What if?   1 comment

This is a post from re:kuwait, which I could not help, but borrow.

What would happen if it costs 18KD to fill up your SUV? Would your life be ruined? I don’t think so. What will happen is that you will adjust your lifestyle to meet this new reality. You might reconsider buying a new SUV, and maybe get a car with better mileage. People might decide not to buy a car at all, and you’ll find that there’s less traffic on the street because people who can’t afford to drive are now willing to carpool and use public transportation. 18KD is a reasonable amount to pay because that’s the true price of the petrol.

What if you had to pay over 1000KD every year to pay for you electricity consumption? What would change? You would obviously think twice about leaving the air conditioning on all the time even when no one is home. You will think about how much a house consumes energy before buying it. You decide that maybe a small house with a bigger garden makes more sense than a three floor mansion. We might find that we don’t have blackouts anymore. The KOC will be able to sell more oil instead of burning it to make more electricity for Kuwait.

What if water cost you 50KD a month? Will you stand idly by as your driver sprays you car with a hose to clean it, when a sponge will do the same thing for a fraction of the water? Will you decide against a lawn and maybe plant more appropriate landscaping for the region?

If resources are priced according to their true value, without subsidies or manipulation, then human behavior will revert to a mode of living that is both efficient and ‘sustainable’. People will never change because of morality and the desire to feel ‘green’. That’s bullshit. The only way we can ever change is if it hurts us in our wallets if we don’t change. We’re not pricing in what’s called the negative externalities; the unpriced cost of traffic, pollution, blackouts and wasted finite resources.

This might seem politically impossible in Kuwait, but what if there was a way to make it work? What if all the savings and revenue generated was given back to Kuwaitis as a form of energy rebate? That way we can reward good behavior while we punish wasteful people by punching them with the invisible hand. We can have our cake and eat it too.

Well, wouldn’t we be all very conservative, if we had to pay the ‘true’ price of the products and services? Things which are given ‘almost free’ tend to be overconsumed, just for the fact that you are not paying ‘too much’ for it. We would not be ashamed to be called ‘misers’, had we been paying thru our noses for the ‘true value’ of the service.

Well, its no longer the ‘green’ factor, but has to be the ‘conscious’ factor, that should determine the consumption pattern of people.

The Straddling Bus   Leave a comment

34677070

A big concern on top of urban transportation planner’s mind is how to speed up the traffic: putting more buses on the road will jam the roads even worse and deteriorate the air; building more subway is costly and time consuming. Well, here is an cheaper, greener and fast alternative to lighten their mind up a bit: the straddling bus, first exhibited on the 13th Beijing International High-tech Expo in May this year. In the near future, the model is to be put into pilot use in Beijing’s Mentougou District .

Proposed by Shenzhen Hashi Future Parking Equipment Co., Ltd, the model looks like a subway or light-rail train bestriding the road. It is 4-4.5 m high with two levels: passengers board on the upper level while other vehicles lower than 2 m can go through under. Powered by electricity and solar energy, the bus can speed up to 60 km/h carrying 1200-1400 passengers at a time without blocking other vehicles’ way. Also it costs about 500 million yuan to build the bus and a 40-km-long path for it, only 10% of building equivalent subway. It is said that the bus can reduce traffic jams by 20-30%.

Here is the presentation by Song Youzhou, chairman of  Shenzhen Hashi Future Parking Equipment Co., Ltd.

“What you can see from the video is traffic jams, what you can hear is noise, and there is also invisible air pollution. At present, there are mainly 4 types of public transits in China: subway, light-rail train, BRT, and normal bus. They have advantages and disadvantages, for example, subway costs a lot and takes long time to build; BRT takes up road spaces and produces noises as well as pollution to the air. How to develop environmental-friendly public transportation? Straddling bus provides a solution. Let’s watch a demonstration.

The straddling bus combines the advantages of BRT, it is also a substitution for BRT and subway in the future. As you all know, the majority vehicle on the road is car, the shortest vehicle is also car. Normally our overpass is 4.5-5.5 m high. The highlight innovation of straddling bus is that it runs above car and under overpass. Its biggest strength is saving road spaces, efficient and high in capacity. It can reduce up to 25-30% traffic jams on main routes. Running at an average 40 km/h, it can take 1200 people at a time, which means 300 passengers per cart.

Another strength of straddling bus is its short construction life cycle: only 1 year to build 40 km. Whereas building 40-km subway will take 3 years at best. Also the straddling bus will not need the large parking lot that normal buses demand. It can park at its own stop without affecting the passage of cars. This is what the interior looks like: it has huge skylight that will eliminate passengers’ sense of depression when enter.

There are two parts in building the straddling bus. One is remodeling the road, the other is building station platforms. Two ways to remodel the road: we can go with laying rails on both sides of car lane, which save 30% energy; or we can paint two white lines on both sides and use auto-pilot technology in the bus, which will follow the lines and run stable.

There are also two ways in dealing with station platform. One is to load/unload through the sides; the other is using the built-in ladder so that passengers can go up and to the overpass through the ceiling door.

Straddling bus is completely powered by municipal electricity and solar energy system. In terms of electricity, the setting is called relay direct current electrification. The bus itself is electrical conductor, two rails built on top to allow the charging post to run along with the bus, the next charging post will be on the rails before the earlier one leaves, that is why we call it relay charging. It is new invention, not available yet in other places.

The set here is super capacitor, a device that can charge, discharge and store electricity quickly. The power it stores during the stop can support the bus till the next stop where another round of charging takes place, achieving zero toxic gas throughout the process.

About the ultrasonic waves put forth from the end of the bus, that is to keep those high cars or trucks away from entering the tunnel. Using laser ray to scan, cars get too close to the passage will activate the alarm on the bus end. Inside the bus, there are turning lights that indicate a the bus is intending to make a turn to warn the cars inside. Also radar scanning system is embedded on the walls to warn cars from getting too close to the bus wheels.

Nowadays many big cities have remodeled their traffic signaling system, to prioritize public buses, that is to say when a bus reaches a crossing, red light on the other side of the fork will turn on automatically to give buses the right of way. Our straddling bus can learn from this BRT method. The car can make the turn with the bus if that is the direction it wants to go too; if not, the red light will be on to stop the cars beneath while the bus take the turn.

The bus is 6 m in width and 4-4.5 m high. How will people get off the bus if an accident happens to such a huge bus? Here I introduce the most advanced escaping system in the world. In the case of fire or other emergencies, the escaping door will open automatically. I believe many of you have been on a plane. Planes are equipped with inflated ladder so people can slide down on it in emergency. I put the escaping concept into the straddling bus. It is the fastest way to escape.

The bus can save up to 860 ton of fuel per year, reducing 2,640 ton of carbon emission. Presently we have passed the first stage demonstration and will get through all of the technical invalidation by the end of August. Beijing’s Mentougou District is carrying out a eco-community project, it has already planned out 186 km for our straddling bus. Construction will begin at year end.

Thank you”.
