Build a DIY Portable Solar Power Generator For Under $150 | Solar Burrito - Tools for Living Off Grid Want to build your own portable solar power generator to take with you on camping trips or for use in an emergency? I’ll show you how below, it’s easier than you think. Goal Zero’s version of this cost over $400 and doesn’t include any solar panels! How portable do you want your solar generator to be? Think about how heavy and large it should be? Video showing components: The Container First I bought a case that would be a good jumping off point that I could fit a 10 watt solar panel on and in. Here you can see the 10 watt solar panel is removable and attached with velcro on metal strips. Closeup on the main power switch. Notice round switches to the right of the inverter and volt meter. portable solar generator wiring diagram Below I show you what I used and suggest for building your own DIY portable solar generator. Choose Your Charge Controller Get This Battery (high power AGM) Choose Your Inverter (size to your battery/needs) Choose a Volt Meter (optional but fun)
Heating Water with Solar Energy | | DIY Radiant Floor Heating | Radiant Floor Company Introduction Solar water heaters are commonly used as heat sources for radiant floor systems in regions where an abundant solar resource is available. Normally, a large solar heated storage tank (with electric, gas, or oil backup) supplies hot water to the radiant system and most often provides for domestic needs as well. Solar heaters interface well with radiantly heated floors because the large thermal mass common to radiant systems provides an excellent storage medium for the energy generated during the day. The following schematics illustrate the components necessary for a solar based radiant floor heating system. Sensor Placement Unless you’re using a “PV Direct” solar thermal system (see above schematic), two sensors are required when a solar differential controller (solar relay) is used to trigger the pump sending fluid from the collectors to the solar storage tank. Some solar storage tanks have a designated sensor port near the bottom of the tank. Flat Plate Solar Panels

Free-Energy Devices, zero-point energy, and water as HHO fuel Build a Simple Solar Air Heater - Renewable Energy After walking into my workshop one December morning and feeling a bone-chilling 10 degrees, I decided to install a heating system. Given the rising costs of propane and my family’s environmental concerns about using nonrenewable fossil fuels, a solar solution seemed fitting. I’m a retired aircraft engineer, but you don’t need a similar background to tackle this project. I reviewed many solar collector concepts and decided to install a thermosiphon air collector on the south wall of the workshop. To minimize costs, I integrated the collector with the structure and used readily available materials. The thermosiphon collector consists of clear, corrugated polycarbonate panels fastened to 2-by-6-inch studs. At night, airflow reverses as air in the collector cools to outside temperatures. Performance and Economics On sunny winter days, the collector raises interior temperatures to between 60 and 75 degrees. Be sure to install adequate insulation and to control air infiltration.

Six Famous Thought Experiments, Animated in 60 Seconds Each By Maria Popova From the fine folks at the Open University comes 60-Second Adventures in Thought, a fascinating and delightfully animated series exploring six famous thought experiments. The Paradox of the Tortoise and Achilles comes from Ancient Greece and explores motion as an illusion: The Grandfather Paradox grapples with time travel: Chinese Room comes from the work of John Searle, originally published in 1980, and deals with artificial intelligence: Hilbert’s paradox of the Grand Hotel, proposed by German mathematician David Hilbert, tackles the gargantuan issue of infinity: The Twin Paradox, first explained by Paul Langevin in 1911, examines special relativity: Schrödinger’s Cat, devised by Austrian physicist Erwin Schrödinger in 1935, is a quantum mechanics mind-bender: For more such fascination and cognitive calisthenics, you won’t go wrong with Peg Tittle’s What If….Collected Thought Experiments in Philosophy . via Open Culture
