Last September Willem Kesteloo won the 10th edition of the Postcode Lottery Green Challenge with his start-up PHYSEE. We were wondering how he and his team are doing now the dust of winning the competition has settled and asked him three questions.



The final of the Postcode Lottery Green Challenge 2016 is a wrap. For the five finalists, an incredible adventure came to an end. Curious what happens yesterday? Please check out this compilation video.


The Dutch green start-up PHYSEE is the winner of the tenth edition of the Postcode Lottery Green Challenge. Co-founder Willem Kesteloo impressed the international jury during the finals in Amsterdam with his PowerWindow. In the presence of Her Majesty Queen Máxima he was handed a cheque for €500,000 to further develop and market his product. The runner-up prize of €200,000 went to green entrepreneur Zhengliang Wu of Green City Solutions from Germany. The other three finalists were given a pleasant surprise as well as they all received €100,000. This is a once-only occasion to celebrate the tenth anniversary of the sustainability competition.




Everyone has heard about the plastic waste ruining our planet by now. But who knows about the 13.1 million tons of textile waste (worth roughly USD 350 billion) the United States alone produce every year? And who knows that 11 million of that textile waste goes almost directly to landfills?  What’s more, it takes about 700 gallons of water (that’s 2650 liters) to make one T-shirt.


Wind turbines are a wonderful invention, producing clean energy from an abundant natural resource: the wind. Since the oil crisis in the 1970s, we’ve continuously developed new and more efficient wind turbines. Key to an efficient wind turbine is a steady flow of… you guessed it, wind. The higher in the sky, the stronger and more constant the wind. This poses a challenge as it requires us to build quite tall wind turbines to reach this “sweet spot”.
