Kinetica
Sewn invisibly into the lining of normal clothes, Kinetica generates energy as you walk and move around, and uses it to charge up your personal electronic devices - mobile, music player or laptop. Very thin zinc oxide wires are sewn into normal clothing, down the seams of trousers or in coat and jacket sleeves. Every time the wearer moves, the wires move too, and the flexing and relaxing of the wires produces an electric current. If the electricity that Kinetica collects isn't used by personal systems, it can be discharged to the power storage systems of a home or car, or can be directed to the devices of friends or family instead.
Energy Producing Roads
Energy Producing Roads made from solar cells and glass may be the solution to carbon emissions and climate change.
Background
Although Scott Brusaw's company, Solar Roadways, is based out of his house in Idaho and in the home electronics workshop he built next to it with the income from his consulting, it may hold the key to solving climate change and global warming.
Background
Although Scott Brusaw's company, Solar Roadways, is based out of his house in Idaho and in the home electronics workshop he built next to it with the income from his consulting, it may hold the key to solving climate change and global warming.
Solar Roadways is still in the concept phase, built on Brusaw’s childhood fascination with an electric race car game called slot cars. The idea of cars running on electric roads stayed with him as he went on to earn his Master's degree in electrical engineering. As global warming became established science, his wife Julie suggested he turn his obsession with electric roads into a way to conserve fuel and reduce pollution. Brusaw came up with the idea of a road that produced its own electricity, a solar highway for energy independence.
One of the nation's leading authorities on solar energy, Nate Lewis of Caltech, has calculated that covering 1.7% of the land surface of the United States with 10 percent efficient solar energy converters could supply all our current national energy demand. As it happens, this is roughly the same amount of land that is devoted to the nation's interstate highway system. Lewis believes that covering a large, barren section of some of the western states with solar panels is the best solution to our energy needs, but we would need a photovoltaic material almost as cheap as paint to make it cost competitive with fossil fuels, and we would still need to transport the energy around the country.
In Brusaw's Solar Roadways concept, instead of covering a large area of the Southwest with solar arrays, all of our roads would be paved with glass panels that could collect and distribute solar energy. Sunlight would shine through the surface onto a middle layer of solar cells. The solar cells would produce electric energy to light the road at night and heat it in winter, with enough leftover electricity to power homes and businesses. Brusaw estimates that each mile of solar panels could power 500 homes.
Brusaw's Rationale for Solar Roadways includes:
· 4.84 billion (12' by 12') Solar Road Panels would be required to replace the current asphalt road system, parking lots, and driveways in the 48 contiguous states. This is enough to provide three times more electricity than the United States used in 2003 and almost enough to supply the entire world.
· To produce a Solar Roadway Panel (not including assembly and installation) would cost approximately $5,000 for materials. Solar cell cost and efficiency is predicted to improve dramatically with thin film technologies in the next few years.
· Cost to build enough coal-fired power plants to provide a similar amount of electricity - approx. $14 trillion.
· The cost of Global Warming is unknown, but could reach 5% to 20% of global gross domestic product annually, according to the Stern Review on the Economics of Climate Change.
To answer the energy transport needs, the roadway's base layer would contain the nation's electric grid, safe from weather and secure from interruption, replacing the current crumbling power grid with a distributed network of independent power sources providing energy from coast to coast. Along with electricity, the base layer could also carry fiber optic cables for television, communication, and high speed Internet so that cities and rural areas would be equally connected and the ugly poles and wires that clutter our landscape could be removed. Smart roadways could reconfigure travel lanes to reduce gridlock, warn drivers of construction or obstacles ahead, sense whiteouts or other weather conditions, and even keep wildlife off the roads. In Brusaw's scheme, heated and lighted roadways would make travelling safer and save lives.
Most of the technologies required for the base and middle layers are already available, Brusaw told the glass scientists and industry reps at a Washington workshop. With only a minute of his allotted time remaining, he summarized his challenges to the scientists and manufacturers: Build a transparent glass panel that absorbs sunlight without any glare, lit by low energy LEDs from within, with heating elements to melt ice and snow and a surface both fireproof and shatterproof with traction equal to asphalt, even when wet, with the ability to withstand road salt, magnesium chloride, sun exposure, vehicle emissions such as antifreeze and oil, and the strength and flexibility to handle heavy trucks. And finally, in order to make the project economically feasible, the glass should last about three times as long as most asphalt roads, he concluded.
Creating solar roadways may be possible with some new enabling technologies. These new technologies include new types of self-cleaning windows with microstructures based on the lotus flower's ability to shed water, and recent breakthroughs in superconducting transmission cables cooled by liquid nitrogen that carried five times the current of standard cables.

