'Energy Recovery from Waste'

Charles Lee
Presentation given at iWater 2012
iWater & Waste-as-Resource Conference
Murray Edwards College, Cambridge
13 November 2012

This talk considered options for energy recovery from waste material in closed loop supply chains. It outlined different approaches to recovering energy from waste (incineration, Mechanical Biological Treatment (MBT), Anaerobic Digestion (AD), landfill gas, biodiesel, straw-to-electricity and logs-to-heat) and discussed some of the issues raised.

'Five questions a cleantech start-up founder needs to ask'

Charles Lee
Presentation given at Innovation in Clean Tech - Technology and Innovation Forum
Hethel Engineering Centre, Hethel, Norwich
25 October 2012

Charles presented five questions that a cleantech start-up founder needs to consider, and used these to raise some essential issues of investing in cleantech businesses.


'Tidal stream energy: the ‘Sea-Spider’ vertical axis tidal turbine'

Evening lecture organised by the Institution of Mechanical Engineers

Tidal energy has the attraction over wind and wave energy that although it is intermittent it is wholly predictable. Tidal stream devices can be located under or near the surface of the sea, minimising visual and environmental impact.

Most of the tidal turbines currently being developed today are axial flow propeller turbines, mounted on structures positioned on the seabed. As the generators and many working parts are submerged, divers, crane barges or lifting structures are needed to raise them to the surface for maintenance, which is costly. Devices have so far been developed up to about 1MW, and the approach being taken to scale up further is to build arrays of turbines.

Sea-Spider is a novel vertical axis tidal turbine developed by Renewergen Ltd. Sea-Spider’s design places all electrical generating plant above the water, allowing easier and safer access, and lower operation and maintenance costs. It is designed to be scaleable to a large size, enabling economic deployment in a wide range of locations.

A nine month research project, partly funded by EEDA and the ERDF, explored the technical and economic feasibility of the concept. This included testing of a working model, development of computer simulations, input from specialist sub-contractors with experience of offshore energy, and an independent due diligence review. A patent has been published. Partners are being sought to finance further development of Sea-Spider.

In the first in-depth talk given on the project, the speakers discussed the advantages and challenges of tidal stream energy; the approaches being taken; examples of some devices that have been deployed; the features and advantages Sea-Spider; its development to date and lessons learnt.

The speakers were Simon Sanderson, the inventor of Sea-Spider; and Charles Lee, who supported the engineering of the project.

'The Future of Mobility'

Charles Lee
Evening lecture organised by the Institution of Mechanical Engineers
Department of Engineering, University of Cambridge
21 September 2009

How will we travel and transport goods in the 21st Century?

What will we do when the oil runs out? Are biofuels, hydrogen or battery electric vehicles the answer? Will we still fly? What will power ships? How will we plough fields to feed the world's population? How will our lives be different?

Mobility in the future will depend on harnessing sustainable sources of concentrated energy.

Taking a long-term view, Charles presented a wide-ranging review of the options and proposed some thought provoking solutions.

'Closed Loops for Sustainability and Profit'

Charles Lee
Presentation given at EAME08
The Second Annual Exhibition of Advanced Manufacturing and Engineering, EAME08
Sustainability Conference (Real Advice Forum)
Hethel Engineering Centre, Hethel, Norwich
17 September 2008

Supply chains are traditionally viewed as ‘open loop’. However, resources are finite, and in the long term, this is not sustainable. By considering material flows within manufacturing processes and within the supply chain, businesses can identify opportunities to conserve resources and increase profits through the introduction of Closed Loops within processes, in the supply chain and by post-consumer recycling. There are alternative service models that support this. While there are many solutions, no one approach fits all cases, but organisations can be systematic in seeking opportunities.
