The film Back to the Future II takes place mostly in the future of 2015. With only two years left before the rest of us get to experience that future, it seems like a good time for an audit. Granted, some of the predictions made in the film were a little over the top (but who knows, maybe hipsters will make double ties popular). While I'm still waiting for my hoverboard, many of the predictions made in the 1989 classic actually came true.
10. Handheld computer tablets
Remember that funny little thing called the iPad that came out in 2010? You know, that device that revolutionized personal computing? In this scene a member of the Hill Valley Preservation Society tries to get Marty to donate money using a handheld computer. If anything, the version shown in the movie looks more clunky that the tablets of today. Looks like that prediction passed. Now go do something awesome with your tablet like save historical sites, or play Candy Crush.
9. Flat screen TVs
Not only do we have flat screens, but many different satellite and cable providers let you watch multiple shows at once. And not just on our TV, with the internet and streaming services we can watch multiple shows on our computer, our TV, or even on our tablet or smartphone.
8. Video billboards
In Back to the Future’s world of tomorrow, video advertisements are everywhere. With new LED billboards, this is rapidly becoming a reality. Now if we could only have holograms.
7. Small, thin cameras
I doubt if many people imagined just how much cameras would be a part of our everyday lives. Not only do we have tiny digital cameras, we even have cameras in our phones and tablets. Doc Brown’s camera seems a bit outdated in comparison. But, maybe he’s trying to be retro.
6. Video conferencing
Back to the Future was one of many films and shows made during the 80s and 90s that predicted video communication. Thanks to programs like Skype, it’s not only possible, it’s available on everything from your TV to your tablet to your smartphone. They did get it wrong with fax machines though, which were popular just about as long as laser disks and pagers. Too bad they couldn't see email comming.
5. Voice Controlled Computers
Marty orders a Pepsi from a robotic computer screen when he stops by Café ‘80s. Thanks to dozens of different computer applications, most recently Siri, that has become a reality. What doesn’t make sense is why you would want an ‘80s themed diner.
4. Computer/TV Visors
At the future McFly residence, both Marty and Marlene watch TV on personal visors. They can also tell when someone is calling and who it is from the same device. While TV glasses have made several attempts at being popular, they haven’t ever seemed to get very far. Google is trying to change that with Google Glass, which will allow you to get directions, do video conferencing, watch videos, surf the internet, record videos, and more.
3. 3D Videos (and ridiculous amounts of sequels)
They might not be holographic, but 3D movies are a definite reality today. But only time will tell if they are here to stay or nothing more than a passing fad. One thing is for sure, ridiculous amounts of sequels are popular. Just look at how popular movies like Saw 7 (in 3D) and Fast and Furious 6 have been.
2. Game Controls
When Marty goes to Café '80s he meets two kids and decides to show off by playing the Nintendo game Wild Gunman. But, young Frodo and his friend are unimpressed. “You mean you have to use your hands?” they exclaim, “That’s like a baby’s toy!” Whatever technology they hinted at might have been beyond what most people could have dreamed up back then, but today its commonplace. Devices like the Microsoft Kinect not only allow you to use your whole body as a controller, now even your voice is used to control your Xbox.
1. Flying Cars
Okay, this one is a bit of a stretch. It’s true that flying cars aren’t as common as portrayed in the movie, but the concept of a flying car has been in the works for quite a few years now. The Moller Skycar is one of many prototypes that is aimed at being a means of transport for anyone who can drive.
A surprising number of 1980s predictions actually did come true, and some of them have even been better than what Hollywood was able to dream up. All we need now is the hoverboard.

An Iranian filmmaker, Bahram Sadeghi, uploaded a video Thursday of himself calling the National Security Agency (NSA) hotline in a sarcastic attempt to retrieve an email he told the operator he accidentally deleted.
“A couple of days ago I received an email and by mistake I deleted it, the email… permanently,” Sadeghi can be seen explaining to an NSA employee over the phone.

“A couple of days ago I received an email and by mistake I deleted it, the email… permanently,” Sadeghi can be seen explaining to an NSA employee over the phone.
The filmmaker then explains to the operator assisting him that he went to a computer store to recover the supposed email, but they were unable to do so. According to him, they suggested he call the NSA.
“This is something we wouldn’t actually be able to help you with,” replies the NSA employee.
Sadeghi then informs the unidentified employee that he is Iranian and suggests as a result he may be monitored more heavily by the NSA.
While the NSA said they were unable to help Sadeghi, they can be heard asking him for his personal contact information in the roughly five minute video.
The video had a little over 74,000 views at the time of publication.

