Plasma Simulation Advances

Simulation-220.06-ns

Another simulation LPPFusion is working on is modeling the early stages of the current sheath within the plasma. This original simulation software is being developed by LPPFusion Simulations Researcher Dr. Warwick Dumas. It differs from the most common plasma simulations, called MHD, in accurately distinguishing the way electrons and ions behave when they are moving…

Major Software Upgrades Aid Thermal, Mechanical Simulations

LPP Fusion LOGO

Our CIO, Ivy Karamitsos, carried out a major IT upgrade thanks to the Wefunder crowdfunding investments that we gained this March. The upgrade cost just under $40K, but it was a long overdue investment into our infrastructure as we needed improved in-house capabilities for our engineering drawing software and simulation productions. We also purchased SolidWorks…

ICCD Video Reveals Shocks

Animation-230-to-1100-ns-with-Gray-Arrows

A full sequence of images of the current sheath of LPPFusion’s FF-2B experimental device shows that a shock wave is the most likely proximate cause of the disruption of filaments that has limited fusion energy yield. Our rapidly-advancing effort to provide new switches for FF-2B provides a path to eliminating the oscillations that cause these…

Lerner to Speak on Energy, Finance and Coronavirus—Online May 17

Eric Lerner will be speaking Sunday, May 17 at an online Teach-in on the Coronavirus: Causes, Impact and Our Response. He will be speaking on “Energy, Finance and the Coronavirus”. The presentation will explain how fossil fuel use contributed to the pandemic. It will also show how the collapse of oil prices in March motivated…

Beryllium Decreases Electrode Erosion

Beryllium-Anode-Erosion

While the cracks were bad news, our inspection of the beryllium anode also brought good news. The erosion of the electrode near the insulator has markedly decreased with the beryllium electrode as compared with our previous tungsten electrode. This erosion and roughening, seen clearly in Figure 3a of our last tungsten anode caused an asymmetric…

Anode Cracks; Another Design on The Way

Syed-and-Eric-Removing-Anode

Just as the LPPFusion research team was about to resume firing in March, we discovered that FF-2B’s anode was cracked. We’ve used the shutdown time, necessitated by both the crack and the coronavirus, to complete the design of our new switches, and to redesign the anode. We’re aiming to resume firing with these crucial new…

FF-2B Recovers from Minor Accident

Be with Vacuum Chamber

While we would love to cheer our readers with some exciting news form the lab, this past month we have been held up by a minor accident and our (mostly successful) efforts to recover from it. On Jan. 20, at 4:00 AM, on a holiday, our lab suffered a brief power outage. Although all our…

Our Plan to Get to Net…Energy

Focus Fusion Generator – CAD Drawing

During the Wefunder campaign, people have asked us: how can we expect to go rapidly from where we are to net energy—when we get more energy out of the device than we put in? We gave them an explanation. Since many people have told us how useful this information is, we are featuring it in…

Wefunder Campaign Ends—Over $600,000 Raised

LPPFusion Card lifted1

Thanks to all of you for a second successful Wefunder campaign. We raised $605,000 from 292 investors living in 22 countries. All 133 slots for new non-accredited investors were filled. For accredited investors, we will be continuing fundraising directly through our website. During the campaign, which began Nov.15, 2019 and ended March 1, 2020, we…
