Bauhaus communal spirit in Vincent Van Duysen system. The system is called Infra-Structure and is designed for Flos. We worship the system’s simplicity and flexibility hence so few words.

Tesla Powerwall Explained (mostly to myself)

IMG_0037

This is a very subjective post. I was always very keen to know what Tesla Powerwall was, and never actually bothered to read or wiki or youtube about it. Musk made it equals ‘is cool’ means ‘heap’ stands for ‘someday maybe’ really deciphers into ‘not in this part of the world unless one is fabulously well off.’ Summoning my excited pessimism, I have rolled my sleeves up and typed ‘power wall’ in the search bar. Four days later I made it to my laptop again to see ten or twelve tabs all reading tesla power w… A weekend has passed and I made myself find time to read, watch and comprehend.

Then I sketched what I got from all of this (attached).

A) The Sun is needed and conventional grid works well too.

B) PV panels are required too to send DC current to a sleek looking like a model S P85D bonnet cabinet

C) Powerwall either stores or uses electricity.

D) Energy bill is affected: use an off-grid electricity supply from your very own Powerball during peak hours

Internet is a good source till comments start coming along. One is not enough some say. 3.3kW limits the number of appliances used simultaneously. You need to put several batteries together to get a decent household use, they add.

Hey, we might have forgotten: the first iPhone did not record videos too.

The first battery of the kind might be expensive and till date may not be the most practical yet it gives a chance to store your own energy. A user stops just buying a kilowatt that is instantaneously consumed. A user can keep her kilowatt, and if not used, sell it or exchange. This is an economy.

Light Pushes Wind

 

It’s fascinating to watch colossal wind turbines along the shores of Denmark or fields of the Netherlands. They add sleek extraterrestrial grandeur to a pastoral landscape. A windmill could raise as high as the thirty-storey building and produce up to 3.5 MW of electrical power (enough to power about 430 houses).

Spectacular as the windmills are, the Dutch design practice Studio Roseegaarde, turned a wind farm at Sint Annaland in Zeeland into a light installation. Green (ha, green energy, right!) laser beams fired by a smart tracking device aim at a blade of the next windmill  The device predicts accurate position of the blade and thus a seamless movement is created.

The project WINDLICHT can easily be a Kinderdijk of our connected time.

The UAE Sand to Store Solar Energy

I have already posted about a massive solar plant Shams in the UAE. Today we write about a related news. Masdar Institute informed they have found the possibility to use sand as a medium to store the heat from the solar plant.

Sand can potentially replace synthetic oil and molten salts used in TES (thermal energy storage) systems. The higher working temperature leads to cost reduction of storing and transmitting the energy.

What impressed me in 2015

This post has nothing to do with lighting per se. These are just few things that have produced a big impact on me during the last twelve months.

– Novel The Garden of Forking Paths by Jorge Luis Borges

– Song Ya Balad by Bachar Mar-Khalife

– Movie Bajirao Mastani directed by Sanjay Leela Bhansali

– Sensation of coming back to my hometown

– Free flight of an aerial flip in aikido

Happy New 2016!

Data Delivered by Light

light.chipsx299

This news appeared across tech media and geek blogs a couple of days before Christmas could have massive impact on the IT and light industry in already near future. A chip, combining optics and electronics delivers data faster and saves the third of energy for a data centre. ‘Optical connections can carry data faster than electrical ones consuming the same amount of power,’ state a group of researchers from MIT, University of California, Berkley, and University of Colorado, Boulder.
