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.
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!
Five 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
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
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
I 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?
