They have cleaned the Tungsten. There was a lot of non-trivial engineering needed.
LPP fusion is working out theoretically ways to transfer more of the energy from the electron beam to the heating of plasmoid, leaving less available to damage the anode. This work involves mixing in heavier gases and is still under way. We’ll report more on it next month. Reassembly of the cleaned electrodes is now almost complete. LPP Fusion expects new experiments in early September.
In late August, LPPFusion sold the last shares from its fourth stock offering, completing the raising of $2 million in capital. The share offering was initiated in June, 2011 when 20,000 shares were offered at $100 a share. During the four years of this offering, LPPFusion also sold out a fifth special offering for $250,000, and raised $180,000 through its Indiegogo crowdfunding effort. Over these years, the rate of funding has increased, with total funds raised per year doubling for the period since January 2014 as compared with the prior period.
The LPPFusion Board of Advisors will soon decide on the terms of a new stock offering to fund the company on an expanded scale in the coming years. In accordance with US SEC regulations, shares will only be available to US citizens and to those living in the US who qualify as “accredited investors”, and will be available to all others in accordance with regulations in their countries.
A 50-100 fold reduction in impurities is required from the Tungsten electrode. 5-10 times less impurity than that has been achieved in tests in the summer.
Eventually they want to reach a goal of about 30 shots per week.
Delays with the Tungsten electrode have put LPP Fusion 7 months behind the planned 2015 schedule
LPP Fusion published their scheduled plans for 2015
LPP Fusion Plans for 2015:
As in previous years we emphasize that our plans require adequate financing. They also depend on critical suppliers coming through on time and within specifications. However we are confident that the tungsten cathode will arrive soon, and we are planning a backup monolithic copper cathode as well. Our main goal for this year remains to increase the density of the plasmoid, the tiny ball of plasma where reactions take place, the third and last condition needed to achieve net energy production.
January-March: Now September-October
1. We will complete our computer upgrade and the creation of our Processed Data Base, a powerful
tool for analyzing our data.
2. We will install our new tungsten electrode and perform experiments that we expect will
a) Increase density about 100-fold to around 40 milligrams/ cm³
b) Increase yield more than 100- fold to above 15 J
c) Demonstrate the effect of the axial field coil
d) Demonstrate the positive effects of mixing in somewhat heavier gases, such as nitrogen
April-June: now probably November
1. Move to shorter electrodes
December, 2015 - Early 2016
1. Implement our improved connections and demonstrate peak currents above 2 MA
2. Increase density to over 0.1 grams/cm³
October-December - only if they can run experiments in parallel but likely Q1 or Q2 of 2016
1. Move to beryllium electrodes, or at least beryllium anode, which will be needed as x-ray emission increases so much that tungsten electrodes would be cracked by the heat absorbed. Beryllium is far more transparent to x-rays.
2. Demonstrate density over 1 gram/ cm³
3. Demonstrate billion-Gauss magnetic fields
4. Demonstrate the quantum magnetic field effect with these billion-Gauss magnetic fields; show its ability to prevent plasmoid cooling caused by x-rays, making possible the net energy burning of pB11 fuel.
5. Install new equipment and begin running with pB11 mixes
Summary of Lawrenceville Plasma Physics
LPP needed to get their Tungsten electrode and then later switch to a berrylium electrode.
If successful with their research and then commercialization they will achieve commercial nuclear fusion at the cost of $400,000-1 million for a 5 megawatt generator that would produce power for about 0.3 cents per kwh instead of 6 cents per kwh for coal and natural gas.
LPP’s mission is the development of a new environmentally safe, clean, cheap and unlimited energy source based on hydrogen-boron fusion and the dense plasma focus device, a combination we call Focus Fusion.
This work was initially funded by NASA’s Jet Propulsion Laboratory and is now backed by over forty private investors including the Abell Foundation of Baltimore. LPP’s patented technology and peer-reviewed science are guiding the design of this technology for this virtually unlimited source of clean energy that can be significantly cheaper than any other energy sources currently in use. Non-exclusive licenses to government agencies and manufacturing partners will aim to ensure rapid adoption of Focus Fusion generators as the primary source of electrical power worldwide.
