How much ice do you need to get your drinks cold when using a cooler? According to estimates from Business Insider, the ratio is ten pounds for every 12 drinks. That's a lot of ice—the weight of the coolant ends up being far heavier than the weight of the drinks you and your friends are about to enjoy. Plus it costs $1-3 each time you fill up your cooler. The volume needed for ten pounds of ice is wasted space that could fit plenty of extra cans or bottles of beer. But if no ice is needed to keep your drinks cool—which is the situation with such electric devices as GoSun's solar cooler—then the math is very different. Before we talk about the carrying capacity of solar coolers, let's take a closer look at the calculations that show us how much ice we need to chill a drink. Here's how they break down the math: Let's say I have one can of soda or beer... I am assuming the drink (and the aluminum can) start at 22 degrees C. The key here is that the chang

GoSun is always trying to push the technological envelope on electric appliances. We've done the same with electric coolers and are proud to say that the new GoSun Chill solar cooler uses only half the power compared to a regular car fridge. Here's the competition breakdown: The contenders: A GoSun Chill vs. a car fridge. Both carry 40 liters. The scenario: For a control they were both placed outside on a 75°F sunny day. Both were cranked down to 40°F. They were tested side-by-side to remove all variables such as wind speed, outdoor air temperature, nearby shade, and other factors. The result: The Chill used half the energy of the car fridge. Here's a more detailed breakdown. The chill used half the energy. Using an IR scanner, infrared camera, and a Kill a Watt Meter (energy consumption tracker) you can see below how the Chill is using .03 kilowatt hours (kWh) vs. .06 of the car cooler. The total difference in electricity usage over the course of th

A solar powered cooler for camping has numerous advantages over a regular cooler. Here are three of them (although these advantages may not apply to all models of solar coolers). Scroll down to the bottom of this post to see how much more beer you can hold in your solar-powered cooler for camping. First, there is no need for ice. Tired of having food turned into a soggy mush if it isn't protected by three layers of Ziploc bags? Tired of having to drive into town every 24 hours to replenish your supply of ice? Tired of being unable to completely disconnect from the grid? A solar powered cooler for camping is the way to get out of the ice age. Plus you can now utilize 100 percent of the space within a cooler when ice isn't part of the equation.  Second, solar powered cooler for camping can ironically help you to stay more grid connected by being able to recharge your electronic devices. In the case of the GoSun Solar Cooler, it is powered by a portable lithium battery

April 22 is Earth Day, so what is one of the easiest Earth Day activities you can get involved in to help out the Earth? One of the best, but most overlooked, ways is to find a better way to cook. Some three billion people worldwide rely on dung, wood and charcoal to cook their food--with catastrophic effects on the environment Residential solid fuel burning accounts for 25% of global black carbon emissions, about 84% of which is from households in developing countries. In South Asia for example, where more than half of black carbon particles come from cookstoves, black carbon also disrupts the monsoon and accelerates melting of the Himalayan-Tibetan glaciers. As a result, water availability and food security are threatened for millions of people. These problems are compounded by crop damage from ozone produced in part by cookstove emissions and from surface dimming, as airborne black carbon intercepts sunlight. But solar cookers can conservatively save two metric ton of

There's no environmentally cleaner way to keep food cold than a solar fridge (save a root cellar, and most of us don't want to live in a house built in the 1840s). Unlike conventional refrigerators, which run on electric that is likely generated by burning fossil fuels, a solar fridge runs on energy provided directly by the sun. Solar fridges are the best sort of coolers for off-the-grid locations where AC power is not available and no conventional fridges dare to tread. They can keep food preserved without the need for utility-provided power, a major advantage in undeveloped areas where electricity availability is intermittent and unreliable. Solar fridges use thick insulation and a DC compressor (not AC) to cool food. Older forms of solar fridges used a combination of solar panels , inverters for the AC power, and lead batteries to store enough energy for cloudy days or at night when the absence of sunlight meant the absence of power input. Lead batteries were heavy a

So you have found out about sun oriented cooking, you have been on the web and seen the photos and articles, you have perhaps been to sun-oriented cooking reasonable and possibly you have even eaten sunlight based prepared dinner. Presently you need to take it to next legitimate sun oriented dimension, you need to turn into sunlight based culinary expert and buy a sun-powered (sun) broiler, yet where to begin and what criteria conceivably impact your choice.  Natty gritty and all around showed sun broilers plans are promptly accessible on the web. This will irrefutably be your most economical choice. The drawback is this methodology is inclined to a human mistake on the off chance that you don't adhere to the guidelines effectively, and these broilers regularly are not especially rough or hearty and won't really keep going quite a while. Your dimension of moderateness assumes a job in the decision too. While all sun based stove makers clearly have a work in edge with t
