It’s Time To Howl, Baby : The Lunacycle 30Q Wolf Pack

If you don’t care about stealth, the ‘naked’ wolf pack is the way to go, it’s a thing of true beauty Eric from Lunacycle has a great scam going. He sends me new products for testing on his dime, I beat on them for a few months then eventually fall in love with whatever he sends me and end up buying it. I was skeptical about how I would feel about the new Wolfpack he had been designing for many months, but after 3 months of hard abuse, this frame pack has taken everything I’ve thrown at it without breaking a sweat. One of my pet peeves about Lunacycle in the past is when they sell a 50 Amp Ludicrous BBDHD on a bike with a Hailong based ‘shark pack’. The Hailong shark batteries can only put out 50 amps for just a second or so and then drop back down to the 30ish Amp range. This ends up feeling like you bought a racecar that you can only get 60% of the power out of. The Wolf packs have been a long time coming and with a 14S4P configuration and 30Q cells they can easily put out 50 Amps continuous without significant voltage sag. To be fair with only a 12Ah pack if you pull 50 amps continuous the pack will only last about 15 minutes, but it’s unlikely that anyone would really do that...

Stainless steel lends long life to Merkur wind farm structure

High-performance duplex stainless steel is playing an important role in ensuring a long life for key components at Merkur Offshore Wind Farm near Borkum Island in the North Sea. The wind farm is one of Germany’s largest, with 66 turbines generating 1,750 gigawatt-hours per year, enough to cover the energy needs of about half a million homes. With offshore wind farms like Merkur expected to generate energy over an operating life of 25 years, operation and maintenance typically accounts for 15-25 percent of their total lifecycle cost. Smart specification of materials for important components can minimise the need for inspection and maintenance and help operators to control costs. This is particularly true for the transition pieces that form part of the foundation structure of the monopile turbines supplied by Windar Renovables and Idesa for Merkur. In monopile construction, a single pile is driven into the sea bed and a transition piece is fed over it like a sleeve, with the turbine secured on top. Once in operation, the turbine will export power through a cable connection that runs through the transition piece, which must be water and air tight to protect the interior from corros...
