Cornerstone Sustainable Energy Announces Engine Demonstrations

Qualified clients can now be offered demonstrations of CSE's engine technology.

NEW YORK, April 15, 2015 -- Receivable Acquisition &

Management Corporation (OTCQB:CSEI) d/b/a Cornerstone Sustainable Energy
("CSE"), an energy technology company offering Cleantech energy solutions
for the Waste Heat to Energy and Geothermal markets, announces that it has
established a testing facility and development lab space in New York for the
purpose of refining the operating parameters of its current PwrCor(TM)
thermal hydraulic engine.Qualified clients can now be offered demonstrations of CSE's engine

CSE has installed a demonstration engine in the facility and has been
exercising its capabilities for several weeks. The engine has been operating
successfully at full capacity with input heat at its design specification of
180degreesF, and these results have prompted initial testing at even lower
operating temperatures.

CSE's PwrCor(TM) engine operates economically using temperatures and flows
that competitive technologies cannot match. The technology is designed to
generate power with lower grade heat and with significantly less thermal
inflow than any technology on the market. As a result, these engines are
useful in a wide range of applications which, until the present, have been
entirely impractical and often not possible.
Engine applications include electrical generation, water purification or
desalination, fluid pumping, and gas compression.

The engine is entirely "green," operating simply from sources of heat and
cold. It requires no combustion from fossil or bio fuels, thus having no
emissions, and operates relatively quietly.

The engines are engineered to be modular and scalable, which easily enables
manufacturing of different sized engines.

CSE is now capable of providing, for delivery or testing, an engine designed
to generate 10kWe. This configuration is readily expandable up to at least
80kWe. CSE intends to offer larger engine options, using a different
configuration, which are specified to generate between 125kWe and 500kWe.
All engines are skid-mounted with modest footprints.
