They're talking about purchase and installation:

"Because less modules are needed for the same power output, less land, labor, mounting structures, wiring and support racks are also required, saving an estimate of 10 cents a watt for every point of efficiency gained."

So if you're installing 4000 watts worth of panel, using 23% efficiency panels costs $400 less to purchase and install than 22% efficiency panels.

I was under the impression that Tesla vehicles used banks of off-the-shelf 18650 Li-ion batteries. Panasonic is their current supplier if I recall. Even their proposed battery plant in the southwest is really a place for Panasonic to manufacture batteries for Tesla. Yes, they package them well and I'm sure they have some great controls and associated hardware and software, but is there really something groundbreaking about their batteries specifically? They already make a powertrain for Toyota - a move that hasn't produced a fraction of the buzz and money as their own vehicles. Not sure I understand this suggestion.

For one thing, this isn't USPS. It's UPS. I expect the laws are different for that.

For another, the part apparently wasn't addressed to him. It was misdelivered. If someone else's mail ends up in your mailbox, you don't get to open it and keep whatever's inside. If it's not addressed to you, you're not allowed to open it at all.

It costs a lot more than a new PC to upgrade thousands of PCs. Imaging, deployment, backup/restore processes for the end users is just the beginning. Upgrading dozens, hundreds, or thousands of individual customized applications to be compatible with Windows 7 is an absolute nightmare. I know all about this just from upgrading my relatively small workplace from XP to 7. It was a fight just to get core, mission critical apps to work with IE 9; 10 and 11 are out of the question. Lots of cash to vendors and app support folks, lots of cash to deployment specialists, lots of overtime. Adds up to a LOT of money.

By the way: $9 million over 680,000 PCs is $13 per PC. That's less than we paid per PC to have a contractor come in and physically install new machines at desks, and completely ignores the cost of OS licensing, hardware, support, and the thousands and thousands of man hours the IT department spent with associated tasks.

Nature doesn't "consider" anything. Your argument is basically that nature will adapt around us. Yes, it will..... but it might "adapt" in ways that eliminate important species, destroy biodiversity, and generally ravage the environment around us. Nature may "adapt" in ways that suck total ass for both us and millions of other species.
