Про цей епізод

<p>Chemist Andrea Sella explores the current race to do photosynthesis better than nature ever achieved. </p><p>In just a few hundred years mankind has burnt fossil fuels that had taken natural photosynthesis billions of years to create.</p><p>Now, around the world hundreds of millions of pounds are being spent on the race to develop a robust, cheap and efficient way to turn the light from the sun into fuels we can use. </p><p>At a time when politicians everywhere debate the economic and climatic burdens of our future energy needs, such a "solar fuel" would be a genuinely novel alternative energy.</p><p>(Image: Some beech leaves.
