What specific problem are you solving?
In the construction industry, traditional brazing and heating processes rely on hazardous fossil-fuel gases like acetylene and propane, posing significant safety risks and environmental concerns. These methods are bulky, and inefficient, raising operational costs and contributing to substantial carbon emissions. The reliance on such fuels complicates logistics, increases the carbon footprint, and hinders sustainability efforts, presenting a pressing need for safer and more eco-friendly solutions in building construction practices.
What is your solution?
Green Flames introduces a cutting-edge oxyhydrogen gas generator that transforms brazing and heating in the construction and HVAC sectors. Our machine uses water electrolysis to produce clean-burning oxyhydrogen gas, eliminating the need for hazardous and costly fuels like acetylene or propane. Requiring only water and electricity, it simplifies logistics and slashes operational costs. Its built-in safety systems—pressure control, gas flow regulation, and flame supervision—ensure reliable and secure performance across diverse job sites. Environmentally, the system generates zero carbon emissions, with water vapor as the sole byproduct. This supports sustainability goals and helps companies meet strict environmental regulations. Economically, using water as a fuel source significantly lowers costs and reduces downtime from fuel deliveries and maintenance, boosting overall site productivity. Portable and easy to deploy, the Green Flames machine suits both indoor and remote outdoor applications, offering clean-air operation and independence from traditional gas supply chains. Green Flames offers a smart, sustainable, and safe alternative for modern construction needs—enhancing workplace safety, cutting costs, and contributing to a greener future.
Who does your solution serve, and in what ways will the solution impact their lives?
Green Flames primarily serves technicians, small workshop owners, and construction contractors in the HVAC and metalworking industries—groups that often face high costs, safety risks, and logistical challenges associated with traditional fuel-based welding systems like oxy-acetylene. These users are typically underserved due to limited access to affordable, safe, and eco-friendly alternatives. Fuel gas cylinders are costly, difficult to transport, and pose fire and explosion risks, especially in densely populated or remote areas with limited supply chains. Green Flames addresses these challenges by providing a compact, portable welding machine that generates oxyhydrogen gas on-demand using just water and electricity. This eliminates the need for hazardous gas storage, significantly reduces operating costs, and improves on-site safety. Our technology also levels the playing field by simplifying the welding process, making it easier for new or less-experienced technicians to achieve high-quality results without years of training. This empowers more individuals to enter the trade and enhances productivity for small businesses and contractors. By reducing financial and operational barriers, Green Flames meaningfully improves working conditions, economic opportunity, and health outcomes for workers, while helping businesses meet rising environmental standards and sustainability goals.
