US Nuclear Plants Expanding Long-Term Waste Storage Facilities 187

mdsolar (1045926) writes with news of nuclear plants across the U.S. dealing with the consequences of the failure of Yucca Mountain. From the article: "The steel and concrete containers used to store the waste on-site were envisioned as only a short-term solution when introduced in the 1980s. Now they are the subject of reviews by industry and government to determine how they might hold up — if needed — for decades or longer. With nowhere else to put its nuclear waste, the Millstone Power Station overlooking Long Island Sound is sealing it up in massive steel canisters on what used to be a parking lot. The storage pad, first built in 2005, was recently expanded to make room for seven times as many canisters filled with spent fuel. ... The government is pursuing a new plan for nuclear waste storage, hoping to break an impasse left by the collapse of a proposal for Nevada's Yucca Mountain. The Energy Department says it expects other states will compete for a repository ... But the plan faces hurdles including a need for new legislation that has stalled in Congress." There's always recycling or transmutation.

Comment Tweaking the Greentards (Score 1) 213

He's doing it for the lulz, to tweak the particularly strident greentards that infect Australia.

That said, if Australia went full-bore into PRISM and LFTR development (by, perhaps, providing some funding but mostly just expediting red tape and silencing greenies/NIMBYs) they could very well build a 11- or 12-figure industry around it instead of leaving it to China or India.

Comment Replace them all with LFTRs (Score 1) 323

LFTRs would take up less space, be more efficient, and rather than consuming water for cooling they could use low-grade leftover process heat to desalinate water. So, instead of being a massive freshwater sink it would be a freshwater source for piping inland (or, depending on the site, a river could be reversed for that task?)

Comment H2 fuel cells are a nonstarter, SOFCs may not be (Score 1) 659

No nation is going to build an entire network of H2-dedicated pipelines and other infrastructure, so any sort of mass fueling of H2 will come from electrolysis (consumes freshwater and is expensive for power) or (most likely) reformation of natural gas piggybacking on the already-existing NG infrastructure.

So, how efficient would an H2 fuel cell vehicle be per mpg equivalent worth of reformed H2 from natural gas? How much is the net fuel cost per mile?

Now, IMO a more promising path would be using solid-oxide fuel cells that accept hydrocarbons directly, but IFF they can get at least 16-20kWh out of a gallon of gasoline, its volume and mass are comparable to an I4 or V6 engine, and the cost comes down to 5-10 cents per Watt.

That's been discontinued, and AFAIK only has PC drivers. Their replacement is just a composite -> USB box, but it does have OS X drivers.

Dunno if either has OSS support, alas.

I like the VCR2DVD deck idea, assuming one can be found that does a quality job. I reckon finding a higher-end (S) VHS deck (with 4+ heads, stereo, auto tracking, maybe jog/shuttle knob) and testing it with a few sacrificable tapes is the way to go for OP. For 8mm video I'd recommend finding a Digital8 deck or camera, since it internally converts analog 8mm/Hi8 to digital before sending it up the firewire link.
