質問:
太陽光励起レーザーを発振する媒質には、クロム、ネオジム、イットリウムといったレアメタルが使われているそうですね。これらのレアメタルを巡って世界中で激しい争奪戦が繰り広げられていますが、レーザー発生装置を大量に作れるほど、資源は十分にあるのでしょうか?
回答:
  
質問:
太陽光励起レーザー発生装置は、本当にランニングコストがかからないのでしょうか?
太陽光自動追尾システムを動かすためのエネルギーや、(特に砂漠では)レンズの清掃コストはどうなるのでしょう?
回答:
  
「低コストで超高温を実現する『太陽光励起レーザー』」で紹介したように、太陽光励起レーザーを使えば、単純に太陽光を集光するよりもはるかに高い温度を実現することができます。
下の動画は、2009年1月に東京工業大学の屋上で行われた太陽光励起レーザーの実験風景です。この時出力されたレーザーの出力は50W。この程度の出力であっても、0.1mm厚のステンレス板にいとも簡単に穴を開けることができてしまいます。
さらに次の動画は、太陽光励起レーザーで酸化マグネシウムを還元しているところです。レーザーの焦点が酸化マグネシウムの表面に合ったときに、煙のように蒸発するマグネシウムが見えます。製錬を商業化するにはまだ不十分な出力ですが、酸化マグネシウムの還元自体は可能であることがわかります。
  
「レーザーでマグネシウムを製錬できるか?」という記事では、酸化マグネシウムにレーザーを照射することで粉末表層が蒸発し、金属マグネシウムだけ取り出せることを紹介しました。
下の動画は、1kWのレーザーを酸化マグネシウムに0.5秒間照射した様子を、1/60で高速度撮影したものです。レーザーによって酸化マグネシウムは一瞬で気化しますが、この時、気化した物質は垂直に立ち上ります。そのため、気体から特定の元素だけを比較的容易に取り出せるのです。
現在、蒸発して回収した物質のうち、30%が酸化マグネシウム、70%が金属マグネシウムです。つまり、純度70%のマグネシウムをレーザーで製錬できています。マグネシウムを燃料として使う場合には、70%の純度でも十分です。ちなみに、ピジョン法でも最初に製錬されるマグネシウムの純度は80%程度で、それから高純度化の処理を行っています。
  
質問:
太陽光励起レーザーを使った場合のMgOからMgへの変換効率(現状/目標)はどれぐらいですか? プラントの試算からするとかなり高そうですが。
回答:

炭酸ガスレーザーでマグネシウムを製錬
私たちは太陽光励起レーザーで400W〜lkW級が達成できたとして、実際にマグネシウムを得ることができるのか、別タイプの実用レーザーを使って実験を行っています。400W/1kWの炭酸ガスレーザーを酸化マグネシウム粉末に0.2秒間照射すると、粉末表層が蒸発、そのガス中の30%がマグネシウム原子であることを確認しました。ここで重要なのはどれだけ効率よく純粋なマグネシウムを作れるかという点にあります。できたマグネシウムの燃焼で得られるエネルギーを生成にかかったレーザーのエネルギーで、割った値を「エネルギー還元効率」と言います。これが大きいほどよいわけですが、実験データから求めた値は45%で、目標値50%にかなり近い成果を得られています。

千歳の太陽光励起レーザー実験装置

20000°C相当のエネルギーを与えれば、触媒なしでマグネシウムを製錬できます。しかし、20000°C相当に相当する膨大なエネルギーを投入することは可能なのでしょうか?
子ども時代に、虫眼鏡を使って太陽光を集めて紙を焼いて遊んだ経験は、みなさんにもおありでしょう。ただ、集光によって実現できる高温には理論的な上限があります。それは6000°Cです。つまり、いくら太陽光を集めても、その発生源である太陽表面の温度を超えることはできません。けれど、人間の知恵を活かせば、さらに温度を上げられます。それが、「太陽光励起レーザー」です。

This Fourth of July : from President Barack Obama

【出展】:私へのメール :      info@barackobama.com;  


This Fourth of July


matuoka --

The Fourth of July is especially dear to my family. For us, it is not just our nation's birthday. It is the day Michelle and I became parents 12 years ago. And I can't wait to watch the fireworks with Malia on her birthday tonight, as we do every year.

As we celebrate the profound pride of being American, today is a time to honor the women and men in our armed forces, whose immeasurable bravery and sacrifice have made our country what it is today.

That sacrifice is shared with husbands and wives, with sons and daughters, with fathers and mothers, who are asked to wait at home as their loved ones protect our nation. Their heroism, too, has helped pave the path of our freedom.

Even before we moved into the White House, Michelle was a champion for those military families. She has witnessed their struggles, and she has made it her personal mission to fight for them. On this Fourth of July, she recorded a personal message, commemorating our nation's birthday and paying tribute to these families.

Watch Michelle's message.

Please take a minute to watch Michelle's video -- and join us as we honor our military families here and abroad:

From all of us, happy Independence Day.

Thank you, and may God bless America.

President Barack Obama

On to the Senate : Mitch Stewart (info@barackobama.com;)

On to the Senate  

2010.7.2


matuoka --

Last night, just before 7 p.m. Eastern Time, the House passed Wall Street reform by a vote of 237 to 192. This is a huge victory for our movement -- and all American consumers.

Now, there's just one hurdle left before this historic bill can be signed into law. It must be passed by the Senate -- a vote likely to come right after the July 4th congressional recess.

Protecting consumers and holding the big banks accountable is a key piece of the change that all of us fought for in 2008. It's up to us to bring it across the finish line -- making sure every champion in the Senate knows that we're standing with them, and that those in opposition know that Americans are demanding reform.

Can you take a moment now to write to your senators?

Thanks for making it possible,

Get it to the President                2010/7/1




matuoka --

Congress is expected to cast its final votes on historic Wall Street reform as soon as today.

So much has happened in the past year that it's easy to forget how much OFA supporters have done to get to this point.

In key districts around the country, we organized to win a 223-202 vote in the House last December. OFA supporters poured in nearly tens of thousands of calls to Capitol Hill offices the day before last month's vote to get it through the Senate.

This is your bill -- the strongest and boldest overhaul of the financial system since the aftermath of the Great Depression. It's the change we fought the big banks to make -- and we've almost won.

What happens before these final votes will determine if this once-in-a-generation legislation makes it to the President's desk. That's up to us. We need to make sure the champions in Congress who've worked with the President to pass this bill know we're supporting them -- and that those in opposition hear our call for reform.

Tell your representatives you strongly support Wall Street reform -- and that they'll have your thanks if they do the same.

Congress is about to cast its final votes on Wall Street reform. Write your representatives.

Reform will increase security for all Americans by forcing credit card, mortgage companies, and predatory lenders to play by the rules instead of exploiting consumers with hidden fees and pages of fine print.

It establishes a new, independent agency -- the Consumer Financial Protection Agency -- whose sole job is to protect consumers. And it ensures American taxpayers will never again be asked to bail out the big banks that are "too big to fail."

But these changes will only happen if the President can sign it into law. We all need to get the bill to him.

Write a letter to your members of Congress now:
