there's often some unknown technical magic happening when moving from high-grade uranium to low-grade uranium that requires no extra enrichment

I think you meant the other way around. Yes. It is called the Zippe centrifuge. Russia, Pakistan, China, France use this process and the USA is currently switching to it for uranium separation. Back when France still used gaseous diffusion the process was itself powered using nuclear power plants at Tricastin which are now not required and can be devoted to grid power. BTW separation can theoretically be even more efficient and the USA is currently testing an Australian technology called SILEX.

I suspect that if we had actually allowed nuclear reprocessing R&D to be done for the past 40 years the so called nuclear residue issue would be irrelevant. Processes like SILEX probably have promise helping with that. Problem is no government is interested in having such a low power and tunable isotope separation method like SILEX becoming commonly available. For some reason it was made an US secret despite being originally developed in Australia with minimal university level funding. Do they really think no one else can independently reinvent it? Australia is a country with 23 million people.

There are plenty of projects for modular nuclear power plants the problem is lack of funding. Eskom had one called the PMBR and Terrapower has another called the TWR.

Try reading about the Atari-Amiga deal. It sounds a lot like this deal.

Atari made a loan to Hitoro to develop the computer. With the option of buying it afterwards when it was completed. But Atari, under Tramiel, decided it was better to let Hitoro sink with the development costs and get the Amiga for nothing extra - basically they would foreclosure Hitoro to 'pay back' the loan they made. The founders and partners of Hitoro would lose all the money they invested in the process. Thankfully Commodore bailed Hitoro out just in the nick of time.


Two Google Engineers Say Renewables Can't Cure Climate Change 630

_Sharp'r_ writes Two Stanford PhDs, Ross Koningstein and David Fork, worked for Google on the RE<C project to figure out how to make renewables cheaper than coal and solve climate change. After four years of study they gave up, determining "Renewable energy technologies simply won't work; we need a fundamentally different approach." As a result, is nuclear going to be acknowledged as the future of energy production?

It is an edge bet against a future where petrofuels are too expensive. With declining oil prices electric cars and hydrogen cars are going to start becoming less attractive just like what happened in the 90s last time this was attempted. Tesla might still sell with their angle on performance. These guys will probably not sell well at all. Plus cost effective ways to produce hydrogen without using petrofuels or natural gas have never actually materialized. One way is high temperature nuclear power plants using thermoelectric water separation but given the current investment into nuclear technologies it is not going to happen. Another way was concentrated solar thermoelectric but that is not cost effective with current methods.

The USAF wanted to launch heavier satellites to higher orbits than the Shuttle could do. After the Challenger disaster and the cancellation of the Shuttle-Centaur the USAF and NRO had no other choice but to use the Titan rocket, which was really expensive, to launch these payloads. Things like reconnaissance satellites and things like that.

I think Microsoft bought it because they thought they would get the cellphone market share of Nokia with the deal plus any patents Nokia had. The patents were the main deal here. The problem is Nokia market share collapsed after Elop and his burning platforms memo. No one wanted Windows in their cellphone.
