http://www.poundaweek.ca/ A smart calorie counter app with AI - Analyzes the foods you eat, how active you are and the progress you make to automatically set nutrition targets designed for you, every single week. We've helped users lose over 20,000 lbs.

how do you guys do things differently compared to MyFitnessPal? I recently started using MFP and it's been useful in that I know how much I'm eating (whereas previously I was just wrongly guesstimating with some mental math).

I love your concept, just curious what sets it apart.

Other Calorie Counters - Set your diet targets once based on a generic formula.

Poundaweek - Uses Artificial Intelligence to update your nutrition targets EVERY week.

Other Calorie Counters - Don't provide any coaching. If you get stuck before reaching your weight goal you are on your own.

Poundaweek - Learns from you and provides personalized weekly reports, so you continue making progress towards your weight goal.

Earlier quoted context omitted.

Thanks! The size we're targeting now is a system of two kites on one tether, each with a wing span of 20 m and weighing 1650 kg. This would generate around 1 MW. The largest off-shore wind turbines right now have 80 m blades and generate 8 MW at a weight of 1300 tonnes (excluding foundation), but the main reason they are so large is economies of scale, off-shore wind turbines are expensive. Kite wind turbines do not…

But with a traditional wind turbine with 80 meter long blades, the total "footprint" for each one is roughly a 160 meter wide circle. In principle you don't need much space between those circles in a bigger wind farm (but because of turbulence and the wind shadow there usually is). What is your "wind farm" model? Reserving a kilometer wide circle for each kite pair does not really seem feasible even off-shore.

The wind shadow from a traditional wind turbine is actually very significant. For example, at the London Array, a very modern wind farm, they have 175 wind 3.6 MW rated turbines over 90 square kilometres, so about two per square kilometre.

Some scholars believe that kite energy can best this by a wide margin. For example, you can put the kite systems at alternating heights to combat the problem with wind shadow, and there is no reason why you wouldn't be able to have a significant overlap in the circles, since the wind will be blowing in close to the same direction throughout the wind farm.

http://kitex.tech We're building a new type of wind turbine that generates energy using significantly less material, making it much cheaper to install. We do this using huge fixed wing kites made of carbon fibre, and drone technology.

Interesting area to work in.

There's huge interest in renewables here in China and a great deal of windy Himalayan mountain peaks that have been covered with wind generators here in Yunnan province (far southwest China) in the recent past. Also solar and hydro is everywhere. Lots of e-vehicles too, everything from golf buggies to cop cars to buses to taxis to bicycles to cars to old-person mobiles to tractors.

Also coming from Australia with Scottish heritage, I wonder if you could use this to power long distance autonomous e-vehicular trucking through remote high wind land areas?

We also have awesome high altitude lakes for kite surfing (Fuxian in particular), I used to sail Weta trimarans there, but sold them last year. Motor boats are banned. You guys should come visit!

so this is actually a relatively large market for adult themed material based on this idea and there are several different versions out there, each with its own focus.

I think the biggest one is http://www.bearchive.com/~addventure/

which is a better version of the original addventure http://www.addventure.com/

there are other, non-adult, versions as well but they don't see as much traffic.

*i just realized i definitely went to that site to check that the link was working on my work computer, so thats going to show up as a flagged site in my history now. great :/

https://plan.university - plan.uni A free course schedule planner for college students, platform to connect with people within classes and soon the way graduates will find the job they are uniquely qualified for. Write me at kaiser@plan.university if you think your college/university would need plan.uni as well :)

As a class project we wrote a Chrome extension that transformed our university's terrible course offering page into something like this (but less ambitious) It was a pretty big hit and continues to be used even 3-4 years later.
