# Liquid-Nitrogen Cooling Systems Green Kinoko Introduced Kinsho Outdoor Cooler By Colin Smith | Written with AI assistance | Published 2026-04-07 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/kinsho-outdoor-cooler References: [newatlas](https://newatlas.com/lifestyle/green-kinoko-nitrogen-outdoor-cooling/)  Israeli startup [Green Kinoko](https://www.trendhunter.com/trends/green-kinoko-kensho) introduced the Kinsho, a [portable outdoor cooling system](https://www.trendhunter.com/trends/chillpill) that uses liquid nitrogen to chill seating areas without electricity. The units run by releasing liquid nitrogen, which expands into gas and drives a mechanical engine to blow nitrogen at about −10 °C, providing cold air without mains power. Green Kinoko built 12 prototypes and planned public pilot trials at a large Tel Aviv café, with tanks replaced every 7–10 days depending on use. The company said tanks cost roughly €50–60 and noted nitrogen is commonly produced as a byproduct of medical oxygen manufacturing; larger-scale production and supply logistics were cited as next steps. For venues and events, Kinsho promises a [quiet, mobile alternative to outdoor AC](https://www.trendhunter.com/trends/ecoflow-wave-3) that avoids dumping heat elsewhere and reduces electricity demand where adopted. Safety handling and sourcing low‑carbon nitrogen remain practical considerations for operators evaluating the system.
