EnviroMission, Ltd. (www.enviromission.com.au; US Stock Market: EVOMY, Australian Stock Exchange: EVM) is a renewable energy developer of sustainable “green” energy solutions for the energy market. EnviroMission aims to be one of Australia’s leading producers of clean renewable energy. EnviroMission holds the proprietary rights to Solar Tower technology, a large-scale renewable energy technology based on simple fundamentals of physics — hot air rises. Solar Tower technology has the potential to offer competitive renewable energy with equal reliability to fossil fuel generators. A single 200MW Solar Tower power station will provide enough electricity to power around 400000 households. The energy output will represent an annual saving of more than 1960000 tonnes of greenhouse CO2 gases from entering the environment when compared to brown coal emissions in Victoria. The greenhouse savings equate to the removal of approximately 500000 cars from the road. The Australian Solar Tower project consists of six distinct phases, the first two of which (project optimization and pre-feasibility commercialization) have already been completed. The third phase (final feasibility), paving the way for the implementation of the next three phases (final design, construction, and commercial operation).

EnviroMission via press release “EnviroMission Solar Tower Project Financial Commitment”. EVM has received a formal commitment to provide the entire development and construction capital for EVM’s first solar tower power station being developed in La Paz county Arizona to deliver the terms of a power purchase agreement with the SCCPA.
The financing is subject to the due diligence and the acceptance of related banking instruments by EVM’s legal adivsors and bankers…”100% pure equity”.
… and on the roof of the lower part can be fitted with solar panels.
BTW, if you haven’t seen the Discovery Channel segment on EVM, you may want to take a look at it. The animation of the tower helps create a visual perspective, despite the filming taking place in Australia.
The height of the tower provides greater velocity for airflow through the turbines. The original plan created a decade or so ago called for a very tall tower for optimum performance. EnviroMission has indicated in past press releases that the designs for the tower have a reduced height. For perspective, commercial building heights are increasing. The Burj in Dubai is 2,722 feet tall (829m).
but why does it have to be that tall
The difference in temperature from the base to the top creates a natural air flow with enough air speed to “spin” the turbines at the base of the tower, creating energy.
Pretty exciting PR found at the EnviroMission website: “Solar Tower Development Overview & 2012 Strategic Direction”. Slowly getting closer to the construction of a solar tower.
so what exactly is the purpose of the tube
I bought the “Solar Chimney’ book, It explains in detail, all of the details of the original experiment that was tested in Spain. It really nice that the outer edges can be used as a greenhouse , so not all the land is ‘wasted’ on the power plant. This is the most incredible solar design to date for a large-scale system! Thanks for sharing!
the one in Spain focuses the light from about 4000 mirrors onto a small spot at the top, where the immense heat powers a single turbine. The one show here just creates an up-draft of warm air, which is meant to power a number of fans at the base of the tower. The Seville system is much more efficient, as the temperature differential is higher and it can also be powered over night. see Gemasolar.
How is this different technically to the one they built in Seville, Spain?
You’re forgetting about maintenance & operation costs. There’s no fuel – solar energy is free.
Secondly – this idea seems to be very simple; it may be much affordable than nuclear. Question is: HOW MANY facilities like this can be built with cost of nuclear power plant?
First shot and i found that cost of building Nuclear PP is 4,5mln Euro (6,39 mln $) per 1 MW of power.
If THAT costs ~320 mln $ (inlcuding 4 times lower efficiency) it could be good idea.
its not always about being the most economical. its about sustaninability and affect on the environment. without enviornment, economy wouldnt exist.
Not economical or viable…
Nuclear Power Stations can generate 1280MW, This station would generate 200MW
The tower its self is larger than the Empire estate building by far
In seville spain, they have designed PS10 solar tower which is far smaller yet generates 300MW of electricity
Sorry but back to the drawing board
Beautiful.
can i build one in my back yard:)
i see your point. but the air always will be travling at 49 feet per second. and with the hight of the tower you could put at least 5 massive turbines in it. and also because of the heat at the bottem it could make energy with steam. there could also be soler panels. so woth all that it can produce the max amout of energy from the sun well producing all most no co2.
someday. someday i will put my name on the side of that. if its the last thing i do….
This music sounds like it came straight out of an educational video from the 1980s.
Good idea. Let’s privatize our roads, too. Heck, let’s privatize our governments.
1st ones gona be used to grow lots and lots of marijuana
I’d hate falling down that pipe…
Wait, thst video said the tower is that tall… WHAT THE HECK?!?!
That’s a hell of a lot of seran wrap! 😛
All it seems that it would do since their is no information is shoot any air or Co2 from the ground into the air….Seems rather useless unless it filters or does anything different than what it showed…Almost seems like just a big windmill to harness air..Don’t see how it reduces green house gases.
