MIT develops new incandescent light bulb that is cheaper than LEDs

From the UK Telegraph:
Researchers at MIT have shown that by surrounding the filament [in the traditional incandescent bulb] with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through. . . . 
Usually traditional light bulbs are only about five per cent efficient, with 95 per cent of the energy being lost to the atmosphere. In comparison LED or florescent bulbs manage around 14 per cent efficiency. But the scientists believe that the new bulb could reach efficiency levels of 40 per cent. . . . 
But if the new bulbs live up to expectations they would cost under 50p a year to run and even improve health. . . .

My newest piece at the Daily Caller on Obama's false statements during his CNN Townhall

Daily Caller Header
John Lott's newest opinion piece at the Daily Caller starts this way:
I wish that I had been able to go to CNN’s town hall with President Obama. But Thursday night’s event was invitation-only. 
Still, Anderson Cooper, the moderator, challenged the president a few times. But the president just made one false claim after another. 
When rape survivor Kimberly Corban asked why she shouldn’t be able to carry a gun to protect herself, Obama said his current executive actions won’t make it harder for her to purchase a firearm. He claimed, he isn’t proposing anything that “prevents you or makes it harder for you to purchase a firearm if you need one.” 
Obama’s proposed expanded background checks will make guns more expensive, perhaps prohibitively so for poorer people. In DC, where Obama was speaking from, expanded background checks add about $125 to the cost of transferring a gun. 
After the event, CNN brought in conservative commentators such as SE Cupp. However, they failed to understand the issues here. It’s not just that the laws won’t do any good — they will also come with some real costs. These laws won’t stop mass public shootings, but they will hurt law-abiding citizens.  
Then came the issue of expanded background checks leading to a national gun registry. Anderson Cooper said that people are afraid of having their guns taken away and asked, “Is it fair to call it a conspiracy?” “Yes, it is fair to call it a conspiracy,” Obama said, seemingly intimidating Cooper into dropping the subject. . . .
