Designer creates solar powered oven to cheaply freshen salt water

first_img © 2012 Phys.org Diamanti says he came up with the idea for the Eliodomestico while visiting friends working for non-governmental agencies (NGOs) in third world countries, trying to help those in need. What he heard was that there was a great need for fresh drinking water. What he saw was that one resource they all seemed to have in common was lots of sunshine, which of course got him thinking about using solar energy to distill water. Boiling salt water to create steam that collects on a surface and then drips off as fresh water isn’t new, it’s a technique that’s been around for thousands of years. What’s new here is the idea of using the sun and no moving parts to boil the water using materials available almost anywhere.Using those simple constraints Diamanti came up with a design that he believes should work. It’s made of clay and pottery along with simple metals that can be easily welded. It works he says, like an upside down coffee maker. It has two parts, an upper boiler and a lower oven. Saltwater is poured into the boiler through a hole in the top that has a screw-on cap. As the sun heats the water to boiling, the pressure forces the steam through a metal tube that reaches down into the oven below where it collects on the top of the oven and then slowly drips down into a collector basin at the bottom, which is not only easily removable but is flat bottomed, allowing for carrying atop the head, a common method of transport in many third world countries.The whole concept is open-source which means anyone, anywhere that wishes to make one of his ovens is free to do so without having to pay for licensing. They’re also free to modify the design to suit local needs as well. Diamanti is hoping that NGOs throughout the world can set up micro-loan projects to get the ovens built which can then be sold at very low prices to those in the local area. One oven is enough, he notes, to serve a family of four for a day. Explore further More information: This document is subject to copyright.

Copenhagen tap water safe again after E.coli scare: city Citation: Designer creates solar powered oven to cheaply freshen salt water (2012, September 7) retrieved 18 August 2019 from https://phys.org/news/2012-09-solar-powered-oven-cheaply-freshen.html (Phys.org)—Designer Gabriele Diamanti has created a solar oven he calls the Eliodomestico (household-sun); its purpose is to boil saltwater to produce clean drinking water for people in places where such water is difficult or impossible to obtain. What’s unique about the Eliodomestico is that it’s been designed in such a way as to be easily built by local people, rather than elsewhere and shipped in. This way, the profits from making and selling the oven remain local. via humansinventlast_img read more

Loosen Up Here Are 6 Ways to Get More Comfortable on Camera

first_img Growing a business sometimes requires thinking outside the box. June 22, 2016 Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global As of the start of 2016, 65 percent of senior marketing execs cited visual assets, like video, as critical to telling their brand’s story. What does that mean for you as a businessperson? It’s time to get comfortable in front of the lens. Embracing video opens up a whole new realm of ways to reach your target audience, from media appearances to new social staples like Periscope. Here are six ways to feel more at home on camera.Related: How To Make Your Business Messaging Effective In The Age Of Video1. Don’t wing it.Even if you’re the type who excels at flying by the seat of your pants, I beg you — don’t wing it the first time you’re going to be on camera, especially if it’s live. I’ve seen many a cool cucumber melt into a blubbering mess when a camera lens is shoved in their face, This can be avoided with a bit of preparation.2. Wear something comfortable and camera-friendly.If you don’t typically wear a three-piece suit, it’s probably not best to don one during your on-air debut. Wear what you’re most comfortable in while still looking polished. A pressed button-down in a solid, jewel-toned color feels easy-breezy and looks great on camera.Related: What to Wear When You’re In Front of the Camera3. Don’t give the death stare.Your natural instinct will probably be to stare directly into the camera lens. This is a normal urge, but it looks totally awkward if you never break your gaze.Instead of giving the death stare, think of it as having a conversation with a friend. You’d make eye contact, but you wouldn’t stare them directly in the eyes the entire time. It’s the same on camera. There are natural breaks when you might look away from the lens as you speak or listen to someone else speaking. Practicing in advance will help make this feel more natural.4. Go in with a game plan.If you’re appearing on camera for something pre-recorded — say, a promotional video — it might make sense to write and follow a script. But if you’re being interviewed by another person or are appearing on live television, it makes more sense to go in with a basic outline of what you want to talk about rather than a word-for-word script. Your responses will sound more natural.On an index card, write down five to 10 high-level bullet points with key words and phrases that will jog your memory of what you want to talk about. If you lose your train of thought, you can easily refer back to it and move on to the next point.Related: Let Customer Get to Know You With Video5. Don’t be afraid to pause and collect your thoughts.When appearing on camera, it’s not uncommon to lose track of what you were saying or go down a verbal rabbit hole that leads nowhere. If this happens, try not to get flustered. Simply take a breath, collect your thoughts, and begin again from the next bullet point on your list. Any pauses in speech feel infinitely longer in your head than they are in real life, I promise.6. Avoid the urge to pick yourself apart.If you’re not accustomed to seeing yourself on camera — or hearing your recorded voice — it’s easy to be your own worst critic. Go easy on yourself!The tiny quirks you notice about yourself are barely a blip on anyone else’s radar. Plus, no one gives a flawless performance on their first on-camera go-round. Practice makes perfect, and with a few trial runs you’ll be a video pro in no time.Want more actionable steps for getting more face time on camera?
