They want to take an inefficient process and turn it into three processes. Instead of having the offsite wind turbines directly supply their electricity into the power grid, they elected to have the wind turbines produce electricity to produce hydrogen gas to transport to the site and produce electicity again. I would think that at most this elaborate scheme is half as efficient as directly supplying the power grid with clean energy. If they really wanted to have the WTC site be associated with green building, then why didn't they allocate money to build wind turbines elsewhere and claim that the site is funding clean energy or specify that the site only buys renewable energy from the energy company? Instead they created this fuel cell idea to make sure everyone knew these buildings run on clean energy.
It's my understanding that the World Trade Center project is financing the turbines and the hydrogen production equipment in addition to the fuel cells so they're paying more to get less energy? It certainly doesn't make any sense from an engineering perspective which proves it's politically driven like everything else in New York.

Next person to continue the "whose a new yorker and who is not a new yorker" arguement--that has nothing to do with the construction of tower 4 is getting penalized.

That's one week from today. Finally we get to see a tower crane at Tower 4.

Weren't they supposed to install it back on the 14th? I wonder what happened and what the odds are we'll actually see it installed this time?

More setbacks on this tower would have been great. This way it looks pretty boring, missing any special structure or facade to it.

I just hope for hiqh-quality cladding and the whole architectural ensemble of the new WTC to turn out great.

DIG THIS: Workers on the 64-story WTC Tower 4 have moved on to the long-awaited superstructure.


Don't look now, but that's a real Tower 4 - oops, 150 Greenwich St. - getting built at Ground Zero's southeast corner.

The photo on this page clearly shows that work on the first of Larry Silverstein's World Trade Center skyscrapers has moved from the foundation to the superstructure stage.

The boxy structures on the floor of the pit are the first stage of what will be the concrete core of the 64-story, 1.8 million square-foot tower, designed by architect Fumihiko Maki and expected to open in 2012.

Concrete for the building's basement and part of the core was poured in the past two weeks. It's unclear when structural steel will rise, but Silverstein has ordered enough for the whole job.

When completed, 150 Greenwich St. will be the new home of the Port Authority, which has committed to leasing one-third of its space. Silverstein also has an option to "require" the city to lease 600,000 square feet more.

The project isn't entirely out of the woods yet. A "soldier pile" wall built by the Port Authority to shore up the earth beneath the No. 1 line subway "box" oversteps a segment where some of the tower's footings will go on the western side.

Sources said Silverstein and the PA are working together to resolve the issue.

Matters involving security, underground vehicular access and utilities also need to be worked out.

But after years of little activity in Ground Zero, it's heartening to see Tower 4 and the PA's Freedom Tower pushing ever so slowly skyward.

It's only 80 feet below street level, I'm pretty sure their will be 4 basement levels (similar to all the rest of the WTC towers).

Will they connect the underground floors of tower 2, 3 and 4? It would result in a large parking garage.

Maybe it will be at street level by the end of the summer, lets cross our fingers and hope.

they said it's will be so I'm 99.9% sure it's going to happen. Liverstein wants this tower up asap.

Yes they will all be interconnected with two levels of shopping space around pedestrian commons underneath. It all ties into the new PATH terminal which will have its own underground connections to the WFC and to the Fulton Station subway terminal to the east.

There won't be any parking because of security reasons, especially the first bombing of the WTC. There will only be vehicle access for deliveries (and I'm sure some VIP's) but there won't be any general parking. Only shops and transit terminals as mentioned elsewhere.
