Comment: Isn't the issue more about energy storage? (Score 1) 176 176

It seems to be that storage of energy is really the more critical factor. If we focused on something like rotational fly-wheel storage systems that would be a better strategy. To be able store terra watts of power for weeks or months at a time would be ideal. Then solar would be able to just feed into that store. Of course the engineering challenges of keeping a large disc spinning at high RPMs would be immense I suspect.

Comment: But why is there only one spot like this? (Score 2) 45 45

Isn't the whole point of this area is that is anomalous? at least in comparison to all the other areas of the CMB? yes there are other 'cooler' areas but this seems to be the only one of this magnitude. If this was a common feature across the whole CMB then the cold spot could be considered as part of the standard cosmological model surely?

Comment: Scale issues (Score 2) 137 137

I still think the scale of human mars missions are too small. They need to first develop the engineering to make rotating spacecraft to produce around minimum 0.376 g ( mars gravity), but 1 g craft would be more helpful longer term. To be rotating at less than 1 rpm to avoid nausea means a radius of over 200metres though. But at least with that set up there is more potential living/storage space. The more living space the more people and isolation becomes less of a problem. The larger scale the more protection (especially against radiation) and redundancies of systems can be in place in the event of failures along the way. Ultimately you want a long term project that goes back and forth from Mars to Earth on a regular basis. Something like an extension of the ISS.

Comment: Insurance and registration (Score 1) 362 362

The concept of a full autonomous driving car is still really far way, I estimate in the range of 20-30 years or even more. My understanding is that current autonomous vehicles don't cope with rainy or unknown conditions. The more interesting aspect would be how augmentative safety technologies might reduce insurance premiums, or even reduce certain kinds of legal requirements. For example if your vehicle has auto assisted braking could that allow some one to drive at a different alcohol limit range? It might be that autonomous vehicles at first must be licensed to travel on specific routes. So you would have to register your autonomous vehicle only on specific routes you have 'taught' it first. Only then you could allow it to be 'autonomous' and be able to pay no attention while being transported ( i.e. you don't need a license to be in the vehicle).

but what if the basic income allows people to generate things? those people are not necessarily idle. The idea of a basic income is that they don't have to 'worry' about income. So they can go and focus on doing something they enjoy like create art, make an app, write a book etc, that they can potentially sell and supplement their basic income. You could receive a basic income and still get paid to get contract work from time to time for example. Most people want to be creative or engage in society in some way, even if it just contributing to the social spaces they operate within.

This is something called the metric expansion of space. The metric value is changing at a local level where the measurement is taken. I think it is misleading to talk about space as a dimension moving at some speed, because speed is really distance per unit time. the expansion of space is just space per space changing. We tend to embed our explanations as if the universe expanded from a point on a piece of paper, it doesn't really work that way, the paper in a sense is being generated as it goes along. The speed of light is just some measured velocity value that happens to be pretty close to c when we measure it at various places around the universe, light goes through the metric of space. The metric of space doesn't really say much about what that speed is. So c just goes along the metric as the metric is generated.

Comment: Isn't the block chain what makes it decentralised? (Score 1) 281 281

Isn't the point of bitcoin is that the block chain is decentralised? i.e. everyone has a copy of it? does it matter who mines the coins as long as the coins end up distributed around? also can't the bitcoin protocol just be tweaked by the developers or something?

Comment: not knowing what education is for (Score 1) 335 335

I think he would have been better to use the money to set up training programs for skill sets that are useful to society, particularly infrastructure aspects like plumbing, electricians etc. May be use the money to set up in school programs for really specific things like programming, or target specific types of students to figure out what they might excel in.

All the simple programs have been written.
