Welcome to the Free Appropriate Sustainable Technology (FAST) research group run by Professor Joshua Pearce, the Thompson Chair in Information Technology and Innovation at Western University in Canada, a top 1% global university. We are interested in exploring the way solar photovoltaic technology can sustainably power our society and how open-source hardware like open source appropriate technologies (or OSAT) and RepRap 3-D printing can drive distributed recycling and additive manufacturing (DRAM).
Thanks - here is the first paper on the first one - www.appropedia.org/Net_Zero_Agrivoltaic_Arrays_for_Agrotunnel_Vertical_Growing_Systems:_Energy_Analysis_and_System_Sizing
Such a pleasure to have participated in this panel and conference. Thanks to Western, Ivery and the FAST team for making this come together once again!
Sorry not sure why they took it down - full paper is here along with file links - www.appropedia.org/Open-source_3-D_printable_autoinjector:_Design,_testing,_and_regulatory_limitations
Hello. I did everything you said. My Arduino code worked, but no image appeared on the LCD screen and the buzzer started beeping. What is the problem? Can you help me?
You could probably do it-- but the big challenge with PET is it has to be bone dry and stay that way while thermally processing -- we have had better luck with FGF/FPF printing of PET waste - see what we did with full PET bottle regrind (that has 10% HDPE from the caps included) - warning this is not a great material to work with: www.appropedia.org/Multi-material_distributed_recycling_via_material_extrusion:_recycled_high_density_polyethylene_and_poly_(ethylene_terephthalate)_mixture
DO NOT EVER USE FOR EPINEPHRINE. THIS IS FOR SUBCUTANEOUS DRUG DELIVERY AND NOT INTRAMUSCULAR. ALSO, EPINEPHRINE IS UNSTABLE AND SHOULD NOT BE STORED IN THESE SYRINGES DESIGNED FOR TRANSIENT USE. PLEASE TO DO NOT TAKE RISKS WITH LIFE SAVING MEDICINE.
fantastic work! We are working with a couple of Power companies in Vermont. I'm an electrical engineer and we are deep diving the PV generation issue. We've constructed a number of timberframe solar carports and are actively putting communications/controls to generators statewide. We are all in on the solar revolution. I read your vertical photovoltaic system paper several times and will be building a unit based on your design after the weather clears. I think you are onto something significant. Why I love your design. A couple of significant advantages your design improves: first. The "duck curve" problem. Not all generation has the same value. By shifting to an east-west orientation on your bifacial panels you generate more energy during the morning and afternoon that could "bart head" the generation curve thus mitigating the "duck curve" problem. Many of the power company substation transformer name plate capacities have been exceeded by the introduction of too much south facing generation that triggers the need for expensive batteries or generation peakers to shift the generation usage to morning [6-9 am] and evening [6-9 pm] . The duck curve issue is a huge problem. It basically shut down Net Zero metering in california....NEM3 and threatens the entire industry. second. All Seasonal generation is not created equally. In high snow load conditions many South facing PV installations will remain covered during winter months. The systems have too much generation in the summer months and too little generation in the winter months. By going vertical and using bi-facials your system will generate when other aren't. This should play well with the regulators thus easing the burden of permitting costs. third. By going vertical you can build on much steeper and less usable terrain. Pole lines can go up sides of cliffs. The utility scale solar people have problems with 20% grades with conventional south facing fixed arrays. BTW there are some very cost effective hot dipped galvanized construction products [bolts, plates, guying etc] that are commercial off the shelf [COTS]. They are found in the electric utility space used to construct distribution pole lines that could be leveraged in your designs. They are highly engineered and because they are used in great volumes by the power companies they tend to be very reasonably prices. These can be purchased in the open market. I'd be happy to share these insights with you.
NO NO NO! THIS IS DESIGNED FOR SUBCUTANEOUS DRUG DELIVERY AND NOT INTRAMUSCULAR AS EPINEPHRINE USUALLY IS. UPTAKE MAY BE SLOWED. DO NOT TAKE RISKS WITH LIFE SAVING MEDICINE.
in the video, you demonstrate with an 8mm insulin syringe and a very thin testing medium, but would the files linked in the paper work with a 10mm diameter syringe and a more viscous medication, or would they need to be modified? i would like to print this device to help with injecting a medication that's suspended in castor oil, so it's substantially thicker than the alcohol used in testing or the insulin this is presumably designed for.
@@FAST-GROUP good to know, we'll give it a shot, and can toss it into fusion360 to check dimensions before printing, thanks for the suggestion about spring strength 😎👍
If i have water desalination plant currently powered with national grid and i want to design hybrid renewable energy system wind and solar should i use HOMER GRID or HOMER PRO
it is good explanation how to fix the error 'There was an error reading library item named ‘default’ for component type converter. check your default settings in the library for this componen't for HomerPro-3.11.2_x64
Maybe stable speed and high torque at small rpm . . . I use it too . . but mine is Nema34 with 3:1 gear reduction . . and whole system gives around 1kg per hour.
