A satellite would be the right path. If LENR is scaleable, then houses, cars, water heaters, desalination, space stations, boats, trains, HVAC, electricity generation and aircraft would eventually all experience the economic disruption.
A water heater/boiler for a small building would be a great start for a real world test.
Assuming you can fly a plane with LENR you should be able to dispense with a good number of satellites.
