Comments on: Where federal energy research money should go

The Energy Department's new ARPA-E program aims to find "transformational energy technologies" beyond fossil fuels. Here are some offbeat ideas on how it could get started.

Solar solar solar! Every other form of energy comes directly from there anyway. That's where we get our energy. Go to the source! We need to put all our backing behind solar and batteries as a close second. There have to be so many ways to use the sun's power that we aren't even tapping the surface of.

[joyofsomeone]

Well, all other form of energy except geo-thermal. That's home-grown! :P

Two problems with solar energy: (1) It is insanely inefficient. The best production solar panels get 11% efficiency and the best a lab has done is around 25%. Toyota is considering putting solar panels on the Prius. If the Prius sat in the sun all day long, the solar panel would give it 6 miles. Solar has a LONG way to go before it is even a little bit viable. (2) To make a solar panel you have to do some very eco-unfriendly things.

If solar efficiency can get to 50% then it would make sense to deploy them on rooftops en masse. However, even if solar was the ideal and impossible 100% efficient, then to produce as much energy as a nuclear reactor would take up far more space than that nuclear reactor.

Nuclear is the best source of energy. You have a better chance of seeing a flying unicorn than having a meltdown in this country, seriously. Modern reactors product only 10 cubic feet of waste per year. There is only one problem: people have the wrong perception about them. They picture Chernobyl even though US reactors are different than Soviet reactors. The eco-nuts hate them because they don't want cheap energy. (But they disguise that with propaganda.)

to i_am_stil_wade (below):

Dude, you don't know what you're talking about. Most production silicon PV panels now get 13% - 16% on average and the best done in a lab is %40 (not 11% and 25%). Solar thermal (not PV) are well over 50% efficient in converting photons to electrons. Solar thermal fields already produce electricity on par with coal, and beat coal when you consider levelized costs, and without levelized costs they and are expected to beat the price of coal in the southwest within the next 3 years.

Time to update your research.

Regarding nuclear, yeah, it has it's place, but you need to clue in before you trash solar. A lot has changed.

Are we really short of energy, seeing that we waste so much of it, like leaving lights at every store and buildings in towns, even during the daytime due to a possibility of litigation or whatever?
Why can't we go out to the other parts of the world and build houses, schools, hospitals, and manufacturing shops, and help them farm? Such is the noblest investment, and it will come back to us like a boomerang. We must give them copies of the Bible in their language also, to enable them to stand on a firm ground. They will come to our rescue when we need their help without us asking them to help us.

We don't need to shove religion down their throat.
That causes enough issues and wars as it is.

[davea0511]

monkeyfun14, you have issues.

Try funding the MYT engine from Angel Labs LLC.

Your SUV will get the mileage of a Prius! It is the engine of the second industrial revolution. All engines, pumps, compressors, generators etc will produce much more with a lot less.

The money should go right back into the pockets of the people who earned it. All the government is going to do is waste the money on pet projects of political backers. Why is it desirable to let the government splash cash around on projects that have nothing to do with protecting freedom and following the Constitution? If the government cared about energy and the environment then why is hemp illegal? Is it because we're supposed to do things the hard way? If the government cared about energy and the environment why don't they crack down on polluters right now? This is all a joke and all this money is going to be wasted.

[monkeyfun14]

You would be a perfect candidate to live in a 3rd world country where no money is used for research.

[scdecade]

The top 10 tech companies invest more than $20 Billion a year on r&d. Actually, there's an entire industry devoted to finding innovative ideas, seeding them with money, and giving them business advice on how to best capitalize on their ideas. It's called venture capital and I'm not aware of any 3rd world country with a multibillion dollar VC industry. Go back to grazing on the grass sheeplehead.

Because some research has timescales that are too long and risks that are too high for commercial enterprises to want to invest in. That is where government funding comes in. There is a role for both sides, it doesn't need to be an either/or thing.

