A startup has created a machine that makes gasoline from air, water, and electricity. It's its bet to save the combustion engine

New York startup Aircela unveiled a working machine that turns air, water, and renewable electricity into gasoline.

The synthetic fuel is compatible with existing combustion engines, so vehicles do not need to be modified.

The company says the system is currently small-scale and inefficient, and is aimed at niche or off-grid uses.

Supporters see it as a possible low-carbon fuel option for hard-to-electrify transport and industrial applications.
