New Wave of Fusion and Robot Innovation at MIT 90
An anonymous reader writes "Popular Mechanics has been getting some great access inside the labs at MIT all week, and they've gotten some interesting looks at developing technologies. Robot-assisted rehab with gaming-style controllers comes out of the biomechanics lab, blind and crash-proof UAV testing with F/X cameras is being done at the aerospace controls lab, and work on electric scooters with super-cheap assembly is proceeding at the Media Lab. Perhaps most exciting is a fight for funding while the holy grail of clean fusion power in reach at the plasma center. The article on fusion predicts, "We'd see economically feasible fusion power by 2035, at the earliest, and increasingly efficient commercial reactors somewhere in the middle of the century."

RoboScooter - Clean, Green Mobility for Today's Crowded Cities
The RoboScooter is a lightweight, folding, electric motor scooter. It is designed to provide convenient, inexpensive mobility in urban areas while radically reducing the negative effects of extensive vehicle use - road congestion, excessive consumption of space for parking, traffic noise, air pollution, carbon emissions that exacerbate global warming, and energy use. It is clean, green, silent, and compact.

I worked for two years at General Atomics trying to model and understand the interaction of fusion plasmas with the reactor walls. I've seen people here who have done more.
Like many other people who have worked/are working on fusion, I don't think it's going to be commercially viable this century. The problem is materials. It's simply too expensive to build these things.

That isn't a hydrogen economy.
A hydrogen economy is using renewable but intermittent sources of energy to make & store the hydrogen, then burning the hydrogen in an efficient fuel cell in your electric car, along with other efficiencies such as regenerative braking.
There is no carbon in the cycle at all
And what exactly are "renewable but intermittent sources of energy" you may ask?
The answer is any, or all of the following:
(1) Solar
(2) Artificial photosynthesis (eliminate other steps in the process
(3) Wind turbines
(4) Wave energy
(5) Tidal energy
(6) Waste heat (say from a smelter or from a microbiological sewerage treatment plant) coupled with the new high-efficiency thermal engines
(7) Crop waste burn-off
(8) Deep Ocean Thermal Energy
(9) Geothermal
Any source of flaky, "unreliable" (in the sense that it might not be there the exact moment you need it, and it might be abundant when you don't need it) renewable energy is viable in a hydrogen economy. That is because storing the energy as hydrogen removes the imperative of having a power station that can produce "energy on demand".

In any case it has nothing to do with conspiracy theories or blaming fellow scientists. The fact is, basically nothing aside from Tokamak research is funded at a significant level.
