Comment Re:Watt vs KW/hr (Score 1) 395

That's my point of production cost vs. price. The article stated that currently it costs about $8000 to manufacture about 10kW worth of panels. The new process cuts it down to $4000. However, the current price is about $25000. If all the saving is passed on to the consumer, that would only cut it down to $21000. But you have to factor in capital investments, etc. so most likely you'd save maybe $2000 out of the $20000-$30000 for an installation. That's still 10%, but much less impressive than the 50% that the article seems to imply.

The price ($0.40/W) is the production cost for the PV panel. So, if you want to install, say, a 10kW panel on your roof, the solar panel itself would cost about $4000 to manufacture (as opposed to $8000 by other processes). How much it will cost you, however, still depends on market price, installation and infrastructure cost (batteries, inverters, switches, etc.)

Now, a quick search shows that current panels sell for $250 for a 100W (or $25K for 10kW). And a whole system (< 10kW) is somewhere in the $20-$30K range. What that shows is most of the manufacturing cost of the panels is only a part (30%) of the whole. If all of the saving get forwarded to the consumer, you would see that the the cost might drop about $4K. So basically it'll take 16+ years instead of 20+ years to pay for itself.

After 25 years, you replace the panels and repeat the process, maybe at half the price :)

Comment Anonymity vs. Accountability (Score 5, Insightful) 218

It is pretty obvious that electronic voting requires both anonymity (to remove fear of retributions) and accountability (to remove fraud).

About the only way to do that is to issue each person to have a pass-phrase coupled pair of electronic "vote cards" that is non-identifying. It would require the present of both cards and the pass-phrase to vote. If you lost one card, you can use the other (plus the pass phrase) to invalidate the lost card (and any recently casted votes.) If you lost both cards, you are SOL. No vote for you.

So, you just can't have a reliable electronic voting system.

With Windows XP going away, in a few years you might be looking for an old box to run your favorite program. In another few years you might be completely out of luck. Even further out, what if Microsoft went bankrupt (or bought by Apple, Google, RedHat, whoever) and their OS division is shelved?

Projects like ReactOS, Wine, DOSBox, etc. allow you to have another possible path in that uncertain future. Your program might not work out-of-the-box, but you have the source to tinker with and try to get it to work.

That is probably the same reason for running Wine on Windows, which is probably better than running an old program within a virtual machine.

Soon enough, you will probably run all of your programs in a browser anyway. But I digress :)

Comment Ergonomics (Score 3, Informative) 402

The biggest issue I have with the mirror less / micro four-third camera families is with ergonomics. These cameras are:

1. Too big to put in your pocket/purse/etc. so you don't carry them around as much as a point-n-shoot or a cell phone.

2. Too small to hold for a good posture to take pictures (one hand under the lens) yet the weight dictates some sort of two-hands operation.

3. Additionally, the "advanced" controls are buried deep under layers of menus, make them less usable than some of the more advanced point-n-shoot (like the Canon S100)

4. Lenses are not interchangeable with SLRs, so there is no upgrade path for those investments.

I would recommend you look at an entry-level DSLR (since the price points are close). Started out with the "green square" (automatic) modes, then learn to shoot in "P" (programmed) mode, adjusting ISO and compensations. Then move on to Av / Tv / M modes.

What you learn using a DLSR will be applicable to all cameras, and your investments in lenses won't be wasted.

Don't get me wrong, I think the mirror-less stuff is great, but the current crop of cameras leave too much out.
