It is going into research.<br /><br />It is not like committing to building 100 power plants.<br /><br />And look at what we have spent on ITER - about $200 million a year (counting all research) for a technology not expected to work until 2050 - if it ever does.<br /><br />Polywell has gotten a total of $20 million to $25 million for the total life of the Polywell project. Another $2 million to $5 million will give us a yes/no answer for Polywell in two years or less.M.

I would like to believe that our military scientists see a REAL potential to develop the technology.. and aren't using this project to just fund other projects under the guise of R&D.Momma Bearhttps://www.blogger.com/profile/13433521041610590645noreply@blogger.comtag:blogger.com,1999:blog-6911752388384243976.post-28280398309753929132009-04-20T21:19:00.000+01:002009-04-20T21:19:00.000+01:00Loren,

In fact, Farnsworth's original fusor still holds the "world record" for neutron output for any fusor to date. That makes IEC technology as old as tokamak fusion. There's no comparison between the two technologies if your criteria is progress towards breakeven power output. IEC isn't even in the conversation! The JET tokamak reached a <B>verified</B> Q=0.7 in 1997. ITER is targeted to achieve Q=10 for 5-10 minutes for a continuous burning plasma. With IEC you have nothing but continuous anecdotes of "progress" but nothing of substance. <br /><br />You live in a dream world.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6911752388384243976.post-83729257898385880292009-04-20T04:57:00.000+01:002009-04-20T04:57:00.000+01:00Most laser setups deal with a solar sail type setu...Most laser setups deal with a solar sail type setup. This would be great for deep space missions, but for launching, you need lots of thrust for a short period, rather than a small amount for a long period. I suppose a microwave system would work better, but it would reduce launch vehicle mass by allowing just the reaction mass to be carried, not the energy required to generate the thrust. Instead of massive tanks of oxygen and hydrogen(or pick your fuel), you have a less massive tank of water.<br /><br />Tell me, how long are they asking for to build a machine with a practical Q value? How many billions of dollars? And this after how much time and money?<br /><br />Comparing the two seems to be difficult. I can find Q values for the Tokomak, but not for the Polywell. I can find reactions/sec and such for the Polywell, but not for the Tokomak. And I've no clue how to adjust for the distinct differences in operation. Most likely the answer is on a piece of paper at the lab that hasn't been released. I'd say that an approximately 20 year old project with another 5 or so to go holds more promise than a 50 year old project with another 20 years to go.Lorenhttps://www.blogger.com/profile/14843550881990596267noreply@blogger.comtag:blogger.com,1999:blog-6911752388384243976.post-4106923119437142009-04-20T00:58:00.000+01:002009-04-20T00:58:00.000+01:00Loren,

Holy god what the hell are you talking about?????<br /><br />And for your information, unlike Polywell, tokamaks actually DO work. In fact, they're one of the few approaches that has been shown to work. Do me a favor: go research the current world record Q value and then return and inform us. It's ok - most of us already know the answer - but it will be a good learning experience for you.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6911752388384243976.post-55689364390919769462009-04-18T23:14:00.000+01:002009-04-18T23:14:00.000+01:00Wouldn't be the first time for a book about someth...Wouldn't be the first time for a book about something that never worked.<br /><br />Might as well add all those books on the Tokomak and laser devices.
