area, assuming that can be pushed to 200 tons on the 787-8 with some minor optimizations is not an unreasonable assumption. 2.1.2 Performance Range performance data was gathered on the Boeing 787-8, Figure 2, showing how the maximum range depends on the payload weight. A standard payload weight is roughly 21 tons, giving a range of 13600 km. Figure 2 - Range vs payload weight 2.2 Developments in electric propulsion for airplanes Some research was devoted to finding existing designs for electric passenger jet airplanes. In 2011, EADS presented an all-electric transport concept platform called the Voltair, Figure 3. In this research this was found to be the only fully electric design presented by a large company. The design of the plane has been optimized for electric propulsion, making it more aerodynamic and increasing the propulsive efficiency by placing the electric fan at the tail of the aircraft, Figure 5, using contra- rotating fans, as well as designing the wing to have a high share of laminar flow, (Voltair, 2011). 4

Infinity Supercritical CO2 10 Liter Extractor Design and Worldwide Rights: The Infinity Supercritical 10L CO2 extractor is for botanical oil extraction, which is rich in terpenes and can produce shelf ready full spectrum oil. With over 5 years of development, this industry leader mature extractor machine has been sold since 2015 and is part of many profitable businesses. The process can also be used for electrowinning, e-waste recycling, and lithium battery recycling, gold mining electronic wastes, precious metals. CO2 can also be used in a reverse fuel cell with nafion to make a gas-to-liquids fuel, such as methanol, ethanol and butanol or ethylene. Supercritical CO2 has also been used for treating nafion to make it more effective catalyst. This NFT is for the purchase of worldwide rights which includes the design. More Info
