As with the three other longest and heaviest floating bridges on the planet, the colorfully named SR Bridge makes its home in the Seattle area. More News Summary Good design and advanced materials can improve transportation and energy, water, and waste systems, and also create more sustainable urban environments.
Posted 6 years and 1 month ago Monalisa mohanty from India comments on What infrastructure challenges face your community? I find input provided by you very useful in my development work, Kindly suggest any possible bio low cost water, sanitation, swerage options also water harvesting alternative for storage purposes in dry areas guidelines if any to make it available to poorest of poor communities.
How to create a sustainable infrastructure mechanism for a community of say families Darrlynn Franklin Posted 7 years ago Darrlynn Franklin from MidAtlanticBroadband comments on What infrastructure challenges face your community?
I would like the opportunity to read the infrastructure challenges communities in America are facing. I would also like to know your recommendations on how to fix the challenges these communities face. The ideas and assertions made are appreciated.
Just a quick read supports the sincerity and professionalism of the writers. However, we have learned that sincere, well-intentioned professionals can be dead-nuts wrong.
It appears that most wish to repair or replace what exists with still more types of physical solutions. This suggests that perhaps we are not discerning the root cause of how we have planned, engineered, and constructed our physical world into its current state.
Its less a matter of discovering new ideas than it is learning to see familiar circumstances with a new clarity. Of course, I may be wrong. Thanks for considering my thoughts. Posted 9 years and 1 month ago David O.
Now is the time to provide incentives to employers to discount homes for workers near where they work. This will cut down on commute, traffic, pollution, accidents, travel time.
Maximize workforce hours, family time. Do this now while economy is down and everyone has to move anyway. Less commuting may even mean families won't need a second or third car.
We need to develop incentives to dismantle large cities. Sustainable, smaller communities, built to allow walking to work, shopping and schools are needed. Link these smaller communities by rail, the most efficient form of transportation. Dismantle suburbs, end long commutes and eliminate urban centers.
Once we reduce cities to sustainable communities, we will need less hydrocarbon fuels, use fewer resources and have less adverse impacts on the earth. This is not an engineering problem.
This is an institutional problem. The infrastructure problem in the US is that public infrastructure providers do not recover costs, do not send the right price signals to end users and do not fund depreciation of fixed assets.
We cannot engineer our way out of the problem until we fix the institutional problems that are the root cause.
Evacuated Tube Transport ETT tm A patented technology where travel occurs without air friction or rolling resistance like "Space Travel on Earth" tm ; ETT can accomplish 50 times more transportation per kWh than electric cars or trains. ETT is silent, a fourth the cost of freeways, safe, faster than jets, and is electric.
Air is permanently removed from 2 tubes along a travel route two-way. Pressurized car sized passenger capsules travel in the tubes on frictionless maglev. Airlocks at stations allow transfer without admitting air.
Linear electric motors accelerate the capsules, then they coast through the vacuum most of the trip using no power. Energy is recovered when they stop. Speed in initial ETT systems is mph for in state trips, and will be developed to 4, mph for international travel that will take you from NYC to Beijing in 2 hours at a tenth the cost of airfare.
ETT is networked as are freeways. ETT capsules hauling up to 6 people or 3 pallets of cargo are automatically routed non-stop between "off-line" stations that are disbursed according to demand, so ETT has potential to eventually serve homes.With a report card like this, today’s engineers face the challenge of restoring and improving infrastructure to support civilization, especially in high-density urban areas where the daily stress of many residents wears on buildings, roads, and other structures.
Restore and Improve Urban Infrastructure.
Why is it a current problem? What do we know about the topic as of today?
discuss what future engineers will need to do to combat this issue. What new technologies or tools do we need? Who will be needed (what professions)? Are . Restoring and Improving Urban Infrastructure By: Connor Asfour Final Idea The major grand challenge for infrastructure engineering will be not only to devise new approaches and methods, but to communicate their value and worthiness to society at large.
design by Dóri Sirály for Prezi. Good design and advanced materials can improve transportation and energy, water, and waste systems, and also create more sustainable urban environments.
In , the American Society of Civil Engineers issued a report card, grading various categories of U.S. infrastructure. Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book.
Restoring and Improving Urban Infrastructure According to the National Academy of Engineering, infrastructure is the combination of fundamental systems and structures that support a community, region, or country.
