About MayMaan
MayMaan Research, an entity headquartered in Hollywood, Florida, operates within the clean energy technology sector, focusing on reimagining the internal combustion engine. The company was founded in 2014 by Doron Shmueli, who serves as CEO, alongside his father Yehuda Shmueli and brother Eitan Shmueli, who are the CTO and President, respectively. The genesis of the company was Yehuda's long-held passion for developing alternative energy, which began as a garage-based project and evolved into a formal research and development enterprise.
The core of MayMaan's business is its proprietary AquaStroke® engine technology. This system enables a traditional piston engine to operate on a fuel mixture of approximately 70% water and 30% bio-alcohol, such as ethanol or methanol, eliminating the need for gasoline or diesel. The combustion process involves injecting this fuel blend at high pressure into a modified chamber, where the alcohol's ignition turns the water into steam. This steam generation creates additional pressure, which contributes to a high-torque output, particularly at low RPM ranges, while keeping combustion temperatures lower than in conventional engines. This lower operating temperature significantly reduces the formation of harmful emissions like NOx.
MayMaan's financial strategy is centered on research and development, funded by significant investment, including a $30 million Series A round in May 2023 led by WAVE Equity Partners. This capital is directed towards developing higher output engines to enter new market segments. The company's business model is not to become a mass manufacturer of engines but to operate as an intellectual property and technology firm. It pursues a licensing model, forming strategic partnerships with established original equipment manufacturers (OEMs), engine manufacturers, and energy utilities. These partners integrate MayMaan's technology into their existing systems or new products, handling manufacturing and distribution to end-users. Initial market entry has focused on retrofitting existing engines, with a long-term plan for partners to manufacture complete engines based on the AquaStroke design.
The company's primary target market is applications where diesel engines are prevalent, such as electrical generators, heavy machinery, and off-grid power systems. MayMaan has already deployed 35kW generator units for off-grid and commercial backup power. Future applications are envisioned across a wide array of industries, including automotive, heavy equipment, EV charging infrastructure, data centers, and even grid-scale energy generation. The technology's scalability is a key feature, with the potential to be adapted for engines of various sizes, from small generators to large engines for locomotives and cargo ships.