Retired TV station owner and broadcast engineer, John Kanzius, wasn't looking for an answer to the energy crisis. He was looking for a cure for cancer." Sounds great, but Stan Meyer ended up dead somehow in the 90s when he invented his famous water powered car. I hope this guy lives long enough to get this invention into production.

Researchers at Harvard University have created the first noninvasive brain-to-brain interface (BBI) between a human… and a rat. Simply by thinking the appropriate thought, the BBI allows the human to control the rat’s tail. This is one of the most important steps towards BBIs that allow for telepathic links between two or more humans — which is a good thing in the case of friends and family, but terrifying if you stop to think about the nefarious possibilities of a fascist dictatorship with mind control tech.
In recent years there have been huge advances in the field of brain-computer interfaces, where your thoughts are detected and “understood” by a sensor attached to a computer, but relatively little work has been done in the opposite direction (computer-brain interfaces). This is because it’s one thing for a computer to work out what a human is thinking (by asking or observing their actions), but another thing entirely to inject new thoughts into a human brain. To put it bluntly, we have almost no idea of how thoughts are encoded by neurons in the brain. For now, the best we can do is create a computer-brain interface that stimulates a region of the brain that’s known to create a certain reaction — such as the specific part of the motor cortex that’s in charge of your fingers. We don’t have the power to move your fingers in a specific way — that would require knowing the brain’s encoding scheme — but we can make them jerk around. Which brings us neatly onto Harvard’s human-mouse brain-to-brain interface. The human wears a run-of-the-mill EEG-based BCI, while the mouse is equipped with a focused ultrasound (FUS) computer-brain interface (CBI). FUS is a relatively new technology that allows the researchers to excite a very specific region of neurons in the rat’s brain using an ultrasound signal. The main advantage of FUS is that, unlike most brain-stimulation techniques, such as DBS, it isn’t invasive. For now it looks like the FUS equipment is fairly bulky, but future versions might be small enough for use in everyday human CBIs. (See: Real-life Avatar: The first mind-controlled robot surrogate.)
With the EEG equipped, the BCI detects whenever the human looks at a specific pattern on a computer screen. The BCI then fires off a command to rat’s CBI, which causes ultrasound to be beamed into the region of the rat’s motor cortex that deals with tail movement. As you can see in the video above, this causes the rat’s tail to move. The researchers report that the human BCI has an accuracy of 94%, and that it generally takes around 1.5 seconds for the entire process — from the human deciding to look at the screen, through to the movement of the rat’s tail. In theory, the human could trigger a rodent tail-wag by simply thinking about it, rather than having to look at a specific pattern — but presumably, for the sake of this experiment, the researchers wanted to focus on the FUS CBI, rather than the BCI.
Moving forward, the researchers now need to work on the transmitting of more complex ideas, such as hunger or sexual arousal, from human to rat. At some point, they’ll also have to put the FUS CBI on a human, to see if thoughts can be transferred in the opposite direction. Finally, we’ll need to combine an EEG and FUS into a single unit, to allow for bidirectional sharing of thoughts and ideas. Human-to-human telepathy is the most obvious use, but what if the same bidirectional technology also allows us to really communicate with animals, such as dogs? There would be huge ethical concerns, of course, especially if a dictatorial tyrant uses the tech to control our thoughts — but the same can be said of almost every futuristic, transhumanist technology.

Ever fancied an off-road vehicle that can transform into a boat in less than 15 seconds? Of course you have. And now you can actually buy one, as amphibious vehicle manufacturer WaterCar presents the Panther--a Jeep based off-roader that can swim.
Amphibious vehicles are hardly a new idea; the original stems back to 1961 with the German-built Amphicar that sold an estimated 3,872 vehicles before the company eventually went under (excuse the pun).
Others, too, have arrived, including the Gibbs Aquada that Sir Richard Branson piloted to set the record for the fastest crossing of the English Channel by an amphibious vehicle back in 2004. Gibbs are now rushing to see its Sport Quadski vehicle make production by the end of the year.
But for Californian company WaterCar, the day that consumers can actually buy a reliable amphibious vehicle is already here. It took 14 years to turn the idea of a purchasable product into reality. Back in 2010, the company entered the Guinness World Record Books as the fastest amphibious car with its Python model, but making the Panther a car that could comfortably handle activities on road as well as on water, while maintaining a machine that's serviceable by most skilled auto/marine mechanics, was a painstaking process.

