Debate: Does the world need nuclear energy?

Alternative Energy No Comments » Nuclear power: the energy crisis has even die-hard environmentalists reconsidering it. In this first-ever TED debate, Stewart Brand and Mark Z. Jacobson square off over the pros and cons. A discussion that’ll make you think — and might even change your mind.

TEDTalks is a daily video podcast of the best talks and performances from the TED Conference, where the world’s leading thinkers and doers give the talk of their lives in 18 minutes. Featured speakers have included Al Gore on climate change, Philippe Starck on design, Jill Bolte Taylor on observing her own stroke, Nicholas Negroponte on One Laptop per Child, Jane Goodall on chimpanzees, Bill Gates on malaria and mosquitoes, Pattie Maes on the “Sixth Sense” wearable tech, and “Lost” producer JJ Abrams on the allure of mystery. TED stands for Technology, Entertainment, Design, and TEDTalks cover these topics as well as science, business, development and the arts.

Awesome Low Head High Flow Grid Tie Micro Hydro 530 watts!

Alternative Energy No Comments »

I travel to a summer home in the mountains of Western North Carolina to meet Bill. He has come up with a way to pull a lot of water over a dam and into a permanent magnet alternator. He feeds the power to the house to supplement what is used. Bill is using Langston Alternative Power for his setup and makes around 500 watts.
The interesting thing about this micro hydro setup is the way that the system is started. There is a lot of water that needs to flow over a dam. To get this system going Bill uses a simple shop vac to pull the water over into the 6″ pipe.

No batteries or charge controller is needed. Simply a grid tie limiter inverter.

Micro Hydropower : Turbulent Turbines

Alternative Energy No Comments »

Hydropower has been with us for millennia, but the 20th Century race to build huge centralised hydropower dams in many parts of the world has caused untold environmental damage. Now a new micro-hydropower technology is working with the natural flow of water and wildlife rather than against it, to bring much needed constant baseload power to off grid areas in remote areas of developing nations.

Geothermal Energy Could Heat Homes And Reduce Our Dependence On Fossil Fuels | Mach | NBC News

Geothermal energy uses the natural warmth below the surface of the Earth to heat water which can then be used to heat houses. It’s a clean and reliable. But, can there ever be enough buy-in to use it to radically change how we power our world?

Rain Gutter POWER #1 – How to Harvest Free Energy From Your Roof with a Hydro Electric Generator!

Alternative Energy No Comments »

A lot of people wonder if there’s any power in the rain falling on our roofs. This video series starts with the theory of how much power is available then attempts to achieve it in practice. It was a lot of fun to BUILD, hopefully you enjoy it and learn something in the process.

For those in the comments that insist I didn’t compensate for the angle of the roof in the rainfall calculation, did I not say “once I calculate the horizontal distance…”?

Thanks for watching…


Harvesting hydro power from rain gutters! It sounds impossible but it works. This is part 1 of a video series on the theory and implementation of capturing hydro-electric power from the roof. For part 2 click here:
