just a shame that we haven't figured out a way to make electricity from sunlight that doesn't require such a toxic waste stream in the manufacturing process. when I see large PV projects, I've just got to wonder whose fishing waters are glowing in the dark because of it...

The Truth — Fri, 22 Aug 2008 04:24:20 -0000

Sorry to disappoint you folks but the story behind the Sanyo`s solar power is much different than you imagine, I know that (without going into details) because I worked there. The truth is .... A Sanyo salesman made an error on an production order for one of his customer (let`s say the customer order 1000 solar panels and the sales guy add 1 more zero), after that and almost at the same time the president was going to a trip by shinkansen which passes in front of the old factory (where today is located the solar panel) and thought that something need to be done in order to "hide" the old factory looking ... therefore, he used the mistaken order (taking out from the "9000" solar panels left) to cover up the factory from shinkansen view. I know, sometimes the reality hurts and destroy dreams but that is what happen.

That's really amazing!
Japan is really playing with creative ideas (to be precise:a big international corporation).
I'm sure the USA is going to see loads of similar new renewable miracles, after the election, though.

Just like the unit's name implies, KiloWattHours are made by multiplying a value in KiloWatts by a certain number of hours. If you want to know the rate of energy being produced, you need to divide it by time, just like metres per second (m/s) KiloWattHours when divided by time gives us KiloWatts which is a rate of energy production. A value expressed in kWh has a different meaning without the number of hours involved.

Imagine I said that my car can travel 10,000km. This doesn't tell us anything about the speed of the car until we know the time frame. 10,000km per year is fairly normal, 10,000km per day is quite fast. 500,000kWh per year is pretty good, 500,000kWh per century is not so good.

kWh are a unit that most people find rather confusing unit, much like Nm (Newton Metres) which are found my multiplying Newtons (a measure of force) by metres. I suspect this is because we are more used to measuring rates expressed as one unit divided by another, not just a bare unit or a unit multiplied by another. I hope I have cleared things up a little.

What all this means is that the panel doesn't have to be 1133 metres tall, it only needs to be 10 metres tall as long as it's out in the sun for 113 hours. Of course, in reality, it actually extracts less energy than the theoretical maximum and runs for more than 113 hours per year.

There are many more details at http://www.solar-ark.com/english/about/spec.html but to clarify some of the details mentioned in this blog, the outputs are 630kW and 530,000kWh per year. The actual usable power is 2x 300kW at 440V AC.

Although this is pretty cool, some of the best improvements to buildings can actually be made without solar panels at all. The building behind the solar array looks like it has been designed with passive solar collection in mind. Large glass windows to let in light and avoid needing artificial light, insulating glass to avoid needing costly heating and cooling and passive air-flows through the building to reduce the need for fans to move the air. It's amazing that for about 10% extra building cost, you can reduce the running costs of a building by 50% and save enormous amounts of energy at the same time.

Impossible.
The most optimistic number that I can find for solar energy density is 1.4 kW/m^2. So for 500 000 kWh
(That’s 500 Mega Watts) you would need an area of 357142.9 square meters.
Follow the more info link and we find that the panel is 315 meters long that leaves the height at > 1133 meters!
Maybe it’s just the camera angle but it doesn’t look that tall to me.

We can so build stuff like this. Look at the Googleplex with a total capacity of 1.6 megawatts!!!

Delete my last comment and just tell chris sachs that he needs to take a physics course. It's much more suitable to the topic here.

Americans could easily build it.
But not without making the last couple dozen years absolutely meaningless.

How durable is this building? It's awfully complicated, with a lot of moving parts, which is cause for concern due to the increased likelihood of problems arising. I think this may get very expensive to maintain.

That aside, this is one cool building!

Oh, and does the government of the country that produced this town have anything to do with constitutional libertarianism? Ron Paul?

You think Ron Paul, ultra fundie Xtian racist who thinks Alabama and Mississippi had the right to decide that blacks shouldn't integrate and abortion is murder, is gonna build that?

Put the bong down hippies....

hristopher Sachs says: January 9th, 2008 at 5:43 am Generates 500,000 kWh? I think you mean 500,000 kW (kilo-watt-hours is an amount, kilo-watts is a rate). It’s like saying Arnold Schwarzenegger is so strong he can lift 60 inches! 500,000 kWh isn’t a lot of energy. But 500,000 kW produced cleanly and sustainably is a lot of power.
==============================

Huh? Why do KWh go over the heads of so many people. A kilowatt-hour is a kilowatt generated for an hour. For instance, leaving a 1kw microwave on for an hour. That is 1kw/hr of electricity. 10c if you're using fossil fuels.

The key to this is... how long does it take to produce the 500,000kw/hrs? Obviously it's not producing a half million KW every hour or even every day, that'd be an insane amount of energy.

Is it per month? Per year? :)

Why are we not doing this too. How long are we going to be known as the idiots in america?

what makes it so hard for other countries to construct this????????
especially the netherlands

RON PAUL for president!!! (forgot to add that to my previous post) =)

Of course it generates more power than it consumes. Even if it consumes more, who cares, solar energy is free for life because James Bond has shutdown the one and only solar blocking satellite built by the crazy villains.

Sako, we have the coolest military gear though! Imagine what we couldv'e built for a trillion $$$ instead of war? Ron Paul for president!

Great pictures! I am also wondering about the amount of power it consumes compared to the amount it generates. Either way, nice find.

Re: The World’s Coolest Solar Collecting Building?

Tue, 08 Jan 2008 21:34:23 -0000

Cool!!! But, my question, does it generate more power than it consumes (what with being a building for environmental friendliness and all)?

this is the coolest thing i ever seen. Its a shame to us Americans, that we can't build this kind of buidings in America.
