Converting Carbon dioxide CO2 into Formic acid using solar power.
Global warming is being caused by rising levels of atmospheric greenhouse gases, such as carbon dioxide Co2. Research to reduce this Global warming, usually involves three areas First, Developing alternative energy sources, Second, capturing and storing greenhouse gases, and Third one, repurposing excess greenhouse gases. By addressing two of these 3 things, researchers at Princeton University and researchers at a New Jersey startup company Liquid Light , came up with an efficient method for harnessing sunlight to convert carbon dioxide into a potential alternative fuel known as formic acid. The transformation from carbon dioxide and water to formic acid was powered by a commercial.
Solar panel that can be found at electric poles across New Jersey. The process takes place inside an electrochemical cell, which consists of metal plates the size of rectangular lunchboxes. To maximize the efficiency of the system, the amount of power produced by the solar panel must match the amount of power the electrochemical cell can handle. This optimization process is called impedance matching. By stacking three electrochemical cells together, the research team was able to reach almost 2 percent energy efficiency, which is twice the efficiency of natural photosynthesis. It is also the best energy efficiency reported to date using a manmade device.

Here is the main greenhouse and another view, you can see across the property this greenhouse is a work in progress as well but well along. It has only been in operation about eight months It has a back water wall for thermal storage nice windows for the greenhouse, and he's growing carrots, tomatoes, and again this is starting up in powered by those little babies ltfishgt right now Here's a fig tree that he just took a cutting branch and stuck it in and it started. And that was less than 8 months ago.
Solar powered air conditioning
Music playing Narrator Over 50 percent of the greenhouse gas emissions you produce in your home are generated by heating, air conditioning and hot water. In other words keeping your home warm in winter, cool in summer with nice hot water on tap is emitting 2.5 to 5 tonnes of greenhouse gas emissions each year. It also contributes a hefty amount to your electricity bill, between 50 to 60 percent. CSIRO has invented a new solar air conditioning system for Australian homes. This technology solution will reduce Australia's emissions, reduce your energy.
Bills and reduce our demand for electricity and gas. If every home in Australia installed our solar cooling technology it would be the equivalent of saving 15 mega tonnes of CO2 or taking 3.5 million cars off the road. CSIRO's solar air conditioning is an innovative three in one technology that provides hot water, cooling and heating. It uses only a fraction of the electricity of current systems and halves greenhouse gas emissions. The process begins with a typical solar hot water system. Water is heated by solar panels and stored in the hot water tank.
This solar hot water can then be used throughout the home, reducing the need for gas or electricity. A portion of the hot water is diverted into CSIRO's new solar air conditioning unit, which is divided into two compartments. The hot water enters a heat exchanger in the first compartment of the unit. Similar to a car radiator the heat exchanger uses the hot water to heat outside air that has been drawn into the first compartment through the vent. At the same time outside air is also being drawn into the second compartment into a desiccant wheel.
The desiccant wheel is the most critical part of the system. It is used to dry out the air before it goes into the house. Slowly turning the desiccant material in the wheel continuously absorbs moisture in the second compartment and then the absorbent material dries out in the first compartment. The desiccant material is dried out using the hot dry air generated by the heat exchanger. This air is then exhausted outside the home. The dry air from the desiccant wheel flows through an indirect evaporative cooler which creates a stream of cool dry air.

Is solar affordable, does it work in our area, Do we have enough son. and answer to all those questions is Yes We use Sun Power Panels from rooftops to ground mount. Percy and pay back on the system is lowest. Four years is a very short term investment for a product this warranty for 25 years. You own your house why do you rancher your power.
Solar potential estimation by using LiDAR data
Buildings roofs solar potential estimation is an important topic for PV systems' investors. Input classified aerial LiDAR data consisting of buildings, terrain, and vegetation. The LiDAR point cloud is inserted into regular grid with 1m2 resolution percell. LiDAR data provides excellent topographic details for the calculation of percell slope angles. Furthermore, the percell aspect angles are calculated. Spatiotemporal shadowing simulation is done with a 10min timestep. Additional shadowing is considered from the sorrounding terrain using lowresolutional DTM data. The redmarked area represents the highresolution LiDAR data. This represents multiresolutional shadowing model.
Local researchers develop efficient, affordable multilayer cultivation system
Local researchers have developed a new multilayer cultivation system that can easily be installed in greenhouses. It is expected to help boost productivity because it uses space more efficiently and costs a fraction of existing systems, which will in turn help farmers increase their income. Paul Yi has more. This is a hightech plant factory in Korea established in 2011. The environmental conditions in the room are automatically regulated by a computerized system that controls the indoor temperature and the amount of light, carbon dioxide and a nutrient solution. Plants can grow all year round without being.
