For those of you that may've missed the first half of our Top ten unusual environmental projects blog, here are the five remaining favourite finds from our top ten list of 'green' projects in the works.

Huge thanks to those of you that commented and tweeted us regarding this list - we're still keen to hear more creative concepts that may've been overlooked this time.

    Experts at Plymouth University are working towards sending an autonomous, solar-powered ship across the Atlantic – something that could revolutionise cargo and even passenger shipping. The launch is due in 2020, to coincide with the anniversary of the 'pilgrim fathers' setting off for America on the Mayflower. 


  2. Driverless racing car

    A different sort of driverless vehicle looks set to take to motorsport's tracks soon. Roborace is a new addition to the Formula E electric car racing series – an opportunity to promote autonomous driving and allow technology's best and brightest to hone their work. Lewis Hamilton et al may well be out of work a few years down the line.

  3. Sweet-toothed fuel option

    Scaling up hydrogen production for fuel could be aided by the creation of 'Sweet Hydrogen' from sugar. Current methods of producing hydrogen, from heating fossil fuels and the electrolysis of water, are carbon-intensive and expensive respectively, but it is said that a sugary solution could alleviate both these problems. 

  4. Bacteria does the recycling

    One of plastic pollution's main offenders, polyethylene terephthalate (PET), could be tackled thanks to the discovery of a bacteria that breaks PET down using two enzymes and tendril-like threads. With only about four percent of the huge amount of PET produced each year recycled at present, it could be a discovery in the nick of time. 

  5. Building materials from the air

    As we get better at capturing CO2, something has to be done with it. A pilot plant at the University of Newcastle, Australia, aims to perfect a process that chemically combines it to create a base material for cement, paving stones and more.
