Wind Fins: Novel Lower-Cost Wind Power System
This project evaluated the technical feasibility of converting energy from the wind with a novel “wind fin” approach. This patent-pending technology has three major components: (1) a mast, (2) a vertical, hinged wind structure or fin, and (3) a power takeoff system. The wing structure responds to the wind with an oscillating motion, generating power. The overall project goal was to determine the basic technical feasibility of the wind fin technology. Specific objectives were the following: (1) to determine the wind energy-conversion performance of the wind fin and the degree to which its performance could be enhanced through basic design improvements; (2) to determine how best to design the wind fin system to survive extreme winds; (3) to determine the cost-effectiveness of the best wind fin designs compared to state-of-the-art wind turbines; and (4) to develop conclusions about the overall technical feasibility of the wind fin system. Project work involved extensive computer modeling, wind-tunnel testing with small models, and testing of bench-scale models in a wind tunnel and outdoors in the wind. This project determined that the wind fin approach is technically feasible and likely to be commercially viable. Project results suggest that this new technology has the potential to harvest wind energy at approximately half the system cost of wind turbines in the 10kW range. Overall, the project demonstrated that the wind fin technology has the potential to increase the economic viability of small wind-power generation. In addition, it has the potential to eliminate lethality to birds and bats, overcome public objections to the aesthetics of wind-power machines, and significantly expand wind-power’s contribution to the national energy supply
Imperialisms Past and Present in EU Economic Relations with North Africa
The EU is actively pursuing Deep and Comprehensive Free Trade Agreements (DCFTAs) as part of its trade and aid relations with former colonies in North Africa. Utilizing the discourse of pro-poor business growth and win-win free trade, the EU insists that North African countries must acquiesce to DCFTA liberalization to achieve sustainable development. This article critiques the paternalism of EU actors amidst their focus on completing these controversial DCFTAs. Drawing upon Nkrumah's and Fanon's articulation of the concept of neocolonialism, it argues that the EU is cementing colonial-style patterns of production via iniquitous trade and aid arrangements. Moreover, the article illustrates that EU elites in their justification of the DCFTAs are replicating the colonial-era discourse surrounding Eurafrica and the alleged economic “complementarity” and inevitable “interdependence” of the European and African continents: an amnesiac Europe thus simultaneously draws upon European colonial imaginaries in the justification of neocolonial DCFTAs while downplaying, and forgetting, the regressive legacies of colonial trade relations. The article also demonstrates how certain North African campaigners are already drawing attention to the neocolonial contours of the DCFTAs in order to delegitimise these free trade vehicles vis-à -vis North African and European public opinion
