Several past Olympic hosts have promised greener events, but Rio de Janeiro could set a new standard with a solar-powered artificial waterfall building that operates day or night. The eye-catching Solar City Tower represents one of the standout entries in the International Architecture Competition for the Olympic Games 2016, according to TreeHugger.
The tower uses many solar panels and a solar power plant to produce energy for the Olympic village by day. Any excess energy goes toward pumping seawater up into the tower for storage, so that it can be released by night as a spectacular waterfall. The falling water would also help turbines create electricity for the nighttime village.
That neat energy storage scheme proposed by the Swiss firm RAFAA is similar to many that exist for solar power or other renewable energy today, except on a much larger scale.
Anyone not impressed with either the energy solution or aesthetics can still enjoy social gatherings and events held within an indoor amphitheater, along with a cafeteria and shop situated beneath the waterfall. Bolder visitors can catch a breathtaking 360-degree view of the city from the observation decks and urban balcony, or even do a little bungee jumping from 90 stories up.
Rio de Janeiro has already promised the first zero-carbon Olympic Games, and started by planting 3,580 saplings last September to offset all the carbon emitted during the city's bid to host the games.
Is there really going to be excess energy left over from the solar generation after electricity usage??? Maybe. Enough to pump the amount of water necessary to create more energy to light a city at night? Hardly!
Would be more impressive if they just continuisly used the solar power to pump the waterfall, that way you can see it day and night. Just build enough solar panels to produce power for both---its still green.
God cant anyone in this world get it straight?? Just use continual suction from a vacuum Powered by its own damn kinetic energy!! if you place a finned generator in the wake of the water intake of the vacuum all you need to do is have the initial energy to start the suction and BAM instant renewable power. the best way to achieve the initial energy would be a direct current battery that can be recharged by the vacuum generator, the waterfall could still cascade down also why don't these techs use the water to land on multi-Finned generators? the concept is great but the design is just drab and flawed..Get it together people! i know the waterfall has generators now but... why only at night?? Ugh
sorry, but i call bullshit!
seems a little 'perpetual motion' to me.
maybe i underestimate the output of today's solar tech, but
it just seems like it would require a solar plant larger than the island to pump the water up.
then generating energy with the falling water is just reclaiming some of the energy wasted by pumping the water up, but its not going to generate any more energy than was put into the system. i hope they have LED lighting there, they're gonna need it. you know they should just put a dynamo in every seat and let the audience crank them. or shaking a magnet through a coil like those flashlights. either way, they would have saved some $ lol okay my idea wasnt any better than theirs i was just making a funny
lol that was funny but the perpetual motion could work but still hahaha
Although it would waste energy to run the waterfall, it could be a clever way to hide the huge wall of panels.
That picture does the concept no justice. For one I see no massive storage in the upper to keep flowing all night long when off solar power. Even with reclaimed energy from turbines I think it wouldn't replenish demands more less power the city surrounding. Did I mention that picture has the waterfall facing out to sea? Who wants to buy a boat just to watch a waterfall? BTW- How tall is this thing supposed to be?
jeditalian - agree on making the audience crank!
This concept to me seems to be a little over the top. There are much simpler ways to have reusabel energy than a huge waterfall on an island!
