February 2016 is a bit out of date.  Waymo self driving cars take all the fun out of this history lesson.  

Today I turned in my proposal to the US Department of Energy that takes the idea of changing the mail sorter and make it bigger to a new level.  HEFF is my new promotion that automatically moves freight across the US Interstate system.  As it turns out most freight ton-miles are totally avoidable.  Coal is a huge amount of shipping tonnage.  Likewise crushed rock and gravel accounts for another large chunk of shipping ton-miles.  Problem is highways and roads account for half of cement production using that gravel.  So if we completely stop using coal to burn and we stop building massive highways to support all these trucks ruining the pavement then the total amount of freight drops quite a bit.  Trains and pipelines each move about the same volume of mass but semi-tractor trailers move the rest.  Those historical designs are poor for all measures like speed, agility, braking, hill climbing, air pollution emissions, death toll from crashes, cost of diesel and taxes associated.  

Hyper Efficient Flexfuel Freight (HEFF) is the WaterBeads vehicles and guideway used for granular freight.  Almost all ton-miles of US freight can be shoved into a smaller vehicle 5,000 pounds per load.  Guideway pushing freight can launch a vehicle every second making the math easy to do since there are 86,400 seconds in a day.  So every guideway segment can move 216,000 tons of freight or liquid per day.  It does all this powered only by the sun that shines on the guideway.  At highway speed of 75 miles per hour it is 21 times as efficient as a diesel semi-truck.  At 180 mph it is still multiples more efficient than a truck going 75 mph with the same total load.  

My biggest problem with government grants is they require matching funds.  We will see if my proposal is understood that it can remove 100% of air pollution due to freight trucks, trains, and pipelines moving loads that can be divided into 5,000 pound increments.  Looking at the data from the Internet, it seems like it could capture about 80% of truck freight.  It is not a jobs program so it will put a lot of diesel trucking out of business.  Automation is coming as a natural progression.  That part is going to be a bit difficult to redirect that labor force to new adventures.  The attrition rate of long haul truck drivers should take care of the reduction in force. if handled carefully.  There are big loads like moving bulldozers etc that will require old-school trucking.  The diesel that the nation will not be burning can be sold to the world market helping with our trade imbalance.  

Going to the dark side TriTrack can haul those refined sweet crude oil products to the ports for export.  There is a shortage of pipeline capacity to move LNG and crude from the oil field to the refinery.  HEFF could do that nasty job safer than buried pipelines that regularly leak into the groundwater.  My city, Georgetown, TX has been in the news lately as the gas company here has let a leak go for a long time and it has saturated the Earth in several square blocks.  There is a 1000+ church that cannot hold meetings as the gas leak area is roped off and hundreds of gas company employees are running around trying to unsaturate the dirt.  There are naturally occurring caverns in the area so it is possible there are voids in the Earth under this gas leak that could hold a lot of natural gas.  It has been a month so far and weeks still to go before all those businesses can get back to work.  If natural gas is liquefied and carried in guideway vehicles leaks would be limited to 5,000 pounds at a shot.  It would not go into the dirt and cause such a commotion in the community.

Jerry,

 

"February 2016 is a bit out of date."

 

For you (and those that have been into this subject for decades), yes, ancient history. But for me and perhaps a few others it was a teaching moment, posing even more the question of why PRT, let alone dual mode, has never had any success. I'm still looking for the answer(s).

As for  "Waymo (taking) all the fun out of (it)", as I see it, when it comes to the complete program, Waymo is only a part of an equation that without Alden's contribution, just leaves all the more riders stranded and fuming on a black road to nowhere. For me, that makes it Wayless.

Thanks for the update on your HUFF project. Good luck with it.

Dave

It's hard to find a silver lining, but with transit now being shunned, perhaps authorities will be more willing to look at options that move just individuals or small groups?

Thanks for posting this important point.  Public health has always been a problem for the aircraft industry.  Confined spaces with limited fresh air and no attempt at cleaning the air provided to air passengers, has always associated flying with having a cold or worse after each flight.  Now that this new unknown virus has created a world pandemic, it is more clear how big box transit has to deal with tiny virus biological things.  It is bad enough that diesel fumes are associated with big box transit  but now pathogens are of dire importance.  This virus is not going away anytime soon.  It is still spreading exponentially all over the Earth and just because one nation is wealthy enough to bring it down to a few edge cases the rest of the world will not be able to control it.  There are 7.76 billion people on the planet and this virus could potentially take it down to 7.67 billion before everyone on the planet has formed an immunity without a vaccine to break problem.  Of course this is age specific so us older folks will disproportionately die first.  

My son and immediate family are pretty sure they had it and they are getting over the symptoms.  He is in Silicon Valley where travel around the world and to China is more common.  At the time he was sick there were not enough test kits to use on every suspected case.  

The stats I found for disease on big box (commercial airplanes) is for each person with a cold, flue or TB another comes off the plane with that disease.  These are from the 11 people seated nearest the sick person.  So the cure for big box transit is to break the boxes up into sub boxes and treat the air as if it was a hospital room in a chemical warfare situation.  The air can be cleaned of these virus objects but it is not the silly paper face mask and windex that will destroy the virus it is a chemical mist of oxidizer to attack the virus and kill it chemically.  Mechanically filtering will not capture the diameter of these tiny things.  UV will do some good but big box transit has never even addressed the fecal matter in the upholstery much less destroying an airborne virus.  

Your article also mentions that big box loses money already so this pandemic just slightly raises the tax money lost.  

The cure is to keep your air and your upholstery only your germs and viruses.  That means your wrapper or pod needs to be yours and not shared.  The power unit battery mule can be shared since it does not touch the inside of the cabin in any way.  The vaccine seems to be about 1.5 years out thus far.  We just don't know.  What we do know is people really like to buy toilet paper in a pandemic.

