Of course China is the biggest market for electrics, about 30,000 a month in sales and rising. The Chines government wants electrics. The biggest manufacture of EVs world wide is a Chines company called BYD ( Beyond Your Dreams ) in fact you may own one of their, products the battery in your mobile phone. As of today electrics with 250 plus range are available at around £32,000 from several manufactures, the Kia being about the best at this price/range point. In aircraft it is not really viable until a battery of 2.5Kw/hours/Kg is available. So I believe all these electric aircraft so far are, just getting ready for this battery when ? may be another 10 years.
