Ultimate Awesome Over 800w of Micro Hydro Power

Renewable Energy No Comments »

I travel to a home in the mountains of Western North Carolina to meet Jay. He has come up with a way to pull a portion of water out of a creek and into two permanent magnet alternators. He feeds the power to the house to supplement what is used. Jay is using Langston Alternative Power for his setup and makes around 800 watts.
This system is making water power by spinning two pma’s that send AC power to the house. Rectifiers convert the AC power to DC power so that it can be stored in batteries. This power goes to dedicated circuits in the home. Now if the batteries voltage drops low the grid power takes over again.

How solar-powered desalination works – Sustainable clean water for islands & coastlines

Energy Efficiency No Comments »

How do you use the sun to turn seawater into clean water? Desalination using solar energy will play a crucial role to solve water scarcity.

Already 4 billion people face water scarcity. Islands and coastal areas are vulnerable to droughts. The key to unlock extra fresh water lies in the sea. However, desalination is an expensive exercise, as much energy is needed and energy rates are high.

Technology company Elemental Water Makers has found a way to use the elements in their favour. Combining the power of the sea and sun, reliable access to clean water from unlimited resources is enabled. Using unique energy recovery technology, the amount of energy required is strongly reduced. Solar-powered desalination provides independence and resilience.

Coastal communities, lower lying atolls, private islands, private properties, resorts and municipalities can now get access to affordable clean water for generations to come.

Benefit from unlimited resources today and contact Elemental Water Makers for a free feasibility study:

How greenhouse gas emissions from rice can be minimised through regenerative production

How greenhouse gas emissions from rice can be minimised through regenerative production

The global food system is responsible for between 20-30% of greenhouse gas emissions, most of which are generated at the production stage. Take rice, for example, a food staple that is eaten regularly by over half the world’s population.
Conventional rice production generates emissions equivalent to the entire global aviation industry. So how can we produce rice in a way that uses fewer resources and regenerates nature? A growing number of farmers around the world are changing the way they produce rice, by adopting an agroecological approach called the System of Rice Intensification (SRI).
This method relies on a small group of simple interventions that together significantly reduces water use, methane production, and the use of chemicals, while providing better yields and reducing labour for rice farmers.
Multinational companies who support this type of agriculture through procurement and product design can address their scope 3 emissions and build resilience in their supplier communities.
According to Project Drawdown, SRI currently accounts for 4% of rice production. If this was increased to 25%, the emissions reduction would be equivalent to that which is currently generated by the whole of India.

How Waves Could Power A Clean Energy Future

The ocean’s waves are immensely powerful. Harnessing that energy for grid-scale electricity production would be a major boon to the clean energy industry, but building durable, powerful, and cost-effective wave energy converters has proven difficult. Now though, an influx of federal funding is helping many U.S. companies gear up to test their latest wave energy technologies, giving many in the industry hope that wave power will see massive growth over the next few decades.

How Solar 3.0 Technology Will Change Everything

Energy Efficiency No Comments »

As far as our limited capacities are concerned, the sun is essentially an infinite and renewable energy source. It’s like a giant fusion reactor millions of miles away, illuminating the earth with as much energy as the whole of human civilization uses in a year! So, why aren’t we making more use of such a boundless source to solve all our energy-related problems?
Well, we’re actually pretty close to getting there, and in today’s video, I will show you how!

Solar photovoltaic panels are currently limited to a maximum efficiency of about 30%, and in practice only actually achieve about 20% to 23% efficiency. Now a team in Cambridge has developed a film that can amplify the number of photons that the panel can use, with a potential increase in efficiency to as much as 35%. So how do they do that?
