Intermittent

The argument put forward for nuclear as the magic CO2 bullet is that energy sources such as wind power are intermittent and would therefore need to be backed up by coal or nuclear anyway. However, research at Oxford University has produced a plan for using these supposedly unreliable generation systems. A combination of wind, micro Combined Heat and Power and solar produces an overlapping and always on set of supplies (the wind blows the most at the times of year, and even the times of day, when it's most needed and the heating's on most at the same time as light is required). Throw tidal and wave energy into the mix and you're heading for a perfect solution.

"Middle Of the Road and Off the Grid." You could call them Moogs, Wired coins the term "hygrid". Ordinary households across the US are aiming for energy independence with solar power, wind turbines and wood burning stoves. They're still connected to the power lines, because sometimes they can't produce quite enough power and sometimes they have a surplus to sell back, but their bills have plummeted.

This is energy policy I want to see my government backing. One or two Smith or Patel families in each neighbourhood slashing their energy bills by over a half would do more to speed uptake of energy saving and micro generation than any amount of woolly promises Tony could make. Once again- don't waste money trying to sell nuclear power- fund a few power stations in Acacia Avenue and see the benefits roll in.

Rotary

The Rand Cam rotary engine is lighter, more efficient and easier to maintain, with only two moving parts, the vanes and rotor, compared to 40 in a simple four cylinder engine. It also works particularly well with clean burning fuels such as hydrogen and propane.

One of the most anticipated uses for the new technology is among the blossoming hydrogen-powered automobile industry. The development of the Rand Cam(TM) engine has sparked considerable interest among environmentalists and eco-friendly manufacturers because of its ability to operate using a clean-burning hydrogen fuel cell. "Hybrid electric vehicles and engines that run using cleaner-burning fuels such as hydrogen, propane and natural gas are the future of the automotive industry," said John Robertson, CEO of Reg Technologies and its US subsidiary, REGI US. "Our society has recognized the benefits of exploring hydrogen-based technologies, and we are happy to be contributing towards the development of more sophisticated engines that operate using hydrogen and other clean burning fuels."

The long-time-coming crisis

Steven Grant has a sharp, if bleak, take on the US's prospects as far as fuel goes. It's about half way down the page.

If I appear to have no sympathy for this, it's because I don't. For a minimum of 30 years, we've known the energy crisis was the coming state of things, not just a brief blip during the Carter years.

This is also why I have no sympathy for tobacco companies or tobacco growers. There's an 1888 medical textbook that directly links tobacco to cancer, specifically lung cancer so the terminal health risks of the weed were known long before the '50s. Did tobacco companies expand into other areas and divest themselves of tobacco? No. Did tobacco farmers phase out tobacco crops in favor of other cash crops? No. If you have decades to deal with a problem, and you don't, when someone comes along and says "Take care of it right now!" do you have the right to bitch there's not enough time? Of course not.

Everybody's windmill

It's not for everyone but the Scottish Executive is pushing to have local authorities allow residents to put mini wind turbines on their roofs. Personally, I'd find these five bladed turbines a pleasant and inspiring sight, and they're practically noiseless, but there will always be NIMBYs.

Gillian Bishop, a spokesman for Views of Scotland, an umbrella organisation representing wind farm protesters, said the devices would achieve little and could be more controversial than satellite dishes.

“It seems so much effort for so little power,” she said. “They are just twiddling around the edges and I think if these things are spinning around all over the place it could drive neighbours crazy.”

New Clear

I can see, in the simplistic way that politicians have of viewing things, how nuclear power is an answer to CO2 emissions, but I can also see how it should be a long, long way down the list of things they can do. Government, and far too many activists and lobbyists, take a blinkered view of the problem. They can only think in terms of National Grid level generation. The first step toward cutting CO2 generation is making sure we use less. I don't have the figures in front of me, but I can confidently say that for the price of one nuclear power station we could install enough lagging, double glazing and low energy bulbs to save more electricity than the plant would generate. Hell, we could probably do it with the amount that's going to be wasted on the PR nightmare of selling nuclear power to the masses.

So here's my plan, if there are any politicians reading- increase the minimum insulation requirements for all new builds; give every new house a full set of low energy bulbs; offer the same for existing houses, and actually sell it rather than having it hidden in the documentary equivalent of a sullen mumble; expand the grants system for installing solar systems; and show you're committed by getting those Greenpeace blokes back on top of Prescott's palace to wire up the solar panels.

