In many cases, the end of the year gives you time to step back and take stock of the last 12 months. This is when many of us take a hard look at what worked and what did not, complete performance reviews, and formulate plans for the coming year. For me, it is all of those things plus a time when I u...
High Altitude Pseudo Satellites (HAPS) offer exciting capabilities
and operational flexibility for earth observation,
telecommunications, and navigation. These aircraft are
lightweight, autonomous, and designed to operate for multiple
weeks or even months at altitudes of approximately 20 km. Unmanned
Aerial Vehicles (UAVs), HAPS, and satellites can be enabled by
solar technology, but shouldn’t that technology be designed
specifically for each of these? Innovative HAPS designs need
innovative power technology. To maintain continuous operations,
HAPS require a renewable energy solution that is lightweight,
powerful, robust, and specially tailored for the unique demands of
The right solar technology can meet this challenge and can be
applied to a wing or curved surface to provide autonomous power
for extended periods. It is high efficiency, lightweight, thin,
and flexible. This technology will also withstand the stresses of
UV radiation and temperature variations at stratospheric
Devices will discuss the issues faced by HAPS and how the
right solar technology can meet these demands.
Aarohi Vijh - Head of Product, Alta Devices Recent
advances in solar technology are enabling HAPS. In this poster
presentation, thin-film gallium-arsenide solar cells designed
specifically to power autonomous systems and manufactured by Alta
Devices, will be discussed. The potential of this technology will
be examined in the context of power-to-weight, durability, and
ease of application. Some of the unique issues faced in the HAPS
environment will also be considered.
Innovative HAPS, UAV, small satellite, and automotive designs need
solar power to match. Lightweight, thin, and flexible
gallium-arsenide solar cells from Alta Devices enable designs that
are not possible with other solar technologies. Alta cells provide a
new level of mechanical and design flexibility for the unmanned
systems industry due to their high power-density combined with the
ability to bend around curved surfaces. Alta Devices is the
world-record holder for single junction solar cell efficiency at
29.1%. The newest generation product from Alta demonstrates a
significant weight reduction from the previous version resulting in
an improved power-to-weight ratio.
About Alta Devices:Alta
Devices is empowering autonomy by delivering the world’s most
efficient, thin and flexible mobile power technology. By converting
light of any kind into electricity, Alta Devices AnyLight™ power
technology extends the energy source of a system, and in many cases,
completely cuts the traditional power cord. The solution can be
completely integrated into the final system, and is ideal for use in
automotive, unmanned systems, satellites, consumer electronics, sensors

Modern software design has fundamentally changed how we manage applications, causing many to turn to containers as the new virtual machine for resource management. As container adoption grows beyond stateless applications to stateful workloads, the need for persistent storage is founda...
"NetApp's vision is how we help organizations manage data - delivering the right data in the right place, in the right time, to the people who need it, and doing it agnostic to what the platform is," explained Josh Atwell, Developer Advocate for NetApp, in this SYS-CON.tv interview at ...
The Jevons Paradox suggests that when technological advances increase efficiency of a resource, it results in an overall increase in consumption. Writing on the increased use of coal as a result of technological improvements, 19th-century economist William Stanley Jevons found that the...

Skeuomorphism usually means retaining existing design cues in something new that doesn’t actually need them. However, the concept of skeuomorphism can be thought of as relating more broadly to applying existing patterns to new technologies that, in fact, cry out for new approaches.
In his session at 20th Cloud Expo, Scott Davis, CTO of Embotics, discussed how automation can provide the dynamic management required to cost-effectively deliver microservices and container solutions at scale. He also discussed how flexible automation is the key to effectively bridging...
