HO-68 orbits
by ANTHONY JAPHA 08 Apr '10

I've been away from the birds for a while, and when I checked the HO-68 schedule for this week, there appeared to be no times available with East Coast/Europe openings. If that's correct, is that the usual case or a fluke? I'm sure someone has asked the control ops abt. it. Tnx and 73, Tony, N2UN

Lithium-Air Batteries Promising
by Clint Bradford 08 Apr '10

08 Apr '10

Lithium-air battery technology looks to have a big future. With the potential of providing energy densities up to three times that of the conventional lithium-ion batteries found in just about every portable consumer electronics device going around (not to mention the incoming wave of electric vehicles), many companies, including IBM and General Motors are pursuing work on lithium-air batteries. Now researchers at MIT have made a breakthrough that could help make the commercial development of lightweight rechargeable batteries a reality.
