Comment Re:"Small" amount of data (Score 2) 147

Actually, the queries in NoSQL document databases are frequently more useful. For example, the atomic FindOneAndModify() search, which can query any set of data--including array values. You can have data that has { PhoneNumber: [5559992332, 5551112234, 5552201212] } and FindOneAndModify({PhoneNumber: 5551112234}, { $pull {PhoneNumber: 5551112234}} ) and delete that specific element from the array.

Yes of course. We should all read a book that was banned on the important platform of NIGGERS NIGGERS NIGGERS NIGGERS NIGGERS

It's important to ingest material that's considered unwholesome specifically because it contains one word. A lot. The actual content isn't important, and shouldn't factor into your decision on which banned books you should prioritize for ingestion.

Loan rates are somewhat tied to borrowing rates--the bank borrows and re-lends money. Further, depending on loan structure, more or less of your loan could be interest: the payment difference for a small loan can be rather small, $50 or $100, for the same percentage point difference as for a 30-year mortgage.

Comment Re:Plain solar panels cost less (Score 1) 268

It means solar requires massive, heavy equipment to produce the same amount of energy; but the small unit of equipment uses little heavy metal. If you need 1 50 pound unit including 1mg of mercury to produce 1 kW of energy, or 1 50 pound unit including 2mg of mercury to produce 50kW of energy, then you would use 2,500 pounds of stuff including 50mg of mercury to produce the same 50kW as an apparatus using 2mg mercury.

It's a ridiculous statement that comes about by peoples's fascination with the per-unit cost of anything. If you need to buy one of X every week or one of Y every month, but X costs half as much as Y, people will "save money" by buying X for half as much... four times, while claiming it's cheaper.

Actually, this new fangled system produces more heat than electricity, even with the solar panels cooling it--12kW of heat is routed to electrical potential instead. If you had just a flat black collector, you'd get 32kW of heat instead of 20kW.

A solar hot water system large enough to heat your house, with all the rigging and controls involved, would cost about $3000. In the winter, that would save me $1000-$1500; and the heat can run an absorption chiller or desalinating boiler, which would stop my bathroom from coating itself in thick yellow grime thanks to the terrible water I have here. The heat could also run a sterling engine.

A parabolic collector in this fashion, with appropriate materials, could get higher temperatures to run the sterling engine hotter and generate electricity, or drive the adsorption chiller faster.
