In Northeast India, there are beautiful strong bridges that are built by the roots of the Ficus elastica (an Indian Rubber Tree) guided by the Betel Nut Trunk to create its structure. These bridges take 10 – 15 years to create.

“The EDITT Tower (Ecological Design In The Tropics) is set to be built in downtown Singapore. It’s design integrates a gray water system, central recycling, passive heating and cooling and solar panels. Half of the surface area of the building will be covered in local, organic vegetation. If that isn’t enough, sewage from the building’s inhabitants will be converted into biogas. Go Poo Power!”

Scientists have invented a material that converts absorbed heat into energy without pollution. The average car engine wastes up to 60% of the power it produces in the form of waste heat and uses only 25% of it’s energy to actually power the car.
Dr. Joseph Heremans of Ohio State University has recently developed a thermoelectric material that outperforms the previous leader by 2:1. Entitled thallium-doped lead telluride, the material promises to make cars and other engines more efficient by capturing waste heat without the use of moving parts. Moreover, it operates best between 450 and 950 degrees Fahrenheit, which is a typical temperature range for such engines.
According to Heremans, “The material does all the work. It produces electrical power just like conventional heat engines – steam engines, gas or diesel engines – that are coupled to electrical generators, but it uses electrons as the working fluids instead of water or gases, and makes electricity directly.” “
Our urban environment has causes our creeks to be un-drinkable, un-swimable, un-fishable. For example, each time we brake our car, little tiny particles of copper scrape off and fall onto the pavement. Multiply that by # of cars on the road with the # of times each car brakes per day and the number of days people drive. .. this, along with all the other shit we spill, drop, and emit flows directly into our creeks because it would cost too much money to filter in addition to our huge sewage treatment facilities and it would run the risk of overflowing poopoo-water into the bay during a heavy storm.
Some good folks in Australia and New Zealand came up with a good solution; permeable pavement that filters pollutants! This way, the soil underneath the pavement would absorb the water as opposed to washing it all down the storm drain directly into our rivers. Also, it would water the plants in the area and replenish our much needed groundwater supply.
Permapave Stormwater Filtration Grates allows water to flow through at 30 liters (7.9 gallons) per second, preventing “Gross Pollutants” such as plastic bags, gum, McDonalds wrappers, bottle caps, etc. from entering our natural water system. If combined with a Permapave curbside or bioretention system, it filters up to
60% of phosphorous,
70% Heavy Metals, and
98% Hydrocarbon from stormwater,
And like any filter, it needs to be replaced or cleaned. In this case, they sell a powerful, portable vacuum that sucks up 100% of the contaminants in one swipe.
Here are some designs for how it can be used in our streets.

so far I’ve seen many permeable concrete products, but this is the first I’ve seen that filters pollutants before contaminating the soil and our groundwater supply. If you find any more, let me know!
(this video is so long.. start from 0:11 to see it, then go to 0:30 to see how it works)
These Bike Trees are used by swiping your smartcard, which you’d pay monthly/yearly for membership. They’re starting to set up a network of these in S.F. so they can have a bike program like carshare. They’re still figuring out the details of the program, networking, and prices (so maybe you can influence their decisions by sending them comments!)

They are powered by the sun. yea!! The canopy protects bikes from rain and their height protects them from bike theives! they also got an automated security camera on there.
This guy, Abhinav Dapke, came up with the idea of having a pad for your fingerprint to secure the bike. i like this idea better cuz that way, the bike tree is for anyone to use! i also like the scale of these lil six-bike trees (they need to add some canopies)
Bike Tree proposal by students, Chun Yeug Cheng and Ka Fai Lee, from University of Hong Kong!
I like this design cuz lots of bikes on one tree!! and it’d be cool to have in a public space. (if on grass, probably need to have some paved areas around and to the tree, which could look cool too) I have no idea how you’re supposed to get it up or down.. (if anyone finds info on that, let me know! i searched for a good 20 min, but no luck)
this proposal was submitted for a 2006 competition called Reinventing the Bike Shed, held by Architects at Feilden Clegg Bradley Studios(check’em out, they’re labeled as sustainable, “community architects”)
Moskow Architects, who won the competition, proposed a conveyor belt style bike rack called H.U.B. (Habitat for Urban Bicyclists). 2006 Press Releases stated that as the winner, their design would be built in Southwark, London and if successful, it would be replicated all over London; however, that was two years ago and I haven’t been able to find any photos of it anywhere. Not dissing it.) It looks like a rack at the dry cleaners.
A finalist, Anthony Lau came up with Clamp-On Cycleloops, steel tube bike racks which are easy to install and secure onto existing infrastructure such as lamp posts.

In terms of efficiency, cost – how many bikes it stores, and public pleasure factor, i think Bike Trees and Bike Towers are winners,
however, my favorite is the one below.
Gavin McIntyre, and Eben Bayer invented Greensulate in 2006 when they were seniors at Rensselaer Polytechnic Institute in Troy, N.Y.
It’s organic, biodegradeable and the ingredients are simple: water, flour, oyster mushroom spores and perlite.
It is also highly fire-resistant, especially compared to your typical foam insulation
They are currently testing to make sure that mold does not grow even when saturated with water.
“The insulation is created by pouring a mixture of insulating particles, hydrogen peroxide, starch, and water into a panel mold. Mushroom cells are then injected into the mold, where they digest the starch producing a tightly meshed network of insulating particles and mycelium. The end result is an organic composite board that has a competitive R-Value a measurement of resistance to heat flow and can serve as a firewall.”