Influenced by external factors. The problem is the high installation price, which can be up to 15hundred U.S. dollars per square meter. Now, local developers have come up with a more affordable cultivation system that allows them to grow fresh lettuce in trilevel beds. The lettuce growing on the top layer receives sunlight, while the two layers below get additional light from special fluorescent lamps to supplement the solar energy. The cost is only oneeighth that of the existing plant factory, at only 180 dollars per square meter. Productivity, on the other hand, is four times higher than at regular greenhouses with hydroponic.
The Aquaponic Greenhouse Funding
Hello! I'm Rob Torcellini and welcome to Bigelow Brook Farm! We're about to start on a huge new project and need your help to meet our goal. I have purchased two used 26' wide greenhouses totally nearly 200' in length. My goal is to construct one aquaponic greenhouse and have it functioning for the fall of 2016. Over the years, I have created hundreds of free tutorials on YouTube and I will continue to produce these tutorials to help educate and maybe even provide a little entertainment. However, these tutorials are very time consuming to produce. Depending on the complexity of.
The editing and number of diagrams for each tutorial, it can take between 1 to 2 hours of postproduction work per minute of completed footage. Typically it's 58 hours of editing. Even though our YouTube subscriptions and views continue to rise, the ad revenue continues to dwindle. We've joined the crowd funding site Patreon to help raise funding to continue producing tutorials and provide the needed revenue for the new aquaponic greenhouse. For a very small pledge you can gain early viewing of our tutorials, access to our premium web site containing.
Spreadsheets, diagrams, and frequently asked questions, or have a permanent advertisement embedded directly into a tutorial which can't be blocked, reaching 10's of thousands of targeted viewers. The Patreon concept is very simple, you just pledge a small payment for each tutorial that we release. If it's a slow month, no payment is made. If we produce a bunch of tutorials, you have the ability of capping your total contributions per month. As always, our tutorials are still free to watch, but with your support, you will gain access to additional insider knowledge about our.
Cooling a Greenhouse with a Cooling Wall
Nate All right this is Nate Storey with Bright Agrotech, and today we're going to talk about a really simple and inexpensive way to cool your greenhouse. It is the summertime and things are getting hot, all of that excess sun from early in the morning to late at night, the ground is heating up, the plants aren't using all of it, and a lot of it is trying to heat inside our greenhouses. So, if you are in a dry or arid climate where you don't have an awful lot of humidity, cooling walls are absolutely the best way to cool your greenhouse.
Off. Now, for those of you who are going to say, Oh, well cooling walls are really expensive and I don't know if I can afford one. Today we're down at Bayberry Fresh and we're going to walk you through this homemade cooling wall. All right, so this is a really simple device, it is essentially this big cardboard pad. This cardboard has channels running this way, channels running this way. At the top, we basically have a PVC pipe up here, I'll let you guys get a shot of that a little later,.
But there's holes in that PVC pipe and what it's doing is, it's pumping water up from our sump over here, pumping up through this PVC pipe and it just trickles out to the top of this pad. As the water moves through this pad, and yo can see how wet that is, it is just dribbling down through there. The fans at the other end of the greenhouse are pulling air through there, so all of that air as it is pulled through this wet pad, it's cooling our air. We've got really dry air coming in, it comes out on this side, with a little more.
Humidity, and it is way cooler. These are by far the easiest and the most best cost effective way to cool these things. You can buy these pads on laces like Hydrogardens, Greenhouse Megastore, they will just sell you these raw pads, so you can rig these up. You can see he's just got them rigged up with 2x4's, he's got a 6inch PVC pipe down here cut in half, to capture that water. It all just kind of runs back down towards this end and drops into our 55gallon barrel. So instead of going out and spending thousands on a premade,.
Prefabricated cooling wall, you can make your own really easily, really inexpensively, and you can get a lot of work out of it. This wall here is cooling the entire greenhouse, and right now there is only one fan running. So one fan is running, it's pulling air through this pad, and cooling the entire greenhouse. Pretty simple. Pretty easy. Plumbing wise, again, we've got this 6inch pipe capturing this water. Down here you're going to see we've got this pump, sitting in this 65gallon barrel and it is pumping that sump water up,.
Through the pad. Now the only caveat with these walls is that they do tend to use a lot of water. Hayden was telling me he goes through like 3040 gallons a day on this cooling wall to keep this place cool when the weather is really hot. That's something to keep in mind. If you don't have a lot of water, maybe think about it. But this is going to be the cheapest possible way to cool your greenhouse off in the heat of summer. Thanks so much for watching today. I hope this tutorial was useful to you, if you have.
