PEOPLE AND PLACES: New York’s new skyline revealed:LA to San Francisco in half an hour moves closer

LA to San Francisco in half an hour moves closer: Over 100 engineers are now working on Elon Musk's 760mph supertube

Musk is working with UCLA researchers to develop system
Over 100 engineers have created crowdsourced firm to work on idea
Hoped the system could be rolled out in cities around the world

When it was launched, it seemed little more than a pipe dream.

Billionaire inventor Elon Musk unveiled a futuristic plan for a new type of transport that would shoot capsules of passengers along a tube at around the speed of sound.

Elon Musk, one of the brains behind the online payment system PayPal, and SpaceX claims his solar-powered 'Hyperloop' could herald a revolution in travel.

The Hyperloop Transportation Technologies design for Elon Musk's Hyperloop. It hopes to produce a technical feasibility study finished in mid-2015.

The team believes the system could link the majority of America's major cities together.

THE HYPERLOOP: HOW IT WORKS

Inside the tubes, hyperloop pods are mounted on thin skis made out of inconel,an alloy already used by Musk's SpaceX firm that can withstand high pressure and heat.

Air is pumped into the skis via small holes to make an air cushion, and each pod has air inlets at the front.

An electric turbo compressor compresses air from the nose and routes it to the skis and to the cabin.

Magnets on the skis, plus an electromagnetic pulse give the pod its initial thrust; reboosting motors along the route would keep the pod moving at just below the speed of sound so the system does not produce sonic booms.

Musk believes it would take just 30 minutes to travel the 381 miles from Los Angeles to San Francisco – half the time it takes in a plane – and likened the passenger experience to Disneyland's rocket ride Space Mountain.

Now, the plans are beginning to take shape.

A new firm, Hyperloop Transportation Technologies, is developing plans to makes the tubes a reality - and it has recruited experts from around the world.

The crowdsourced firm has around 100 engineers on the projects, and nearly all of them have day jobs at companies like Boeing, NASA, Yahoo!, Airbus, SpaceX, and Salesforce.

Dirk Ahlborn, the CEO of the new company, says it seemed the perfect way to develop the plans, with a site called JumpStartFund that aimed to crowdsource ideas.

He got in touch with SpaceX, Musk's firm, and the work began.

The team includes about 25 UCLA graduate architecture students at a facility in Playa Vista, although most members work remotely.

Ahlborn hopes to have a technical feasibility study finished in mid-2015, according to Wired.

So far, the team has made progress in three main areas: the capsules, the stations, and the route.

'They look at this like a blank sheet of paper on which they can realize their fantasies,' UCLA professor Craig Hodgetts said.

Musk's idea is based on the pneumatic tubes that fire capsules of paperwork between floors in offices. In this case, the capsules would carry people – even cars – in low-pressure tubes to minimise turbulence and maximise speed.

On top of pylons is a hovering capsule inside a low-pressurized tube, which can reach speeds of up to 760 mph.

'The only resistance would be the air in front of the capsule, which we moved to the back by using a compressor,' Hyperloop CEO Dirk Ahlborn said.

At its launch, Musk described the Hyperloop design as looking like a shotgun, with the tubes running side-by-side for most of the journey, then closing at either end to form a loop.

Trains of capsules would shoot through the almost air-free tube at up to 760mph,

accelerated by magnets which would also keep each pod on a steady course.

Each capsule would float on a cushion of air it creates as it speeds along – similar to an air hockey table.

So far, the team has made progress in three main areas: the capsules, the stations, and the route.

The proposed route of the firstHyperloop follows Interstate 5, which runs through the agriculture-richCentral Valley in California. It would take seven to ten years to build.

Capsules carrying six to eight people would depart every 30 seconds, with tickets costing around £13 each way.

In his proposal released online, Musk wrote: 'Short of figuring out real teleportation, which would of course be awesome (someone please do this), the only option for super-fast travel is to build a tube over or under the ground that contains a special environment.'

The proposed route of the first Hyperloop follows Interstate 5, which runs through the agriculture-rich Central Valley in California. It would take seven to ten years to build.

