VivaSpire builds lightweight oxygen generating machines that refill themselves from the air around them. Rather than compressing air, the device can bind oxygen with the use of a nanomaterial. The oxygen is concentrated and can then be rapidly released from the device by changing temperature. We’ve already made a device that captured oxygen from the air (21%) and released it at 77%. The device weighed only 0.941kg (2lbs) and could last 3 hours before needing to recharge the batteries.
We aim to allow humankind to thrive in polluted climates, at higher altitudes, underwater, and on Mars. In these situations, it’s not practical to store and transport bottled oxygen (due to its weight, operational lifetime, and size).
