Subterranean Windfarms

Walking though the city today on the way to work I turned a corner to be buffeted by a gale blowing down the street between the office blocks. Strong wind ranks as one of my most unpleasant weather types – I’d rather have heavy rain or snow. But it occurs to me that there is an opportunity to utilise the wind blowing through our cities both in existing  and in the design of new cities.

Shell Needs Bigger Balls

I pass this advert every day on my way home from work. It’s wrong. While I’m not questioning Shell’s ability to inject 2,700 tonnes of CO2 into the Goldeneye field – I think their idea of what this looks like is more than a bit wrong.

The diameter of the ball is about the height of the Forth Rail Bridge – which is 110 m from river level to top.

The volume of a sphere is 4/3 x π x r^3 (where r is the radius of the sphere).

This gives a spherical volume of 696,910 m3 or  24,611,144 ft3

This is equivalent to about 1,300 tonnes / day. Not the  2,700 tonnes stated in the advert!

To pump 2,700 tonnes per day into Goldeneye they are definitely going to need bigger balls!

Vibrating Beer MatFive years ago I started collating my ideas and sketching them out on sticky notes. The intention was to publish them online making them prior art and making the ideas open to anyone who wanted to pursue them. I don’t’ have the time nor the energy to follow up on any of these. Most of them were silly ideas like the vibrating beer mat which has a weight sensor and a vibrating motor in it. The idea being that as a pint of lager was drunk, the weight sensor would allow the vibrator to activate and thus ‘refresh’ the head of the pint. Obviously back then I had a lot of time on my hands. Others however were of a more practical level. Continue reading Post-It Patents

Tidal Power Review

I noticed that the categories under the Technology menu included Tidal – and yet I haven’t written anything about this form of renewable energy. Indeed all seems to be quiet on the tidal front. Solar is taking off in the USA and China, while Europe is loving windpower. So who is working on tidal power today and where? A look at three on-going / upcoming tidal projects… Continue reading Tidal Power Review

US and China Pollution Pledges

Grand Canal Suzhu to Wuxi - 32 - 2006-09-10 at 08-09-46

The US and China (two of the worlds biggest polluters producing about 45% of the world’s GHG emissions have set what are believed to be ‘ambitious’ targets for cutting their emissions. Continue reading US and China Pollution Pledges

Screening CCS Projects

CO2 ChimneyI have been lucky enough (or unlucky depending on your point of view) to be involved in four separate CCS projects. Apparently this makes me a bit of an expert! Five projects actually if you count the fact that one project was a re-work of existing information for a different client (same potential store). Three of these have been shelved. I am anticipating the same to happen with the next one. Yet millions of pounds have been spent in preparing the work for a Storage Permit Application when the work required to shelve the projects took only a few weeks at a cost of perhaps £20 – £25k. Why?

CO2 Emissions Targets – 2050 and Beyond

IMG_20141011_111231Last month I attended a small presentation on Climate Change by Professor Peter Smith of Aberdeen University in the Belmont Picture House in Aberdeen. The slides from the presentation can be found here (somewhere). The presentation was well received and a good discussion followed, despite a number of cowboys making a bit of a ruckus at the back (no seriously I mean real cowboys!)

Blood is Thicker than CO2

I have to admit I’m feeling a bit guilty. I’m about to throw my carbon foot print into the next galaxy and it’s going to take a while for me to offset it.
