| 450705 | 2006-05-01 03:39:00 | New Zealand doesn't have any really big turbine sets. The biggest is Otahuhu with 380MW generation capacity. Had forgotten about hydro plants sending the water back uphill. Excellent idea. Perpetual motion?? :waughh: |

| 450707 | 2006-05-01 04:06:00 | There are a number of pumped storage schemes around, Cruachan was the first I think. www.esru.strath.ac.uk There are two English Electric sets and two AEI. In those days CEGB always shared the work around more or less evenly between the major power generation firms. Both sets had early problems of the turbines lifting off the single sided thrust bearings when in pumping mode. Our job was to install remote monitored displacement transducers for both the journal and thrust bearings, and to analyse the lifting problems. New Zealand should be looking at the feasibility of this kind of technology for storing wind power, as well as for base load purposes. That is a sort of "co-generation" wind/water power. Edit sorry had wrong link |

| 450710 | 2006-05-01 10:24:00 | I was under the impression that to create antimatter it requires vast mounts of energy? Er . . . . . yes . Details details . :D And the energy from the reaction is incredibly hard to harness? No problem . Use magnetic traps . But holding it for long is the difficulty .

| 450714 | 2006-05-01 22:41:00 | The fashion for wind farms puzzles me . Water has magnitudes more mass than air and can be controlled to give constant reliable flow . Think of a bucket of air compared with a bucket of water - the air will spin a small turbine for a few seconds but the water will spin it for a minute . Technology is part of the problem but I really think Meridian et al should be concentrating on water . Perhaps the Green lobby has captured business and political thinking so that wind turbines are now sexy . :waughh: Water - turbines can be placed in rivers without a dam, tidal flows can be trapped by a weir for generation, wave motion generators, venturi (a water/wind hybrid) generation, thermocline - the list goes on . Certainly some of these technologies are in their early stages but NZ has water everywhere, particularly the ocean . |