America should fund reactors that are safe and don?t melt down. In his open letter to the President Obama, the climatologist Dr. Jim Hanson recommended the Thorium fuel cycle and the Liquid Fluoride Thorium Reactor (LFTR). Dr. Edward Teller, the father of Fusion, after a lifetime of work on every aspect of nuclear technology had at the end of his life come to this conclusion in his final study: the LFTR is the best of all possible reactor types.

The LFTR, which is currently in development in France, Japan, and Russia, is a very simple, efficient, and elegant type of reactor. It can start up on any kind of nuclear fuel, bomb material, or nuclear waste product to produce very high temperature heat and at the same time breed more fuel in the bargain. This thrifty approach to nuclear energy greatly appeals to me, but I became even more interested in the LFTR when the details of a new patent were revealed by Dr LeBlanc (see below @ minute 53). It opens up the possibility of building a very compact but powerful reactor that can run for 30 years without refueling. With no danger of a core meltdown or runaway reaction, it can be operated remotely in an unattended fully automated intrusion detecting mode and sited underground while it breeds self perpetuating new fuel within the thorium structure of the reactor itself.

In order to get to its fuel, U233 that has been produced inside the very solid metal walls of this 200 ton reactor containment vessel, a proliferator must destroy and disassemble the reactor, lift its heavy reactor core out of a 100 meter deep reinforced aircraft crash proof hole in the ground, then cut the thorium containment vessel up into small pieces while enduring heavy killing gamma radiation exposure, next reprocess these reactor pieces using isotopic separation since the U233 is denatured with enough U238 to make chemical separation of bomb grade U233 impossible, and do all this without being detected. Now, this is a tall order for any proliferator and may just be an impossible assignment.

At the end of the service life of the Lftr, the reactor vessel is sent back to the factory where it is reduced to liquid fluoride salts that become the feedstock of a next new Lftr. This feedstock can only be used by the new Lftr and not for bombs. A few handfuls of waste products are held at the factory for a few hundred years to cool down before they are mined for the many precious elements contained within like platinum and iridium. Now that is what I call a safe, efficient and thrifty mode of operation!

LFTRs are indeed an interesting solution, but Rubbia's energy amplifier is better I think. A lead-cooled, solid fuel reactor does no require the complex chemistry that LFTR needs, but still burns 232Th/233U and minor actinides, and requires an achievable spallation driver, which in addition allows greater flexibility in neutronics over those coming from the fuel alone.

Bussard's Polywell Fusion Project is getting minimal funding from the Navy as they crunch out the numbers from the last phase of research; hopefully they will get funded for the next scale-up research since it is looking like electrostatic-confinement fusion is getting close (~10 years) to production scale. Unless there is something drastically wrong with the laws of physics as we currently know them, it *should* work. Given that most of the Bussard work is out in the open it would be a shame if the US ends up having to buy fusion reactors from another country for lack of proper funding in a *natively-developed* technology. (And yes, other countries *are* looking into electrostatic-confinement fusion.)

If you want a low-cost "moonshot" solution there are many far worst investments than what it will take to finish Bussard's work and nothing with a higher potential payoff.
N-O-T-H-I-N-G.
Might as well swing for the fences, especially since the cost is so low.

Cold fusion is closer to commercial reality than most people realize, and much closer than plasma fusion. It has produced thousands of times more energy per gram of fuel than any chemical reaction, and it can probably generate millions of times more. In some experiments, it has reached temperatures and power density comparable to the core of a conventional fission reactor.

There has been tremendous opposition to cold fusion because of academic politics. This opposition should have stopped 19 years ago, after nearly 100 laboratories first confirmed that cold fusion is real. Serious funding for this research is long overdue.

For lots more information on cold fusion, see LENR-CANR.org. I do mean LOTS more: a bibliography of 3,500 papers and several thousand pages of very boring scientific papers and books.

>Cold fusion is closer to commercial reality than most people realize

Hehehe ... I think you're confusing commercial reality with commercial scam reality. Fyi ... it ain't even a laboratory reality.