A sustainable city-region for Bristol
Jonathon Porritt will talk about the challenges we face in making cities more sustainable before outlining the programme’s short and longer term plans for the Bristol city region.Having immersed myself in Bristol life for the past six months, and met with a huge variety of organisations concerned about the city’s future sustainability, it’s clear that our task in Bristol is considerable. But with so much energy, enthusiasm and commitment from all parts of the community, if we can create a sustainable city anywhere, it surely has to be Bristol. The City was ranked third in Forum’s Sustainable Cities Index. Yet there are still big issues to sort out, not least with transport and new housing numbers – 90,000 new homes are planned for the area. Tackling these issues, in partnership with others, will be a big focus of our work. Managing the need and demand for travel through the use of IT, and the promotion of active travel and public transport will be early areas of work in supporting sustainable transport. In relation to new homes, we’ll be using our Sustainability Framework for Urban Extensions to ensure that new communities are planned, designed and built to the highest sustainability standards – if they can do it in China, it’s about time we started doing it here too.These are exciting times for anyone living, working or shopping in the Bristol area, and I look forward to hearing from you over the coming months.

New town of Northstowe
Review date: 05 March 2008Lead designer: Arup Associates
Local authority: South Cambridgeshire District Council
Region: East of England
Description: A new town comprising up to 10,000 new dwellings and associated community and highway infrastructure.
Summary
We welcome the rigour of the approach the design team have taken; the masterplan is of high quality and has potential to be a successful new town. The introduction of 9,500 new homes in the south of Cambridgeshire is a challenge that requires a clear vision as well as careful analysis and understanding of the surrounding landscape and places. We feel that there are still aspects of the masterplan that should be addressed.
At the moment we are concerned that design development of the masterplan has not fully resolved issues of identity, morphology and connectivity. We think there is further work needed by all the parties involved in this project and encourage the design team with the local authority, English Partnerships and the developer to continue working together to resolve these issues. The local planning authority has concerns regarding identity, phasing and sustainability; we agree with their views and these are discussed in more detail below.

Understanding Ordinary Landscapes
(1 anmeldelse):
Understanding Ordinary Landscapes by Paul Groth is a collection of contemporary cultural landscape essays and is a theoretical basis for comprehending the mysteries of perception of the landscape, the environment, and furthering the culture versus nature discourse. It brings critical analysis, and an annotated bibliography to the relatively new area of landscape architectural theory. A must for professionals and anyone interested in the landscape.
Sustainable Urbanism: Urban Design With Nature
(1 anmeldelse):
Chicago City Planning Consultant Doug Farr has written a great book, Sustainable Urbanism: Urban Design with Nature. Farr combines new urbanism with green development in a clear and logical manner. He believes that "sustainable urbanism" is more than designing new Leed certified green buildings. It also includes the creation of green sustainable neighborhoods, and includes plans for sustainable urban development. He combines the strategies and principles of new urbanism with environmental improvements very well. Farr explains the evolution of the design reform movement. He outlines strategies on how to lead and promote sustainable urbanism. Doug Farr did an outstanding on form based codes for our neighboring communities of Bloomington and Normal, Illinois, and in developing plans that enhanced the environment while creating new urban space. I strongly recommend this book.

