Soluciones de recarga para vehículos ✅ Energias. Немецкая SolteQ предлагает солнечную черепицу по цене обычной кровли. Создание полноценной кровли, которая не только надежно выполняет свое основное назначение, но и способна стать украшением дома, производить электроэнергию и тепло, иметь срок службы не менее 50 лет и стоимость обычной крыши (в которую уже входит интегрированная солнечная электростанция) – цель немецкой компании SolteQ и ее основателя Беркая Байера, который, как и Tesla, намерен трансформировать энергетику за счет солнечных крыш.
Но в отличие от изделий американского конкурента, немецкий продукт может оказаться более эффективными и доступным. «Сегодня относительно легко и недорого на 90% отказаться от ископаемого топлива. На мой взгляд есть два перспективных источника «зеленой» энергии: первый – солнечная энергия и второй – энергия ветра. Хотя солнечная черепица разработана уже давно, она не была готова к крупномасштабному серийному производству и продавалась только в ограниченных количествах. SolteQ разработала комплексные решения для кровли домов. Scientists Develop Solar Cells That Can Be Ink-Jet Printed.
3D printing promises to be the renewable energy source of the future, but modern manufacturing techniques are a little lacking.
A team of scientists and engineers from Alto university have come up with a method of producing solar cells through ink-jet printing. The technology is so much like printing that cells can be made in any sort of image you desire, like the one of the team below. [Image Source: Alto] “The slow process in which the light absorbing dye molecules are adsorbed from solution on the nanocrystalline TiO2 photoelectrode film has been a handicap to the fast and cost-effective fabrication of dye-sensitized solar cells (DSSCs) using printing techniques.” ~ Hashmi The key market potential seen in this technique is self-illuminating signage that would require no wiring or electricity.
According to Futurism, the team tested the panels over the course of 1000 heating and light cycles and found absolutely no decrease in efficiency. Advance Voltage Drop Calculator and Voltage Drop Formula. According to the NEC (National Electric Code) [210.19 A (1)] FPN number 4 and [215.2 A (3)] FPN number 2, the allowable Voltage drop for feeders is 3% and the acceptable voltage drop for final sub circuit and branch circuit is 5% for proper and efficient operation.
For example, if the Supply voltage is 110V, then the value of allowable voltage drop should be; Allowable Voltage Drop = 110 x (3/100) = 3.3V. We have already discussed the selection of proper size of cable for electrical wiring installation in SI and British system with examples. In the above article, we have also explained the voltage drop calculation and voltage drop formula and online cable size calculator. Today, we are going to share Online Advance Voltage Drop Calculator and Voltage Drop formulas in detail. →Also check. Homemade Wind Generator - Renewable Energy.
Are you headed for the beach or going camping in the mountains?
Maybe you live on a boat, visit a remote cabin or you're living off-grid. Electricity is yours for the taking as long as the wind is blowing... And you can get it on the CHEAP with an easy homemade wind generator. Light up that storeroom, barn or use the generator to keep all your vehicle batteries charged too. TESLATECH ONLINE RESOURCE CENTER. Solar Power For Homes In Bahawalpur Pakistan By Zakria. Off grid contracting your prepping and homesteading contractor. How To Build Wind Generator using Floppy Stepper Motor.
Floppy drive wind generator is a quite simple DIY project.
Construction does look like a toy, but it can come handy in various occasions: camping, fishing, sailing or wherever power greed is not available. Small wind generator can power or recharge AA/AAA batteries (Ni-Cd, Ni-Mh), mobile phones, MP3 players. You can connect light bulbs, LED light or similar devices that draw up to a few watts. Windbelt Cheap Micro Wind Generator. Find out more about Windbelt - an affordable efficient micro wind generator home > wind | newsUnlike PV solar panels, wind turbine generators do not scale downwards well.
While large wind turbines can generate huge quanties of electricity very efficiently and relatively cheaply, as the size of the wind turbine is reduced, efficiency reduces and cost per Watt power jumps enormously.Windbelt offers an alternative for small scale wind power generation dispensing with the turbine altogether while producing power at a (claimed) efficiency of 10-30 times greater than that of a similarly rated wind turbine. Windbelt Wind Generator Windbelt is an innovation of Shawn Frayne (pictured above) a 28 year old inventor from California, USA. Frayne developed a simple device with a taut Mylar membrane fitted with a pair of Neodymium magnets that oscillate in and out of coils of magnet wire because of the mechanical resonance of the taut membrane with wind blowing across it.
