Israeli startup Green Kinoko introduced the Kinsho, a portable outdoor cooling system 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 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.

Trend Themes
1. Off-grid Cooling - Portable cryogenic chillers enable cooling in locations without reliable electricity, creating potential for decentralized climate control solutions at remote venues.
2. Cryogenic Microclimate Control - Localized −10 °C air delivery for seating areas points to novel, low-ambient-impact approaches to comfort that bypass conventional HVAC footprints.
3. Circular Gas Supply - Repurposing nitrogen byproducts from medical oxygen production highlights opportunities for integrated supply chains that lower carbon intensity and input costs.
Industry Implications
1. Hospitality and Outdoor Events - Event spaces and cafés could adopt quiet, mobile cooling that reduces electricity demand and changes the economics of temporary outdoor comfort.
2. Agriculture and Horticulture - Targeted cryogenic cooling offers a new tool for microclimate management in crop protection and post-harvest preservation without grid reliance.
3. Energy and Industrial Gases - Scaling low‑carbon nitrogen production and logistics introduces disruptive opportunities in supply, storage, and refill service models for cryogenic applications.