IBM Launches PowerUp - Online Climate Change Game
A new IBM promotion comes in the form of a free multiplayer online game, PowerUp, that challenges players to help save the planet “Helios” from ecological disaster.
The game is part of IBM’s TryScience initiative and was launched at Engineer’s Week 2008. The game features a planet in near ecological ruin where three exciting missions for solar, wind and water power must be solved before sandstorms, floods or SmogGobs thwart the rescue. IBM says that it devised the 3D virtual game to engage kids and educators in engineering, energy, and diversity awareness.

Living machines
Living Machines are a form of biological wastewater treatment designed to mimic the cleansing functions of wetlands. They are intensive bioremediation systems that can also produce beneficial by-products such as methane gas, edible and ornamental plants, and fish. Aquatic and wetland plants, bacteria, algae, protozoa, plankton, snails, clams, fish and other organisms are used in the system to provide specific cleansing or trophic functions.
By the year 2025, 35% of the world’s projected population will live in countries facing water shortages.
ACTION ON SOLUTIONS
An ecosystem approach: Natural ecosystems have intricate and resilient mechanisms that filter and replenish freshwater resources and sustain marine environments. Although human technologies may enhance or replicate these mechanisms in some settings, protection of the natural watershed also is critical. An ‘ecosystem approach’ recognizes and ascribes value, including economic value, to the ‘services’ natural ecosystems provide in terms of water filtration and purification, and ensures their sustainability, through modern management regimes.

Concentrating solar
Getting a Hot Shower
Most home solar power is generated through standard photovoltaic technology, which uses large panels to convert sunlight at varying efficiency into electricity. But a new way to harness the sun has emerged. "Concentrating solar" focuses light onto a liquid-filled pipe, which produces steam that powers a turbine as it heats -- the same way you burned ants with a magnifying glass when you were a kid. Companies like Ausra and Abengoa are trying to commercialize the technology at the megawatt scale, but Heliotron, a small Greek company, is offering a type of concentrating solar for home use that it claims can generate 420 watts of power and 210 liters of hot water, too.

Eco - materials
Like a Live-In Lego House
The old model for making a home is to dump a bunch of wood and drywall at a job site and assemble the house in situ. But a growing number of builders, like Parco Homes and Michelle Kaufman, want to revamp that process and create Lego-like homes that can be snapped together. The modular designs are more efficient and consistent. Parco features a broad range of eco-materials, like the superinsulating window sample shown here, which features a transparent jelly between the two panes of glass to reduce heat loss.

Efficient lighting
LED Lighting the Way Home
Light-emitting diodes, or LEDs, are remarkably long-lasting and efficient lighting, but most of them are small and located in everyday products like remote controls. GlobalGreen wants to change that with its street-light replacement LEDs. Using a mere 50 watts of power (about a 60 percent reduction), this light is very bright (3500 lumens) and will last for 60,000 hours before needing replacement, the company claims.

BYGGEMATERIALER/BUILDING MATERIALS
Det rigtige valg af materialer er en essentiel del af processen mod den bæredygtig by. Bæredygtige byggematerialer har før i tiden været forbundet med større omkostninger end traditionelle byggematerialer, men dette billede er under forandring.Man ligger mere og mere vægt på materialernes levetid og omkostningerne ved at producere og skaffe sig af med materialet efter endt brug. I udviklingen af de bæredygtige materialer er det æstiske begyndt at blive en designfaktor, efter en periode med test af mere grove byggematerialer. Så det er muligt at designe bæredygtig arkitektur og byer og som samtidigt tilfredsstille et æstetisk ønske.

