Wave Energy for Desalination

CETO Wave Energy has designed a system that uses tidal power to both pump water and desalinate it! Desalination is a growing necessity in areas lacking fresh water that have access to sea water; however, it is energy and cost intensive. By using a renewable resource, it makes desalination a viable option.

Unlike other wave energy systems currently under development around the world, the CETO wave power converter is the first unit to be fully-submerged and to produce high pressure seawater from the power of waves.
By delivering high pressure seawater ashore, the technology allows either zero-emission electricity to be produced (similar to hydroelectricity) or zero-emission freshwater (utilising standard reverse osmosis desalination technology). It also means that there is no need for undersea grids or high voltage transmission nor costly marine qualified plants.

Blimps for Heavy Lifting

Airships are really fun! We haven’t looked at them in a long time though, last time airships were mentioned here was in 2006. Well, there has been some development since then and now a company has designed an airship for really heavy lifting.

SkyHook International announced Tuesday that it will build the Jess Heavy Lifter (JHL-40) in conjunction with aircraft manufacturer Boeing Co.

The JHL-40 takes elements of a blimp and a helicopter to lift up to 40 tonnes in one load and travel up to 320 kilometres without refuelling. It will have a top speed of 70 knots.

“The perception is ‘Oh, it’s going to blow up. It’s a Hindenburg or something like that.’ And it’s going to be our job to educate people as to what this thing is. You can’t get around the fact it’s a large envelope full of helium, and it does look a little bit like a balloon,” said the aviation engineer and former helicopter pilot.

“It’s a blimp on steroids because it’s got more than 20,000 horsepower on it and it’s a serious working machine.”

The company said that unlike blimps, the airship is neutrally buoyant.

Ontario and Quebec Don’t Like Carbon

I’m not a big fan of carbon trading but there is good news insofar that two Canadian provinces, Ontario and Quebec have decided to tackle environmental concerns. The Canadian federal government has followed the lead of Bush’s administration and have tried to stop any environmental progress, indeed they even say Ontario and Quebec are wrong because they are doing something. I sure this is the first of many headlines that show the provinces leading the environmental way in Canada.

It’s great to see two large provinces in Canada teaming up to show the federal government that they are open to legislating improved environmental protection.

Charest called tackling the issue of climate change a “tremendous challenge for humanity.”

He said whoever becomes the next U.S. president will be doing a “180-degree turn” on climate change policy, and the two provinces shouldn’t wait for that to happen before making changes of their own.

“Why wait for the Americans? We want to subscribe to everything that is being done on the European level and the North American level,” Charest told reporter

Eco-Flooring

flooring

There are a few options on how to make that thing you walk on everyday a little more environmentally friendly. Bamboo flooring is my personal favourite. Some enterprising people have taken left over flooring from other projects and put them together in a neat way.

In keeping with our eco design model, and just for the sheer fun of it, we’ve decided that the kitchen floor will be made up from all the leftover pieces of Marmoleum we’ve saved so far.

The first part was the installation of a high quality sub-floor (similar to the bathrooms), consisting of maple plywood and a lot of staples.

SMS Helps Rural Farmers

Cell phones are handy devices and can be used for seemingly endless purposes. Indian farmers are using SMS to help them earn more money from their crops.

Standing in a grove of lush green banana trees I find Kapil Jachak.
He’s busy checking his mobile phone for text messages containing practical information for farmers.
It’s a new service called Reuters Market Light, and he was one of the first to sign up in this area.
The first message every morning is a daily weather forecast for his area.
“By getting the weather reports we can see exactly how much water our banana plants need,” he says, “I keep my cost down, and get the best crop I can.”
