Many are commenting on the gasoline shortages and price increases involved with hurricane evacuation and other emergencies. Some people can't get gas to get out of the city. Others full up giant tanks even when they don't need it. Stations raise prices as supply drops and demand increases, as per the normal rules of the market. Some suggest the stations be price-controlled to stop this, but that would only result in even more gas hoarding by the public.
Every time I take an RV trip (ie. each Burning Man) I come up with more observations. The biggest one is that it cost $360 in gasoline to go from the bay area to the black rock desert, about 800 miles. And that's at a price still well below world price. The RV owner said he was planning to get out of the business, people no longer want to pay the gas price.
I recently picked up a surplus battery-powered motor assist for a bicycle, and it's a lot of fun. Due to lower power you have to start peddling to 3mph and then it can run the bike for 10 miles at 10mph (for normal weight people, not me.)
Mapping programs, and fancy GPSs come with map databases that will, among other things, plot routes for you and estimate the time to travel them. That's great, but they are often wrong in a number of ways. Sometimes the streets are wrong (missing, really just a trail, etc.) and they just do a rough estimation of travel time.
Ok, this idea will make no sense to those who have not gone RV camping. RVs have 3 water tanks -- one for fresh water, one for the toilet sewage (known as "black water") and one for the other drains (shower, sinks) known as "grey water." When you camp in unserviced campsites for a while you become very aware of the capacities of your tanks.
However, the RV uses the fresh water tank to "flush" the toilet. It seems to me that with a small extra water pump, one could use the grey water, or a mixture -- grey with a final spurt of fresh to rinse the bowl.
RVs don't really flush the toilet, that would use way too much water. You rinse the bowl after #1 and you pre-fill the bowl before #2 and rinse later.
Having completed a long fly-n-drive road trip, I have some lessons and observations.
If you will be driving a lot, use a rental car even if leaving your own city. We put 3000 miles on our rental car for $300 -- far less than the depreciation cost would have been on my own car.
It's great to have a cooler in the car, you can buy perishables and get cold drinks when you want them, but forget about those $5 styrofoam coolers for any long trip. Within a few days ours was leaking, we fixed it by putting a plastic bag inside and out, but they are not very sturdy. There are collapsible coolers and we have one but didn't have luggage room. You can buy a cheap solid cooler for under $20 at wal-mart or Costco, but it seems wasteful to throw it away. If you have extra luggage, you can fill a cooler with stuff, duct tape it and check it as luggage, however.
Perhaps this is one of those ideas that some car has implemented and I haven't yet seen it. As many people know, in several years ago a number of cars arranged so that their interior lights would not go off immediately when you closed up the car. This gives you the ability to still see shortly after closing up the car and walking away.
Of course this also drives people nuts, because in many cases you can't tell if the lights stayed on because you didn't close a door properly, and you would end up waiting around to see if they would go off.
RVs come in all sizes, from 40' bus to towable pop-up. But what about inflatable in a trunk in the back of a minivan?
Setting up and tearing down tented campsites is a pain, and there are instant-setup tents and even some inflatable tents. But what about a super-duper inflatable tent, designed for car-camping.
Ok, I'll admit this is a crazy idea, not likely to ever see the light of day, but it's worth throwing out as an exercise. It is often said we should keep the speed limit low to encourage good fuel economy.
What if there were no speed limit, but instead a "fuel limit." For example, 2 gallons of gas per hour.
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.
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.
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.
Carpool lanes exist to reward those who work to reduce congestion and pollution with a faster trip. I know that's good every time I look out my window and can't see the hills for the haze. Some areas allow zero-emission-vehicles (electric cars etc.) to also use carpool lanes with a solo driver, reducing pollution if not congestion.
Proposals have been made to also allow solo drivers of hybrid cars into the lanes, as well as solo drivers who simply pay a fat fee for a permit. Let me propose an interesting variant of these payment ideas.
Pardon the local entry boring to those outside this valley.
San Jose is seeking something "distinctive" for the airport remodel. Let me suggest something I have not seen anywhere else, something that would say something about the area.
Reading this NYT article about radar to cover car blind spots, which describes a system that will trigger lights in the rearview-mirror when cars are in the blind-spot, reminded me of an old idea I had some time ago I called "Eyes in the back of your head."
The idea would be to wear a special collar while driving. This collar would contain small electrodes that could lightly stimulate the skin on the back of the neck. Perhaps just one row, but ideally a small 2-D image should be possible.
This would be connected to a camera, radar or sonar system pointing back from the vehicle. It would map where other vehicles are, and turn that into an image on the back of the neck.
Thus, as a car came up behind you and passed you, it would feel like something brushing the back of your neck on one side.
I was inspired to this by reading about a system for the blind that mapped a video camera image onto a 2000 pixel electrode map on the stomach. It was found that over time, the nerves would retrain and a sort of limited vision could develop. Might this have application in driving, or perhaps combat?
Another transportion item, because last night the train I was on hit a car stalled on the tracks (the occupant is OK, though was hit by the car when the train bashed it.)
Since trains do hit things, why aren't solutions to this more common in our data network world? A laser detector over the grade crossings would be simple enough.
I'm going to write more in the future about how transportation is not making using technology. Let me start with streetcars and the bus.
People use transit a lot more if it is able to beat the car, or at least keep pace with it. Thus we spend a lot of money on dedicated right-of-way for subways, trains and streetcars.
But this is really inefficient. The dedicated right-of-way sits empty 95% of the time. It does nothing so that a train can pass over it every 10 minutes (or more.)
