Silicon carbide converter: A consortium of British companies led by Prodrive developed a high-frequency DC-DC converter with a efficiency of 98.7%. The converter, which is currently fitted to a Tata Vista test vehicle, acts like a hub connecting high voltage battery, motor, a super-capacitor bank and 12-volts auxiliary system.

Wearable mobility is what Acton classifies their RocketSkates as. These skates are not propelled by rockets but by small electric hub motors, allowing for a speed of up to 12 mph. Within just 24 hours, their Kickstarter campaign raised more than enough money to fund the project.
