“Passive” wifi could pave the way for connected devices that run on nothing

“Passive” wifi could pave the way for connected devices that run on nothing

If wifi signals were like food — and, let’s be honest, they basically are when going more than a few hours without internet is tantamount to digital starvation — then so-called passive wireless devices would be like a quiet roommate who steals all your food and never pays for anything. Except, in a good way.

See, unlike the mooch who depletes your peanut butter supply one teaspoon at a time and offers guests tea from your stash, digital mooches are great. They don’t need batteries (that die) or power chords (that get lost), because they just harvest energy from the wifi signals already flying all around us. And when they want to send their own signals, they just deflect some of that already-airborne wifi, rather than generate their own — a task too energy intensive to do just on harvested power.

All told, devices — sensors or security cameras, for example — that partake in this kind of digital mooching could use up to 10,000 times less energy than most of today’s devices. You should probably read that again: All told, devices that partake in this kind of digital mooching could use up to 10,000 times less energy than most of today’s devices. So basically, they run on nothing.

Now, if this all sounds too good to be true, then check this out. Passive wifi was just named one of MIT Technology Review’s 10 breakthrough technologies of 2016. And if you still don’t believe it, then check this out — OK, that one’s just a mostly blank webpage, but it will be the home of Jeeva Wireless, a company gearing up to bring this passive wifi to the masses.

University of Washington professors Shyamnath Gollakota and Joshua Smith are developing the technology (along with the requisite graduate students behind almost all scientific and technological advances, of course). The group has already tested passive motion sensors, microphones, and a low-power video camera, and they’ve shown that deflected signals can travel up to 100 feet and through walls.

So as more and more of our devices join the Internet of Things Techno Jelly Net, we could be seeing fewer and fewer batteries and power cords. They won’t be gone completely, since the original signals have to come from somewhere — and that somewhere could be TVs, radios, or other wifi transmitters that tend to be plugged-in and stationary — but they could be largely gone from small, low-power devices.

It’ll likely take a few years for these digital moochers to become widely available. But just think: When they do, you could wire up your kitchen with passive cameras and sensors to catch you-know-who doing you-know-what.

Joy, Rage, and Love: ’80s-tastic Photos of San Francisco Pride

Mother Jones

I can’t remember exactly how we all ended up going to Gay Pride brunch together at my friend Marta’s house that Sunday morning, in June of 1988. In retrospect, it seems inevitable that I would bring along Saul Bromberger, a photographer at the East Bay newspaper where I was a reporter, and his then girlfriend and now wife, Sandra Hoover.

At the time, Saul and Sandy were already four years into a project that would last until 1990: documenting the San Francisco gay pride parade. It was the height of the AIDS epidemic, and anger at the world’s indifference to the disease was growing, generating radical groups like ACT Up (AIDS Coalition to Unleash Power). So Saul and Sandy came to our pride brunch with cameras in hand.

The pair started shooting the parades in 1984 because they believed they were witnessing history. “It was this kind of test I was giving myself: Can we document this movement that is also a parade?” Saul remembers. Unlike other photographers, he didn’t “just see people jumping around and dancing,” he says. He saw people “demanding change.”

Saul and Sandy wanted to capture the celebration, the love, and the rage, and in so doing, to capture the heart of a movement.

They purposely eschewed the long lenses favored by newspaper journalists, who seemed focused only on the spectacle. Instead, they got close to their subjects. They talked to them. They made friends. And the pictures they took were intimate and close.

But when Saul and Sandy asked to shoot the brunch (or maybe—I can’t remember to be honest—I invited them) they were putting me in a place I hated and loved at the same time.

A heads up: Some of these photos contain nudity.

This was a time when the gay world often existed separately from the straight one, and before cameras were everywhere. They needed permission to be there. We trusted them.

I also knew they had to be there. I wanted them there. I felt honored. But I also felt scared and exposed. My experience back in 1987 was that if you didn’t purposefully and repeatedly out yourself, you were not out. There was no social media where you could simply declare yourself to be something other than straight and then watch the consequences unfold.

You had to tell people over and over again. You had to make yourself the story.

It seemed easier not to do it. Besides, I was a journalist, an outsider. I covered the stories. I didn’t make them. Like Saul and Sandy, I’m an observer by nature.

It felt strange to thrust myself into the spotlight. I could alienate people. What if my sources stopped talking to me? It wasn’t just an idle concern. It happened. But it was more than that: Like most humans, I didn’t want to put myself in a box. I didn’t want to be other.