COMMUNITYMARKET
Indkøb er en del af vores daglige gøremål og kan derfor danne ramme om den uformelle meningsudveksling i det lokale supermarked. Ved kommunernes sammenlægning blev der nedlagt og flyttet flere rådhuse, der indtil da fungerede som lokalsamfundendes fora. Man kan forestille sig det multikulturelle og lokale marked i en udvidet rolle kunne understøtte freecycling, fælleskørsel, grønttorv og evt. indgå i hybride sammenstillinger med boliger, erhverv, daginstitutioner og lign.
TRANSPORT
Selvom personbilen på mange måder ønskes erstattet med kollektiv trafik vil den stadig være en del af fremtidens bybillede. Derfor vil der være behov for veje og parkeringsmuligheder i forskelligt omfang.
Hvordan begrænses omfanget af den synlige tilstedeværelse af disse elementer?
- Eller omvendt hvordan kan tilstedeværelsen betragtes som en kvalitet og lade veje og parkering indgå i sammenhænge, som understøtter bæredygtighed og byens identitet?

BYØKOLOGI/URBAN ECOLOGY
Selvom byen som socialt, økonomisk og økologisk fænomen er den mest bæredygtige livsform, er den samtidig CO2 forureningens største synder. Verdens storbyer står for størstedelen af den samlede udledning. Byøkologi fokuserer på helhedsorienterede løsninger på problemstillinger, som vedrører et givet områdes ressourceforbrug, miljøbelastning og naturindhold. Denne indsats inkluderer den måde vi bygger og bor på, vores adfærd i håndteringen af ressourcer og vores daglige forbrug.
Kan vi løse alle problemer ét sted i stedet for at prøve at løse ét problem alle steder?
Kan ideer som urban farming, freecycling o.l. udvikles til holdbare og bredt accepterede løsninger?
Hvordan kan økologiske tiltag fremmes uden at det opfattes som pligt og afsavn?
Hvordan kan vi optimere udnyttelsesgraden af ressourcerne i byer og bygninger?

TÆTTERE OG GRØNNERE/DENSER AND GREENER
Byer over hele jorden vokser hastigere end nogensinde. Netop i år regner man med at bybefolkningen vil overstige landbefolkningen i antal, og tendensen fortsætter. Denne urbanisering foregår ved forskellige hastigheder, men billedet er generelt, og også i Danmark flytter befolkningen fra landet til byen. Den kraftigste tilvækst sker i de større byer og prognoser viser at Århus inden for de næste 25 år vil vokse med op mod 75.000 indbyggere.Bosætningstendenserne viser at mange gerne vil bo i og omkring de større byer. I Århus har boligpriserne inden for ringgaderne nået et niveau som ligger over mange menneskers økonomiske formåen. Mange af dem som gerne vil bo i byen har ikke råd til det. Studerende, nyuddannede akademikere, iværksættere osv., er grupper der traditionelt har bidraget til "det gode byliv", som forbrugere af de mange tilbud der findes i de større byer. Mange bevæger sig derfor langt for at benytte sig af kulturtilbud, indkøbsmuligheder og tage del i bylivet. Resultatet er bl.a. en enorm trafikbelastning med store konsekvenser for miljøet og et konstant behov for udbygning af infrastrukturen.
Århus Kommunes byvækststrategi opererer med to hovedprincipper: Byudvikling som dækker fortætning og by-omdannelse i eksisterende byområder og Byvækst som dækker inddragelse af nye arealer. Langt den største udvikling kommer til at foregå på nye arealer i byens periferi, som udbygning af de eksisterende forstæder, og der vil blive behov for op mod 50.000 boliger i løbet af de næste 25 år.
Selvom mange gerne vil bo i byen opfylder det traditionelle parcelhuskvarter stadig boligdrømmen for mange mennesker. Men efterspørgslen og et stadigt stigende arealbehov truer med at underminere de kvaliteter parcelhuskvarteret kan tilbyde. Fællesskab med ligesindede, tryghed, den friske luft og nærheden til det grønne må tilbydes i nye rammer.
Byliv, bosætning og natur er de grundlæggende elementer, som må bringes sammen i Fremtidens Forstad. Vi må gentænke forstaden og planlægge med bæredygtighed, som en grundlæggende forudsætning! I Fremtidens Forstad skal vi derfor bo både tættere og grønnere.
BÆREDYGTIGHED/SUSTAINABILITY
Bæredygtig udvikling handler om at skabe betingelser for det gode liv. For at opnå bæredygtighed skal der skabes balance i samfundet; en balance der skal ses som summen af både miljømæssige, sociale, økonomiske og kulturelle forhold. Fremtidens byer må planlægges så de fordrer denne balance og indeholder den dynamik, der er nødvendig for at sikre kvalitet i udbygningen.Men hvilke konkrete udfordringer står vi overfor når vi skal planlægge Fremtidens Forstad?
Og hvordan kan vi gøre disse udfordringer til operative redskaber i arbejdet med at skabe den bæredygtige by?
COMMUNITY BUILDING
Hvis vi skal trives i en by, er det vigtigt, at vores lokalsamfund har en overskuelig størrelse. Det er i nærmiljøerne at hverdagslivet udspiller sig, både hvor vi bor, hvor vi arbejder og hvor det kulturelle liv udspiller sig. Hvis vi skal føle tilknytning til et sted, må det kunne imødekomme forskellige gruppers livsstile og behov. Men det er ikke nok at skabe funktionelle boliger og gode indkøbsmuligheder. Summen af lokalsamfundets elementer skal være en meningsfuld og identitetsbærende ramme om hverdagslivet. En ramme som virker befordrende for sociale netværk og understøtter en kvartersdannelse.
Hvordan skaber vi både balance og diversitet i et byområde, og hvordan sikrer vi kontinuitet i den givne beboersammensætning?
Hvordan skabes de bedste betingelser for udviklingen af et lokalsamfunds selvforståelse?

