New Photon Thruster: Get to Mars in 1 Week!

An interesting new patent pending design for a photon thruster appears to be the real deal. Check out the article and who is behind it. (A fellow SRI alumnus!). Getting to Mars in a week means getting to the moon, as well as other nearby planets would be quite fast as well. This could be quite revolutionary.

TUSTIN, Calif., Sept. 7, 2007 -- An amplified photon thruster that could potentially shorten the trip to Mars from six months to a week has reportedly attracted the attention of aerospace agencies and contractors.

Young Bae, founder of the Bae Institute in Tustin, Calif., first demonstrated his photonic laser thruster (PLT), which he built with off-the-shelf components, in December.

A Passenger's Bill of Rights -- Sign me Up!

Where do I sign up to support this initiative? A group of exasperated US airline passengers who were stuck on the tarmac for 10 hours last month have come up with a proposal for a bill to establish a Passenger's Bill of Rights, which would include the following provisions:

Establishing procedures for airlines to return passengers to a terminal gate after three hours on the tarmac.

Requiring airlines to respond to complaints within 24 hours and resolve them within two weeks.

Forcing airlines to publish a list of chronically delayed flights online.

Compensation for bumped passengers or passengers whose flights are delayed by more than 12 hours at 150 percent of the ticket price.

Compensation for passengers whose baggage is lost or mishandled.

Creation of a Passenger Review Committee made up of nonairline consumers to review and investigate complaints.

Having been in situations like this myself I can attest to the fact that something has to be done about this. Last summer I was stuck on the tarmac in Texas in 120 degree heat. The plane's air conditioner was turned off because they wanted to conserve fuel, so inside the plane it was probably 130 degrees. To top that off nobody could get up, and the crew had to remain seated as well so they couldn't even bring people water. This lasted for 2 hours. I was almost passing out -- I can only imagine what it must have been like for children, the elderly or people with medical conditions. Airlines treat passengers only a little better than baggage, and that is not saying much! Something needs to be done about this and I'm glad an initiative is forming to take action. Count me in!

A Problem with Space Travel

As the distance a spaceship travels through space increases, so do the odds that it will collide with debris in its path – such as interstellar dust, micrometeorites, asteroids, dark matter, dark stars, etc.

If you are traveling at super high-speed, through uncharted territory, there is no way to know what is out there.

Even if it is charted territory, debris is always flying through – sometimes at incredibly high speeds. Especially when you near solar systems, or in denser areas.

It should be possible to say that after a certain distance the odds are 100% that a spaceship will experience a fatal collision.

As a result, only short range space travel is probably safe enough to be feasible unless some kind of shield technology is invented that can withstand the  blasts that result from collisions with even tiny things at such high speeds.

My guess is that if advanced interstellar civilizations exist, they do not travel linearly through space because it is just too dangerous. They must have a way to "tunnel" – either by using or creating wormholes, or some other means of teleportation, or hyperdimensional travel.

In speaking about this, my friend Josh, suggested the following:

Yeah- and here's another aspect to that problem.

Assume you are using a near light speed drive to go from star to star.

Any detection system you are using (radar, etc) will only extend slightly in front of the ship- because it is only moving slightly faster than you are- and the faster you go, the less time you have to detect and deal with obstacles or objects.

If you are moving slowly- perhaps a generation ship or a "frozen cargo" scenario- you could use radar connected to an autopilot- but you still need something to protect you from micrometeorites and interstellar dust- maybe a big electrostatic shield extending far in front of the ship that will attract and deflect such objects (most meteroids are ferromagnetic, so they respond well to electromagnetic fields...)

You really need a rapid response detection system...

Location Awareness -- The Next Big Thing

Japanese cell phone company KDDI is offering a new GPS-enabled 3D navigational tool to their 17 million subscribers (see article and picture). Their system helps consumers navigate city streets and even within buildings, using an innovative 3D map and audio directions. This system is similar to (but possibly more advanced than) the in-car navigation systems we are familiar with, such as Hertz "Neverlost" or the Magellan products (note: I have a Magellan aftermarket nav system in my car -- it's one of the most useful things I ever bought!).

