Osmotic power membranes coiled up inside pressure vessels

Starting tomorrow, the world’s first power plant generating power from salt water will be opened at Tofte in Norway. Back in May, I did a little roundup of various ways to get power from water. One of the more experimental technologies I mentioned was salt power – or osmotic power, which is the more precise [...]

Time to grow some backbone: Oil reserves grossly misreported

The earth, soiled by oil from an oil barrel

A few weeks ago, I argued that it doesn’t matter whether climate change is manmade or not. This article in the Guardian only reinforced that view. A whistleblower employee of the International Energy Agency (IEA) is saying that his employer is knowingly exaggerating the size of the world’s total oil reserves, to avoid “angering the [...]

Greener energy production: Run your dishwasher at night

by thomas on May 22, 2009

You can help reduce the needed energy production from dirty coal and other non-renewable resources – just by running your dishwasher and other appliances at night. The demand for electricity is higher in the daytime than at night, particularly during office hours. The increase in demand starts in the morning when people and businesses switch [...]

Water power and the ways it can be used

by thomas on May 6, 2009

Following up my roundup of renewable energy sources, it’s now time for a look at water power (also called hydropower and hydraulic power) and its main uses. Please note: Although tidal power and wave power are also forms of water power, I think they’re interesting enough to merit their own posts later. In this post, [...]

NIF scientists aim for fusion power

by thomas on May 5, 2009

Wired has a fascinating article today: Using 192 separate lasers and a 400-foot-long series of amplifiers and filters, scientists at Lawrence Livermore’s National Ignition Facility (NIF) hope to create a self-sustaining fusion reaction like the ones in the sun or the explosion of a nuclear bomb – only on a much smaller scale. In doing [...]

Solar energy and the ways it can be used

by thomas on April 28, 2009

Last week, in my roundup of renewable energy sources, I promised to give each source a closer look in future posts. Let’s start off with the Sun and its abundance of solar energy. As noted in my previous roundup, the Sun radiates almost inconceivable amounts of energy in our direction. If we could utilize even [...]

Renewable energy sources: What types are there?

by thomas on April 21, 2009

There are many sources of environmentally friendly, renewable energy. This post is a brief roundup covering most of them. I’ll cover each one and their general uses in more detail in other posts, linking to them from this post in the process. Feel free to leave a comment if you think I forgot one! The [...]
