Current Fossil Fuel Heating System Complexity

  • Fossil fuel extraction challenges
    • Buried >1 kilometer underground
    • Located in inconvenient places: Arctic Circle, conflict zones, ocean floor
    • Formation requires 60-600 million years from dead plankton
  • Complex distribution infrastructure
    • Deep drilling operations
    • Global transportation: pipes, trucks, tankers to refineries
    • Refineries: expensive industrial facilities sorting hydrocarbon molecules
    • Underground pipeline network: millions of miles long ("invisible interstate highway")
    • Entire steel mills built solely for pipeline production
  • Safety monitoring and risks
    • "Smart pigs" robots inspect pipelines for defects ("pigging the pipeline")
    • 2010 San Bruno pipeline explosion: 8 deaths, 1,000-foot wall of fire
    • 2018 Massachusetts pipeline explosions: 1 death, 50,000 evacuated
  • Alternative fuel delivery challenges
    • Fuel oil and propane lack pipeline infrastructure
    • Tens of thousands of trucks deliver door-to-door
    • Fuel stored in basement/yard tanks
  • Health hazards
    • Carbon monoxide detectors required for all heating fuels
    • Hundreds of Americans die annually from heating system poisoning

Geothermal Energy Solution

  • Ground-based thermal energy source
    • Consistent temperature few feet underground
    • Examples: caves and wine cellars maintain stable temperatures
    • Vast renewable energy reservoir beneath every building
  • System components
    • Ground loops: simple plastic pipes buried under yard
    • Heat pump: installed inside home (typically replacing furnace)
    • Ground loops last as long as home itself
  • Growing adoption trend
    • More homeowners choosing geothermal over fuel-based options
    • Permanent switch from fossil heating

Company Solution and New Utility Model

  • Streamlined geothermal installation service
    • Online form completion by homeowners
    • Custom geothermal system design
    • Installation using purpose-built tools and equipment
  • Distributed utility concept
    • Homes exchanging renewable energy with ground
    • Simple, local, inexpensive operation
    • Permanent wholesale shift from fossil fuels
  • Environmental benefits
    • Avoid Arctic Circle and seafloor destruction
    • Bypass refineries and pipelines
    • Eliminate family poisoning risks
    • Utilize existing energy beneath every building