GPS-enabled mobile devices and the location-aware services they enable are definitely a "Next Big Thing" contender.  They have many compelling potential uses in the near-term and mid-term future. Below are some of my wild speculations on how this technology could be used:

• Personal navigation. Your device can help you find your way when walking, driving, or even on the water or in the wilderness.
• Location-aware advertising. Your device can get special offers from stores near you, as you walk or drive around, according to your permissions, preferences and profile of course.
• Location-aware storage, search and retrieval. Your device remembers where you were when you wrote a note, took a photo, or sent a message.You can later search for your stuff based on where you were -- for example, "photos I took in Brazil" or "Notes I made at PC Forum in 2006" (for the best example of this, see the amazing product, EverNote -- the next version of which I got to preview recently, it is mind-blowingly cool!).
• Location-aware photo-enhancement. When you take a photograph it is not only tagged with time and location where it was taken, but the content of the photo can be automatically tagged based on the orientation of the camera. For example, if you take a photo of the Empire State Building, your camera will someday be able to tag the photo as being about the Empire State Building, and can even detect and tag the shape of the building itself in the photo.
• Location-aware social networking. Your device can track people nearby who are your friends, family, colleagues, or who match your interests and want to meet you (for example: dating). This can be useful to find people at a crowded event, or to hook up with your friends while out on the town, or to meet people at a trade show or conference.
• Location-aware personal security. Your device can keep a transcript of your movements on a server. Parties you authorize can track you if they need to find you immediately, or in case you go missing. In addition, bulk alerts can be sent to people who happen to be in particular areas -- for example, if a tornado is coming, people who happen to be in that vicinity can be warned.
• Location-aware information services. You can get news and other local info about the place you happen to be in. If you are standing outside a restaurant you can see reviews and discussions from people who have been there before. If you are already in the restaurant you can see recommendations of what to order from people who were there before you. Information can be virtually posted to particular places or regions -- you can hang a virtual post it note in your doorway so that anyone who passes through it gets the note.

New Quantum Propulsion Being Researched By Air Force

A radical new form of propulsion is being researched that may enable travel from Earth to Mars in 3 hours, and travel to nearby stars in just 80 days. The system is based on a novel quantum theory termed Heim quantum theory (HQT).

The hypothetical device, which has been outlined in principle but is based on a controversial theory about the fabric of the universe, could potentially allow a spacecraft to travel to Mars in three hours and journey to a star 11 light years away in just 80 days, according to a report in today's New Scientist magazine.

The theoretical engine works by creating an intense magnetic field that, according to ideas first developed by the late scientist Burkhard Heim in the 1950s, would produce a gravitational field and result in thrust for a spacecraft.

Also, if a large enough magnetic field was created, the craft would slip into a different dimension, where the speed of light is faster, allowing incredible speeds to be reached. Switching off the magnetic field would result in the engine reappearing in our current dimension.

The US air force has expressed an interest in the idea and scientists working for the American Department of Energy - which has a device known as the Z Machine that could generate the kind of magnetic fields required to drive the engine - say they may carry out a test if the theory withstands further scrutiny.

Professor Jochem Hauser, one of the scientists who put forward the idea, told The Scotsman that if everything went well a working engine could be tested in about five years.

However, Prof Hauser, a physicist at the Applied Sciences University in Salzgitter, Germany, and a former chief of aerodynamics at the European Space Agency, cautioned it was based on a highly controversial theory that would require a significant change in the current understanding of the laws of physics.

It is interesting to note that this theory shares a similar physical picture, namely a quantized spacetime, with the recently published loop quantum theory (LQT) by L. Smolin, A. Ashtektar, C. Rovelli, M. Bojowald et al. [11, 24-28]. LQT, if proved correct, would stand for a major revision of current physics, while HQT would cause a revolution in the technology of propulsion. (Source)

TV2Me -- "Space-Shifting" of Local TV Broadcasts

My friend Ken Schaffer's startup, TV2Me, is starting to really push the envelope on video streaming. Their box enables you to stream your own cable, satellite or terrestrial TV signal to your laptop or cell phone or PC, no matter where you are, with incredible fidelity. You hook up their component to your cable box at home and then you can login to your signal over the Net from anywhere. On the receiving end (for example on your laptop) you just install the TV2Me signal processing plugin for your browser and you can start watching full-screen live TV, streamed from your house, with the ability to change channels instantly, etc -- as if you were operating your TV from your home remote. It's possibly one of the best streaming technologies I've seen. I've used their private demo and it's amazing to watch live TV from cities all around the world on my laptop, even over a wireless router when on the road. We're not talking postage stamp sized streaming here, folks -- this is full screen and very crisp. And the buffer time is incredibly short as well -- it starts up almost immediately.

