Big Green

Some of Britain's leading industrialists are calling on the Government to give their industries concrete targets for reducing CO2 emmissions.

The letter has been arranged through the Prince of Wales Business and Environment programme. The business leaders say they are very concerned about the prospect of dangerous climate change and support the government's target of reducing CO2 emissions by 60% by 2050.

They regret that industry and government are currently caught in a Catch 22. Governments are nervous of clamping down on climate change emissions for fear of a backlash from business.

But I want that one....

Moral dilemma time. Yesterday I was working out what I wanted from my next mobile phone (fewer minutes- I'm currently only using 40 of the 200 free minutes I pay for every month- better data rates and lots of cheap texts). Secondary in importance was which phone I wanted to do all these things with. Sadly, according to ethiscore, SonyEricsson, whose products I've liked since having a 6210, come out second from bottom in the ratings. Sharp, the maker of my current phone, come in joint second, but I'm less than impressed with the software that comes with it and my preferred supplier doesn't issue them anyway. Sagem is also joint second, but their phones are shit

I guess there's always Nokia.

Rules of the road

A woman's guide to cycling.

Local governments tell feeble lies

All local councils claim to want to encourage cycling. They read in a book somewhere that this is what you ought to say once you ascend into local office, like, "I've lived in this community all my life, and have a real commitment to the area." To this end, they put out measly leaflets telling you pig-obvious things like, "Avoid getting trapped between two articulated lorries." If you didn't know that, you'd already be dead.

The truth is, they hate cyclists with a passion. That's the only way you can possibly explain all the things they do to endanger us, like inventing giant buses that bend in the middle, and laughingly encouraging us on to cycle paths so badly maintained they look like a trap set by Wile E Coyote. When you hear anything from any official on this matter, never forget they lie. They lie, they lie, they lie. It's even possible that Steven Norris is lying about the helmets.

The kind of person who routinely prefixes "cyclist" with "kamikaze" is exactly the kind of person who prefixes "asylum seeker" with "bogus"

Nappy ever after

Leo Hickman, who has practical experience of nappies having spent a year "elbow deep in excrement" picks apart yesterday's report about disposable nappies.

The fact is that, to my eyes at least, this report is full of holes. Why are its findings based on an assumption that washable aficionados use 47 nappies, whereas we had easily got by on 20? Why did the Environment Agency survey 2,000 parents using disposable nappies compared with just 117 using washables, meaning that (taking into account the weighting towards those using older-style nappies which use more cloth), many of the assumptions are based on the habits of just 32 people? Why does the report include the energy used to iron nappies? Who on earth irons their nappies? Why was it assumed that people environmentally conscious enough to be using washable nappies would automatically want to tumble dry them?

Two birds with one coconut

Tablas Island is one of the poorest parts of the Phillipines. It also has the highest harvest of coconuts. So a newly opened biodiesel plant that makes fuel from the coconuts serves two purposes- fuel independence and a cash crop from over production.

"We deliberately chose Romblon because it is an island province and it is coconut-producing. This being an island economy, diesel prices in the region are higher because of cost of transporting the fuel so it makes sense that the province look for an alternative fuel using the raw materials available, which is copra," [DOST Secretary Estrella] Alabastro said.

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.

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.

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.

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.

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. A much more elegant and efficient system has been developed by Vincent Carman. It uses hydraulic pressure to store up energy and transfer it to the wheels. 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.
