The best suicide technology in the world (nuclear technology?)
bloody000:
If you cover the parking lot with "trees" of that size it won't be a parking lot anymore: There's no place to park!
The author of that new design obviously saw this problem and scaled the trees(especially the panels) to a much bigger size, too bad he forgot about gravity, wind and maintenance(cleaning, repairing and replacing panels).
I never heard about the Netherlands utilizing tidal power for electricity, maybe they do have a few experiments, but obviously not very well known.

Bloody, please just..be quiet.

Doesn't change a thing as my article already stated that 25 years is expected lifetime, point is: you will not save any money during that time.

Tired and hung over right now. Ill write something anyways.
Due to my "super" math skills i might fuck this up :P
Not to mention how i "love" bills and theyre confusing explanations and numbers.
The power company where i live charge about 0.49 NOK / KWh (unless iam reading it wrong)
So if i used 442 NOK in power one month:
(442 / 0.49) / 30 = 30 KWh / day
The actual total of the power bill is 840 NOK. Its from december 2008.
Power cost over 25 years with the current prices: 700 NOK x 12 x 25 = 210'000 NOK
A Solaris power system:
5000W Inverter / controller 7'129$
4.85 x 5000 Solar panels 24'250$
Total: 31'379$ x 6.096 = 191'287 NOK
Norwegian(south) daylight hours:
December: 5:54
May: 22:13
Average: 28:07 / 2 = 14:03
Power system producing on 50% output for 14 hours:
5000 x 14 = 70'000 -6% = 65800 / 2 = 32900 ~32.9KWh
Notes:
You need a pretty big pile of cash for the initial cost.
Using solar power with todays tech is prolly not a good idea in norway due to little light.
A system like this will take up a good deal of space.
If something breaks and dont have a warranty the calculations fall apart.
Places with an abundance of power (like norway) are prolly not good locations for current solar panels.
Ive not included the cost of batteries or a battery system.
Storing power in batteries or hydrogen is not a good solution, batteries erode over time and hydrogen takes alot of space.
Prices typicaly rise slowly, so the power cost over 25 years will likely be higher.
Current affordable pv cells only have an effiency of 14-18%, in the future there will hopefully be better cells.
Final Conclusion: Its possible to have a system like this if everything is as its supposed to. It seems to work best in a place with many hours of sunlight and high power prices.
Do tell me if i made some mistakes, i hope i didnt xD

In other words you will still be using regular electricity and thus not save power. I believe you also for got the installation cost plus any maintenance that might occur. On other hand you will be limited to what you can do with that power. It's ok for a summer house where you need power for your cell phone charger, a lamp and a small tv. However in a real house where you spend you daily life, using things like an oven and many other electrical appliances at the same time, then the solar power becomes too unreliable.
