    Dear Mr Musk....

    Could we have a development grant please?

      Considering that Elon receives significant amounts of grant money from the government, wouldn't it be easier for this team to just cut out the middleman?

        @Flakk, why are you getting downvoted for this? It's not like it's not public knowledge that he has HUUUGE public money subsidies - calculated to nearly $5 BEEEEEELION. Billion, not Million. Billions are very very big numbers. A million seconds is 11 days, a billion seconds is 31 years. Billions are BIG.

        I take it you don't like musk then, based on you picking out him specifically. Shall we break down what this money he 'received'.

        1.29billion tax incentives to build the gigafactory in nevada, which will be only be seen over the next 20 year period if he employs 6500 people by 2020. So didnt receive any money there, just will be paying less tax, like all other large companies that different states want, and now all companies will be getting - MAGA hey?

        45 million in discounts on a loan of 465m, which the state made money from, by the way ford got a discount on a loan of 5.9billion - MAGA

        90m tax break on manufacturing equipment to reopen the NUMMI plant in Fermont, hiring back the workers that lost their jobs at GM and toyota. - MAGA

        517m selling zev tax credits, not payed by the tax payers but by car manufatures so that they dont get fined for not meeting emissions requirements - MAGA

        284m tax credit on car purchases, this is seen by the buyer, not tesla and applies to all electric vehicles and 38m more from california.

        126m for deploying batteies to help in stablisation of the power grid in california

        750m building solar city, which the state owns on the condition that over 10 years 5 billion is spent on employing 3450 workers.

        1.5b estimated value for 30% subsidy on solar installations, which includes they only grant here of 497m

        5.6m from newyork also in tax incentives for the same thing

        260m in property taxes for solar city, as the state owned it.

        20m to building a spacex launch facility near brownsville

        got tired of putting MAGA at the end, that stupid word, hey how about MEGA, that an actual word, Make Europe Great Again.

        So only 1 grant in there worth 497m, all the others havent been paid to him, the companies, like many other companies get tax breaks for doing things.

      "only gets accepted for publication or considered by journalists after a working prototype is available"

      that wouldn't be scientific, that would be like "flat earth" thinking. Publishing 'unproven' ideas for peer review, PARTICULARLY before having a working prototype, is ALWAYS a good idea. It also helps you to establish ownership [they should get a provisional patent, too].

      I can think of many things that have fallen into the 'unproven' category (at least at one point in time), like Evolution, the Big Bang, nuclear power, Einstein's theories, black holes, and television. In fact, I understand that someone had constructed a model of a color picture tube using sugar cubes, and used THAT to obtain a patent, which RCA allegedly had to license before they could produce color TV picture tubes with multiple electron guns... so yeah, theory shouldn't be restricted from publication until "after a working prototype is available". That's just ridiculous.

      It's also a good strategy to publish FIRST (before you have a working prototype). In this case (as an example), battery makers should NOW 'want in' on their 'iron oxide' design. Some smart battery maker will likely invest some time+money into building prototypes, licensing the design with an really good contract, and maybe even having exclusive rights (for a little while, at least).

      1. Charles 9

        Re: Oh look, another one.

        Publishing to inner circles is one things, especially if the intent is peer review. I'm talking about publishing to the world at large because by my reckoning that's a half-truth (which is in turn twice the lie). My thought is, "If you're gonna sing it, be sure to bring it." Perhaps Beyond 2000 jaded me a bit. I mean, how many of these hypegasms (like holographic crystal storage, which was demonstrated in a lab 20 years ago, IIRC) have gone nowhere (or, like CFCs, turned out to be counterproductive)?

          On the contrary, what we need is MORE people publishing papers - far too often research that fails to produce anything with commercial potential is dumped unceremoniously, potentially resulting in other people repeating the same research.

        IIRC the science of a MOSFET transistor was published in 1928. It took technology another 35 years to be able to produce them. The 1947 development of the point contact transistor was a relatively simple evolution of the crystal radio diode. It was quickly superseded by the junction transistor as the semiconductor processing technology improved.

        In the early 1940s a book was published on the long history of clock technologies. The final chapter described the latest developments using quartz crystal vacuum tube oscillators. The author confidently predicted that such accurate devices would be forever confined to laboratory environments due to their complexity and size.

    Firstly, not sure why the quoted analyst was saying that it was only based on computer modelling, the article mentions 2 teams, one doing modelling and one doing physical experimentation. So what gives>

    Secondly, even if the analyst is right and it takes 10 years to production, and even if in the end the 'production' capacity improvement isn't 8X or even 2X or 3X but an eventual 1.5X, that's a 50% improvement which is not to be sniffed at.

    Current 'touring-type' electric cars like Tesla can do 500-ish km on a single charge, 50% increase brings it to 750-ish which is the limit of most modern diesels. How long did it take ICE car industry to get to that level of range? Having electric cars be able to replicate that within about 15 years is pretty neat

        If battery tech improves so that capacity is increased by 50%, you are not going to get phones that last 50% longer. Instead, you are going to get phones that consume 50% more, owing to more powerful CPUs that run more crap in the background, more powerful GPUs that run pretty animations, and more radios running for more time. Either that, or they'll just make them another fraction of millimeter slimmer. The actual duration of the battery seems to be a pretty low priority.

          I don't agree with Filippo that they'd use these batteries to make phones that draw more power - power draw is limited by the heat output already so we aren't going to get a bigger power budget than what we have today.

          A better battery, more charge for the volume and weight, could mean smaller and lighter devices. Extra processing power often comes with more efficiency. A bit longer life as part of the deal is something that could be easy to sell.

          It may be that phones have become too thin, and that is forcing compromises on details such as the durability of the connector. Compare your mobile with the typical low-cost cordless phones on your landline. They're too bulky, but they don't feel fragile. A bit extra thickness might make a better data/power connector possible.

          Stepping back from the thinness race might make all the difference, without new battery tech.

      You miss the point with cars...

      Adding a larger fuel tank adds less weight to a vehicle than a larger battery. The range of diesel vehicles is limited by the size of tank, and a full tank of diesel still weighs less than a battery of a similar size/range.

      Electric cars have been around a LONG time, they've just only recently started to become popular again. The reason they fell out of favour was due to the weight and lack of range, milk floats were almost always electric because they were quiet and didnt require a long range or high speed etc.

      There's also the consideration of how fast you can recharge, and the availability of charging stations. A diesel car can be filled in a couple of minutes, and diesel is available almost everywhere... A battery takes longer to charge, and in doing so it occupies a charging slot for much longer than a diesel car does. On the other hand, once the infrastructure is in place the power can be transported far more quickly than liquid fuels.

        Furthermore, it's possible to extend that range very easily. If it's for occasional use, a gerry can or two will easily tide you over should you drift away from civilization. If you frequently trek away from fuel stations, it may be worth it to get an additional fuel tank installed.

    It's hard to see where the x8 comes from. The x4 seems unlikely. The x2 is theoretical. Have they modelled impurities etc? Even NiMH vary hugely on quality of materials and the best can equal LiPoly for volume (not weight) after 100 deep cycles. What effect on weight?

    So 5 to 10 years or never sounds likely as does 1.5 to x2 capacity (weight or volume?).
