again as i have before, The OEM's are no ware on this technology, If they believe that a sustainable product is an electric truck that uses fossil fuel to produce the electric there will be in trouble.

In Colerado USA NASA have a fridge.In that fridge there are Ice Core Samples from around the World with a 1 million year history of Atmospheric Conditions on this planet.It shows a definite pattern to the run in to an ICE Age
Firstly you get high CO2 concentrations ie over 500ppm we are at 450 now in 2018-09-30 This causes the onset of Global Warming
Once the Temperature Rise exceeds 2 Deg C Methane Gas enters the Atmosphere from Ice and under the Sea This causes Thermal Runaway because Methane is 25times worse as an Insulator compared with CO2 Over a period of 20 to 40 Years the average temperature rises to 40 DegC Such high temperatures cause the Earth to become surrounded by cloud and sunlight is excluded
The temperature flips to minus 40DegC for up to 10000 years and resets when methane has decomposed and CO2 levels fallen to 200ppm
