Nuclear Energy: Abundant, Clean, and Safe

Alternative Energy No Comments »

If you truly want to save the planet from global warming, there’s one energy source that can do it. It’s not wind or solar. It’s not coal, oil or natural gas, either. So what is it? Michael Shellenberger, founder of Environmental Progress, has the answer in this important video.

Script:

France gets 70% of its power from one carbon-free source. Sweden 40%. Switzerland 36%. The United States 20%.

For those who wish to create a world free of carbon emissions, France is clearly the role model. 

That source of energy, by the way, is not solar or wind. It’s not coal, oil or natural gas, either.

It’s nuclear. 

Nuclear energy is not only cleaner than all other forms of energy. It’s also cheaper to create, abundant and safe. 

Yes, safe.

So, if the world is going to end in a few years because of global warming due to rising CO2 levels, why aren’t we going all out to produce this abundant, clean and safe form of energy? Why aren’t there dozens of nuclear power plants in development all over the world? 

Well, we all know the answer, right? Nuclear energy is just too risky… too dangerous.

So, even though we’re told we’re facing an “existential crisis”—which means humans may cease to exist; even though we might all wither away in unbearable heat; or starve because of world-wide droughts; or drown in rising seas; or be killed in Mad Max-style riots—nuclear energy is off the table… because… it’s too darn risky. 

Hmmm.

I want to be sure I have this right. The goal is to save humanity…There’s a way to save humanity…And we won’t take it. Because we’re afraid, there might be a bad accident… or something. 

Does that make sense to you? Because it doesn’t to me.  

But maybe I’m not giving enough weight to the safety argument, so let’s take a closer look at that since no one, not even the most radical environmentalist, disputes that nuclear power produces massive amounts of energy cleanly and efficiently. 

Safety, like everything else, is a matter of context. So, here’s some context. 1.4 million people die worldwide every year in traffic accidents, 2.3 million in work-related accidents, 4.2 million from air pollution. Deaths directly related to nuclear power? Under 200—not annually but in the entire history of the nuclear power industry. 

But what about those famous nuclear disasters we’ve all heard so much about? Didn’t they poison untold thousands? Three Mile Island in 1979, Chernobyl in 1986 and Fukushima in 2011. 

Okay, let’s deal with each one.  

Three Mile Island:

There was an accident at the plant, yes, but the amount of radiation that leaked was no more than one might receive taking a chest x-ray. The Nuclear Regulatory Commission acknowledged as much four weeks after the initial media hysteria died down. “We goofed,” the commission told Congress.  “There was no danger of any hydrogen explosion.” But that didn’t grab the headlines. 

Chernobyl: 

The accident developed into a catastrophe only because of pitiful safety procedures unique to the Soviet Union. It would never have occured in the West. Even so, initial reports of radiation leakage turned out to be grossly exaggerated. According to the World Health Organization, “As of mid-2005”—that’s 19 years after the explosion—“fewer than 50 deaths had been directly attributed to radiation from the disaster.” 

Fukushima:

In 2011, as a result of an earthquake and tsunami, the Fukushima Nuclear Power Plant was destroyed, and nuclear radiation was released. Yet, despite the media hysteria, not one person at the power plant died because of radiation leaks. The deaths that occurred in the area were the result of the tsunami. 

Well, what about nuclear waste? Surely that’s terribly harmful. 

Actually, no. All the nuclear waste ever generated in the US can fit on a single football field stacked less than seventy feet high. It’s easily and safely buried in steel canisters encased in concrete.

Major breakthrough on nuclear fusion energy – BBC News

Alternative Energy No Comments »

European scientists say they have made a major breakthrough in their quest to develop practical nuclear fusion – the energy process that powers the stars.

The UK-based JET laboratory has smashed its own world record for the amount of energy it can extract by squeezing together two forms of hydrogen.

If nuclear fusion can be successfully recreated on Earth it holds out the potential of virtually unlimited supplies of low-carbon, low-radiation energy.

The experiments produced 59 megajoules of energy over five seconds, more than double what was achieved in similar tests back in 1997.

Nuclear power was a major discovery of the 20th century. Today, it continues to play an important role regarding the future energy mix, climate change, innovation, and proliferation. In fact, we observe an increasing interest in nuclear power to combat fossil fuel emissions and climate change. Bill Gates, Microsoft Co-founder and philanthropist, is investing in so-called “new” nuclear technology, and Frank Thelen, a well-know German VC investor, consiers nuclear power sustainable and a key for decarbonization. So do some countries, like China, Russia, and the United States. Even the Fridays-For-Future movement (FFF) is engaged in this discussion.

In this TEDxTUBerlin talk, I take a different position. As an industrial engineer and political economist, I deploy an interdisciplinary approach: I provide technological arguments, in combination with economic analysis and I address the long-term dream about the “potential” of nuclear power that prevails since 1945, but in reality has never come true. Prof. Dr. Christian von Hirschhausen is a German economist and currently the chairman of the Workgroup for Infrastructure Policy (WIP) at Berlin Institute of Technology (TU Berlin). This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx

Going Six Feet Under – Tapping into Geothermal Energy: Jim Bose at TEDxOStateU

Renewable Energy No Comments »

Oklahoma State University Professor Jim Bose is using a device from the 1800s to conserve energy and save residents a lot of money. Bose explains how geothermal heat pumps may cost a little extra to install, but the long-term effects are well worth the conservation and economy stimulation.

In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

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…”?

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:
