How much solar input would have to be intercepted or re-radiated to compensate for increased greenhouse gases?
For example? what happens if we put some huge reflective panels in L2?

Earth's projected area is about 11.9 million square miles.
What percent...

So, among our various issues in California, we have an aging electric grid.
It may be more an economic /political issue than engineering?

From time to time we see requests for manuals - If you find a good source of manuals, either new or used, please post?
Fanuc used to be decent about having manuals for their controls - don't know how far they go back.
I'm going to call Amada, will post back on what they are willing to offer. I...
Thread starter - I am in the US, and worked for Amada years ago. At that time, we provided application support for customers.
If someone had trouble cutting, or had a new material, we would work with them or run tests in the showroom to figure it out.
AFIK, we even had a software support group...
New to me - obviously heavy on the marketing spin, but still - quite interesting.

On another forum, an interesting photo is posted of a bearing insert.
A modern vehicle with lots of miles, and the insert does not appear to ever have touched the journal.
But, what's interesting is the surface finish of the insert - comments?

Just food for thought -
Has anyone tested or run the numbers to see how far a lens might deflect under high gas pressure?
And, how far would that deflection move the focus point?
I wonder if that would help explain some of the rules of thumb regarding focus height when cutting various...
More tales from my Sister the truck driver.
Not just a driver, she and her hubby are owner-operators. That is, they each have a late model Freightliner and put some serious miles on them.
The unit in question is still under warranty, with only 2-3 hundred thousand miles on it.
It seems that...

Snake oil?
Or some combination of good technology and **?

Anyone have one of the old Prima Optimos, especially one of the (US) Amada systems? (CRG 306, Coherent EFA 51 or Arrow)
This is mostly curiosity - I worked on that project, wondering how many are running nowadays.

Sorry, my Google-fu is filing me today.
I thought there were some ratings for brake pads, in terms of temperature resistance/behavior, effectiveness /grip hot versus cold.
Most of the "info" I can find is subjective and/or inconsistent.
help?

I'd like to find load ratings and specs for various ball joints-
I'm reworking a suspension and would like the spring loading on the lower arm instead of strut/upper arm.
I'm sure the original lower ball joint isn't rated to carry spring forces, so maybe I can find a standard /similar unit...

just for fun-
some time back, I ran a test on a Fanuc 16-based laser system. I created a simple program with x,y coordinates about .002 inch apart. (actually a 2" circle).
I recall it would only go about 5~6 inches/min because the controller wouldn't process the instruction blocks any faster...
