In a documentary on BBC One, there was a report about a cleantech company called Synjelion who have developed technology that sucks
water and CO₂ out of the air and uses energy sourced from solar panels to
power a process that produces jet fuel. It's basically a synthetic
version of photosynthesis, except plants make sugar, starch and
cellulose, using water, carbon dioxide and sunlight. All the wood that
makes up a tree comes from carbon taken out of the atmosphere. Meanwhile
we breathe out all the carbon in our food in the form of carbon
dioxide.