Musk put the price tag at around £4billion but pointed out that that is around one-tenth of the projected cost of a high-speed rail system that California has been planning to build.

However, transport experts received the proposal with scepticism, citing barriers, such as the threat of earthquakes in the region.

Musk has said he is too focused on other projects, for example his rocket building company SpaceX, to consider building the Hyperloop, and instead is publishing a design that anyone can use or modify.

Musk said he started thinking about the idea when plans for a 130mph (210km/h) high-speed train connection between LA and San Francisco were revealed, but now he has detailed his own version on Tesla's site.

'Flight' of the future: The hyperloop will travel the distance between Los Angeles and San Francisco in only 30 minutes

Smooth ride: 'It would have less lateral acceleration which is what tends to make people feel motion sick than a subway ride, as the pod banks against the tube like an airplane,' creator Elon Musk said

'I originally started thinking about [Hyperloop] when I read about California's high-speed rail project which was somewhat disappointing,' he told a Google Hangout with Richard Branson last week.

'It's actually worse than taking the plane. I get a little sad when things are not getting better in the future.

'Another example would be like the Concorde being retired and the fact there is no supersonic passenger transport. I think that is sad. You want the future to be better than the past, or at least I do.'

The entrepreneur made his fortune with the internet payment system PayPal before switching his skills into developing the new Falcon rocket system for Nasa and the Tesla electric car.

Mr Musk claims Hyperloop would be a practical solution for city pairs separated by 1,000 miles (1,600km) or less. Beyond this distance, it would be better to take a plane, he explained.

Unique: Travellers would enter aluminium pods which are mounted above the ground on columns 50 to 100 yards apart

Modern: This image shows how people would travel in the pods

But for the shorter distance, his new concept would beat the plane, he argues, because it would not waste time ascending and descending.

'You want a transport system that is roughly twice as fast as the next best alternative, that costs less, that is safer, that is not subject to weather and is more convenient,' Mr Musk said.

'If there were such a thing, I think most people would take it. In fact, it would increase the travel between the city pairs because of the increased convenience.'

Experts say Musk's track record could help the plan become a reality.

'Hyperloop is quite an old science fiction idea but Elon Musk is the sort of man who could make it work,' said physicist Martin Archer from Imperial College London.

Built to last: The inventor boasted that the tracks would be immune to weather and earthquakes, though it is not immediately clear how so

Creature comforts: The legroom is said to give would-be passengers a disruption-free ride

'He's the guy who made electric cars go fast with Tesla, which many people didn't think would be possible; and he's the head of SpaceX which is the only commercial rocket builder that has managed to hook up with the International Space Station.'

Musk says he will leave it to others to build the system initially.

'I have to focus on core Tesla business and SpaceX business, and that's more than enough,' he told investors of Tesla, his electric car firm.

'If nothing happens for a few years, with that I mean maybe it could make sense to make the halfway path with Tesla involvement,' Musk said.

'Hyperloop consists of a low pressure tube with capsules that are transported at both low and high speeds throughout the length of the tube,' Musk said in an exhaustive paper detailing the system posted online.

'The capsules are supported on a cushion of air.'

Each of the capsules is pressurized, and Musk says they have an emergency braking system as well as a reserve air supply in the event of an emergency.

There and back: The 'loop' portion highlights the fact that there would only be two stops

He admits the scheme came from a disdain for current systems.

'When the California 'high speed' rail was approved, I was quite disappointed, as I know many others were too.

'How could it be that the home of Silicon Valley and JPL – doing incredible things like indexing all the world's knowledge and putting rovers on Mars – would build a bullet train that is both one of the most expensive per mile and one of the slowest in the world?'

Musk claims the scheme can power itself through solar energy.

'By placing solar panels on top of the tube, the Hyperloop can generate far in excess of the energy needed to operate.

'This takes into account storing enough energy in battery packs to operate at night and for periods of extended cloudy weather', he claims.

