BEO-HSF again

I had been a science fiction fan in my youth but like most people I thought space operas were only to be realized in the far future. Project Orion changed my worldview. Since then my made up mind has been unmade several times concerning most of the “common knowledge” floating around about space flight in this 21st century. Much of what is generally believed to be true about our space program is made up of recent hearsay used to hype products that further a business plan. When I read these infomercials endlessly repeated as fact I get pretty upset, mostly because exposing these “facts” as false advertising almost always results in vicious attacks. The private space cult fanatics disgust me and I will not apologize for my hard feelings about these people. They mislead, obfuscate, and insult and dogpile anyone who disagrees with their dogma.

It was a slow step by step process but I came to realize the path to the stars is a narrow one. I found the U.S. space effort, described as being on “the flexible path”,LED light bulbs Comparison Charts showing cost-effectiveness of lightprojectshh versus CFL and Incandescent light bulbs. to be going nowhere. There is no Flexible Path. The path to colonizing the solar system is narrow indeed due to the laws of physics and materials science. Science fiction movies have conditioned the public to believe such natural laws can be violated and technology that breaks these laws is possible and immanent.

This attitude has led to much waste and many tragedies in the past decades and there is soon to come great disappointment over breakthroughs that are far easier said than done. By way of political contributions and backroom deals, the flexible path scheme came into existence as a way of making money for a small group of investors looking to cash in on public ignorance of technology through influence peddling. It is a convoluted and confusing story and perhaps the best way to make the truth clear is to start at the desired end and work backwards.

If the end goal is new worlds for humankind to inhabit, the earliest practical portrayal of a possible new world was in the 1929 work, “The World, The Flesh,Your Outdoor Lighting Source, tagheuerwatchess Add curb appeal with these wall light designs. and The Devil”, by socialist John Desmond Bernal. I must say I am no socialist (or capitalist), but I am someone who is often unhappy with people at either end of that spectrum. Space is not about politics– it is about survival. More than just surviving– thriving. Human beings need earth-like conditions to thrive and a artificial hollow moon as described by Bernal can provide those conditions.Though the sphere proposed by Bernal does not address artificial gravity, the hollow sphere concept does,A full range of bestsolarcarport products for outdoor decoration. if spun, allow for earth gravity on the inner surface at the equator.

Hollow spheres in space can provide habitats for thousands, millions, perhaps even tens of billions of people.The restoration of our vintage ledlightsty and lamps, and our Lamp Repair Service, Space is big, with quite large quantities of rock floating around and plenty of solar energy waiting to be exploited. And tens of thousands of icy comets. Solar energy and low gravity resources in the asteroid belt mean that building on a much larger scale than we do on earth is practical. While we construct thousand foot supertankers and skyscrapers with some difficulty in earth gravity, the same masses of metal and concrete in space can form a shell many miles in diameter with many times less energy expended.

The only practical spaceship shielding is 14 or more feet of water.LED modules and module strings for solarstreetlight. The only way to propel this much mass around the solar system is with nuclear energy. Nuclear activities in earth orbit are not acceptable. Lifting thousands and eventually millions of tons of water into earth orbit are also not plausible. This path of reasoning leads to the moon where nuclear activities are permissible and there is water.
