I am a little curious about how an aircraft with a takeoff weight of two tons could carry 100 passengers, though.
Try this version of the article, written by someone who at least appears to know what they are talking about

It makes it clear that a 2-tonne MTOW aircraft is what the current engine is capable of powering, whereas 100 seats (actually "50-100") is a design goal for the longer term.
No mention of turbines, either.
