Dear Investors of Prime Lightworks,
I am happy to report that the company is continuing operations and making progress through these challenging times. With your support on StartEngine, Prime Lightworks has now raised over $250K from over 500 investors since launching our Regulation Crowdfunding campaign! This has allowed us to complete a round of preliminary prototype thrust measurements (test results are summarized below). I am also pleased to announce that Prime Lightworks has been accepted to Los Angeles Cleantech Incubator (LACI) two-year incubation program!
The results from our recent test campaign indicate A) that our magnetic shielding enclosure around the prototype test electronics is substantially reducing the false positive thrust measurements from magnetic torque interference, and B) our best chance of producing substantial true positive thrust from electromagnetic propulsion is to replace the software defined radio (SDR) transceiver in our prototype test electronics with a radio frequency (RF) scalar network analyzer (SNA). The change will also require switching the operating system and computer card in our prototype test electronics. The rebuild will cost us approximately $10K in parts and will take us 2-3 months to complete this summer. Once we rebuild our prototype test electronics with the new components, we will resume prototype thrust measurements in vacuum in Q3-Q4 2020.
On Friday, June 12, the company filed our Form C-AR Annual Report with the SEC as required per Regulation Crowdfunding. Under the CARES Act, the company has secured grants through the following federal programs:
Economic Injury Disaster Loan (EIDL) - $2K (two full time employees)
Paycheck Protection Program (PPP) - $48K (two full time employees)
We have runway in the bank into August and will continue raising and disbursing funds through our StartEngine campaign to maintain our prototype test operations.
To consolidate our monthly expenses, we have moved out of our warehouse space in Torrance, CA, since our lease has expired, and we are moving into a much larger warehouse where we can sublease space in Vernon, CA. In addition to saving money on rent, this move will put us within five miles of LACI.
Leading up to our recent prototype thrust measurements in vacuum, we were able to increase the thrust sensitivity of our torsion pendulum by over 10x to a thrust-to-displacement ratio of about 5 micronewtons per micron. We also achieved resonant frequency feedback response for the first time in vacuum using our prototype test electronics SDR transceiver, where we were able to measure the resonant frequency of the microwave cavity to within 1 MHz bandwidth. In tests, we measured about 0.2 micronewton of thrust corresponding to about 1 micron displacement of our torsion pendulum. However, reversing the direction of our microwave cavity did not change the direction of the thrust, meaning that the 0.2 micronewton thrust was false positive and due to magnetic torque interference. In order to maximize prototype thrust, we need to achieve resonance with a quality factor of over 1e5, which will require measurement of the microwave cavity resonant frequency to within 100 kHz. This will be possible by replacing our prototype electronics radio card with a microwave network analyzer, which we will complete in 2-3 months this summer. We will then resume prototype thrust measurements with improved resonant frequency feedback response.
To the extent it could help our business plan and fundraising, we are evaluating an expanded prototype strategy that may allow us to achieve prototype test results this year for a zero-emissions CubeSat launch vehicle. Our initial design would be to build a compressed hydrogen (H2) and compressed gas (air) model rocket engine, followed by a hydrogen model rocket launch as proof-of-concept.
