UCI doctoral candidate Mya Le Thai has developed a nanowire-based technology that allows lithium-ion batteries to be recharged hundreds of thousands of times.

There's an old saying that luck happens when preparation meets opportunity.

There's no better example of that than a 2016 discovery at the University of California, Irvine, by doctoral student Mya Le Thai. After playing around in the lab, she made a discovery that could lead to a rechargeable battery that could last up to 400 years. That means longer-lasting laptops and smartphones and fewer lithium ion batteries piling up in landfills.

A team of researchers at UCI had been experimenting with nanowires for potential use in batteries, but found that over time the thin, fragile wires would break down and crack after too many charging cycles. A charge cycle is when a battery goes from completely full to completely empty and back to full again.

But one day, on a whim, Thai coated a set of gold nanowires in manganese dioxide and a Plexiglas-like electrolyte gel.

"She started to cycle these gel capacitors, and that's when we got the surprise," said Reginald Penner, chair of the university's chemistry department. "She said, 'this thing has been cycling 10,000 cycles and it's still going.' She came back a few days later and said 'it's been cycling for 30,000 cycles.' That kept going on for a month."

This discovery is mind-blowing because the average laptop battery lasts 300 to 500 charge cycles. The nanobattery developed at UCI made it though 200,000 cycles in three months. That would extend the life of the average laptop battery by about 400 years. The rest of the device would have probably gone kaput decades before the battery, but the implications for a battery that that lasts hundreds of years are pretty startling.

“Mya was playing around, and she coated this whole thing with a very thin gel layer and started to cycle it,” said Penner added. “She discovered that just by using this gel, she could cycle it hundreds of thousands of times without losing any capacity.”

“That was crazy,” he added, “because these things typically die in dramatic fashion after 5,000 or 6,000 or 7,000 cycles at most. ”"The big picture is that there may be a very simple way to stabilize nanowires of the type that we studied," Penner said. "If this turns out to be generally true, it would be a great advance for the community." Not bad for just fooling around in the laboratory.

Since her discovery, Mya Le Thai has gone on to a successful career as the Principal Scientist with the Enevate Corporation,

Portrait of Matthieu Ricard

Matthieu Ricard, often called "the happiest man in the world," says that the way for all of us to live sustainably on this planet is to adopt a culture of thinking about each other. And not just the others who are here right now, but also people we'll never meet.

He tells us some stuff that you're probably tired of hearing. We're exhausting our planets resources. Humanity has completely screwed everything up on this planet.

But stick around because he's going to get crazy surprising.

This is not a speech about recycling.

He points out that our situation is even more serious than you might have known. We're rapidly exceeding the planetary boundaries that make Earth habitable.

And, let's be honest, it's easy not to feel crazy urgent about this, right?

When we consider how we treat our planet, when we're talking about big action, we're doing it because we'd like our kids and grandkids to not live in a post-apocalyptic hellscape.

But then he offers a solution.

And it's not about buying a Prius.

So, his big revolutionary advice is just to look out for each other but in a tremendous way. Look out for your neighbor. Look out for your friend. Look out for your enemy and their great-great-great-grandkid.

But is that possible? And can we be happy if we think about others that much?

In fact, it happens all the time. So often that it's not newsworthy. This ordinary goodness is what helps communities and families grow.

An international survey found that the very most perfect predictor of happiness is the quality of human relationships.

But what is altruism? Is it a choice? Is it something we do for ourselves so that we will feel good about ourselves?

But how do we encourage that impulse to grow within ourselves, our communities, and our children?

For that, you'll have to watch the video.

We all want the world to be better and what better place to start than at home? Enter: Wildgrid, an all-female team providing education and empowering women to “electrify” their homes.

Why women? Women make 91% of ALL decisions in their households. And that’s no small thing when it comes to sustainability – 20% of all carbon emissions are from our homes! Electricity, gas-burning stoves, furnaces, hot water heaters, and many more – all of these everyday appliances make a big difference in how eco-friendly our homes are.

So what is the fastest way to make major reductions in household carbon emissions? Educating and empowering women!

Creating a more energy-efficient home – called electrification – is a process that can often feel confusing and overwhelming, particularly to folks who are often marginalized in male-dominant spaces.

“In spaces with men where this kind of topic is being covered, I find myself feeling [overwhelmed]... I found it really great that it was for women,” said one Wildgrid user who took Wildgrid’s women-only education course, Voltage Vixens.

Wildgrid’s online tool is simple, intuitive, and requires no previous background in sustainability to understand. To calculate all the rebates you qualify for, visit WildgridHome.com.

Here's something you may not have known: In 2008, we grew enough food for 11 billion people.


(Reminder: There are just over 7 billion humans here on Earth.)

But half of that food went to feeding animals (you know, so we could eat them). And a great deal also went to fueling cars.

Clearly, we're not hurting when it comes to our ability to grow food. But how we grow that food matters. In the industrial system that feeds much of the globe, it takes 10 calories of fuel to produce one calorie of food.

Which, let's be honest, is not the most efficient process. That's why so many people are keen on growing food organically — by which Wikipedia tells me means:

In other words, organic farming involves growing food more naturally with fewer resources. But here's a good question: Can organic food feed the world?

Allow me to quote noted food expert Michael Pollan:

"In industrial areas, organic [farming] achieves 92% of the yield of industrial [farming]. But you go to the developing world, and it produces 182% of current yield."

Not too shabby, eh? Maybe there's some hope for our food system after all.
