Note on the History of the Innominata Face of Mont Blanc De Courmayeur
1 34 HISTORY OF THE INNOMINATA FACE them difficult but solved the problem by the most exposed, airy and exhilarating ice-climb I ever did. I reckon sixteen essentially different ways to Mont Blanc. I wish I had done them all ! NOTE ON THE ILLUSTRATIONS FIG. 1. This was taken from the inner end of Col Eccles in 1921 during the ascent of Mont Blanc by Eccles' route. Pie Eccles is seen high on the right, and the top of the Aiguille Noite de Peteret just shows over the left flank of the Pie. FIG. 2. This was taken from the lnnominata face in 1919 during a halt at 13.30 on the crest of the branch rib. The skyline shows the Aiguille Blanche de Peteret on the extreme left (a snow cap), with Punta Gugliermina at the right end of what appears to be a level summit ridge but really descends steeply. On the right of the deep gap is the Aiguille Noire de Peteret with the middle section of the Fresney glacier below it. The snow-sprinkled rock mass in the right lower corner is Pie Eccles a bird's eye view. FIG. 3. This was taken at the same time as Fig. 2, with which it joins. Pie Eccles is again seen, in the left lower corner. To the right of it, in the middle of the view, is a n ear part of the branch rib, and above that is seen a bird's view of the Punta lnnominata with the Aiguille Joseph Croux further off to the left. -
Hydrogen Storage for Mobility: a Review
materials Review Hydrogen Storage for Mobility: A Review Etienne Rivard * , Michel Trudeau and Karim Zaghib * Centre of Excellence in Transportation Electrification and Energy Storage, Hydro-Quebec, 1806, boul. Lionel-Boulet, Varennes J3X 1S1, Canada; [email protected] * Correspondence: [email protected] (E.R.); [email protected] (K.Z.) Received: 18 April 2019; Accepted: 11 June 2019; Published: 19 June 2019 Abstract: Numerous reviews on hydrogen storage have previously been published. However, most of these reviews deal either exclusively with storage materials or the global hydrogen economy. This paper presents a review of hydrogen storage systems that are relevant for mobility applications. The ideal storage medium should allow high volumetric and gravimetric energy densities, quick uptake and release of fuel, operation at room temperatures and atmospheric pressure, safe use, and balanced cost-effectiveness. All current hydrogen storage technologies have significant drawbacks, including complex thermal management systems, boil-off, poor efficiency, expensive catalysts, stability issues, slow response rates, high operating pressures, low energy densities, and risks of violent and uncontrolled spontaneous reactions. While not perfect, the current leading industry standard of compressed hydrogen offers a functional solution and demonstrates a storage option for mobility compared to other technologies. Keywords: hydrogen mobility; hydrogen storage; storage systems assessment; Kubas-type hydrogen storage; hydrogen economy 1. Introduction According to the Intergovernmental Panel on Climate Change (IPCC), it is almost certain that the unusually fast global warming is a direct result of human activity [1]. The resulting climate change is linked to significant environmental impacts that are connected to the disappearance of animal species [2,3], decreased agricultural yield [4–6], increasingly frequent extreme weather events [7,8], human migration [9–11], and conflicts [12–14]. -

It is demonstrated that perforation of graphene sheets results in increase of theoretically possible surface areas beyond the limits of ideal defect-free graphene (~2700 m2/g) with the values approaching ~5000 m2/g. This in turn implies promising hydrogen storage capacities up to 6.5 wt% at 77 K, estimated from classical Grand canonical Monte Carlo simulations. -

Accidents, 1949 245
ACCIDENTS, 1949 245 • • ACCIDENTS, 1949 THE climbing season of I949 was notable for fine weather and dry con ditions similar to those of I 94 7. Snow disappeared from rock faces which, like the final cone of the Hasli Jungfrau peak of the Wetterhorn, are very rarely exposed ; the glaciers showed bare ice even up to the level of Io,ooo ft. in some cases ; they were greatly crevassed, and so shrunken that it was often difficult to gain the flanks above their edges ; mountain faces and aretes were unusually free of snow~ arid the exposure of rotten tock caused innumerable stonefalls. The fine weather, the many new or enlarged huts, and the facilitation of the approaches by marked paths or even by cable lifts, attracted cro,vds of inexperienced tourists to the higher mountains, but it was noticeable that the propor tion of serious climbers was small. In these circumstances, the heavy death-roll which we have to lament was to be expected. The greatest ultimate cause of the fatal accidents was undoubtedly inexperience ; the most common immediate cause seems to have been stonefall ; but there were many instances of pure ' accident,' such as the disaster at Cham onix when the collapse of the lower part of the Tour glacier cost the lives of a number of innocent visitors. Another remarkable disaster was that caused by an unexpected storm on Mont Blanc on August I 1 ; and at the other extreme of chance, there were many curious causes of fatality, as in the case of a climber who unroped on the Dome de Roche fort and lost his balance whilst changing his shirt. -
Aiguille De Rochefort 4001M
Aiguille de Rochefort 4001m The Aiguille de Rochefort is a 4001 m high mountain situated in the middle of the long ridge that goes from Dent du Geant to the Grandes Jorasses. The snow ridge that goes to this peak is among some of the most famous and aestetichs route of the Alps. It's one of the best and recommended day tours in the Mont Blanc area. Program: 1st day: meeting with the guide at the Mont Blanc lift station at 7:00 o'clock. After the equipment-check we take the lift up to Rif. Torino station. Few steps and we are on the glacier.The first part, until the “Gengiva” is quite easy scrambling. From there we start to follow the narrow snow ridge that with few up and down goes at the bottom of the last difficult cliff. 3 pitches on solid granit and we are on top of the Aiguille de Rochefort. The way back is along the same itinerary; with 3 rappels we pass the rock cliff and then we follow the ridge back to the “Gengiva”. Following the same itinerary of the way up, we go back to Rif. Torino 4 to 5 hours 700m 3 hours 700 m You have to know: Accommodation: Hotel in Courmayeur Meeting point: At 7:00am at the lift station in Courmayeur. Requirements: Steep and mixed terrain, rock climbing up to grade III° and confidence with abseiling technique. Some previous experience in mountaineering is required. Weather: In the high mountains, even in summer, there could be extreme weather conditions. -
