System Details

System Benefits: Environment

We believe that new transportation solutions must address environmental issues head-on. That’s why Skai uses hydrogen fuel cells – the cleanest practical end-to-end fuel system on the planet.

Transportation is a significant producer of pollution and contributes to climate change – in the US, it accounts for the largest portion of total emissions (28%). And while most vehicles run cleaner today than in the past, there are more vehicles than ever that are being used more often, offsetting the benefits of increased efficiency and regulations. Aviation and automobiles are responsible for a significant share of the world’s harmful emissions. In the US, road vehicles account for 83% of total greenhouse gas emissions, with aircraft accounting for 9%.

One of Skai’s primary goals is to ultimately reduce greenhouse emissions and other pollutants by replacing a large number of road vehicles and short-haul aircraft with quiet, pollution-free, minimal-impact air mobility.

System Benefits: Commuting

Skai has the power to improve life for everyone, every day. Perhaps the clearest and most relatable benefit is a dramatic improvement to commuting. Americans, on average, spend 42 minutes a day commuting – in cities like Los Angeles or Dallas, that number is nearly double.

According to recent studies, the combined cost of traffic congestion in terms of lost productivity and wasted fuel is more than $100 billion annually. In addition, millions of vehicles sitting in traffic every day emit pollution, affecting the environment and human health. There is also a psychological cost associated with commuting, from the obvious increase in stress, to road rage, to a feeling of helplessness.

Skai offers an alternative. Multi-hour commutes down to just minutes. Pollution-free operation. A pleasant, comfortable experience. And once the system is up to scale, services that are affordable for everyone.

Production Efficiency

The history of General Aviation over the past 25 years has seen a steady decline in the number of aircraft produced each year, which leads to lower volumes for critical components such as engines and avionics, and corresponding higher prices.

Skai takes a different approach. By focusing on a safe, simple, reliable vehicle, we apply automotive manufacturing techniques and scale, to produce tens of thousands of vehicles each year. Our manufacturing partner is working closely with us to lower costs and increase production rates. All key factors that help to increase end-user affordability and utilization in markets never before served by air vehicles – to deliver on the promise of reduced pollution and improved quality of life.

Application: SkaiCab

A key application for Skai will be providing point-to-any-point travel for the general public. This can include everything from affordable, everyday air-pooling to work, a weekend trip to the beach, or inter-city business travel.

The SkaiCab configuration features seating for up to 5 and an easy and user-friendly passenger experience. A intuitive app, familiar to any ride-share user, will allow users to hail a Skai vehicle in their area, input their destination and style of travel (sharing the ride via air-pooling or reserving the entire vehicle).

Once Skai production is at scale, the cost for air-pooling should be competitive with or cheaper than current road-based ride-share services. Reserving an entire vehicle will be more expensive than air-pooling, but significantly less costly than current helicopter and fixed-wing air-taxi prices.

Application: SkaiMed

The SkaiMed configuration is designed for first responder, EMS and medivac services. Its advantages are clear – it’s an ambulance that can go anywhere, from anywhere. SkaiMed has the ability to land closer to patients and access areas road-based ambulances and helicopters can’t get to. In addition, Skai’s quiet, low RPM rotors and minimal rotor wash (air turbulence) allow it to operate in densely populated areas.

In a medical emergency, every moment counts, and Skai’s high availability and efficient performance means that patients will get the care they need more quickly. When the vehicle is en route to the hospital, Skai’s IRIS avionics can transmit real-time patient data to both the emergency room and to the doctor’s smartphone via telemetry.

Application: SkaiCargo

SkaiCargo is a freight service application, offering a payload capability of up to 1000 lbs. It will typically operate on feeder routes – routes off of the main cargo hubs that require smaller vehicles. In the SkaiCargo configuration, interior tie-downs or floor tracks are used to secure payload. There is a single seat for the pilot, or no seat at all, in the case of a ground-control pilot or fully autonomous operation.

With the increasing popularity of online shopping, there are more feeder route trucks on the roads. They not only add to traffic congestion, but also emit harmful emissions. SkaiCargo can help relieve this additional stress on busy roadways with its clean, quiet, low-impact performance.


Skai’s infrastructure is safe and simple, in part because there’s not much to it – no airport, landing pads or other facilities to build. Skai can take off and land from existing locations, like parking lots, rooftops – really anywhere with about 500 square feet of space.

Fueling stations are outdoors as a safety precaution. In case of a leak, extremely light, non-toxic hydrogen gas will quickly and safely dissipate into the air. (In fact, hydrogen’s buoyancy means that it will ultimately escape the earth’s atmosphere into space). Smart fuel pumps “talk” to the vehicle to ensure the system checks out before pumping. Refueling takes less than 10 minutes, allowing up to 4 hours of continuous flight.

Ground control systems monitor every Skai vehicle in the area, with the ability to assist or intervene if there’s a problem. For example, in the event that a pilot loses consciousness, the vehicle can be safely flown by a ground-based pilot. In the event that the encrypted tactical data link to the ground pilot fails, the vehicle can safely RTB (return to base) or land nearby, fully autonomously. Note that Skai is autonomous-ready today, but FAA regulations do not currently allow its use.