Hvordan skabes de bedste betingelser for udviklingen af et lokalsamfunds selvforståelse?
MOBILITET/MOBILITY
Privatbilismen er en forudsætning for de forstæder vi kender i dag, men den stadig stigende bilisme er også en af de største syndere i miljøbelastningen, og den motoriserede livsstil påvirker folkesundheden. Fremtidens Forstad må udvikles så den tilgodeser den kollektive transport og virker befordrende for den lette trafik. POD (Pedestrian Oriented Development) er en værdibaseret tilgang til byplanlægning, som fokuserer på livsstil og miljø. Målet er at motivere fodgængertrafik og tilgodese de lette trafikanter. Dels som et redsskab til at skabe levende og sunde byer, dels for at motivere legemlig bevægelse frem for bilisme. Fremtidens Forstad må have en størrelse og en struktur som gør bilen overflødig.Hvordan skaber vi øget fokus på de lette trafikanter i udviklingen af vores byer – ikke blot i den konkrete byplanlægning, men også i befolkningens bevidsthed?
Hvordan skaber vi en by, der motiverer brugen af kollektiv trafik, prioriterer de lette trafikanter og ideelt set gør bilen overflødig?
Hvordan kan privatbilismen reduceres uden at vores mobilitet hæmmes?
DE ÆNDREDE FAMILIEMØNSTRE/CHANGE OF FAMILY PATTERNS
Den traditionelle kernefamilie har fået konkurrence af helt nye kategorier, som har deres egne krav og ønsker, til hvilke rammer livet skal leves i. Singles, DINKs (Double Income No Kids) og pendlere bruger alle hjemmet og byen på vidt forskellige måder og de ændrede familiemønstre stiller nye krav til vores byer og boliger. Hvis man vil imødekomme den stigende diversitet i befolkningens livsførelse må man planlægge efter den. En mangfoldig beboersammensætning kan ligeledes være med til at sikre den sociale og kulturelle bæredygtighed.Vi ændrer behov flere gange i livet og den ene livsstilssituation afløser den anden. Hvordan kan vi skabe boliger der løbende tilpasser sig vores behov?
Hvordan kan ung og gammel få udbytte af at bo dør om dør, og hvilke faciliteter kræver det?
(FRI)VÆRDI?/EQUITY VS. EQUALITY?
Der vil i fremtiden blive behov for et stort antal boliger, der er økonomisk tilgængelige, i og omkring de større byer. Der er i dag samfundsgrupper, hvis økonomiske formåen gør dem ude af stand til at bosætte sig i de store byer, hvor deres kompetencer og tilstedeværelse ellers er efterspurgt. Nyuddannede akademikere, studerende og iværksættere er en vigtig ressource for den konkurrencedygtige by, men netop disse grupper er som typiske førstegangskøbere, uden friværdi, udelukket fra boligmarkedet i de større byer. I Fremtidens Forstad må der skabes billige boliger i attraktive miljøer med gode transportmuligheder til erhvervsområder og uddannelsesinstitutioner.Hvordan kan grønne boligformer gøres ligeværdige og i sidste ende mere rentable end de traditionelle?
Kan boliglån være grønnne?
Kan vi skabe boligformer, der gør ejerskab muligt for alle samfundsgrupper og skaber en mere mangfoldig sammensætning i boligområderne?
VEDVARENDE ENERGI/RENEWABLE ENERGY
Vi bruger mere og mere energi, og den måde vi indretter vores byer og boliger på, har stor betydning for vores forbrug. Hvis vi skal nå vore egne målsætninger om at begrænse miljøbelastningen, må vi tænke nyt. Der ligger en stor udfordring i at minimere energi- og ressourceforbruget i anlægsfasen og driften af vores byer. Derfor er ressourcebevidst planlægning og design med fokus på arealforbruget centralt i udviklingen af Fremtidens Forstad.
Hvordan kan vedvarende energi gøres til den foretrukne energikilde?
Hvordan gøres det attraktivt at reducere energiforbruget i private husstande?
Hvordan nedbryder vi de barrierer, som forhindrer, at de mange progressive initiativer indenfor miljørigtigt byggeri omsættes til praksis?

