First Tellurium completes thermoelectric module testing

FTEL · Price

Executive Summary

  • First Tellurium Corp.'s subsidiary, PyroDelta Energy, has successfully completed testing of thermoelectric modules designed to extend the range of high-payload combustion drones.
  • The modules utilize heat differentials from engine exhaust to charge onboard batteries, replacing heavy magneto assemblies and resulting in an 80% weight reduction.
  • CEO Tyrone Docherty highlighted significant insider buying, noting the purchase of over 650,000 shares in September, while stating the company is now presenting the device to industry and defense manufacturers.

Key Details

  • Technology Function: The thermoelectric modules attach to engine exhaust manifolds, using heat differentials to charge batteries that power the drone's on-board electronics.
  • Performance Metrics:
    • Weight Savings: The PyroDelta unit weighs 1 pound compared to conventional magnetos which weigh approximately 5 pounds (80% weight reduction).
    • Efficiency: Eliminates the mechanical strain on the engine caused by rotating magneto mass, thereby increasing horsepower output and fuel efficiency/range.
  • Testing Conditions: Extensive testing was conducted with a drone manufacturer, including:
    • Operation in vacuum chambers to simulate high altitudes.
    • Exposure to heat and sand to simulate harsh desert environments.
  • Commercial Status: R&D and testing phases are complete; PyroDelta is currently presenting the device to manufacturers supplying high-payload drones to industry and North American defense departments.
  • Insider Activity: CEO Tyrone Docherty reported personally purchasing over 650,000 shares in September, with his family continuing to increase their positions.
  • Share Price Context: Docherty attributed recent share price stagnation to selling pressure from a single fund, contrasting it with interest from other funding groups.

Notable Quotes

  • Michael Abdelmaseh (PyroDelta Head Engineer): "These modules are very compact and lightweight... Not only do you have a weight savings of 80 per cent... the drone engine no longer has to rotate all the mass of a magneto. This strain limits horsepower output. As a result, our modules will increase performance and how far a drone can travel on a tank of fuel."
  • Tyrone Docherty (President and CEO, First Tellurium): "This is just one reason why I continue to support and invest in First Tellurium... I assure you the lack of movement in the share price does not reflect the attention we're getting from other funding groups who have followed development of PyroDelta's technology."
