Temperatures in Tibet rose last year to the highest level since records began for the remote Himalayan country, which scientists say is particularly vulnerable to global warming, state media reported on Friday.
The Associated Press recently reported that at least 27 of 104 nuclear reactors across the United States are leaking potentially dangerous levels of tritium into the groundwater around the plants.
The scope of the problem surfaced after the recent discovery of a leak at the Vermont Yankee nuclear plant. According to the AP, new tests have shown that the levels of tritium in the wells at the Vernon, Vermont site are more than three-and-a-half times the federal safety standard.
“We’ve heard this one before; Obama threatening to sever subsidies to the fossil fuel industry. He called for ending the subsidies during his SOTU, and was doing so even before that. Now, he’s proposing that $36 billion worth of those subsidies for oil and $2.3 billion for coal (both get $70 billion a year in total) get stripped from the budget–which would be great. Too bad special interests will almost certainly keep this from happening.
are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.
Of course, the useful lifetime of a laptop is only 3 years or so before it becomes obsolete so if these batteries do come to market, you would need to be able to remove them and add them to your newest laptop.
can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means laptops and other small devices like mobile phones will run much cooler than with traditional lithium-ion power batteries.
Fantastic, no more laptop burn then!
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic
According to the article, the batteries are dur to be delivered to shops in the next 2-3 years. There is no mention of a price point though – never a good sign!
