Roger Billings' H2 Vehicles

An interesting collection of hydrogen-fueled projects features Roger Billings on pages 12 - 16 of this PDF document.

The report covers Billings' Superbeetle win at the Urban Vehicle Design competition, 21-passenger H2 bus, Cadillac Seville used for President Jimmy Carter’s inaugural parade, and The Hydrogen Homestead.

I also found a book list from Amazon with books by Roger Billings concerning his hydrogen projects.
