Assuming my townhouse has a roof that is optimal to get full coverage from an optimally angled 100% efficient photovoltaic cell that is 16 square meters in size, on a clear day my solar array would produce on December 21st a bit over 10.6 kWh on average. So 254.4 kW per day on the worst day of the year.

The Tesla S uses 85 kW/h. I could drive 3 hours a day, assuming no household use and perfect transference/storage.

Or more realistically, 1 hour a day, and that leaves 269.4 kW for household use. Since the average household in the US of 1500 sq.ft. uses 864 kWh per month, I'd have an excess part way through the third day to "sell" to others.

So even at 50% efficiency, I'd have plenty of power, assuming clear skies, and the worst day of the year to gather every day.

Gift Idea: Custom Photomosaics With AndreaMosaic and PhotoGrabber 61

Bennettt Haselton has a gift idea for this year that needn't necessarily cost you any money (if you have a color printer available), though as he points out there are ways to invest in a higher-quality result. The gift? A unique picture created with a few pieces of free software and a bit of your time. Bennett writes: "You can use these little-known free programs to create a photomosaic of a friend's wedding photo or other favorite photograph, for a uniquely personal gift that doesn't cost much but can still delight. Follow these steps to use the programs most effectively and get the best results." Read on for the rest.

Submission + - FCC Chair: it's Ok to Discriminate Traffic 2

sl4shd0rk writes: Remember when the ex-cable lobbyist Tom Wheeler was appointed to the FCC chair back in may of 2013? Turns out he's currently gunning for Internet Service Providers to be able to "favor some traffic over other traffic". A dangerous precedent considering the Open Internet Order in 2010 forbid such action if it fell under unreasonable discrimination. The bendy interpretation of the 2010 order is apparently aimed somewhat at Netflix as Wheeler stated: "Netflix might say, 'I'll pay in order to make sure that my subscriber might receive the best possible transmission of this movie.'"

Submission + - Understanding "energy trilemma" of energy security, sustainability, & equity (thebulletin.org)

Lasrick writes: Adnan Hezri explores the dilemma developing countries face in moving toward a sustainable future, given the difficulty of incorporating climate change into energy policy: 'Over the coming decades, fast-developing nations are likely to account for an ever-increasing share of global carbon emissions—particularly China, India, and Brazil. But in the poorest countries, the biggest challenge continues to be energy access itself. Even the world's biggest carbon emitters haven't yet fully incorporated climate change into their energy policies—so it should come as no surprise that, in the poorest countries, transformation of energy systems is usually not even a fringe consideration.
