Well, normally it's snake oil time when anyone talks about using electric charges/magnets etc to improve fuel efficiency, but when it comes to viscosity reduction, a US Department of Energy Test seems to show a significant temporary reduction in crude oil viscosity using the STWA device
As I...
I just had this one floated by me.
We need to put an analyser in a bypass but we have a maximum pressure limit on the sensor below the maximum pipeline pressure when the high pressure pump is running.
I'm thinking that a downstream pressure reducing regulator would drop the pressure to the...
Has anyone here used the Excel Solver for linear programming?
If so how easy did they find it and does it then easily translate to a web program?
Any pitfalls?
There seems quite a lot on the web and one source seems a good starting point.
Any recommended aids?

This interesting article caught my eye.
I've no doubt many would like to believe it is true but is it too simplistic?
Does it ignore political factors?
Is the fear of the poor justified?
Despite the number of millionaires and billionaires in China today and the vast "middle class" the majority...
The balance between more complexity and increased efficiency - will it pay off?

From MIT comes news of a new paper claiming that nanocopper catalysts can help convert CO2 to CH4......
This seems a bit like perpetual motion to me. You burn fuel (including CH4) and get CO2 and H2O etc. and then convert the CO2 back into fuel?
But the claim is that it will reduce greenhouse...

This is a problem I came up with when reviewing bunkering. I've posted in Linkedin but I know I'll get the usual people chiming in about how wonderful coriolis meters are and touting fuel additives etc. so better here....

I've been taking a personal interest in moulded components (an area of my mind largely composed of ignorance) and rummaging in my library overflow (boxed in the garage) I came across this book:
"Liquid Moulding Technologies"
Woodhead Publishing Limited
1997 edition.
A hand written sticker says...
Oxtane!
Might this one actually work?
I've seen a couple of snake oil posters over at linkedin bt this has a better line of jargon than most.......but its those electrons again.... and why don't I just add one of those no moving parts clamp on the outside of the pipe "Energiser" thingies?

At the risk of being shot down for not googling properly, I have a query way outside my field.
I am trying to discover the penalties of poor product design.
I have a fairly simple component that is to be moulded and the final component should meet very precise dimensional properties and should...
Well, not a hoax as the original thread was initially careful to consider, and as anticipated there, a new tranche of emails has now been released.
Yes folks, its Climategate 2.0 and better late than never(I was anticipating a second release much earlier as revealed in the original threads)...
I was just validating some links in my bookmarks (nothing worse than dead links) and I thought this link to the Fisher ISA specification sheet program might be of use:
The blurb says:
You can download the program from here.
I hope it of use to someone.

Thought this might be the best cross forum location to post this link to a web site which seems to link to a huge range of online calculators.
It includes Elizabethan costumes (whatever that calculator is) and a wide variety of engineering calculations.

On the whole, the more I use Excel the more impressed with it I am as a powerful and flexible tool.
But, and there is always a "but", there are some irritations.
I am using Excel 2003.
When you enter data in a cell and click enter, the cursor then moves to the next cell below it.
OK, but I...

I have a problem (Excel 2002) which [i]isn't[/1] solved by setting calculation to automatic.
I already have calculation set to automatic.

I thought I'd got this spreadsheet (Excel 2002) done and then I get a change request.
I make a correction and get a circular reference.
I'm tracking it down and think I've fixed it when I find something totally screwy in a couple of cells.

AM15 = 11.6834, the result of a...
It really is time I was better educated and that I learned how to do things the right and economical way; to become more proficient in Visual basic (there is a limit to what can be done with If statements).
Can anyone recommend any good guides for "Teach yourself VBA"?
Idiot's guides, please...
In Excel 2002, how do I get a formula to put its result into another cell?
A1 sheet 1 is unprotected and contains no formula and the user may write to it.
This value may be used in a calculation.
But if he chooses an alternative calculation I want the calculation result written here.
Hence...
