The five finalists in the spotlight
Willem Kesteloo (28, Delft, the Netherlands): PHYSEE
Physee’s windows boast the first fully transparent energy-generating glass. A coating collects light that would normally be reflected, and solar cells in the frame convert it to electricity. In dense cities, commercial buildings can account for most carbon emissions. PowerWindows can supply half the energy for a renovated commercial building and up to 100% for a new building. Optional tinted panes for hot climates produce more electricity while cutting cooling costs.
Tonnis Hooghoudt (55, Eindhoven, the Netherlands): Ioniqa Technologies
Ioniqa’s developed a method that enables upcycling of mixed PET waste – any colour, and from drink bottles to carpets – into competitively priced virgin material, closing the PET loop for the first time. The world produces tens of millions of tonnes of this ubiquitous plastic each year, and 90% is later burned or dumped. Reducing incineration and new production would have a serious impact on CO2 emissions.
Hilla Benzaken (28, Beit Yanai, Israel): HomeBiogas
This backyard unit uses bacteria to turn kitchen waste and animal manure into clean cooking gas and natural fertiliser for household use. Biogas can be used for cooking, lighting, and heating water. Using it as a substitute for firewood, coal or charcoal eliminates harmful indoor smoke. Rotting waste generates CO2 and methane; the company estimates that capturing and burning them can reduce a home’s net GHG output by the equivalent of 6 carbon tonnes.
Denes Honus (29, Dresden, Germany): Green City Solutions
The moss cultures in each 4 x 3 metre CityTree installation “eat” as much fine-dust air pollution as 275 trees. Each unit takes 1% of the space and 1% of the costs of a real tree. Smart sensors facilitate monitoring and control, and solar panels and rainwater retention minimise maintenance. The “tree” could help cities meet pollution-reduction targets where other technologies have failed, and even reduce temperatures.
Harrison Leaf (29, Manchester, United Kingdom): Steama.co
More than a billion people live off-grid, and they need renewable replacements for kerosene and diesel. But scarcity of capital can present an obstacle for would-be providers. Steama.co’s smart-metering software lets sustainable microgrid owners sell pay-as-you-go utility services to help finance their assets and enables reliable remote management of systems using a robust GSM network. This makes it financially attractive to set up and operate sustainable microgrids. The product is on the market and has been deployed on 38 microgrids in Kenya and Tanzania.
Winner to be announced during the final on 14 September
The five finalists will attend the final in Amsterdam on 14 September. Here they will pitch their business plans to an international jury, the press and the public. Her Majesty Queen Máxima of the Netherlands will be present at the final. The winner will receive €500,000 to further develop and market his or her product or service. The runner-up will receive €200,000.