From what I can see their technology is way more advanced than the Slingbox. Not only that but the TV2Me box has the potential to be miniaturized and made even cheaper than the Slingbox. All in all this is a hot technology to watch. I could see this being built-into every cable box in the future as an additional service that cable box providers could sell to their customers. But there are many other uses of this as well -- for example keeping up with home news and sports when on the road, or for always catching those crucial HBO series episodes you just can't stand to miss. So many people spend so much time on the road for work -- TV2Me is a nice way to bring a little bit of your home with you wherever you go.

Here's their latest press release:

The World's Longest TV Show?

It wasn’t quite the level of Lucky Lindy's 1927 flight from Roosevelt Field to Le Bourget, but it was another trans-Atlantic first: On Sunday,
16 October, on El Al flight 01, non-stop from Tel Aviv to New York, private passenger Avner Teller, acting on his own initiative, watched live hometown Tel Aviv TV all the way to Kennedy.

Television reception from Tel Aviv was made possible by TV2Me®, an extraordinary system that allows viewers to "space shift" any city's full range of cable or satellite television stations anywhere on — or off — the earth.

Time Traveler Convention and Further Thoughts

There's a very interesting event taking place at MIT tonight -- the first (and only?) Time Traveler Convention. The organizers are inviting anyone in the future who is capable of time travel to travel back to the geo coordinates of this event (to be held at MIT) and attend it, along with proof that they are from the future. In order to increase the chances that this event will be discovered by the relevant people in the future, the organizers have asked as many people as possible to link to the event and have also asked people to insert acid-free paper containing the coordinates of the event into library books that are likely to be read in the future.

This event is an experiment that attempts to test whether in fact time travel will be invented in our future. The hypothesis is that if time travel is possible, and if it is discovered, and if future time-travel-capable beings also find out about this MIT Convention, then they will travel back in time to the event. Of course this begs the question of whether they actually would attend this event even if they could -- for example, perhaps they prefer to remain secret at this time? Or perhaps if they prove to us that time travel is possible at this moment in our evolution it might influence their timeline such that it could risk interfering with their past discovery of time travel or risk the technology ending up in the wrong hands in the future. Or maybe, just maybe, they are simply too "cool" to travel all that distance backwards in time (and spend who knows how much money to do so) just to have cheap chips and dip for an hour or two with a room full of MIT nerds? I mean hey, if I could travel backwards in time would I go to a geek gathering at MIT or would I go somewhere more fun (and with better food and drinks too) like an imperial party in ancient Rome?

In any case, the various potential risks of time travel might outweigh the potential benefit of any actual time travelers attending the MIT event. But let's hope that some real live time travelers do show up at the event. I know one thing for certain, if anyone does show up from the future they will probably be geeks too, since anyone who isn't a geek probably has other parties higher on their list.

Incidentally, this event reminds me of a similar proposal I came up with last year for building a receiver that might be able to receive a message from the future. While time travel by macroscopic things like people might be difficult or impossible due to the amount of energy required and the potential negative impact on the physical structure of the traveler, sending messages backwards in time could be more practical. Such messages could be comprised of subatomic particles or tiny black holes or local disturbances in fundamental fields or physical constants. The question is, how to design a receiver that could receive messages sent by beings in the future? If anyone can think of how to do this, blog about it and link to this article (since comments are off); I'll see your post via the trackbacks hopefully and if it's a really good idea I'll link to it from this article. If someone can design and actually build a suitable receiver then just like the MIT event, it could be publicized widely in the hopes that in the future if and when there is suitable technology, someone will send a message to it.

Links:

My friend, Tom Meyer, suggests that we might be able to utilize existing particle accelerators as "receivers" -- his idea is that we publicize that we will be analyzing the data from a particular device for anomalies placed there as messages to us. It's an intriquing proposal. Would it work?
