Alaka’I is Hawaiian for “the value of leadership” according to an island management consulting firm.  The word and the company have found a home in Boston, Massachusetts, where they look over the Alaka’i Skai, a hydrogen-powered sky taxi that will offer “point-to-any-point transportation that [is] safe, simple, zero-emissions, affordable and comfortable.” Alala’i, founded by Brian Morrison, adds a hydrogen fuel cell hybrid-electric craft to the eVTOL market with a design by BMW-owned Designworks.    From above, it looks a bit like a water-skipper, probably an apt look considering its fuel.  Alaka’i emphasizes three points in its sales literature: simplicity, safety and the cleanness of its fuel and operation. With several patents supporting the aircraft the machine supports its creators’ backgrounds, including …

Harold Bate and a Little Prehistory This is not a new idea.  Harold Bate, a Devonshire farmer, became a counter-culture hero in the 1970s by powering his Hillman Minx sedan with manure.  Like all visionaries, Harold was a bit ahead of his time, but became well known and envied when the Arab oil embargo of that decade …

This week, an article referenced from Green Car Reports says that EV batteries may already have fallen to $250 per kilowatt hour.  This would be a godsend for sales of battery-powered cars, because sticker prices would drop sharply.   The article quotes Wolfgang Bernhart, a partner at Rolan Berger Strategy Consultants, that battery prices are already much lower than previous predictions would have indicated, possibly as low as $250 per kilowatt hour.  His analysis credited economies of scale for this …
