What is 3D Printing and what is it for?

3D Printing is another name for a manufacturing method called Additive Manufacturing.

Using Additive Manufacturing, products are designed 100% digitally in a computer where users can design all the parts describing its physical characteristics. The design is then stored in a simple file and after clicking on "Print" the object is literally printed by a machine connected to your USB port or your local network. As easy as that. You can manufacture something with just a click of the mouse button.

How governments are accelerating global warming

A

ll around the world politicians are talking about global warming, but most of the time they implement policies that instead of helping to solve the problem, they are making it worse. And I am not talking about the sceptics politicians, or the ones that delay decisions because of economic reasons, I am talking about the ones that really believe the current facts. and think that they are helping.

Here you have a small list of the things they are getting wrong:

Are electric cars the future?

Are electric cars the future?

To answer the question let’s think first in the problems that electric cars have today:

Electric cars have two problems:

  1. While the current range is suitable for most people, it is not enough for everybody (to check your range just check this iPhone app).
  2. The infrastructure is not yet prepared. What happens if you don’t have a garage? What happens if you don’t have available a parking garage with available electricity outlets near to your work either? Even if the range is enough, you don’t have any way to charge your car.

Amazon EC2 vs Rackspace. Are all cloud hosting services the same?

Amazon EC2 vs Rackspace. Are all cloud hosting services the same?

About a year and a half ago we began using Amazon EC2 to host our services. Everything was perfect until the quantity of users started to grow and we started adding new services.

We've realized that the performance of the instances was decreasing fast and we needed to scale. But before starting to create a more complex architecture, we thought that it could be a good idea to take a look at Rackspace. And we were right.

Are gear boxes needed in Electric Cars?

Are gear boxes needed in Electric Cars?

We’ve got used to gear boxes. We know how to use them and some people are not able to drive a car without one. It’s like we need them. It’s part of the driving experience. But, do we really know why they exists?

Combustion engines are very inefficient. About 80% of the energy generated is transformed into heat and the other 20% goes into the real movement of the car. And part of this energy is lost in the gear box. So every time you fill the tank you must know that just a tiny bit of the fuel is really going to move the car.

1 reason for climate change skeptics to embrace renewable energy sources

Many times we have heard that renewable energy production is not cost efficient yet. Many times we have heard that the cost of a quick change to renewable energies would slow down the economy.

But how much is the cost of instability? How much will it cost the oil tomorrow? Can anybody predict it? Which energy cost are you going to consider in your business plan? How much will it cost you to fill your car’s tank next week?

What is an Electric Car simulator?

When you drive a combustion car, things are quite clear. You know that as soon as the engine starts you are consuming fuel and you know when you press the gas pedal, you consume more fuel.

Isn’t it the same in an Electric Car? Aren’t you consuming electricity from the battery all the time? The answer is no. Believe it or not, there are times when you are charging the battery while the car is moving. On the other hand, your range can change a lot according to the way you drive. Much more than with a normal car.

iPhone and Android vs Mobile carriers

I was watching the TV ads of some mobile carriers and I've realised about a common factor:

  • We are the cheapest
  • We have the coolest phones

So I've decided to go to a couple of mobile carriers shops in the area where I live to ask them how good is the signal in my house. The people in the shop were not able to tell me about the signal strength. They have no tool to check how strong the signal is in the area. But they do have cool phones. But how useful are they without signal?
