Umm, well, actually, yes! well that would be a … well a mmm maybe no the answer to your question would be a y,y, y… would it find him? Uh, well. Um. No. I guess not! If the entire faculties of the US destruction machine can’t achieve this aim then it is unlikely that a robot plane will have any more luck. Happy hunting tho. Just remember…You have to eat what you kill. Enjoy.?!

Comment on Nanosolar Powersheets - reliable solar power by Sangman Hahn

I hope what they claim doesn’t hide anything negative.
Now, the challenge is how to store electricity for cloudy and rainy days, and how to smooth out the power grid for flutuations.

Pricing and cost of electricity can be confusing at times because sometimes it is specified as a rate or an actual amount. Electrical rate is measured in watts or kilowatts or megawatts, which is how much is produced per amount of time. The confusion is because one watt is really one joule per second, so watt is a rate, even though the term doesn’t specify time explicitly. So watt or kilowatt or megawatt is a rate of energy production. As an analogy, if you were to build a factory making widgets, you would talk about how much that factory could produce, that is, a rate of production (e.g, 1 million widgets per year). It’s easy to comprehend because you explicitly mention the “per year” part.

As consumers of electricity, we get billed in kilowatt-hours, which is an amount of electricity that was used in a billing period. That’s why the time is in the numerator, so a kilowatt-hour is really a certain number of joules, in this case 3,600,000 Joules.

So when they talk about this technology being cheaper than coal, they are comparing the cost to produce a rate of electricity over the life of the technology. It is based on the cost to build and install the technology and its operating cost over its lifetime. Coal plants have a fixed install cost AND an operating cost the cost of the fuel (coal). But solar technology has little or no operating costs but does have an installed cost - sometimes called “first cost.”

It’s this installed cost that is the tough hurdle for consumers because it involves a capital investment, something consumers don’t find sexy or desirable, but it sure would more than pay for itself at 30cents/watt.

So the calculation above that guesses on installation cost is probably incorrect because the installation cost should already be part of the calculation as it is surely baked into the figure for coal-powered generation. So if a user would require 25kw-hr, you are talking about $7,500 to buy and install these. The downside is solar is never 100% - you have perhaps 5 hours a day on average where it is producing. This is a big step for solar for sure, but not a panacea until we find a way to store generated power.
