Women in Space ~ Astronautical Advantages...

Nadia Drake in NatGeo writes Here’s why women may be the best suited for spaceflight...

"Physically and mentally, women have the right stuff for lengthy missions in space. So why send men when you can send just their contributions to the next generation, collected and cryopreserved in tiny vials? Sending an all-female crew and a sperm bank lets a space program economize while also increasing the genetic diversity of the parental pool."

PV Potential ~ Mapping Sunpower Worldwide...

The Sun is a giant thermonuclear reactor in the sky powerbeaming 24x7. A tiny sliver hits the daily rotating Earth and then you have to discount for angles and overcasts. When all's accounted for, here's the resulting worldmap of terrestrial potential for PV or photovoltaic sunpower... Curiously enough, most maps like this only show land incidence. But surely we could float massive solar panels out on swathes of ocean? In fact, perhaps we should hoover up the massive ocean gyres of waste plastic and convert these into floatation for PV paneling.
