Scott Posted November 14, 2022 Share Posted November 14, 2022 Australian regional airline Northern Territory Air Service (NTAS) has ordered 20 electric planes from manufacturer Eviation, and they are far from the only customer. Looking back only five years ago, the thought of electric commercial planes was laughable. Commercial jets use enormous amounts of energy just to keep them at cruising altitude, and they are often the choice of travel for trips spanning hundreds or thousands of miles. https://www.teslarati.com/electric-plane-manufacturer-takes-off-worldwide-orders/ 1 Link to comment Share on other sites More sharing options...

That figure is the comparison number between the figure for renewable energy supplies and the existing fossil fuel energy supplies. 260 Gw is certainly an impressive figure but compared to what?

placeholder Posted November 14, 2022 Share Posted November 14, 2022 A recent development that could allow for far greater range is the development of a new kind of flow battery. It's capable of holding a far greater charge than other batteries. The developers claim it could be treated like any other liquid fuel. So you just pump the charged liquid into a tank, the same way that fuel is pumped into a fuselage. Unlike fossil fuel though, the liquid doesn't burn up. When its charge is mostly spent, it's drained and recharged, while fully charged fuel is pumped back into the aircraft. https://newatlas.com/energy/influit-flow-battery-density/ 2 Link to comment Share on other sites More sharing options...

Popular Post billd766 Posted November 14, 2022 Popular Post Share Posted November 14, 2022 Looking at the Eviation website, it lists some impressive specifications for the Alise. The plane has a max payload of 2,500 pounds/nine passengers and their luggage, can travel 250 nautical miles (287 miles), and can achieve a max speed of 260 knots (300mph). And while these specs are far from impressive compared to the ocean-crossing jets we have become familiar with at our local airports, the Eviation Alise could be just as capable as other small jets on shorter journeys. It looks like a nice puddle jumper but with only room for 9 pax, a fixed undercarriage (lots of drag) and a relatively short range, there is certainly room to do better. What wasn't mentioned was how long it will take to recharge and the cost of that. Neither was the life of the batteries nor their cost. AFAIR as a comparison a new set of batteries for an electric car are around halt the price of the car. If some one has a better figure I am always happy to learn more. Has there been any way to recycle these batteries yet? 4 Link to comment Share on other sites More sharing options...
