I spoke to a chap the other day who instructs on a Velis (?) the electric cousin of the Virus SW. They even let students solo on the electric thingy. Range is limited to around 200 kilometers with careful treatment but only half of it is used. Good for pattern work and a 50 NM XC will work too. But you need to have industrial grade power connectors to charge it via some clumsy box. Not bad but not there yet.