Just a few years before, in my early 20s, I had concluded that something inside of me was broken. I had great boyfriends. I just couldn’t fall in love. I had resigned myself to a life without love, when on a balmy night in my senior year of college, my female roommate and I stepped out onto the sidewalk and fell into a passionate kiss. Yes, I kissed a girl and I didn’t just like it. It rocked my world. I got it. And in that moment, I realized I was not broken. I was just different.

It was an intensely personal, intensely private discovery. But I quickly understood that if I were to date people of my own gender, I would be taking a political stand, like it or not. I couldn’t remain a detached observer.

So when I went to the pride parade, it wasn’t just to party. I went because, like so many others, I needed it.

I needed to fuel up on all the pride, all the love, all the righteous anger, all the togetherness. It was an infusion on which I could draw during the year. When someone yelled “dyke” at me and my girlfriend in the street, or a friend suddenly shunned me, or a relative told me that they didn’t understand but still loved me even if I was wrong, I could tap into that reserve.

Recently, I was talking with Saul about those years. He seemed miffed at himself for not putting his work out there: Every year they’d go to the parade, take amazing photos, and develop them. They’d hand out these beautiful prints to their subjects. They’ve always been generous like that. My halls were lined with them.

But then they’d go in a box under the bed.

“There were a lot of pictures I took back then that I never submitted to the paper because I thought they were personal,” Saul says.

Surely they could have gotten them out before. Surely, they would have gained notoriety for capturing a movement in advance of everybody else. I’ve been thinking about that: Why didn’t they bring these pictures out?

I think I know. I think in a way they kept them in a box for us. To protect the community from a world that could be hostile and cruel.

These pictures show something soft and vulnerable. They show humanity. But they also show nudity. It would be easy to take them out of context.

And to bring them out into the glare of society where they could be ridiculed—maybe they didn’t belong there. Not yet.

When we recount history, inevitably we reshape it, sharpening memories with new revelations and forgetting other parts altogether.

But these pictures capture unflinching, static moments of a different time. There’s a picture of a bare-breasted woman carrying a whip. There’s a picture of a couple on a roof with their trusty dog. There’s a picture of five men in a window, three of whom I know for sure died of AIDS.

The past lives and breathes in these photos. And it’s important to remember history. It’s important to see ourselves from a distance, especially when the closet walls have fallen and here we are.

The Opportunity To Save Money With Solar Panels

More and more people these days turn to the solar panels as a great alternative energy. According to the recent studies, those who have installed them soon, greatly benefit of this green energy, as some governments started to subsidize this initiative.

The fact that you can use the electricity for free after the initial period of investment makes these green sources lucrative and advantageous for a great number of home and business owners. It is believed that solar panels and other alternative energy sources will completely substitute the conventional grid used today.

Read here about some of the greatest benefits that solar power may offer you, being the way forward.

The world population increases each and every day currently being over 7 milliard people. As a result, the demand for electricity increases enormously every day, while the fossil fuel supplies are limited and are about to be completely run out. This leads to the electricity prices’ escalation, causing difficulties for customers who find it more and more challenging to afford paying for these costs. In addition, the high prices of electricity lead to increase of other products’ prices too.

If you take advantage of the opportunity to install your own solar system, you will rely on yourself only, which many business owners prefer today. The amount you will pay for the electricity will significantly be reduced compared to your current bills from the conventional grid usage. This means you will be able to save money.

Even though some people do not choose alternative energy sources because of their equipment’s high costs, the investment will surely repay you in just a few years and you will start earn money after that period. Additionally, this is low-risk investment compared with other investments made today, such as stocks or bonds.

If you turn to an expert in this field, he will be able to calculate precisely your returns after using this kind of energy. You will learn the amount you are going to save lifetime after installing a solar panel, which will motivate you to do that right away.

In addition, the price of your property is going to increase, if it has low carbon content, as it is in demand today. In case you intend to sale your house after several years, then buying and installing solar panels is going to greatly benefit you by increasing the selling price. You will not only benefit yourself, but others as well, because the solar systems you choose contribute to the environment welfare.

If you are concerned about the environment and all things that are harmful for both our world and us, you will definitely choose the alternative energy sources, as they not release byproducts and save the air and nature from pollution.

The renewable energy is unlimited, so you will not worry that it might run out soon. This makes it great investment for future for you and your children and grandchildren. There are three types of solar panel installation: roof, ground mount and installation on other structures. The most preferred and the cheapest one is the roof mount, so you also can choose it for yourself.
