California has so much solar power it has to pay Arizona to use its energy

...But California keeps green-lighting more natural gas plants, thanks to hydrocarbon industry pressure on state regulators, who operate at cross-purposes to the legislature and its targets for renewables. Read the rest

Fill Your Boots: my column on how technology could let us work like artisans and live like kings

My latest Locus column is "Fill Your Boots," in which I talk about how scientists, sf writers, economists and environmental activists have wrestled with the question of abundance -- how the "green left" transformed left wing politics from the promise of every peasant living like a lord to the promise of every lord living like a peasant.

Has anyone tried the ALLPOWERS 80W foldable solar panel?

I'm looking for feedback on this solar panel. I am looking to charge a 37 qt ARB portable fridge while rolling about Baja in my Vanagon. I believe this panel, with good sun, should out put more than enough power to run the fridge.

The Dometic fridge that has been in my VW for 29 years has sucked for 29 years. It barely gets cold enough for cans of soda.

Forums on line claim the fridge peaks around 1.5Ah use on hot days, and this panel should deliver (80w/18v) 4.4Amps. My smallish deep cycle battery is a 44Ah unit. I'm hoping that 6hrs of strong sun a day will get me to just around 24hrs of power.

Unless I get flagged off in the comments, I'm going to order one tomorrow or the next day, and run a test load on the system at my house this weekend. I can't be sure to have strong sun in the SF Bay Area, however.

$20 Water resistant, solar charging, 10000mAh power bank

For $20 I really like this new Matone dual USB battery pack! I haven't found anything better at this price.

The Matone battery is a great combo. I've tried water and damage resistant batteries, and solar charging units -- but this is the Bartles and James of outdoor USB power banks.

At 10000 mAh advertised, I can get around 1 3/4ths full charges on my iPhone 6 with this battery. It seems a bit low, but is certainly enough juice for my needs. Keeping a cellphone running Waze going on an all day motorcycle trip. Charging with the solar panel is slow as there isn't a lot of surface area. I'd consider solar to be an emergency only kinda thing, and not to rely on it for regular charging.

This'll certainly be the battery I use for this Spring's road trips.

USA uses TPP-like trade-court to kill massive Indian solar project

The Jawaharlal Nehru National Solar Mission was on track to deliver deploy 20,000 MW of grid connected solar power by 2022 ("more than the current solar capacity of the world’s top five solar-producing countries combined") but because India specified that the solar panels for it were to be domestically sourced, the USA sued it in WTO trade court and killed it.

NASA looks directly at the sun so you don't have to, and it's gorgeous

NASA's Solar Dynamics Observatory (SDO) in orbit keeps a constant vigil on the Sun to help us understand how solar variations impact life on Earth. Launched in 2010, the SDO is part of NASA's Living With a Star (LWS) Program. NASA just released this magnificent 4K video shot by the SDO of our star's nuclear fire. It's titled "Thermonuclear Art."

IKEA selling solar panels

IKEA has now started selling solar panels in the UK. According the Associated Press, "a standard, all-black 3.36 kilowatt system for a semi-detached home will cost 5,700 British pounds ($9,200) and will include an in-store consultation and design service as well as installation, maintenance and energy monitoring service." Feel free to suggest funny faux-Swedish product names in the comments. Read the rest

Solar pays

Redditor Tufflaw has been running a central air-conditioning system "24/7" during the New York heatwave. But the bills were offset by 26 home solar panels by Sharp that took three days to install and were subject to state and federal tax-credits, and will take 7-8 years to pay for themselves. Here is the most recent bill: $6.05. Tufflaw says that there are sometimes months that go by with no bill at all (and one year generated a $20 rebate from the power company!), and adds, "There's also an intangible benefit, feeling good about using a free renewable source of power."

Been running my central air 24/7 lately, especially with the recent heat wave. This is my most recent electric bill. Damn I love my solar panels. Read the rest

Tool to calculate benefit of rooftop solar in Cambridge, Mass

Gmoke sez, "The city of Cambridge, Mass has teamed up with MIT to produce a Solar Tool that allows people to type an address into a website and get a detailed account of that roof's solar electric potential. This is probably the most detailed service now existing and every building in Cambridge is covered. You can learn how much of your roof sees enough sun for a PV installation, how large that PV installation can be, how much it will cost, how high your Federal and state tax rebate will be, how much electricity it will produce in a year, and how much carbon it will displace."

A Solar Impulse aircraft takes off at Payerne airport May 24, 2012, piloted by André Borschberg. The Solar Impulse HB-SIA prototype aircraft, which has 12,000 solar cells built into its jumbo-jet-sized wings (about 200 feet long), attempted its first intercontinental flight from Switzerland to Morocco with a few days for a technical stop and a change of pilot in Madrid. This flight will act as a final rehearsal for the 2014 round-the-world flight.
