jim s 34 Posted July 22, 2021 Share Posted July 22, 2021 managed to dig a few pics out....Possibly the best day i've had exploring on the bike. i recall a few months after we were there they had something like 450mm rain in a day and the road in was wiped out for the medium/long term.. 2 Quote Link to post Share on other sites

twisty 176 Posted July 23, 2021 Share Posted July 23, 2021 Another Bikie here. I raced an H2 and a Z1 in the late 70's. Wasn't very good ! Now riding a Multistrada as I can't ride sports bikes anymore (999 was my last) I think riding a bike around a corner well is the same feeling you get sailing a boat on the wind when you've managed to get it in the groove. 2 2 Quote Link to post Share on other sites
erice 732 Posted July 23, 2021 Share Posted July 23, 2021 heard a dunedin? scientist on the radio this morning saying the huge green-hydrogen plant at tiwai just isn't going to happen apparently the science experiment they would like to scale up would require A LOT of platinum not a metal in great supply... Fast forward five years and gold now is more than double the price of platinum, even as platinum is considered to be 30 times rarer than gold, and more expensive to mine, Caruso said. https://www.marketwatch.com/story/green-hydrogen-is-opening-doors-for-higher-platinum-demand-11605902071 might be time to swap my hoarded toilet rolls for platinum 1 Quote Link to post Share on other sites
El Toro 97 Posted July 25, 2021 Share Posted July 25, 2021 There are some seriously big hitters trying to get Tiwai off the ground with green hydrogen. Thats not to say it will happen, but some people with extremely deep pockets are def having a good gander at it. if its possible to pull it off, Im all for it. Remove the sludge then export 'free' power and keep all the jobs, or words to that effect. Quote Link to post Share on other sites
erice 732 Posted July 25, 2021 Share Posted July 25, 2021 i seem to remember muldoon's "think big" motunui methanol plant took natural gas that could run a car 500?km and turned it into synthetic petrol that would run a car 200?km (rather than turn that science project into a factory it would have been better/cheaper to simply give nz'ers free cng/lpg conversions for their cars) https://teara.govt.nz/en/photograph/8935/motunui-synthetic-petrol-plant https://teara.govt.nz/en/oil-and-gas/page-5 Efficiency[edit] In 2013, the round-trip efficiency of power-to-gas-storage was well below 50%, with the hydrogen path being able to reach a maximum efficiency of ~ 43% and methane of ~ 39% by using combined-cycle powerplants. https://en.wikipedia.org/wiki/Power-to-gas the loss back then was supposed to be worthwhile because we already had cars that ran on petrol and a petrol network ... seems to me tiwai risks taking electricity that would run a car 500km and turning it into hydrogen to run a car 200km and we don't yet have cars with fuel cells (far more complex than attaching a simple cng/lng conversion or a hydrogen network (vastly more complex and difficult to store than cng/lpg......hydrogen boiling point -253C) https://www.energy.gov/eere/fuelcells/hydrogen-storage-basics-0 https://energy.nl/en/fact_sheet/liquefied-hydrogen-storage/ it will be interesting to see how it all pans out Quote Link to post Share on other sites

It could be (and I'm happy to be corrected) that the losses in conversion are acceptable when measured against the cost of getting the generation plant hooked into the network including transmission line upgrades, synchronisation etc Quote Link to post Share on other sites

See grid map below. https://www.transpower.co.nz/sites/default/files/bulk-upload/documents/Substation Locator map.pdf The only issues associated with an exit of Tiwai are the lines (generally) heading to Benmore and the HVDC link. The initial work to address the issue to Benmore are either completed or underway. Quote Link to post Share on other sites
ballystick 72 Posted July 26, 2021 Share Posted July 26, 2021 I spent around 12 years racing off road, mx and hare scrambles. I mainly rode Suzukis and sometimes got a chance to ride Greg Brinck's (NZ no.1 at the time) RM400 that had been fully worked by the legendary Dick Lawton from Lawton & Boyle (Wgtn) 3 Quote Link to post Share on other sites
