Batteries vs. fossil fuels

Another battery entry, Ambri with a liquid metal battery and $50 million startup funding, understands it’s the battery market vs. fossil fuels. And batteries plus sun, wind, and water power will win.

Jeff McMahon, Forbes, 4 June 2015, Want To Build A Better Battery? Don’t Talk To Battery Experts,

Like Tesla’s Powerpack, Ambri’s liquid-metal battery is designed to provide grid-level storage that can supplement intermittent renewables like solar and wind, making a grid that depends on renewables as reliable as one that depends on fossil fuels or nuclear reactors.

Wednesday night, [Ambri founder MIT Professor Donald] Sadoway welcomed Tesla’s entry to the grid-level battery industry. The competition, he said, is not between batteries, but between batteries and fossil fuels.

Tesla announces prices for home battery

Power generation for both traditional electricity uses and transportation is changing.

Michael Liedtke and Jonathan Fahey wrote for AP and Inc. 1 May 2015, Elon Musk Unveils Tesla’s Ambitious New Home Battery System: “Our goal here is to fundamentally change the way the world uses energy,” Musk told reporters gathered in Hawthorne, California.

The batteries are likely to become more useful if, as expected, more utilities and regulators allow Continue reading →

Videos: Peggy Green apologizes to Nydia Tisdale to avoid jail time

Tuesday morning assailant Peggy Green apologized a year after Nydia Tisdale asked. The judge remarked he was happy at the outcome so nobody had to face jail time. So, if you want your meeting to be private, don’t advertise it as “open to the public”. And when someone shows up with a camera, don’t try to throw them out, especially not physically.

From Nydia’s blog post here’s the video: Continue reading →

Nydia Tisdale fights back, requests criminal arrest of assailant this morning in court

This morning at 9:30 AM, a judge will hear Nydia Tisdale’s request for arrest of someone who tried to take her camera and threw her out of a meeting advertised as “open to the public”. Go Nydia!

As usual, she has the whole thing documented: Republican Women of Forsyth County GA kick citizen & camera outta public meeting 04/16/14. As you can see in her blog posts, at least one of the candidates for election at that event apologized for what happened to her. Also later the owner of the restaurant told a police detective that he had not asked her to leave, despite Peggy Green’s statement in the video of the event.

Nydia asked for an apology. She didn’t get one, so this time she filed for an arrest warrant. Continue reading →

Stanford aluminum battery

Another entrant in the battery race to clean energy storage.

Mark Shwartz, Stanford PR, 6 April 2015, Aluminum battery from Stanford offers safe alternative to conventional batteries: The new aluminum-ion battery could replace many of the lithium-ion and alkaline batteries in wide use today.

Stanford University scientists have invented the first high-performance aluminum battery that’s fast-charging, long-lasting and inexpensive. Researchers say the new technology offers a safe alternative to many commercial batteries in wide use today.

“We have developed a rechargeable aluminum battery that may replace existing storage devices, such as alkaline batteries, which are bad for the environment, and lithium-ion batteries, which occasionally burst into flames,” said Hongjie Dai, a professor of chemistry at Stanford. “Our new battery won’t catch fire, even if you drill through it.”

Although drilling would produce aluminum dust, which isn’t exactly benign. However, point taken.

Personally, I still prefer Continue reading →

Fixing climate change is profitable

Batteries are just one of many reasons, including electric vehicles, smart grid, solar and wind power (including pass HB 57 and you can profit by getting financing for your own solar panels), plus massive savings on health care and electricity bills; batteries are one of many reasons that fixing climate change will save us all money, clean up our air and water, expand our forests, preserve property rights, and make some people rich:

In fact, a recent report suggests that revenue from the distributed energy storage market — meaning battery packs and other storage devices located directly at homes and businesses (many of which now generate electricity through solar) — could exceed $16.5 billion by 2024. Another report predicts $68 billion in revenue in the same time frame from the grid-scale storage market. This includes large-scale battery packs, hydro-storage systems that use cheap abundant electricity to pump water uphill to drive turbines later on, or even solar thermal systems that store energy as heat in molten salt.

And it’s all happening fast, so fast your jaw will drop if you’re not paying attention. So let’s stop talking about the costs of fixing climate change. It’s not just no-cost and free, not just in the future but right now; we’re all actually going to be better off through fixing climate change: healthier and more prosperous.

Solar boom charts

When a power source grows 66% a year on average people start taking notice. Few had heard of the Internet in 1993: now it’s in your pocket. In less than a decade, by 2023, solar power will generate more energy than any other U.S. source. To keep Georgia from being left behind, this is the year to change a 1973 law.

If charts like this one aren’t familiar yet, they will be in the next year or two:

Tim McDonnell, Mother Jones, 7 November 2014, Here Comes the Sun: America’s Solar Boom, in Charts: It’s been a bit player, but solar power is about to shine.

At 66% more per year, solar power’s current 1% of U.S. electricity next year will be 1.66%, then 2.76%, then Continue reading →

Organic battery with no metals –Harvard SEAS

Solar already provides peak power at peak load, and through distribution is resilient, and that plus ever-decreasing prices will drive solar deployments up exponentially for a decade or so yet. If we add an inexpensive metal-free battery, solar will take over even faster. And that’s what Harvard’s School of Engineering and Applied Sciences has just published as a discovery.

Harvard SEAS PR of 8 January 2014, Organic mega flow battery promises breakthrough for renewable energy: Harvard technology could economically store energy for use when the wind doesn’t blow and the sun doesn’t shine,

The paper reports a metal-free flow battery that relies on the electrochemistry of naturally abundant, inexpensive, small organic (carbon-based) molecules called quinones, which are similar to molecules that store energy in plants and animals.

And much less expensive, reported CBC News 9 January 2014, Continue reading →

Which first to get more solar: fight big money or new technology?

In Georgia we’re still below 1% electric power generation from solar, and we can get to 20-30% with no new technology whatever. Georgia Power’s nuke overruns are already causing a reaction of still more distributed solar. Yet even that good news gets the usual reaction: “This is necessary but not sufficient: a breakthrough in energy storage technology is required.” Which just ain’t so; distributed rooftop solar alone is plenty to move Georgia way ahead. That’s why Edison Electric Institute calls distributed solar a massively disruptive influence on the utilities’ century-old cozy baseload model. What’s holding solar back is those same big utilities, who understandably don’t want to change their long-time cash cow. But they’re going to change, and pretty quickly.

People unfamiliar with the sunny south (which is most of the world south of, oh, Germany), still say things like this: Continue reading →

Cool solar gadget

We don’t even need new solar innovations for solar to take over most power generation through economies of scale, but we will start seeing more innovative solar gadgets like this one, leading to even more distribution of solar power.

Just stick this portable outlet to your window to start using solar power (by Sarah Laskow for Grist 29 April 2013)

We have seen a lot of solar chargers in our day. And among all of them, this is the first one we’ve seen that we will definitely run out and buy as soon as it’s made available in the U.S. It’s a portable socket that gets its power from the sun rather than the grid. You plug into a window instead of into the wall. It’s easy.

That was the whole point, according to the designers, Kyohu Song and Boa Oh: “We tried to design a portable socket, so that users can use it intuitively without special training,” they write.

It’s got solar panels, a plug, and batteries for 10 hours. It won’t run your air conditioner, but it will charge your phone.

Here’s another company’s take on the same idea from last year, and you can buy that one right now. Only in bulk, apparently. But stay tuned: we’ll see more ways to put solar chargers on your window, your car’s window, your car, your hat, etc….
