to people who generate and export electricity from low-carbon sources such as solar panels. , Ecotricity does not offer a Smart Export Guarantee tariff to small low-carbon generators such as domestic solar panel systems. Side projects Greenbird Ecotricity is the sponsor of the Ecotricity Greenbird, a land yacht that set a new world land speed record for wind-powered vehicles on 26 March 2009 on the dry Lake Ivanpah. Nemesis Ecotricity has built an electric sports car called Nemesis that was built as a demonstration of what electric cars are capable of: an endurance trip from Land's End to John o' Groats is planned recharging only from electricity produced by wind power. In September 2012 the car broke the UK electric land speed record reaching an average speed of . Vehicle recharging In July 2011 Ecotricity launched a free vehicle charging network sited around the country at 14 of the Welcome Break Motorway service areas, linking London in the south with Exeter in the west and Edinburgh in the north. The charging points were initially equipped with both a UK standard 13amp domestic socket and a high power IEC 62196 32amp 3-phase socket. It is to build wind turbines and vehicle charging points at RoadChef sites across the UK to allow vehicles to recharge directly from the wind. In October 2012 the company started to add 50 kW CHAdeMO fast charging to its charging stations allowing compatible cars to recharge within 30 minutes. In April 2014 it was announced that it would be adding support for Combined Charging System connectors from May and the September had over 120 chargers. In May 2014 it brought an interim high-court injunction against electric car manufacturer Tesla over its vehicle charging network; this was resolved in an out of court settlement. In 2014 the Ecotricity vehicle charging network had sporadic software problems to do with the addition of a new connector which left some chargers not working or not connecting to specific cars. As of December 2014 it covered 90% of the motorway service stations including Land's End and John o' Groats. By December 2015 it had 6,500 members using it once a week or more, and the network, which had hitherto been free of charge, would henceforth require payment. In an interview in March 2016 Vince announced that payment would start in a couple of months and the money from it would be used
