Leg Brace Harvests Energy


Time Magazine has just named the Bionic Energy Harvester, which was developed by researchers at Simon Fraser University, as one of its Top 50 Inventions of 2008. The device is a wearable orthopedic knee brace that extracts up to 13 watts of power. One minute of walking will generate about half an hour of talking on a mobile phone.

Bionic Power is the spinoff company from SFU, a university based in Burnaby, Canada. “Every day we move closer to the goal of turning this great idea into a product that will improve the lives of soldiers, first responders, users of mobile medical devices, and other people whose lives depend upon portable power,” said the company's CEO Yad Garcha.

The device, first unveiled in the journal Science last February, is powered from the energy put into slowing down the knee joint at the end of each person's step. The process is similar to the regenerative braking found in hybrids. Commercial applications could make it possible to self-power prosthetic limbs or medical implants.

While the brace is years away from getting on the commercial market, the Canadian military is testing the prototype next spring. Eventually the goal is to make it smaller and lightweight. The military prototypes will be about half the weight of the device first tested earlier this year.

Time Magazine listed the Bionic Energy Harvester at 33 in its Top 50 list calling the device “perhaps the most promising in a class of products that harvest energy - all the more important at a time when portable tech, from Blackberries to iPods, is becoming ubiquitous.”

Using Eel Cells to Create Electricity

The biggest eels can produce charges up to 600 watts of electricity, enough to power your computer, monitor, printer and office lighting simultaneously...at least for a moment. Knowing that some of the best ideas come from nature, researchers at Yale University working with counterparts at the National Institute of Standards and Technology are applying what eels do naturally to artificial cells.

Jian Xu, a postdoctoral associate in Yale's Department of Chemical Engineering, said the electric eel is very efficient at generating electricity. “It can generate more electricity than a lot of electrical devices.” The goal is to replicate electric eel cells in an artificial version to act as a power source for medical implants. Electric eels have specialized cells called electrocytes to channel the output of electricity the same way that nerve cells fire up.

The researchers from Yale had previously created a blueprint of an artificial cell that turned out to be even more efficient than eels at producing electricity.

One of the designs for the artificial cell generates more than 40 per cent more energy in a single pulse than a natural electrocyte. Another could produce peak power outputs over 28 percent higher.

The researchers hope to eventually use the artificial cells for bio-batteries and are ideal, if they work, for medical implants because they release no toxins.

YoYo Powered iPhone Charger?

Why the heck not right? I mean, YoYos are a very efficient way of generating power, and iPhones don't really need all that much power to charge. So what's the problem with this idea?

I'd even say that it's several times cooler, more convenient, and better for the environment than a solar powered charger. What remains to be seen is whether or not you can actually get enough power out of one of these things to charge your phone easily. Of course, no one wants another thing to carry around. Which makes me think...why not just put the phone inside the YoYo!

Inhabitat is treating this thing like it will actually exist soon, but I'm not so sure about that. It seems like a pretty design project to me...a joke even. Big cues that it's not coming to market any time soon include the Apple logo on the device (which would never be allowed for a real design project.)

But that doesn't mean it's not a good idea...and we certainly hope that this and other human-powered charging devices will make our mobile future more convenient and more sustainable.

Self-Powered Light Switch Has No Wires

There's a new way of wiring your lights...and it doesn't involve wires. Pretty freakin' cool actually. Right now, your light switch has a physical connection to your light. When you flip the switch, a circuit is completed and the light turns on.

But connecting every light to every light switch basically requires twice as much wiring for a house's lighting system. That's just dumb.

Since the advent of remote control, people have been trying to figure out a way to have a light switch turn a light on and off without having to be physically connected to the light. Unfortunately, this has always required some kind of battery (to power the remote) and that battery would invariably die.

But now, EnOcean (a company that specializes in pulling power from ambient sources) has figured out a way to have the light switch be powered by you.

Every time you flip the switch, a tiny generator creates a tiny charge. That tiny charge powers a tiny remote control that sends out a tiny signal that can be received by the light. All from the "power" of your flipping. Pretty cool.

The first adopters of the technology will be folks looking to retrofit old (possibly historically significant) buildings. But peel-and-stick, no-wiring-needed electronics are needed everywhere...and having them be self-powering is a true green innovation.

2 Million New Jobs by 2010 with Green Investment

The green movement just might be the solution our flagging economy needs. A new report by the Natural Resources Defense Council discusses how the US can create 2 million new jobs in 2 years by investing in clean tech.

The real clincher for greenies is that the report shows that green investing will create four times as many new jobs as the same amount of investment in oil. The amount of investment analyzed was $100 billion, which isn’t outrageous considering the hundreds of millions already going into clean tech by different companies, foundations, and even the DOE. The report notes that this could also include auctions of carbon permits with the cap-and-trade system.

The jobs would be nationwide in fields that already exist – construction workers would be employed to set up wind and solar farms, engineers would be employed for site and product design, etc.

Two millions jobs and serious investment in clean energy tech are both deeply needed. The report shows it’s an awesome possibility. Hopefully politicians and leaders are listening.