The plan will need finessing, of course, and it could be a hard sell. But think of it like this, if you can be the MP who saved householders hundreds or even thousands of pounds a year you know you're going to get re-elected. Leave the nuclear dreams to people with no imagination.

The biodiesel lorry is coming

Cambridge University has mounted a biodiesel refining plant on the back of a lorry so it can go to farms and convert rape oil to fuel at source. The portable refinery is the first in the world that can continuously produce fuel, rather than having to be emptied and cleaned after every batch.

A little bit at the end, however, has me pondering the mathematics of commercial biodiesel-

The government has made this market profitable by giving a tax rebate of 20p on every litre sold compared with commercial diesel. Tesco has begun selling a form of bio-diesel in some garages. It contains 5% bio-diesel and costs 2p a litre more than the 100% petrol version giving Tesco a substantial profit on each litre.

Unless I've read that wrong, or it's badly phrased, Tesco are taking advantage of a rebate and buyers' goodwill to gouge a profit whilst looking green. Surely they could make it a win-win by selling 5% biodiesel for a couple of pennies less and still make more per litre because of the rebate.

In a bid to solve one problem and reduce another, they are looking into using all that shit to generate heat.

Slot Cone Generator

From Norway, a country with a long and rugged coastline made up of all Slartibartfast's squiggly bits, comes a design for harnessing wave power and using it to generate a steady, rather than tide-related, flow of energy. The Slot Cone Generator is a breakwater with four slots on its face. As a wave breaks over it, the water fills reservoirs through the slot. The system doesn't generate electricity directly from the wave's energy, but from the stored kinetic energy of the water carried up to the reservoirs, releasing it over a period of hours. To further increase the flexibility of the system, it's planned to use excess electricity to create hydrogen for fuel cells etc.

I seem to remember something about buses having a great big flywheel attached to their motors that spun up to speed whilst the bus was moving and effectively stored up energy to be used when it needed to accelerate from a stop.

The pressurisation means the engine can always be running at its most efficient without losing power through a geared transmission. Carman reckons his system, currently being tested in two cars, doubles fuel economy with no other changes.

3 blades to the wind

In a way, the Navy are the obvious armed force to take to wind power. It is part of their heritage, after all. The US Navy has erected four windmills at its most controversial base.

Standing 275-foot tall, with blades spanning 177 feet, the Navy's four new 3-blade wind turbines are among the most noticeable features at Naval Station Guantanamo Bay, Cuba. Each of the four turbines will generate 950 kilowatts (kw) of electricity. Together, the four turbines will generate 3,800 kw, and in years of typical weather the wind turbines will produce almost 8 million kilowatt-hours of electricity. They will reduce the consumption of 650,000 gallons of diesel fuel, reduce air pollution by 26 tons of sulfur dioxide and 15 tons of nitrous oxide, and reduce greenhouse gas emissions by 13 million pounds each year.

46 Reasons Why

Building Green puts forward a selection of benefits to, erm, building green, for architects to pick and choose the ones relevant to a project and make selling it to the client more likely.

To those of us entrenched in the green building world the benefits seem obvious. Why would anyone choose to build in a way that isn’t comfortable, healthy, and energy efficient? In the process of designing and building green, however, we keep running into others who are not yet as convinced. For those situations, it’s useful to be able to spell out the benefits.

The building owner ultimately calls the shots, so getting that person or group on board early is essential. But not every owner will find the same arguments compelling: a hospital board may opt for green because certain green features promote healing, a commercial office property holding company may incorporate green features to speed the lease-out and thus lower carrying costs, a federal agency may desire green features to improve employee morale and increase job retention.

Even within a single project, different team members often have different reasons for promoting a green agenda. The architect may promote environmental measures because she feels it’s the right thing to do. The facilities manager who will take care of a building may recognize inherent durability and maintenance advantages. And the owner may look strictly at bottom-line financial benefits of green.

Not so much the charges and other bullshit, because I expect those from any bank, but the repetitive incompetence that's seen me in negative feedback cycles of ever increasing charges and overdraft.

Money off Ecotricity electricity is tempting, and an incentive to switch, but travel insurance deals aren't much use to me at the moment. And there's a charge, of course. Discounting the other benefits the interest rate on the account means you have to maintain a balance of over 5 grand to cover the expense of the account. If I had that much money to sit in a bank account I'd find one where it worked for me.

Nuclear Future

Honourable Fiend has a compelling take on the recent upsurge in interest in Nuclear power as "environmentalyy friendly" and a good stop gap towards the zero carbon future.

