Here is a prospective LSR machine that was intended for GP racing.............but alas it did not happen

Notice the departure from common thinking at about 5 minutes in.

History / Fresnel lenses and Lighthouses

This section has been quiet for a long time. Here is my effort to give it a small boost. History is fun.......sometimes.

Michio Kaku can be entertaining, in part because he's willing to pontificate on topics well beyond his area of expertise. He's not above spreading baseless speculation. I tend to take most things he says with a side of sodium chloride.
Yeah, it's fun to speculate on the nature of the unknown.

My personal take is that the great filter takes care of life before it spreads too far. Also, I suspect the filtration mechanism may be a multi-part affair. Species around volatile stars may not survive their outbursty nature long enough to leave their planet. Species that arise towards the end of their star's life may not survive that. Species around the most stable of red dwarfs may not survive themselves - or some other, more natural Great Extinction, quietly going the way of the dinosaurs. Some might even reach space and be able to sort-of navigate it, but not be able to breed or mature outside suitable planetary conditions. I think it would take a set of rare circumstances indeed for a species to even approach interplanetary - not to mention galactic or intergalactic. The universe - it is a hostile place of mostly-nothing-sprinkled-with-fire.

The Asmo does evil to the sound of O Fortuna :smilenod:

Michio Kaku suggests that one day huge worm holes could open up to allow us to escape the death of our universe.
I guess that some intelligence might already be able to do this to explore the galaxy.
Brian Cox argued that as we have never detected their probes then intelligent alien life does not exist in our region of the galaxy.
Martin Rees does not rule out we might one day detect their AI.
Then Avi Loeb identifies the fast moving Oumuamua with an alien probe.
He went on to say it wouldn't look like a probe to us.
Like a cave man would just identify a mobile phone as a rock.

One thing I'm sure about is if it looks like our technology, then it is our technology.
There are no alien Greys or Nordics because they look too much like us.

Rather a mixed bag.  :-\

The violence done not only to self but on the lives of others, mostly family.  :sadnod:

But grandsprogs bring some light. Usually.  :)
