Real Life Science-Fiction: The Photovoltaic Nanoparticle Ink

Etienne Giroux — Tue, 25 Aug 2009 15:23:22 +0000

Silicon-based solar panel are expansive. So expansive that they can't compete with the fossil fuels in terms of efficiency and cost of the installations. This could change, though, because researchers are making progress in the paintable solar cells area. This "ink" could be applied on any surface: roofs, walls and even windows, as the ink is semi transparent. Even if the project is not near completion, the scientists achieved a 1% turnout on the solar power, and according to them, achieving 10% would be sufficient for commercial use.

Is Gmail the World's Greenest Email Service ?

Etienne Giroux — Mon, 24 Aug 2009 19:11:10 +0000

Google's web mail service could be the greenest one you can use for your business or personal emails. The computer and technology spheres aren't often seen as green because of their energy use and materials used in their fabrication. Google's servers have a very good Power Usage Effectiveness (PUE) rating ( and most useless components (like graphical components on monitor-free servers) are stripped out for less power use. They have a 1.1 rating where the best possible rating is 1.0. For reference, Microsoft's PUE rating is 1.6, which is also considered quite good.

Etienne Giroux — Fri, 21 Aug 2009 18:54:52 +0000

Top 29 Reason Why Being a Part-Time Entrepreneur Sucks

Etienne Giroux — Thu, 20 Aug 2009 19:00:00 +0000

The Happy Rock wrote a list of why they think it sucks to be a part time entrepreneur. Of course, something of that importance is usually a full-time business, but not everyone is able, or wants, to jump off the wagon and start something new, there is too much risk involved. The list is long, and while all points are valid, I collected what I think are the most interesting points made.

You Aren't Crazy, You're Just an Entrepreneur

Pamela Slim wrote an article on the hardships and the phases any entrepreneurs goes through. She defines the characteristics, things to remember and the "mantra" of each phase to reassure you what you're going through is normal.

The four phases she mentions are the following:

Square one: Death and Rebirth

Square two: Dreaming and Scheming

Square three: The Hero's Saga

Square four: The Promised Land

Garbage Tracker

Etienne Giroux — Wed, 19 Aug 2009 19:30:00 +0000

A team of researchers at MIT are working on Project Trash Track. The project is exactly what its name implies. They use special electronic tags to track waste in New York and Seattle to find out where the trash ends up.

Project Trash Track wants to create awareness of garbage-disposing facilities, to avoid the "take out and forget about it" aspect of garbage collecting. Following the garbage and finding out its final resting place creates a feeling of responsability for the people.

Here are some of the ideas I thought were the most interesting:
