Topic Propel Boats Directly Into The Wind by Kite Systems

Sailing Into Headwinds Using Wind Power
by Harry Valentine, 5/18/2020
From article The physics of sailing: "Sailing directly upwind (exactly anti-parallel to the wind, like the boat at right) is also easy to understand: it's impossible (impossible with sails: a boat with a wind turbine driving a propellor could go directly upwind.)"

Harry,
kPower is focused on CA Polar First Nations Communities as AWE early adopters. We have worked out simple rigging for TRL9 COTS power kites to convert diesel generators into kite hybrids. The dirty secret in AWE is that its hard work (or great fun, if you love kites). The First Nations hate their winter diesel dependence (no solar option), and mastering kites will be a new basis for their cultural viability.

We have active connections to CA First Nations, but Covid has put current on-location R&D on hold. Hoping you can help Canada be where AWE first takes hold to power communities.

We hope you will attend a Seattle conference next year, if we swing it. Hoping DaveC is lurking here. He must know Makani collapsed just as predicted in 2007 (wrong stuff). Hoping some big OLs are around to haul on cableways and demo MW power.

Attached graphics lay out some basics, just a taste of countless kPower experiments and ideas.

Great that Harry is still in! Count on him for the AWECs.