I de kommende år vil de ældre komme til at udgøre en større del af befolkningen, end de gør i dag. Denne ændring i befolknings-sammensætningen får konsekvenser for hele samfundet, og i forhold til bylivets tilbud og funktioner er det en vigtig pointe, at fremtidens ældre er nutidens unge! Disse temaer er relevante, da de stiller nye krav til den måde vi tænker både byer og boliger på. Fremtidens Forstad skal være en by hvor mobilitet og nærhed er vigtige kvalitetsparametre.Hvordan sikrer vi, at det stigende antal ældre får opfyldt de nødvendige behov, uden at det kolliderer med, eller indskrænker andre gruppers behov?
Hvordan kan byplanlægningen bidrage til at aktivere den ressource, som de ældre udgør for samfundet selvom de har forladt arbejdsmarkedet?

BRIGHT GREEN
Begreberne bæredygtighed og bæredygtig udvikling er de seneste år blevet omdrejningspunkt for diskursen omkring den menneskelige civilisations påvirkning af kloden, dens følger og hvordan disse problemstillinger håndteres i fremtiden. På grund af begrebets uklare definition knyttes bæredygtighed i manges bevidsthed stadig til traditionel miljøaktivisme, der orienterede sig mod bagudrettede løsninger. Men indenfor de sidste år er mange miljøforkæmpere begyndt at orientere sig i den modsatte retning. Som kontrast til de mere pessimistiske fremtidsudsigter blev den nye bevægelse døbt Bright Green. Her er målet at opnå økologisk bæredygtighed uden at reducere, ja snarere øge, potentialet for økonomisk vækst. Bright Green betragter teknologien som kilden til de kreative løsninger, der kan skabe de nødvendige forandringer i vores samfund. I dette lys kan en bæredygtig udvikling realiseres ved at benytte sig af videnskabelig forskning, innovativt design og kulturel evolution som redskaber.
