http://www.hydrocoop.org/tidal-energy-new-solution-may-double-worldwide-potential/ A New Solution May Double The Worldwide Potential of Tidal Energy and Half Its Cost - A new specific solution better adapted to the specific tidal energy is presented in this article; it may apply to 1 500 TWh/year at a cost close to the hydropower cost, and with a better environmental impact.

http://www.hydrocoop.org/piano-keys-weirs-could-be-used-for-most-african-spillways/ Piano Keys Weirs (PK Weirs) Could Be Used For Most African Spillways - For cost or safety reasons the fully gated spillways will probably be avoided for most future dams and free flow spillways will likely be the most used solution.

http://www.hydrocoop.org/concrete-fuse-plugs/ Concrete Fuse Plugs - Dam & Spillway Design - Concrete fuse plugs are simple massive blocks placed side by side on a spillway sill. They are free standing and stable until the water level in the reservoir reaches a certain elevation and they start tilting when this elevation is exceeded.

http://www.hydrocoop.org/increasing-fivefold-discharge-capacity-free-flow-spillways/ Increasing fivefold the discharge capacity of free-flow spillways - The drawback of traditional free flow spillways is their low specific discharge. C.I.S. (Combining Innovative Spillways) may increase fivefold the discharge at low cost. Two spillways may be associated: PK- Weirs and Concrete Fuse Plugs.

http://www.hydrocoop.org/new-tidal-energy-solutions/ New Tidal Energy solutions (Q.96 ICOLD 25th Congress - Stavanger) - Most past designs of tidal plants have been devoted to best sites of few countries. However the proposed solutions appear usually too expensive in the very specific conditions of tidal energy.

http://www.hydrocoop.org/new-promising-solutions-for-tidal-energy/ New promising solutions for Tidal Energy (26th ICOLD Congress - Q.96) - Hydropower and Tidal Energy have about the same theoretical potential, above 20 000 TWh/year. The possible energy supply per km2 of tidal basin (20 GWh/km2 with a tidal range of 5 m) is higher than the average energy supply per km2 of dam reservoirs (3 500 TWh for 350 000 km2, i.e. 10GWh/km2).

http://www.hydrocoop.org/piano-key-weirs-pk-weirs-triple-the-spillways-discharge/ Piano Key Weirs (PK Weirs) triple the spillways discharge - Tested since 15 years and implemented on many dams in various countries since 10 years, the Piano Key Weir, an improved labyrinth design, appears very cost efficient, optimizing hydraulic efficiency as well as structural requirements and construction facility.

Mom of two - Wonderful Product

I bought this when I saw that Vitamin C was the best thing for your face. It came with 2 and I have started my second one and so far so good. I loved the sun when I was younger and it really seems to be helping fade the sun spots on my face. I use it every night on my neck and face. Will be buying again when I need to.

Katy - LOVE IT

This mask is awesome!!! It leaves your hear feeling like silk! The texture is so reach it almost feels like a lotion. When you put this mask on, it will stay on, no leaks! I don't like messy products and this is definitely not one of them! The packaging is awesome because each pouch it's packaged individually with hair covers in each one of them. This way the product stays fresh and you can bring it with you while travelling. I couldn't be happier about this mask, this is exactly what I needed to revitalize my dried and thinning locks. I'm very happy with this mask and will continue to use it monthly. I've been using Pura D'Or shampoo for a while and this is another great product from them.

Ismael Gonzalez - Giant leap for the entertainment of human kind

This is just beyond "gaming"as we call it, new Era in entertainment for us all, incredible gadget, I absolutely love it... little advice, make sure you have extra hdmi cables, the ones provided by sony, are not good as usual...

Dephtones - Great machine if you get it for the right price

I was looking to build a PC to have in my living room. I built a very high end one for my man cave and wanted one for the living room just to have another PC in the house for browsing and gaming but didn't want or need a killer thousand dollar rig. I found this on clearance at Walmart for 299 and immediately bought it. I bought 8gb of ram on Amazon for 20 bucks, and a 7200 rpm external drive 1tb. I had a 250gb m2 ssd that I previously bought for a laptop and it was collecting dust. Luckily I still had it. I bought an enclosure on Amazon that turns it into a regular size ssd.

Dexter Cannon - Better Hurry!

These hands of mine must be the worst. It doesn't seem to last long; like a few minutes. Purchased to help with sweaty hands while playing basketball. I put it on, let it dry (white), and seems like only minutes later there is no trace of ever applying it. So, I guess I'll just blame my hands.
