    Lang's Challenge :: AWE running with little human attention for 700 hours. LC is a target yet to be reached. Send in what you know towards this target: Notes@EnergyKiteSystems.net
     
    The LC might be easier to achieve than one might first think. Consider a Tipping Boom system with short tether in a nearly no-wind site; the wind picks up a bit and the kite drives the generator. Let 700 hours pass and presto, the AWE system could be said to have been running. What say you?

Other types of final discharges are known as heat lightning, summer lightning, sheet lightning, ribbon lightning, silent lightning, ball lightning, bead lightning, elves, jets, and sprites. Well before these discharges are observed, as the atmosphere becomes agitated by wind or thermal activity, static electricity is being generated. "   Source. by   Mark Ellery Ogram

    •  Low & Slow was the first mid- 1900's for-profit magazine to serve that era's hang gliding renaissance. This took over the non-profit Low, Slow & Out of Control by way of contract between Richard Miller and Joe Faust.  Low & Slow became the organ for the international organization Self-Soar Association (S-SA).  At 36 issues, it was replaced with Hang Glder magazine as a weekly: Hang Glider Weekly.  The same publisher formed the first Hang Gldier Manufacturers Association (short lived) and published  a business weekly for such: Hang Glider Business Weekly. All totaled the publisher had 208 editions of hang glider materials. Later the publisher continued publiishing on the Internet. See JoeFaust.org.  
    • Low, Slow & Out of Control  was a non-profit approx. 30-subscribered newsletter by Richard Miller within the fraternity of the Soaring Society of America dedicated to hang gliders and foot-launch sailplanes. Circa 1967
