Pictured is the Greased Lightening drone being controlled with a remote control device The device is small enough to fit in the back of a pickup truck and can be put together and launched in less than 30 minutes.'We take off with a catapult, and land with a parachute, so anywhere you can get a pickup truck, you can utilise our system,' said Silent Falcon's CEO and founder John Brown.
So if the C13 to C12 ratio is falling (as more C12 rich carbon is put into the air by burning fossil fuels) then we can’t know if it’s due to man-made CO2 or natural CO2 from plants.It is a commercial variant of a design that was also being developed by NASA.Although it probably won't be in production for a few years it has benefited from the development of powerful electric motors.'You have conventional airplane UAS that are launched from catapults and have large recovery equipment like nets or skyhooks or things like that', founder and CEO Bill Fredericks told Defense One.C12 makes up 99% of carbon in the atmosphere (nearly all atmospheric carbon is in the form of CO2). Plants don’t like the rarer C13 type as much; photosynthesis works best on the C12 -type -of-CO2 and not the C13-type when absorbing CO2 from the air.Prof Salby points out that while fossil fuels are richer in C12 than the atmosphere, so too is plant life on Earth, and there isn’t a lot of difference (just 2.6%) in the ratios of C13 to C12 in plants versus fossil fuels.The higher levels of CO2 in recent decades appear to be mostly due to natural sources.
He presented this research at the IUGG conference in Melbourne recently, causing great discussion and shocking a few people.
Many companies are chasing a new commercial market and pushing this technology forward which means in the next few years they could become widely available.
A company called Advanced Aircraft Company has created a drone called Greased Lightening which combines the best bits of drone and aeroplane design.
The Greased Lightening drone is a commercial variant of a design that was also being developed by NASA.
Although it probably won't be in production for a few years it has benefited from the development of powerful electric motors'And basically those aircraft, the advantage is like a normal airplane, it gets a very good lift-to-drag ratio,' he said.'Electric motors are really unique, and good efficiency and good power-to-weight electric motors are a relatively new thing to come to the market', Mr Fredericks said.
Many scientists have assumed that the net flows of carbon to and from natural sinks and sources of CO2 cancel each other out, but there is no real data to confirm this and it’s just a convenient assumption. Smith covered this point well in 2009 “It is often asserted that we can measure the human contribution of CO2 to the air by looking at the ratio of C12 to C13.
