u 3D-Printed
Lubrication System
Effective lubrica tion is essential
to any mechanical sys -
tem. For example, it is responsible
for providing a continuous
flow of oil to the engine of the
aircraft. As aircrafts have
evolved, so have lubrication
systems. A Florida-based startup
Zulu Pods has developed the ZPod, a self-contained,
sealed, oil tank and pump that can be installed
into existing low-cost expendable jet engines.
The ZPod is small enough to fit in the palm of a
hand and is produced with 3D printing. The technology
promises to revolutionize lubrication systems
design for single-use engines like those found
in drones and missiles. In addition to its use in expendable
jet engines, ZPods can be used in helicopters
as a lifesaving lubrication reservoir system. This
emergency lubrication system significantly extends
flight times in loss-of-lubrication events.

u Renewable
Energy Storage
Technology
A Dutch-based startup
Ocean Grazer has
developed an inventive way to store offshore renewable
energy where it is produced: offshore. The
" Ocean Battery " is a very large energy-storage system
designed to capture excess power from floating
wind farms. With a combination of pumps, flexible
bladders, and rigid reservoirs, the Ocean Grazer
team took a tried-and-true energy concept - the
hydrodam - and brought it to the sea. Excess power
from nearby windfarms is routed to the battery,
which is installed deep into the ocean floor. The
battery pumps freshwater from the stiff underground
reservoirs to a bladder just above the seabed.
When there is a demand for power, the water,
pressurized naturally from the sea, is routed back
through hydroturbines to generate electricity.

CEO Dr. Frits Bliek.
This column presents technologies that have
applications in commercial areas, possibly
creating the products of tomorrow. To learn
more about how each technology was ideated,

u Aerodynamic Luge Sleds
Engineering improvements in luge design are difficult to make because of complicated
aerodynamics, complex sled geometry and unsteady, turbulent air flow
around the sled. Traditionally, lugers design and build their own sleds, often
through trial and error. Now, Clarkson Mechanical and Aeronautical Engineering
Professors Doug Bohl and Brian Helenbrook, in collaboration with Colby Mazzuca
of Aeroworks, are using advanced computational and experimental methods to
optimize sled geometries for developing faster, more aerodynamic sleds. A computational
method called adjoint-based optimization helps find optimal shapes for luge design to improve performance,
such as improving lift or reducing drag. The research will have applications beyond luge in other industries
to optimize the design of vehicles like cars, trucks, ships, and advanced air vehicles.
