A crash course in changing the world.

Okay so I had this thought. The winds that travel in between skyscrapers in big cities much reach colossal speeds, these winds could be used to generate energy. So why not install wind turbines in big cities? Here's a small render I made:


Simple enough? Well here are some problems:


Noise; from what I've heard wind turbines can be quite noisy, something that big cities usually have enough of.

Accidents; Wind turbines a prone to break when the winds get to high. Turbines can break and scatter parts. This would of course be extremely dangerous in big cities if people live or travel near them.

But if they were installed in places where people don't travel, like in secluded alleys, with some kind of protection around them, it might be safe.

Thoughts?

Random afterthought: 3 dimensional wind turbines? Hang them on an axis and the could turn with the wind, like a flag hanging on a flagpole. => More efficient turbines?

Very innovative!
If you're worried about parts flying off and noise..theres always kite generators..

Hey! I forgot about kite generators! Imagine putting kites on the highest buildings in New York! But what's good about my idea is that the wind gets pushed between buildings and should therefore achieve higher speeds, I think. :P

Very interesting concept . . . I like it. If the problems that you already pointed out can be solved then it´s a concept with a lot of future!!!

Why can't kites go between buildings? You've got poles sticking out from the sides of buildings, just replace the fan blades with a kite. Each kite generator comes with a computer that controls the kites motion to the nanosecond, set the limits and the kite will not be flying into buildings.

I think its a great idea. Large buildings also generate their own thermals, so maybe skyscrapers could have turbines sticking out parallel to the ground. The sound isn't necessarily a bad thing, its all how this are perceived--think the sound of sustainability. In terms of them breaking apart and killing people, yeah that's a problem. The kites are a great idea, maybe an alternative to turbines?

Keep me in the loop on this idea I think it's great. +1 spark

Per , its a good idea.... great place to start from.... lets do some real brainstorming on this one.... also you can see Architects are getting the idea to incorporate the towers with turbines built in here...

Neat idea. Chicago, "The Windy City" would also be a prime target for this sort of energy generation.

And why not solar on top of the buildings or some sort of way to catch heat being absorb and then radiated by all that concrete?

Great rendering lol Awfully hard on super heroes flying therough the city, though! Lots of great discussion points here +1 collaboration!

Great idea and rendering! I have walked down many city streets and the wind power is formidable. There must be materials and engineering to make this a real possibility - I would definitely pursue it!

I think using the urban heat island effect as thermal wind generation is brilliant. You don't have to worry about birds if you use Vertical Axis Wind Turbines. These look like VAWTs turned on their side...

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

Future

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
