Does anyone produce a linear alternator of around 1 to 1.5 kW commercially?

QDrive is the only company I know which manufactures commercial linear alternators. Visit www.qdrive.com for details. They manufacture linear alternators upto 10 kW. But I guess they are very heavy!

The Umbra Group (www.umbragroup.it) also manufactures linear alternators from 700 Watts to +50 kW. These linear alternators take advantage of the back-drivable nature of ball-screws to amplify the linear input velocity into higher rotary output velocity which is harnessed for electrical power production. Consequently, these units are much smaller and lighter than competing designs.