It's also extremely bad news for the commercial entities which depend on that weapons-power-weapons cycle for their bread and butter. Hence the current US fad idea of building new nuclear power stations "to reduce CO2 emissions while renewables are too expensive". Which is obviously a complete crock of shit since it's only cheaper because it's subsidized to the lug'oles, and it's only subsidized to the lug'oles because it's required to maintain a weapons programme. Plus of course there's the minor issue of waste management.

I worked at Sellafield for a while in the early nineties and there was a certain smugness that must come from being a protected industry. The biggest example of which has to be the THORP programme, which went ahead before the main customer, Japan, had signed any contracts on the understanding that if anything went wrong then the Government would surely underwrite something that had already cost X hundred million pounds rather than risk BNFL collapsing.

Hydrogen Village

One of the major complaints about wind power is that it isn't an "on demand" power source, you get electricity when the wind speed is within a certain range, which isn't always the time when the power is needed. A pilot scheme on Canada's Prince Edward Island may have the answer. It uses power from windmills to convert water to hydrogen, which can be stored and used as combustible fuel or in fuel cells. Though there are questions about the efficiency of conversion it does offer one possible solution. Possibly future wind farms could incorporate a small hydrogen power plant. When output is greater than demand hydrogen can be produced that would run the plant when output from the windmills dropped below a certain level.

Greenpeace has attacked the three main parties for leaving the environment out of their election campaigns. I heard a bit about this on Today this morning and they kept coming back to the meme that the "average voter" didn't want to hear about having to reduce their living standards in order to tackle environmental problems.

There's a simple answer to that. Don't tell them they'll have to reduce their living standards. Because they won't have to, if the issue is tackled properly. Of course, when 50% of people think that saving energy is going to cost them money- because they have a stupidly short sighted outlook and can't calculate long term savings against upfront cost, it's going to be a hard sell.

Value for Money

One complaint I heard a couple of times yesterday was that the inclusion of energy saving features in houses, whether they be new builds or refurbishments, doesn't enhance their value. It has to be time to do something about this. Other, sometimes ludicrous, "improvements" can do wonders for a house's price, so why not ones that save money?

I was looking at gas boilers and found a Powergen stand touting the WhisperGen micro Combined Heat and Power system which I've mentioned before. Take up the company's offer and you can have the CHP installed for around £3000, with a special deal whereby you sell excess electricity back to them. They estimate the system will write off the greater expense of its installation, in saved electric bills and power sold back, within 4 years. But what if you want to move out in 2 years time? You haven't fully recouped the costs and the new owner will inherit £150 a year (PowerGen's figures) in electricity savings. Surely that has to be worth something on top of all the other factors that affect a building's cost? Even after you've passed into profit the presence of such money saving tech should add to the value of your house.

Surely anything that makes a house cheaper to run, from insulation through to full energy independence, should make it more valuable. A green home that's off the grid for most of the year has to be worth more to a buyer than an equivalent sized muggle house whose occupants are being charged to damage the environment. I don't know where we go to increase the value of green choices, but I say we start here.

Volkswagen have halted development of a super efficient vehicle. The two seater had a 300cc diesel engine and super light frame and could manage 60 miles per litre. However it lacked luggage space and was going to be too expensive to produce. It's sort of a loss and not a loss. VW are still producing the Lupo TDI, which does 20 miles per litre. Combine that with biodiesel and you could be onto a winner.

You are what you throw away

Around a third of all food in the UK is thrown away. The process starts with the need for perfect, symmetrical and clean groceries and continues all the way through the process to failure to reuse left overs and throwing out stuff that's a second past its sell by date. I couldn't calculate it, but I'd hazard a guess that Casa Spinneyhead's cost per capita in food waste is less than the national average of £420 per year, especially now we've started composting. (A matter for another time is just what the hell am I going to do with the compost when it matures? It's not like we have a garden or anything.)

Six of one, half a dozen the other

With Chloroflourocarbons phased out the ozone layer may be safer, but the replacement chemicals are proving to be greenhouse gases.

"Initially, it was thought these were an ideal solution -- obviously that was not the case if they were contributing to another problem."

While CFCs contribute more per unit to global warming, the rapid increase in the use of replacement chemicals makes them now the greater threat to climate stability, Metz told the AP in a telephone interview.

Big Bang at the ballot box

Call me a cynic, but Tony Blair's hinted renewal of support for the Metrolink smacks of electioneering to me. I'd like to see trams running in the south of Manchester but for the next few weeks I'm going to be even less inclined than normal to believe a word the PM says.

