Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.


“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

The first solar-powered flight across the Atlantic

The competition heats up: Solar Impulse 2 has successfully completed the first solar-powered flight across the Atlantic in the 15th leg of its journey around the world.

    Never be commercially viable. Now a lighter-than-air craft, like maybe a Zeppelin, would travel faster AND have a useful payload capacity.

    This may be more of a demonstration of current technology. This solar-powered aircraft stayed aloft over the course of 2-1/2 nights. It took off in the middle of the night, demonstrating that the power storage capacity was large yet lightweight.

    Flying to 28,000 feet suggests that there was some weighty life support hardware on board. The pilot would need oxygen and something for warmth. The power gathering and efficiency of the solar cells demonstrates that a piloted, long-distance, solar powered aircraft is much more feasible than it was not so long ago.

    The article, below, says: “It’s a demonstration that the tech is reliable.” But also listen to what the pilot says, in the 1-1/2-minute embedded video, about why they are doing this:

    The Spirit of St. Louis was a demonstration of what was possible. It was not a plane that could carry passengers, but it demonstrated that reliable long-distance flight had finally become possible with the technology available in 1927. These guys are doing something similar, demonstrating some possibilities of solar power, and possibly inspiring other uses, too.
