Stony Brook University did a long-term study of the use of concrete, a catalyst and coal ash which did not affect the soil it was in. Proposed was sea walls and other mediating structures. I read a woman in a private company had invented a mixing machine that incorporated small pieces of metal, based on stress and need, in the concrete as it was transported to the forms. The shapes were researched and appeared shaped like carabiners, different size and diameters, allowed concrete in new forms, now stronger than with rebar. Perhaps a stronger “slurry wall” would also be built, and the interface at bedrock, more secure than the flat-ends of a rebar cage. Law requires rebar to be cleaned, labor intensive, when reused for example in a bridge. There was a multiple machine that uses high pressure water to break, remove old concrete and clean the rebar using water pressure. Faster than by hand, the concrete is poured as part of this “train”, which however is very loud.
I was pleased to hear the Tesla workshop at Wardenclyffe, near the shut Shoreham, NY nuclear plant and Brookhaven National Laboratory has been saved for a science museum. Designed by his friend the famous architect Stanford White, perhaps its might be listed in a national register of historic places too, as many of Stanford White’s are. Years ago, the Suffolk County Archaeology Association considered it as a problem while I was there in grad school. An engineering student showed me the remains of Stanford White’s windmill, (125′ tall?) diagrammed in Scientific American as I recall, on his north shore estate near Stony Brook, NY where he also designed a small church in the “shingle style”. The windmill tower burned in the early 1960s a landmark for those on the waters of the Long Island Sound for many years. Maybe he helped therefore to design Tesla’s Tower. All that remains of the windmill are the cast in Baltimore iron stanchions once anchoring it to the ground, bulldozed over the “cliff”.

The museum would be in the former Peerless Photo, Inc. site which was contaminated and mitigated of photo-chemicals. I’m not sure the tower site was kept, the base was shown in the press to be bulldozed when so cleaned or was in the past. The building was designed by the famous architect, Stanford White, who lived not very far away, nearby Stony Brook having built there a “world’s tallest”(?) windmill. He was a victim of gun violence and a moment of insanity. You might think given the breadth of White’s influence, White House, Washington Square Arch, Municipal building, to name a few, that the Tesla lab would be preserved for that additional historical significance. And it’s nearby the Brookhaven National Laboratory!
The other phenomena are seen after wind storms I think. It was reported by a French observer nearby the British Army’s “Fort Golgotha” in Huntington, NY on Long Island during the American Revolution, that the wind and cold had formed “snowrolls” that went uphill. Ironically “Queen’s Ranger” Benjamin Thompson, in charge, would later be known as Count Rumford and an expert on early thermal physics, among other European successes. The fort was built in a cemetery on a hill and was reported that some of the troops to have baked bread on some of the gravestones. It was plowed over later, and some small archaeology efforts done there, the official one, I assisted.
I’ve seen the “rolls” on-line in some of the candid pictures of Scotland in the winter, in what appear to be fairly flat fields, as shown in this photo.

Newspeak “Do think…” I thinks it should as a member of the Planetary Society, which consists of many members from many nations on planet Earth. In the spirit of cooperation the US government could continue to fund space exploration that has kept the interests of the many citizens of the planet excited about the Universe around us along with the research of other nations now also in space. I think(s) “Was it Sir Arthur C. Clarke who warned of a new “Tower of Babel” of communications satellites that just reinforce individual (ethnic) cultures and language without international cooperation?” Though the sir is dropped in New Zealand, they launch near space sounding rockets and make available research payloads to any and all. The spirit of internationalism aboard Captain Husband’s ill-fated Columbia space shuttle should not be abandoned or forgotten.
Safe ports…dawn and dusk vision…”gated” lasers just might in development. Dark NEO’s full of minerals (Near Earth Orbit). Moon distance already being measured with them. “Laser propulsion” near the speed of light. We measure it to record properties, build roads, etc., infrared (visible lasers for tunnels) “tacheometers” or “total stations” are now under $4000. Very accurate.