It's a guilty pleasure, but I do enjoy Top Gear. I disagree with Clarkson on just about everything, but he is eternally watchable, and the Little Man is a Casa Spinneyhead favourite. I wouldn't go as far as Transport 2000 and say the programme should be scrapped completely, but there definitely should be a Two Wheels Good or How To Save The World For Free (two programmes I'd like to pitch) as balance.

It's all well and good going over to biodiesel as a way to free yourself from the oil industry, but you're still burning fuel and pumping something out the back. Is it actually any cleaner?

Not through my bars

A different take to wind power's NIMBY problem. The company running a windmill close to Whitemoor jail have agreed to turn it off early in the morning because flickering shadows from the spinning blades were aggravating prisoners.

Whitemoor contains prisoners it is best not to upset, including road rage killer Kenneth Noye, Jeremy Bamber who murdered his family, and Barry George, who killed television presenter Jill Dando.

Auf Wiedersehn, Pet?

A robotic wall laying machine could dramatically change the way buildings are erected. From an eco point of view, the materials used can be changed and complex shapes formed- if the solar ventilation for a pbuilding requires complex ducting the robo-builder can do it from CAD designs- and labour savings can bring the prices down.

Khoshnevis is inspired by the technology’s potential to build dignified low-income housing. “A billion people today do not have adequate shelter,” he says. Using soil dug from the building site and stabilized with cement, the contour crafter could erect inexpensive dwellings customized to a family’s needs.

Smarter than Smart

The G-Wiz promises to be the greenest car to run in the UK. Charge it up overnight for daily running costs as low as £1.64. You don't even need to worry that the electricity used is unsound, the company promises to carbon balance the production, shipping and first 16,000 miles of running. Whilst being carbon neutral in your daily transport you can campaign for more green electricity to charge it in its twilight years.

I might even forgive the school run if this is what the mums were turning up in.

Compost

Casa Spinneyhead still throws away a lot of perfectly good composting material, so I'm looking at ways to utilise it.

Hippyshopper recommends wormeries, but I'm working on a budget. Recyclemore.co.uk has cheaper options. The Community Composting Network has resources if I wanted to get my neighbours to muck in. Allegedly the council has a scheme where I can get cheap compost boxes, but the number on the website has been disconnected, so that's not much use. They do run the Kerb it green waste recycling service, but we're obviously not in any of the chosen pilot areas.

To conclude- it's off to B&Q I go!

UpdateJeff pointed me to this easy DIY wormery, and I found the Green Cone, designed to speed up the composting through solar heating and insulation and feed the nutrients direct into your soil.

Toward the Carnot limit

The Carnot Limit is the maximum efficiency possible for a heat engine. Until now thermoelectric devices have only had an efficiency of 15% of the Carnot limit. However, research with nanostructured materials will allow a new generation of thermoelectric devices to operate nearer to the limit, opening up a whole range potential uses from silent computer cooling to geothermal power.

Waterworld

CLIMSystems of New Zealand have released SimCLIM, a program that will simulate sea level changes at various scales. From the press release-

CLIMsystems Ltd., Hamilton, New Zealand (PRWEB) April 7, 2005 -- A new software package has just been released on the World Wide Web that enables coastal zone managers, coastal zone property owners and any other people or organisations interested in coastal zone issues to create scenarios of future sea-level change at global, regional and local scales. The SimCLIM Sea-Level Scenario Generator software, found at http://www.climsystems.com/site/home/, provides an easy-to-navigate windows platform for creating a wide range of sea-level change scenarios using the latest scientific knowledge. The software is unique as it is the first of its type to provide users with the capacity to create scenarios of future sea-level anywhere in the world that take into account global, regional and local components of change.

I'm going to use it to see what conditions would result in a beach on my doorstep, but it will have serioususes for coastal inhabitants and the people who manage our coastlines.

Recar

Lots of current cars are built to be recycled, but what about older vehicles? After being crushed the larger chunks of metal can be re-used, but that leaves a sludge of smaller parts that can leach toxins into landfills.

CSIRO Minerals are developing methods to clean this sludge up and get the maximum value from it by using mineral processing techniques. At present it's a low margin operation but any number of factors, from rising material costs to more stringent landfill controls, could make it a money spinner.

Green State

Washington state now has a law requiring that new municipal buildings incorporate energy saving and "green" technologies. It costs more up front, but the long term savings more than cover it. The law's supporters also promised a better environment for those who work and study there, which is probably true, but a lot harder to argue in any concrete way.
