Dear Economist.com reader,
Economist.com invites you to attend an editorial event on
Tuesday, June 27th at 9 a.m. PST/12:00 p.m. EST, featuring Economist Technology Quarterly Editor, Tom Standage, as he discusses critical developments in the field of automobile hybridisation.
By attending this webcast, you can learn how hybrid “hackers†are accessing the control software of hybrid petrol-electric cars such as the Toyota Prius, effectively converting these hybrid cars to plug-in cars capable of traveling longer distances in all-electric mode post-conversion, improving the car’s fuel economy, and reducing greenhouse gas production in the process.
