CORNERSTONE WATER
PROPULSION INNOVATION
Our propulsion was built
ground-up to be low-cost,
efficient, low risk, safe, easy to
refuel, reusable and scalable.
The use of Microwave
Electrothermal ("MET")
technology is the cornerstone
that makes all our current
services possible
Throttleable
. Can vary thrust and ISP
to optimize the trip time
Uses water as a propellant
• Safe
• Easy to test
• Available in space
High ISP
• 2 to 5 times any chemical propulsion system
• Efficient maneuvers in space

MICROWAVE ELECTROTHERMAL
(MET) TECHNOLOGY
Scaleable
• Larger engines are even more efficient
and have higher ISP
Simple design uses off-the-shelf
components
• Low cost during manufacture
• Low risk when making new design
Inlet
High thrust
• 10 times higher than most electric propulsion
• Results in faster trip times