A free energy device is one that creates energy in an open system. This means that the physical device is open to take energy from around it’s environment. Our educational institutions and mainstream science have perpetuated the idea that these systems cannot be created. In order to uphold and maintain a system of belief, one must teach it. People are waking up to the fact that not everything on planet Earth is as it seems, and new truths are starting to infiltrate the consciousness of the masses. It is very likely that free energy devices do exist and like many other discoveries, they have been concealed and hidden from the human race.
The energy is extracted from what we call ‘space time’, it’s the energy all around us that we can’t see. A device like this cannot have a meter on it, it can’t be measured and no price tag can be put on it.
This can mean that a free energy device is a threat to the industry that controls our world and the people on it, the energy industry. The energy industry dictates who has access to life and who doesn’t. If you look at where the funding comes from, it’s easy to make connections between the energy, pharmaceutical, health, food and educational industries. Let’s take a look at what has been concealed from us and what’s becoming increasingly transparent. Below are two clips from the documentary “Thrive” that illustrate the implications of this device, and the effort involved to suppress it.
Foster Gamble is an heir and direct descendant of James Gamble of Procter and Gamble. From a young age he was expected to be apart of the hierarchical establishment that is in control of the worlds resources, but he chose a different route. This is a minuscule amount of evidence within the public domain that supports the idea of free energy devices, if you are interested hopefully it shows you that there is much more to this phenomenon and inspires you to do your own research. It’s always good to have an open mind.
Although new technologies can help transform our world, the real change lies within each one of us. It’s us that hold the key to change, no technology can transform this planet until we operate from our true natural state. A state of love, peace, understanding and cooperation are required if we want to move on from this current Earth experience and create something new for ourselves.

A German student has built an electromagnetic harvester that recharges an AA battery by soaking up ambient, environmental radiation.
These harvesters can gather free electricity from just about anything, including overhead power lines, coffee machines, refrigerators, or even the emissions from your WiFi router or smartphone.
This might sound a bit like hocus-pocus pseudoscience, but the underlying science is actually surprisingly sound. We are, after all, just talking about wireless power transfer — just like the smartphones that are starting to ship with wireless charging tech, and the accompanying charging pads.
Dennis Siegel, of the University of Arts Bremen, does away with the charging pad, but the underlying tech is fundamentally the same. We don’t have the exact details — either because he doesn’t know (he may have worked with an electrical engineer), or because he wants to patent the idea first — but his basic description of “coils and high frequency diodes” tallies with how wireless power transfer works. In essence, every electrical device gives off electromagnetic radiation — and if that radiation passes across a coil of wire, an electrical current is produced. Siegel says he has produced two versions of the harvester: One for very low frequencies, such as the 50/60Hz signals from mains power — and another for megahertz (radio, GSM) and gigahertz (Bluetooth/WiFi) radiation.
The efficiency of wireless charging, however, strongly depends on the range and orientation of the transmitter, and how well the coil is tuned to the transmitter’s frequency. In Siegel’s case, “depending on the strength of the electromagnetic field,” his electromagnetic harvester can recharge one AA battery per day. He doesn't specify, but presumably one-AA-per-day is when he’s sitting next to a huge power substation. It makes you wonder how long it would take to charge an AA battery via your coffee machine, or by leeching from your friend’s mobile phone call.
As a concept, though, Siegel’s electromagnetic harvester is very interesting. On its own, a single harvester might not be all that interesting — but what if you stuck a bunch of them, magnetically, to various devices all around your house? Or, perhaps more importantly, why not use these harvesters to power tiny devices that don’t require a lot of energy? Sensors, hearing aids (cochlear implants), smart devices around your home — they could all be powered by harvesting small amounts of energy from the environment.
One question does remain, though: How much ambient, wasted electromagnetic radiation is actually available? There are urban legends about people who install coils of wire in their garage, and then suck up large amounts of power from nearby power substations or radio transmitters. Would the power/radio company notice? Would it degrade the service for other people? Is this a likely plot for Die Hard 6: A better day to die hard?

Circular Pedestrian Bridge and overpass, which allows people to avoid the roundabout traffic of Lujiazui Road. The Oriental Pearl Tower can also be accessed from this bridge to connect people to cafes, shopping malls, office buildings and a transit station. Built nearly 20 feet above the street, the pedestrian bridge has many escalators and stairways for entrances and exits and because of the contemporary design, the long spans between each column allows people on the street level to have a pleasant viewing experience.
