Use the web to find parking

There's lots of privately owned parking out there, even around airports, but nor market for it. What about a web market?

Imagine, if you owned a parking space, you could file it in a database. People going somewhere hard or expensive to park would go to the web before the trip, enter the address, and get offered a spot near their target with a rate. This could also include commercial lots with spare space. If not at the web, you could call from your registered cell phone for a small extra fee while driving to your destination.

PVR Video recording surfing

We all love our Tivo or other PVRs (though my mother just got the Scientific Atlanta 8000HD which does HDTV but otherwise has a terrible UI. It's hard to imagine this was designed after people saw the Tivo or Replay.)

After you use your PVR, you get a large library. Deliberately recorded programs, or in the case of the Tivo "suggestion" mode, programs recorded at random that are similar to shows you have asked to record.

Brave new world of Vasopressin gene therapy

Emory University scientists, taking one species of vole that is one of the extremely rare animals to be actually monogamous, found a gene to boost the effect of Vasopressin, one of the love hormones. Inserting this gene into other voles made them more socially monogamous.

I had heard of this before, and there has been science fiction about couples taking love drugs, but this story made me wonder about how people might try to alter the concept of marriage.

Solar powered, wireless webcam

Everybody loves their webcams (though the surveillance aspects of some are to be worried about.)

What about a way to make them cheap and easy to put in cool places. Combine a webcam with a solar panel, 802.11 link and small bettery. The webcam charges the battery off the panel, and when there is enough charge to take a picture, it takes one and spits it out the wireless link. You don't need much of a battery or much of a solar panel, because the amount of power simply controls how often it can take a picture.

Condo network for tech-nomads

Later I will blog my observations on an attempt to do a 2 week working trip to Toronto, but before I do let me throw out and idea to make technomadism easier.

A network of condos, of similar value (with some exceptions) in the most interesting cities of the world. The condos would be "standardized" to include the following:

Stirling Engine based hybrid car

I'm not the only one to have thought of this, but as yet no real work has been done. How about a hybrid car powered with a Stirling Engine? (Not spelled Sterling, btw.)

The Stirling is more efficient than the internal combustion or diesel engine, and it's also a lot quieter. Sounds great, but it's not good for cars because it can't rev up quickly and it takes about 5 minutes to get the engine hot enough to run well. We want our cars to start the minute we put the key in.

Gas futures at the gas pump?

Commodities traders buy gasoline futures all the time. Could they work at the gas pump? Imagine a big gas chain willing to sell you future gas today. You would buy a coupon, good for 15 galons of gas in August, the month you plan a big family trip in the minivan. You're afraid the high prices in the future might hurt the trip, you can be protected against them. The futures might even cost less than gas at the pump today due to widespread belief that supplies will open up. In times of heavy fear they would cost less.

Better UI for Wifi password setup

The new genertion of WiFi equipment supports WPA (WiFi Protected Access) a version of the IETF's EAP protocol, so that superior key authentication with different keys for each user and the keys are much harder to crack. In corporate networks, the keys can be fetched via RADIUS -- effectively allowing a single login password to provide all network access securely.

High quality videoconferencing restaurant

It's always dangerous to predict that soon we will all videoconference, but the technology really is getting better (See the Marconi ViPr, for example.) And bandwidth is getting cheaper. The Marconi system wants 8 megabits bidirectional -- the secret being not to do very fancy compression to instead push for really low latency and hi resolution -- but this is getting to be more affordable.

Changing the letters on phone keys

When SIP was designed for internet telephony, the feeling was to get rid of the phone number and replace it with IDs with the form of email addresses. E-mail addresses are of course easier to remember and read, though as a downside they tie your address to a domain, which is fine if it's yours, but silly if it's your service provider's.

Hand Iraq to Sheikh Hamad of Qatar

Of course the Iraqis have not enjoyed having an American Military Governor, but are they ready now for a U.S. pullout? Here's an alternative.

The most remarkable man I have read about in the Arab world is Sheikh Hamad, the Emir of Qatar. How about giving him temporary power with a later handoff date to an Iraqi parliament. There's not a lot of coverage about him on the Web, but consider the following.

His family has been an absolute monarchy for a century. In 1995, however, he deposed his father in a family-supported takeover to become the new young Emir.

Trains that decouple and recouple

I've often wondered why, when you have an electric train line that has a terminus as the main destination, you can't give everybody an express train.

To do this, imagine for the commute home, a 5 car train starts downtown. It leaves and expresses a few stops down the line. (A local car leaves after to handle the stops close to downtown.) When it gets to point one, with sufficient warnings and many safeguards, it decouples, and the rear car brakes to stop at the first of its stations.
