Advanced Concepts: LENR, Anti-Matter, and New Physics of the Nuclear and Emerging Technologies for Space conference
Cold Fusion Now h/t Next Big Future
quote ( Ruby Carat of CFN)
Sounds exciting. Especially the BECNF ( Bose Einsten Condensates) stuff by Y E Kim.

On Friday, March 23 I attended Session 462 Advanced Concepts: LENR, Anti-Matter, and New Physics of the Nuclear and Emerging Technologies for Space conference, one day after speaking with George H. Miley who would be presenting A Game-Changing Power Source for Spacecraft at the session.

What if?
One of the problems with space travel is the need for matter where there is little and the need for energy, which exists in abundance, but not in a convenient form.
Obviously, you don't want to carry matter with you which imposes a mass penalty during the escape from the deep gravity well of the Earth. So, the trick is to get the matter you need up there and use it over and over again.
Moreover, the propulsion necessary for travel will have to come from an energy source of some kind and a matter source for reaction mass. Since the matter you need is scarce- since it is after all, outer space- which is empty, you will need a way to get matter for propulsion without having to go deep into a gravity well.
So, here is the proposition: Make a solar panel large enough to provide energy for propulsion and it will also be powerful enough to recycle matter an endless number of times.
Such a large panel require a large structure, and there may be a way to accommodate that.
If you are going to be in space, you will need some type of artificial gravity. In order to have an artificial gravity of 1g, it will entail a structure that is 1000 meters in diameter. Such a structure could provide also for a large solar panel to be installed on top of it. Once spun up, it will provide the gravity, plus all the energy that you can possibly use and then some.
The sun provides about 1300 watts per square meter. Given the size of the structure, the amount of electricity that could be generated would be about 1 gigawatt at 30% percent efficiency. One gigawatt is more than enough electricity to power a VASIMR towards Mars on a fast trajectory.
Solar panels need not weigh that much, thus the mass of the panels would not be too prohibitive. Matter might be obtained from asteroids and an occasional foray onto the Moon or Mars. Perhaps a LOXLEO design could be implemented which could be powered from the solar panels from Earth orbit and collect gases from the upper atmosphere.
Getting the structure up into space could be the bigger challenge, since it is not clear at this time how that may be done. If it is to be done at all, it must be modular in design and be lifted and constructed piecewise until the structure is complete. It should be obvious that this would require a lot of launches and missions.
Therefore, a cost effective way of getting out of the deep gravity well of the Earth must be found first.
This may be possible if a launch system like Stratolaunch is successful. If not Stratolaunch, some other way may be found.

The Limitless Potential of the E-Cat: An Interview with Andrea Rossi
OilPrice.com
quote:
A unusually interesting answer:
quote:
Some of the questions we asked Mr. Rossi take a look at:
• Why it took so long for him to go public with his discovery.
• How the E-Cat will produce energy costing $10/megawatt hour.
• When he will release more detailed information on the E-Cat.
• Why he believes international media coverage of the E-Cat has been so muted.
• His feelings towards critics and the scientific community.
• His manufacturing and distribution goals.
• How the E-cat will help reduce mankind’s dependency on fossil fuels.
• + Many more details on the e-cat, LENR and Rossi himself.
A unusually interesting answer:
Andrea Rossi: Yes, of course I questioned my discovery. It was hard to believe that I had finally produced a working example of LENR. I paid Sergio Focardi, the physicist and emeritus professor at the University of Bologna, to try and convince me that I was wrong, and relieve me of my obsession with LENR. In the end I ended up convincing him, and he decided to work with me in developing the E-Cat machine. [emphasis added]
Cold Fusion Now: Rossi E-cat a Bargain compared to Nuclear
March 12, 2012 / Brad Arnold h/t pesn
Rossi made the following comment on his blog:
Dear Dr Joseph Fine:
- In a 45 MW plant, if Siemens gives us 30% of efficiency, the COP is not 6, is infinite: the energy to drive the resistances will be made by the E-Cat: if we make 45 thermal MWh/h, 15 electric MWh/h will be made, of which 7.5 will be consumed by the plant, 7.5 will be sold, together with30 thermal MWh/h.
- The price of a 45 MW plant will be in the order of 30 millions.
- the price of the energy made by our industrial plants will be made by the owners and by the market.
Warm Regards,
A.R

Musk seems deeply disappointed that his heroes from the Apollo Era, Neil Armstrong and others, were not supportive of his efforts.
