Business 2.0 has a inspiring story of EnviroMission and its Solar Tower.
EnviroMission is founded by Roger Davey, a previous stock broker who got interested in this German design. After securing licenses for Australia, US and China he has set about commercializing this technology for many years now.
It is listed on the ASX.
The initial plan was to build a 200 MW plant which has been scaled down to 50 MW. The initial tower may have looked like the one on the right side. This could have been the largest man-made building in the world.
Apart from the risk in the technology, just building the Tower would have been an engineering marvel. However, Davey is confident that this will happen.
“The tower will be over there,” Davey says, pointing to a spot a mile distant where a 1,600-foot structure will rise from the ocher-colored earth. Picture a 260-foot-diameter cylinder taller than the Sears Tower encircled by a two-mile-diameter transparent canopy at ground level.
About 8 feet tall at the perimeter, where Davey has his feet planted, the solar collector will gradually slope up to a height of 50 to 60 feet at the tower’s base. If Stanley Kubrick had put a power station in 2001: A Space Odyssey, it would’ve looked like this. Acting as a giant greenhouse, the solar collector will superheat radiation from the sun. Hot air rises, naturally, and the tower will operate as a giant vacuum. As the air is sucked into the tower, it will produce wind to power an array of turbine generators clustered around the structure.

The interesting aspect of the program is that Davey is confident that they can compete “with the coal people”. To make his dream possible, Davey is securing support from a varied set of companies and people.
Davey has also secured the services of Macquarie Bank, one of the country’s most prominent investment banks and a financier of major infrastructure projects in Australia and overseas. Companies like General Electric (Charts) and PPG Industries (Charts) are providing free design services – with the expectation, obviously, that they will win contracts to supply components for the solar tower.
The latest believers are the Chinese. IN 2002 executives at Xiang Jiang Industrial, a Shanghai developer and construction company, stumbled across press mentions of the project. They flew to Melbourne to meet Davey and learn more about the technology.
Xiang Jiang subsequently became EnviroMission’s second-largest shareholder when its Australian holding company invested $1 million in EnviroMission and $1 million in SolarMission Technologies, the vehicle for Davey’s U.S. operations.
The Chinese also invested $8 million in a joint venture with EnviroMission to build and operate solar towers in China. “We truly believe the technology will be successful,” says Yue Tang, a Xiang Jiang director. “Every country needs renewable energy, and China will be a big market.”
The joint venture has applied to build a 200-megawatt, half-mile-high solar tower outside Shanghai. “We want to build the tallest in the world,” Tang says. “Reaction at all levels of government and from technical officials is all positive, but because this is a new technology, they still need more technical information to get final approval.”
With a huge renewable energy target China is a great place for staring project like these.
China’s renewable-energy target represents about 60 gigawatts. Australia’s total energy production is about 45 gigawatts.
