Jenni is a gateway device for small-scale solar for apartment & condo dwellers - Treehugger

While she charges you can plug in your phones and laptop and let them charge from Jenni rather than the grid. The current state of solar technology has enabled a whole new energy revolution, as system costs drop while grid prices rise. She anticipates charging needs assessing weather and charging patterns to make appropriate re-charging decisions to make sure you always have power. The Jenni Hub can also be charged via the grid (110-220V AC) or another 12 volt system, and the inner-facing side of the window solar panel can be used as a whiteboard, a calendar, a corkboard, or a picture frame. However, even though residential solar is now more attainable than ever, for those who don't own their roof or have the credit and capital to invest in a rooftop solar array, clean energy isn't really an option. The Jenni solar charger and battery pack aims to make it easy to begin going solar at home, starting with your portable electronics. The Jenni Hub is powered by a hinged 5W solar panel attached to the device, which can be augmented with one or more of the 20W window panels that can be affixed to a south-facing window, and portable electronics can be charged from any of four USB... Jenni measures 2 inches high by 10 inches wide and long, and weighs in at about 2. 2 pounds, so it could be used as a portable solar charger and battery bank, but the device is designed to be a home energy accessory that connects via WiFi to keep... Some utilities may offer a renewable energy option for customers, and there are companies such as Arcadia Power and SunPort that purchase certified renewable energy certificates to offset their customers' electricity usage, but when it comes to...

Reader Idea | Off the Grid: Learning About Power System Infrastructure With The New York Times - New York Times

Explicitly point out, where possible, the benefits and pitfalls of your proposed power system as best as you can anticipate them. Show, using the models we derived in class or which you have uncovered in your research, how much energy storage you may need. Keep in mind that some of your energy sources may not work all the time. Power is a measure of the rate of energy production. Electricity is the practical application of one of the most powerful forces we experience in daily life. To an electrical power plant, a city is just a giant resistor. You will provide a summary of your research along with calculations on how you will satisfy these power requirements. Please note: The cycling between active generation and using storage is generally referred to as “duty cycle. In addition, with some basic estimates of their own home consumption (a different estimate) they may get an idea of how much this quantity represents. At the same time, for many students, electricity is something that just comes out of an outlet. ” A graph of a 24-hour time period in which you expect you energy systems to be on- and off-line is another important tool to help your project. Switches allow students to think about the decisions discussed in the article about when to turn power on and off to meet consumers’ changing demands. Batteries are characterized by the amount of charge they store. Finally, students need to acknowledge the need for an inverter. The assumptions students make are less important than their realizing that they are making assumptions and providing reasonable estimates. As The Times article explains, electrical suppliers face similar challenges and often use small-scale building-sized generators that can be brought up and down quickly when demand dictates. Yet by completing this project, along with analyzing the Times article, my students gained an understanding for how electricity is delivered to their homes every day. In our analysis of the article, we discussed how the principles that govern how a flashlight works are, in a general way, very close to the model we can use to understand how cities are powered. Power integrated over time gives the total amount of energy required in a 24-hour period. You must design your electrical system so that its generation capacity and storage can provide the capability of 2kW continuously for any 24-hour period and supply 4kW for an occasional peak load. Next time, I would probably spend more time emphasizing the need to better model the calculations quantitatively all the way through to the connection to the house. This number is usually calculated in ampere hours which, when you use the definition of current, equates to coulombs ( q ) (in a real sense, a measure of how many excess electrons are in the battery bucket). In designing their power systems, many students choose either solar panels or wind turbines. Students who also did cost estimates and researched available equipment came up with price tags that were similar to estimates my son received, revealing how close some of my students’ calculations came to real-world figures. The power that comes from the batteries may be 12V or 24V DC, but the buildings require 120V AC. Suppliers have to convert voltages frequently, although they use transformers, which trade voltage for current and vice versa. I used the article as a jumping off point to challenge my students to design their own off-the-grid power system (merely from an electrical viewpoint) that can provide electricity to a cabin in a remote area. From the basic definition of power, Work = Power · t, students should be able to determine how much energy, on average, they need to store overall. To calculate how much power their voltage source will likely produce, students need to make estimates based on the specific conditions of where this system is to be set up. For example, maximum solar generation might be four hours per day. When reviewing students’ work during the project, I noticed they need to begin with the key operative constraint: the power requirement which requires they supply a certain amount of power at any given time. The Times article “ How New York City Gets Its Electricity ,” part of the New York 101 series , provided my class with an opportunity to take the topic of DC electricity (steady, non-changing currents) and go beyond experimenting with batteries,... Power from a fixed voltage source (not true in any of these arrangements, but we are making estimates) is given from the basic formula (based on the definitions of potential and current), P = I · V. But students quickly realize that the source of... The definition of voltage (potential) allows us to calculate the energy stored in a battery as: U = q · V. In the end, students need to recognize the amount of charge they need to store, times the electrical potential of the battery, must equate... Source: www.nytimes.com

Gecko camper flips and folds to make your truck home - New Atlas - New Atlas

Combining elements from roof-top tents, pop-up campers and truck canopies, the Gecko flips and folds into a two-story abode with all the amenities you need for temporary backcountry living. The 75L water tank and self-priming pump deliver water, and an available shower package supplies a hot outdoor shower. One of the head turners at the recent Australian 4x4 Outdoors Expo , the Gecko Camper rides to camp looking like an inconspicuous delivery truck, but instead of packages, it delivers a comfortable stay in the wilderness. The standard electrical package includes a 105Ah AGM battery, three 12V outlets, a fuse panel, and LED lighting in the kitchen and storage areas. Buyers can also upgrade with options like a dual battery system and solar power. The driver-side panel flips up and serves as a bit of cover, providing access to a simple kitchen with slide-out dual-burner gas stove with grill, drop-down countertop and available slide-out, drop-down refrigerator. Instead of trying to stuff a kitchen into the small camper box interior, as in truck campers like the EarthCruiser GZL and Quantis Marq , Gecko has built a trailer/canopy-style kitchen outside.