I think the private car version of RUF is great for keeping virus and germs from spreading human to human.  The big box version trying to say air flow can keep virus contained is not going to work.  Virus size is too small and floats in the air.  Air turbulence will not keep the virus in a straight line as shown.  They will be going everywhere at roughly 30 mph. (diffusion) If you pass gas in a room the smell moves at about 30 mph across the room.  The size of these creatures is so small they will move with the air as fast as smell.  Blowing air across people will just make transfer worse.  Isolation is best even though it too is a numbers game.  This virus is a striking example of how connected the entire human race is.  Spreading the virus is only a way to let the needed hospital equipment catch up to coming predicted demand.  The cure is a vaccine.  The nations of the world have shown they are powerless against this tiny virus.  The actions we know to do, we did too late.  It only takes a few uncaring vectors to spread any disease to everyone.  

I think this discussion is important and not just for this one virus.  My wife runs the laboratory for the local pediatrician group.  Their flow of sick children is markedly down from normal.  Social distancing not only slows the growth of this one virus but it has slowed down the normal childhood disease transmission.

I think you misunderstand the Construction.

There is a screen between each seat compartment, so the air is forced to go from top to Bottom and cannot enter the other seats.

 

I may not have described it clearly enough, so thank you for giving me this feedback :-)

Looking at a small scale PRT system it would be pretty easy to add in a mister system for sanitizer to kill any germs left from respiratory droplets after the end of each rush hour and as needed otherwise at the storage locations. It could be something as simple as an arm that zooms into the vehicle, gives a quick spray, and then pulls out for next one. Time is likely in the 30 seconds per vehicle range. Let's assume it's doing some 5-7 trips per rush hour and occupancy of 1.4 gives us some 7 to 10 people in between sanitizing with only the last ones at slightly higher risk. The dirty cars or those with trash would go through a normal cleaning/wash cycle with the same results. I don't see this solution as being very invasive or expensive to set up.

On topic:  Dave Petrie's car (pod) transporter is, and always was, well suited to the needs of global transport.  As you know, I have adapted it to run at high speed on Bladerunner transporters along an electric highway/rail corridor.  It is also intended to charge the microcars (freight pods) enroute etc...

Off topic: Please find attached a couple of sketches of a clockwork ventilator I am working on.  It is designed to simply run off bottled oxygen with the O2 exhaust feeding into the supply for the mask.  I'll let you know how the build goes this week and then the plan is to test it, simplifiy it further for quick manufacture and build a batch.  I a few weeks we aim to send off working versions to engineers around the world along with animations, drawings and instructions so that it can be replicated in larger numbers locally.

Be careful with pure oxygen.  It can surprise you if you have the wrong materials.  How are you planning to let the user know when to change the oxygen tank?

Hi Jerry,

Thanks for your feedback.  The oxygen only contacts the feed lines the silicone tubing and BVM.

The nurse will log cylinder pressure on his/her rounds and schedule a replacement (+spare).

I would not want to bet my life on a nurse coming by on a regular basis.  I have been in too many hospital rooms looking after family members to believe that nurses will come in time.  My brother died from his ventilator tube coming out so this one is close to me.  I would suggest having some kind of redundancy on keeping this thing going.  My brother's ventilator had a loud alarm that went off many hours before the backup battery ran out or it sensed a failure. 

I have always thought that the hospital equipment should be mounted to the patient and not screwed to the wall behind them with a zillion wires all in the way.  I can visualize a chest piece with open front that contains all the heart monitor wires.  Two leg compression tubes that are self-contained that quickly unbuckle instead of velcro and a blood oxygen level that does not go on your index finger.  There is so much wrong with hospital equipment but the clinical trials have always kept medical equipment crazy expensive while being at least 15 years back in technology.  I know because I did heart pacemakers a long time ago and they have not evolved hardly at all even though the digital world has leapt forward tremendously since then.  You may be the design company to put out this chest plate hospital room in a cast fiberglass part.  There should be no reason for a wire or a tube to be loose around a sick person. They flail and spin in the bed which is a good thing.  Holding them still with a random assortment of ligatures just makes the experience miserable.  In addition to heart monitoring, oxygen level and a port to introduce liquid medicine directly into your bloodstream, someone someday should create a mechanical device that detects pee and removes if from the patient without causing so much pain and commotion.  Again anything medical is totally out of the realm of a start up but in these strained times there may be a window where ideas can be crowd created that can slip past the gatekeepers slowing down new products into the medical field.  So your task -- (like the way I am bossing you around?  ;-)   ) Design three pieces of battery powered equipment that are also stylish and go with each other.  1. Design a heart monitor with wire set that covers the wiring to the patient so that a flailing semi conscious person can never pull on a probe wire inside the shell and output the results wirelessly to the nurse's wrist watch.  2. design a pair of quick-opening tubes that compress the legs to avoid blood clots in bedridden patients.  3. Design a pee remover and a similar but more elaborate poo remover that avoids having to get up out of bed and do the thing while keeping the area jet washed clean and then fully dried.  

When you get those three three designs done and in a comforting gender specific style, I want you to solve world hunger.  ;-)    

I have great respect for your skills.

Hi Everybody,

I need some help with a patent search in the RUF/Tritrack/Bladerunner space, and would like to set up a zoom with interested parties. For passenger and light freight, this now strikes me as obvious and inevitable.

Best,

Bruce

Here is what I sent to your federal government about HEFF (Hyper-Efficient Flexfuel Freight).  Let me know when you want to make the call.  

The concept of a rolling virtual distribution network combining and dividing freight items is contained in this.  Factory conveyor to end customer at 180 mph would revolutionize mail and FedEx et al.
