To my knowledge no one has succeeded on the market with a treadle pump with plastic cylinders because they are not durable enough. Glad to see someone is still working on this, as PVC is much easier to work with than metal. My two comments looking at your photographs and manual. First I think the cylinders are not well enough supported and will not take any abuse. Test the pump with children or teenagers:) Second I think the piping is too small diameter relative to the cylinders and the majority of your energy will be spent overcoming pipe friction, resulting in a greatly reduced flow rate.

Can you ask them to contact me re the issues outlined in my previous post? I would very much like to pursue the use of the design they developed, but have been at a standstill for months. Thank you for any help you can provide. Anyone out there who knows any of the individuals in the team picture above? Can you ask them to contact me re the issues outlined in my previous post?

This page may be old but I just caught wind of this through an Engadget link and I have to say I'm really impressed. And it's wonderful how you guys are sharing all the hard work you put in with everyone else. Really, this concept is quite valuable (money-wise) and it's admirable that you're giving it to the world. I really want to build one myself and when I return to the provincial country-side of the Philippines, I'll look forward to giving it a go and sharing this with them. But by the way, could you give any updates for the revisions you've made. I'd like to hear how that new adsorber with the pipes worked out for you. All in all, great work! And that design pdf was a great read! The only problem was that it wasn't developed by a Hawkeye! Just kidding. But it's great to see the Big Ten in the news! And to come across such a valuable contribution like yours coming out of it. MSU should be proud! Brilliant work guys!

Have been looking into renewable energy sources that i can just setup at home, and solar energy was a definitely on my checklist. The post is just making me want to get some small solar panel systems installed on my roof so bad. I initially planned to buy them, but they are quite expensive at the moment, think im gonna look up a way to build some cells at home and give em a whirl. Well, thanks again for the post, really good insight into this area. Hello!

Here are some things to keep in mind: --Don't overwater. The heat from traditional lamps causes water evaporation, requiring indoor gardeners to give their flora extra water. Because LED lights produce significantly less heat, plants require less water. --Provide some heat. On the flip side, the lack of heat generation from LED lights can cause plants to grow more slowly. Plants should be kept in a room that's 70-80 degrees Fahrenheit, and a small 60-Watt light bulb may be needed for plants that benefit from higher temperatures, such as tomatoes.

Replacement light bulbs have been made as well as dedicated fixtures and LED lamps. LEDs are used as street lights and in other architectural lighting where color changing is used. The mechanical robustness and long lifetime is used in automotive lighting on cars, motorcycles and on bicycle lights.
