    AUSTIN, TX, June 20, 2018 /24-7PressRelease/ -- EigenTherm Solar, Inc. is the latest venture from power conversion industry technologist, inventor, holder of dozens of U.S. and foreign patents, and Ideal Power Founder Bill Alexander. EigenTherm Solar is a concentrated solar power company that has introduced a revolutionary solar thermal collector technology – the FlexForm Collector. The global concentrated solar power (CSP) market size was valued at over USD $3.03 billion in 2016 and is anticipated to grow by 12.7 percent by 2025.

"The FlexForm Collector is the culmination of almost four decades of work and is one of my proudest engineering achievements," said Alexander, president and founder of EigenTherm Solar. "It was designed from the start to achieve the lowest possible costs in concentrating and collecting solar thermal energy and while it is an elegantly simple design, it is also highly effective."

The FlexForm Collector's reflector consists of a thin, specular reflective membrane suspended over prepared ground. A linear receiver placed above the reflector optimally absorbs the concentrated sunlight into a heat transfer fluid. Only the receiver moves to track the sun, while the reflector is stationary but changes shape under the influence of a partial vacuum to maintain optimum concentration – hence the name FlexForm. It is a revolutionary, very low-cost and high performance concentrating solar thermal collector for the cost-effective production of utility scale electric power that can deliver power when coupled with proven thermal storage and power block technologies. At scale, EigenTherm Solar expects to be able to deliver electric power at costs significantly lower than fossil fuels, including combined cycle natural gas in the United States.

A zero-maintenance façade garden capable of looking after itself using solar power.

    KITZINGEN, GERMANY, June 20, 2018 /24-7PressRelease/ -- Vertical gardens on exterior walls and façades are an urban solution to increase the sustainability of our city landscapes. Having met during the 2017 DGNB Sustainability Challenge, the experts at BOXOM GmbH and OPVIUS GmbH teamed up to carry out a joint project to attractively combine a façade garden and printed organic photovoltaics (OPV). The two companies developed a lightweight façade garden capable of tending itself based on sophisticated watering and system technology. OPVIUS' semi-transparent OPV modules power the BOXOM façade system, which then supplies the integrated plants with the right amount of water and nutrients needed for growth.

BOXOM's mission is not just to create vertical gardens, but also to develop façade use for sustainable concepts. The light weight and semi-transparency of the organic photovoltaics (OPV) technology makes it an ideal combination option for vertical gardens. Not only do the OPV modules generate a power supply, they also provide shade for the plants, and protect them from drying out. Plants on the south-facing sides in particular are at risk of getting too much sun, and this is where the OPV modules can help.

The pre-tensioned structure, consisting of steel ropes made by Carl Stahl GmbH, serves as the basis for integrating the OPV modules and plants. The elevated plant cords and the OPV modules are both affixed to these vertically tensioned steel ropes. This system is available as a finished product, and can transform unused vertical façades into attractive, sustainable gardens. The combination of OPV and vertical garden unlocks completely new façade solutions – for both restored and new buildings.

The first OPV vertical garden is currently being presented at a technically innovative "Tiny House" created by Merck KGaA. In addition to the OPV, other highly developed Merck materials and products are also integrated into the Tiny House's many different functions, such as voice control, electrochromic windows, and flat OLED TVs.

Niklas Weisel, Managing Director of BOXOM GmbH, had this to say: "Botanic Horizon vertical gardens, using OPVIUS OPV modules, are a safe, easy way of creating gardens anywhere and fulfilling your passion for gardening even in a small space." Hermann Issa, Senior Director Business Development & Sales at OPVIUS GmbH, adds that "particularly in view of discussions surrounding fine dust and nitric oxide, the self-tending plant system can play an important part in helping with air purity and the wellbeing of local residents in densely built-up inner cities. BOXOM GmbH, with its Botanic Horizon products, and OPVIUS GmbH, with its printed OPV technology, are making an energy-neutral contribution to improving urban climate here."

BOXOM was founded in Saxony's Ore Mountains in 2015, and develops and sells complete vertical-garden solutions for façades, interiors (such as offices, canteens, kitchens and living areas), and greenhouses under the Botanic Horizon brand (see and plant cords, a product from the "Plant technology based on textile cords" series"). The systems developed may be installed in walls and ceilings of new buildings or as a retrofit on existing buildings.

The completely unique, patented vertical plant technology based on textile cords enables a wide range of applications which, through the use of supplementary vertical technologies like photovoltaics, solar heat, heat pumps and much more, make life more convenient and comfortable.

A passionate, award-winning adventurer with experience bringing record-breaking projects to fruition, Domjan was the founder and the expedition leader of PlanetSolar – also powered by SunPower solar technology – which became the first boat to sail around the world on solar energy alone in 2012. This September, Domjan will attempt his first world-record flight, reaching 33,000 feet in a SolarStratos prototype plane.

SunPower® Maxeon® solar cells were selected for SolarStratos aircrafts because they are highly efficient, durable, lightweight, and about as thin as a human hair. On the next generation SolarStratos plane, SunPower's 24-percent efficient cells will be incorporated into the wings and horizontal stabilizer to power an electrical engine and charge a 20-kilowatt hour (kWh) lithium-ion battery for energy supply when the sun is out of sight.

Next Generation SolarStratos Plane at a Glance   

  • Length: 8.5 meters – about 30 feet, or the distance from the end zone to the 10-yard line on an American football field  
  • Wingspan: 24.8 meters – about 81 feet, or the length of two standard city buses
  • Weight: 450 kilograms – about as heavy as a grand piano; to make SolarStratos its lightest, the cabin will not be pressurized, requiring pilots to wear astronaut suits that are pressurized by solar energy
  • Engine: 32-kilowatt electrical engine, about one-third the size of what would power an electric vehicle  
  • Energy: 22 square meters of SunPower Maxeon solar cells, each reaching 22 to 24 percent efficiency
  • Batteries: One 20-kilowatt lithium ion battery
  • Autonomy: Self-generates electricity with solar to power the plane for more than 12 hours

"Soaring at such heights requires an unprecedented level of solar performance and durability, making SunPower's unique solar technology a natural choice for SolarStratos," said Tom Werner, SunPower CEO and chairman of the board. "The plane features the same extraordinary cells as those found in our high efficiency solar panels powering homes and businesses here on land – a true testament to our innovation as a solar leader."

In addition to supporting SolarStratos and the solar boat PlanetSolar, SunPower has a pioneering legacy of powering unique solar projects. In 1993, SunPower's high-efficiency solar cells drove a Honda solar car to win the World Solar Challenge from Darwin to Adelaide in Australia a full day ahead of the second-place finisher. The company also worked with NASA to develop the unmanned Helios solar plane that flew to a record altitude of 96,863 feet, also powered by SunPower high-efficiency solar cells. Most recently, SunPower helped Solar Impulse 2 – a single-seater solar plane – complete its groundbreaking flight around the world with zero fuel, the first for an aircraft of its kind.
