yes, I was just recalling something that might be more marketing spew than anything else, but there was talk of bigger system that would be appropriate for Mars landing.
A tungsten rod weighing 11 ton has the impact energy of only 9 tons of TNT...in other words, it's better to just use explosives on earth than waste time with any stupid wimpy-energy kinetic impactor from space. and the stuff can't be accurately targeted with its pathetic yield.
Weight from space in quantities humans could mine and refine is NOT like a nuke. Sure, a 1 kilometer wide asteroid is...but we're not talking about that.
fusion reactors for electricity has been right around the corner since the 1970s.
It isn't going to happen in the next 30 years.
we can use the fusion reactor in the sky. we have the means to store solar energy now, so can even use it for base load (contrary to what some dinosaurs living in the past keep parroting here)
hilarious how the populace turns a blind eye to the government that sponsors the most terrorism, the most malware, the most regional destabilizing, the one that gives support to the world's cruelest dictators.....yes, that's the USA.
there is plenty of it, millennia of fuel supply....but....
we don't need it now.
A mere hundred square miles of solar arrays in sunny places would power the USA, and existing tech can store and distribute it (yes, in production 1500 mile UHVDC lines are reality)
It shows the short sighted stupidity of Chicago (and cook county for that matter) not having long term revenue sources.
Chicago already have sold off other assets for short term book balancing that would have provided many times the revenue for OVER A CENTURY. It's disgusting.
The mayor of Chicago is one such idiot, that sawed off incompetent runt Rahm Emanuel.
not stupid at all, the tests don't predict what grades a student will get in college. My ACT scores were near perfect, but my Uni grades weren't outside of my major and minor
you're funny, I live here, have lived here over half a century. take blue and other lines all the time since childhood. would NOT need to widen the portion of blue line that is underground downtown for an express line. that would be above ground and same cost as any other elevated track (and might not even be necessary to build much new track if joined and run around loop with other lines)
there are already multiple existing plans for doing this over the decades by the way. I'm old, I've seen them
we already have that, it's called the Blue Line. heh.
Really just need to make a set of express rails for Blue Line, no need for tunnels and no need for Musk. In some places the 2nd lines would be up in the air over grade track, which of course is how most the CTA train tracks are anyway, it's 125+ year old proven Chicago tech, we're good at it.
The stupidity and waste of this proposed project is unbelievable.
no, world was different place 100 years ago when entire countries had market need. In the here and now, big companies will do it, and little car makers don't stand a chance

haha, cherry picking slow cessna and fast car.
something like a gulfstream goes 600+ MPH.
average auto speed isn't 50MPH.
100 mile trip in plane is much safer than car.
there are wax coated ones that don't do that
yes I was there in 60s and early 70s with the horrible paper straws
no that article makes it 19 times riskier when talking of miles
slicing per hour comes up with one-sixth the accident rate of cars.

nope, read your kinetic energy link

Couldn't they try their hypergol engines for landing?
no you're getting your stats all mixed up. that's per 100,00 hours
flying "general aviation" is MUCH safer than driving somewhere
Yup, automatically throw that patient into palliative care and let them die.

the U.S. doesn't hold health (and climate and carcinogen) data for ransom?
oh?
wrong, we can store solar energy. we can store energy from wind.
so it can be used for base load
psychology has fads and trends, it's a "soft science"...and all of it could be a sham

President Clinton signed the bill which cancelled the project on October 1 1993.
Are you a child? I was part of it, I worked on the SSC at Fermilab.

Solar doesn't get government subsidies? It does.
Wind doesn't? It does.
Hydro doesn't? It does.
Fossil fuel gets the most.
There is no valid point to this article.
The original sentence is quite clear and does not need rewording, you are severely autistic and can't communicate with normal humans.
your beamish words embiggened my soul
you can thank the Democrats for that
I would reject it.

wrong, article is equivalent of saying 50 +/- 50 soldiers are coming. in other words, it is useless bullshit.
credible studies show antarctic ice *growing*, I'll believe NASA over *nature* alarmist hippies any day of the week
