Extra electric aircraft 330LE
boats it ’ s not a big issue because air can be a good insulator , but at altitude the air is much thinner and that effect is less powerful . We need to establish the right levels of insulation on the wiring and the separations between cables and structure to control this difficult phenomenon .”
Efficiency “ Today , high-powered electric motors are around 96 % efficient , which means the other 4 % is coming out as heat . We need to get those losses down to less than 1 % in the motor and transmission systems . All of these elements need to be addressed or the hybrid system will be less attractive compared to a traditional gas turbine because you can ’ t waste the energy you store and transmit .”
Tesla CEO Elon Musk states that once batteries are capable of producing 400 Watt-hours per kilogram , the potential for energy density to beat the weight problem and deliver pure electric transcontinental flight becomes ‘ compelling ’. Currently , it would be impossible to fly from London to Singapore with pure electric power because an aircraft would have to
