Israel’s Anai Green Wins 2020 Women4Climate Tech Challenge For Lumiweave Solar Fabric


“This will provide Lumiweave with a platform for promoting innovative design solutions for tempering the urban environment.”

Anai Green’s Invention From The Inventor

Anai Green, an Israeli inventor, has been named one of the winners of this year’s Women4Climate Tech Challenge for her new green tech called Lumiweave. She will split a $50,000 prize with three other finalists. Lumiweave creates solar powered fabric.

Being in the Middle East and going through increasingly hotter summers in recent years, it makes sense that Startup Nation would be looking for ways to not only provide people shade and protection from the heat, but to also use the energy from the sun for electricity. Anai Green is a pioneer in this field.

Lumiweave not only provides shade during the day, but uses the solar energy collected to provide light at night. This will help with the effects of climate change by both cutting down on the need for more energy for air conditioning but also using the Sun for light at night.

Lumiweave is a new outdoor fabric combining embedded solar organic PV cells for off the grid soft linear light and shade in one street fabric. PV is a photovoltaic cell, an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. This makes it possible to create a range of applications from standalone localized shade umbrellas, to hung canopies, and linear fabric shading enclosures. Lumiweave works at melding both lighting and shading and environmental performance in a new soft material that can be used in a myriad of urban situations.

Anai Green said, “Coming together with the Women4Climate Tech Challenge and a wider audience focused on today’s climate challenges is a unique opportunity to bring technology, design and urban stakeholders together. This will provide Lumiweave with a platform for promoting innovative design solutions for tempering the urban environment.”

Tel Aviv-Jaffa Mayor Ron Huldai said, “One of the most pressing issues of concern regarding climate change in Tel Aviv-Yafo is the rising temperature, a great challenge that we will be contending with in the coming years. Lumiweave’s solar shading structures can bring a unique solution to this problem. We are excited to work with Anai Green to test the solution where it is most needed.”

The Women4Climate Tech Challenge is an international contest open to women carrying out an innovative tech solution for climate action in cities. Complementary to the Women4Climate Mentorship Program, the Tech Challenge is open to all C40 Cities and promotes concrete solutions with a measurable impact. The key goal of the Tech Challenge is to promote, experiment, and implement women-led climate innovation in C40 cities. It provides the winners with support and acceleration from C40 & partners; and the opportunity to pilot solutions in C40 cities.

“When women have the chance to innovate, invent, and lead, our economies, our families, and our environment are better off,” said C40 Chair and Los Angeles Mayor Eric Garcetti. “The Women4Climate Tech Challenge puts the power of saving our planet in the hands of women — bringing bold solutions to our cities and placing them at the forefront of our global effort to combat the climate crisis.”
About Anai Green

Anai is an industrial and product designer who grew up in Israel and attended the Bezalel Academy of Art. Over the past decade, Anai’s interests have extended her work on lighting and furniture to the design of spatial objects and the relationship between materials, form and technologies and bring her designs to impact everyday life in urban settings. In 2010 she participated as a collaborator in Megama – a strategic design office – on an entry for the Landscape Urbanism Biennale called “32N Urban Shade” that focused on the significance of natural and built shade in the city of Bat Yam, Israel.

Lumiweave combines Anai’s interests in emerging LED lighting technologies, flexible PV cells, with the potential of textiles in outdoor uses to address the problem of rising temperatures in urban environments.