New York’s new skyline revealed: The towers that will transform the city by 2030

The most obvious difference will be 57th Street, which will host the tallest buildings in the Western Hemisphere
Named Nordstrom Tower, but referred to as 217 West 57th in the graphic, it will reach a height of 1,795 feet
As well as the Nordstrom Tower, the graphic includes the Moma Tower, One Vanderbilt, and 15 Penn Plaza
But it doesn't show the new World Trade Center, along with large projects in Midtown and on the Far West Side

'Billionaires' Row' is transforming New York's iconic skyline.

By 2030, architectural giants such as the One World Trade Center and One57 will be overshadowed by a new crop of glistening towers in Midtown Manhattan.

Now, one art studio has created a rendering of what the New York skyline will look like in 15 years once these towering behemoths make their mark on the landscape.

The image shows what Midtown Manhattan will look like in 2030. Slide left to view the locations of some of the iconic towers currently under construction in the city. One of the most obvious additions will be the Nordstrom Tower, which could reach 1,795 feet - around 15 stories higher than the World Trade Center. In the graphic the Nordstrom Tower is labelled as 217 West 57th Street

The most obvious difference between today and 2030 will be 57th Street, which will host the tallest buildings in the Western Hemisphere.

Dubbed Nordstrom Tower, the tower's parapet could reach 1,530 feet — 15 stories higher than the World Trade Center — and its pinnacle, roughly 1,795 feet. Previous plans had suggested the tower would be slightly smaller, at 1,775 feet.

Nordstrom Tower is labelled as 217 West 57th Street. Once it is completed, the building will have a giant seven-floor Nordstrom department store on the lower levels and residences above.

It will stand more than 300 feet taller than any other man-made objects in Midtown and will likely cast a few shadows on Central Park, which is near its base.

NO MORE BRIGHT LIGHTS, BIG CITY?

Bright lights, big city? Not so much, if a New York City council member gets his way.

Councilman Donovan Richards Jr introduced a bill requiring most office high-rises to turn off the lights at night as a way to cut energy costs and help migratory birds.

'We need to be doing everything we can to conserve energy,' he said. 'This is a commonsense measure. It's not going to cost anybody a lot of money.'

Seventy-one percent of New Yorkers like the idea, according to a Quinnipiac University poll of 969 registered city voters.

The Moma Tower at 53 West 53rd Street is also seen, and work for that building is currently underway.

The image, by VisualHouse, doesn't show the new World Trade Center along with several large projects in Midtown and on the Far West Side.

It also omits 220 Central Park South and 1710 Broadway, which is currently in its initial planning stages.

'The studio has worked closely on the city's most prominent upcoming projects, including Hudson Yards, One Vanderbilt…217W 57th St' the company writes on its website.

'The still production team at VH New York engaged they're project specific knowledge to create this inspiring future cityscape image.'

In terms of bulk, the new Hudson Yards will be the biggest change to the skyline, according to New York Yimby.

Hudson Yards will create 17 million square feet of commercial, residential and retail development over a 28 acres with 5,000 new residences and 100 new shops

It is the largest private real estate development in the U.S, with nothing done of this scale since Rockefeller Center was constructed in the 1930s.

The rendering also includes One Vanderbilt and 15 Penn Plaza. Earlier today, New York City officials approved plans for One Vanderbilt after the developer made an unusual tradeoff: a promise to make sweeping upgrades to nearby Grand Central Terminal.

In exchange for getting more square footage, developer SL Green Realty will invest about $220 million in critical improvements to Grand Central.

This would allowing more trains to run during rush hour on the clogged 4-5-6 lines, which carry more people per day than the entire transit systems of Chicago or Washington, DC.

'This is the first time we've seen vast private investment to improve mass-transit access,' said Mitchell Moss, a professor of urban planning at New York University.

It will transform the stodgy East Midtown area, where the average building is 75 years old and saddled with outdated structural features such as interior columns and low ceilings.

Anchored by tenant TD Bank, the building is expected to house about 8,000 workers when fully occupied.

The tower will house a gleaming new transit hall that will funnel workers directly into Grand Central and also provide a crucial direct link from commuter trains.
