DR Nebel, formerly of Livermore. Polywell may be able to fuse Boron11, using the Proton, Boron collision. Dueterium and Tritium fusion creates neutrons, which degrade the materials in the fusion reactor and can hurt humans. IIRC He and Boron are aneutronic fusion, no, or nearly no neutrons. Therein lies the advantages of these 2 fuels. Dr Bussards WB-6 Polywell in operation in 2005. Polywell fusion relies on accelerating 2 particles fast enough, so that when they collide, they fuse. Heres a brief showing electrons forming a potential well inside the magnetic grid ( McGrid). Ions are introduced inside the MCGrid, they see the potential well and are attracted to it, at high speed. Dr Nebel. formerly of Livermore, is running the current Polywell program in Santa Fe, Recently his WB-7 device saw 1st plasma. A device the same size, but more powerful, would be capable of test runs generating 50Kev to 65Kev acceleration, where the PB-11 fusion can occur. Boron 11 fusion would create lots of alpha particles, which would be directly converted to electricity via electrostatic grids. Theory says a 500MW PB-11 net power reactor core would be 3 meters across.

IIRC the 1st law of thermodynamics comes into play here. I prefer get my H2 from water. Electricity does work, its used to get H2 from H20, the 1st law IIRC says you cant get the energy back after doing work. SO you might as well use the electricity in an electric car.

This guy has already fused HE. Dr Gerald Kulcinski of the U of Wis and Apollo Astronaut Harrison Schmidt are 2 big advocates of He fusion.

The only source on earth for He3 comes from decommissioned nuclear weapons.

I believe the Japanese T-60 Tokamak generated net power in 1998, wiki article . Though I have more hope for alternative programs, I no longer think the toridial design (Tokamak) will work. Inertial Electrostatic Confinement fusion has been around for a while. Work by Dr. Kulcinski @ U Wis in IEC fusion and especially the late Dr Bussards iteration of IEC, the Polywell, currently funded by the DOD, is very neat. Polywell wiki.
