Comment Re:Er, that's a bit confusing (Score 1) 166

From Big Pharma's perspective, with the involuntary testing of prison inmates off the table in most Western countries, the homeless population presents a viable alternative who are statistically unlikely to pursue litigation.

From a humanitarian perspective, the quandary is "Do we want to allow the weakest among us to make decisions they are unqualified to properly weigh?"

I will leave the ethics to others, but ultimately, as future consumers of these tested pharmaceuticals, do we want to rely on results that are likely skewed because the test subjects were also taking heroin, methamphetamine, and cocaine?

It's not the companies sponsoring the test that somehow try to pick this demographic. It's the people themselves. Most of the tests pay the panelists, but it's not all that much. For someone with a stable job, the small amount usually isn't worth the hassle (have to be at the test location during business hours several times a week sometimes, keeping logs, or whatever). Not to mention not worth the possible health risks. For homeless/unemployed/etc., that's their electric bill for this month. It's enough money to them that they routinely lie about health conditions, drug use, etc. on the consent forms.

Only way to fix it is to offer substantially more money to panelists.

It sounds like they're only doing this when the network is congested in a specific location. Like they're basically prioritizing slowing down the heavy users when things get busy, rather than everyone. I have a much harder time getting worked up about that, especially when they're waiting until people are out of contract and can easily switch carriers.

I agree that what you describe makes "consent" useless, but you don't necessarily need to outlaw it.

Just require that:
- any commercial entity that stores information on individuals (with NO exceptions whatsoever) has to provide said individuals a full dump of the data once per some time period upon request, with no conditions or cost attached, along with a list of everyone they've given it to.
- the entity must correct any incorrect information, and can't distribute any information regarding an individual until the errors are corrected.

Not perfect, but it would be a start.

Dealers serve a purpose. They need a reasonable profit.

If they serve a purpose, they deserve a reasonable profit. For the life of me, I cannot see what that purpose is. Perhaps you can enlighten us.

Overcharging for maintenance, and conveniently collecting large numbers of scummy sales droids into one location where they can normally be avoided.

I think the best use might just be to eliminate range anxiety. Take your Tesla example - replace 100kg worth of Li-ion battery with 100kg of this new one. Now you have 4/5 the easily rechargeable range (which is still more than most people need on a daily basis), but, as long as the Al battery is stable long term, if you run down the Li-ion, or need to take a long trip, you can keep going. All without increasing the overall weight.

Comment Re:Now it's the grid engineers' problem to solve.. (Score 1) 227

A Tesla S has an 85kWh battery. To charge that in 30 seconds requires 10,200,000 watts of power - approximately the full electrical service to a decent size skyscraper. That's 42,500 amps at 240V, the full maximum power available to over 212 modern homes and a totally impractical amount of current to handle with any reasonable electrical equipment. So while fast-charging batteries are great and a necessary step forward in technology, the universal adoption of electric cars will require not just upgrading our infrastructure, but a complete rethinking and redevelopment of the electrical grid using not-yet-imagined technologies.

It could also be a grid engineer's best friend. You just have to change the way you think about it - the cars would be a *massive* local storage resource. The VAST majority of people are just going to be plugging their cars in overnight at home, and starting with a full "tank" every morning. I could imagine a system where, once electric cars are ubiquitous, most parking lots and cars would be designed so that when you park, your car just automatically gets hooked into the local grid. You set some parameters on the car for min/max charge levels and buy/sell price limits, and suddenly you don't have to worry so much about demand spikes. Demand goes up, the price/kWh goes up, and once it starts passing the "sell" threshold of the local automobile population, they start discharging into the grid. You just tell the car "keep at least X% charge so I can get home." If I show up nearly empty, and there's 1000 other cars in the lot mostly full, they could charge mine without ever making demands on the grid.

Comment Re:Green wave (Score 1) 364

I'm fairly sure in parts of the UK they implemented staggered green lights along busy stretches of road. If you accelerated modestly to the speed limit, or just below, the lights were timed to turn green as you got to them.
Those with lead feet would be accelerating hard, then waiting at the lights as you cruised by.

Actually, no. The problem is, they race by, stop, and then are in your way as you cruise up to the green light, causing you to have to slow down/stop anyway.

Comment Re:How can you search data (Score 1) 90

Well, if you're encrypting, it means the keeper of the data isn't supposed to know what it is, which means they can't do any data mining, selling, etc. of it anyway, which would be where the ability to do queries on the data would be useful. If you're encrypting everything, then all you need is to be able to find the records, and you could use hashed account names or something to index those.

So yes, it would be difficult to search/sort on the encrypted data, but then that's sort of the whole point...

I've always liked the idea of space elevators, but I've also been bothered by a problem that I've never seen addressed, "micrometeoroid erosion". Sure, you can build one. But how long is it going to last, with nothing to protect the main cable/strands/shaft/whatever-you-want-to-call-it from a near-endless --though admittedly low-rate-- series of impacts by speedy dust particles?

I imagine they'd do something similar to how some of the new suspension bridge cables are designed. The main cables are actually cable bundles, and they're made so that individual strands can be replaced if necessary.
