LOHAN ideas..

Re: Tracking by telescope.

Manual telescope tracking is unlikely to work , but automatic telescope tracking could be used if you are using the right tracking scope, usually the camera is set to track a pinpoint light, but in this case I'm sure a white sphere could be tracked against the blue sky if you were to play with the camera software a bit...

Hemp used to make graphene-like supercapacitors

Re: ENERGY density, not power

Article is confusing Energy and Power the two links say:

" is its maximum power density, a measure of how much power a given mass of the material can produce. At 60 °C, the material puts out 49 kW/kg; "

And:

"At a very high power density of 20 kW kg–1 and 20, 60, and 100 °C, the energy densities are 19, 34, and 40 Wh kg–1, respectively. Moreover the assembled supercapacitor device yields a maximum energy density of 12 Wh kg–1"

The all time altitude record for a foxbat is 124kft or 37km Space ship 2 will go beyond the Kármán line at 100km (which is 328kft - you might recall Spaceship One's tail number was 328kf for this very reason)

NASA-backed fusion engine could cut Mars trip down to 30 days

Too many Errors

"compress lithium or aluminum metal bands around a deuterium-tritium fuel pellet to initiate fusion."

"A pellet the size of a grain of sand " - if you ignore the compression bands

"mean that the spacecraft could power itself on solar energy alone." - if you ignore the compression bands and fuel pellets.

So it needs fuel pellets, and new compression bands for every pulse, So it most certainly can not function "on solar energy alone".

When you can do this without wasting the compression bands then it'll be more interesting. I don't know how you could do this though, other than going back to Solar powered laser confinement, maybe Lasers Are the answer.

Nexus 1 put in orbit to prove 'in space, no one can hear you scream'

Scream

Of course they'll hear it scream, the microphone and speaker are physically attached. Only when totally separated by a vacuum will they not hear it. They would need two satellites.

Tesla vs Media again as Model S craps out on journo - on the highway

Re: Question for the crowd

"It's bit unfair to isolate the vehicle from the end-to-end environment impact of the entire fuel chain."

Yes it is isn't it. So here's a really good US govt report on oil refinery energy consumption. That is refining only, when you consider drilling, shipping, and overland transportation to forecourts, the old analogy of 2 barrels in for every barrel out, isn't that far from the truth. So even if you power an EV from a dirty coal power station it's still cleaner than an wheezy ecobox that claims 99g/km but in reality has already burned more than that in refining, production, shipping etc.

As for practical, the Tesla Model S in the story is a SEVEN seater (watch the video here) perhaps you are confusing it with something else?

Oh *all* the car shows? that would be except this one then? what about the papers? Oh.. I don't need to be convinced, I already own one..

Re: Question for the crowd

Just to continue that hydrogen point: 85kWh in hydrogen is 55 Litres, as fuel cell is 50% efficient to match the Tesla's 300 mile range would be 110 Litres. At 70Mpa in a pressurised Round Tank, Which goes where exactly? its a 24" diameter sphere, or you could squash it to a 40" diameter rounded pill.. So how much space did you need in the car?

Question for the crowd

Gasoline is typically 36MJ per Litre - meaning 85kWh = 8.5 Litres

But 8.5 Litres would typically only get you 70 miles in a gasoline car (37mpgUK 29mpgUS)

In the Tesla 85kWh will get you 300+ miles

So a gasoline engine runs at 4.3MJ per mile, whereas the Tesla uses 1MJ per Mile.

Gasoline engines usually max out at 35% efficient. Whereas an electric motor is more like 90%.

The interesting point is when you bring in Hydrogen in at 5.6MJ per litre (compressed at 70 MPa) and run it through a fuel cell at 50% efficiency to drive a 90% efficient Motor, it becomes obvious how stupid Hydrogen is as a fuel compared to battery EV.

Re: Measurement unit?

kWh is also available in J (Joules) or eV (electron Volts) or cal (calories) or even kg·m^2 s^−2 (Si Base) - feel free to choose.

'Leccy-starved Reg hack: 'How I survive on 1.5kW'

Re: too easy@Parax

I'd only really recommend MicroCHP if you needed the heat and had battery storage to charge up with the power, microCHP is not a good generator, hence not my first suggestion for Spain. The fuel cells are being installed and are working very well if you have a clean gas supply.

But if you want to go back to basics there's always the Mains Gas Generator .

Re: too easy

Or fuel cells... Fuel cell for mains gas or even micro chp

Re: too easy

That or a proper off grid system, with deep cycle batteries.

too easy

A shed full of lead acid batteries an Inverter (and why not some Solar panels for a free daytime top up?) will solve most of your problems.

That square QR barcode on the poster? Check it's not a sticker

Really?

How is this a problem? Which barcode scanners AUTOMATICALLY take you to the destination? the one I use DOESN'T, This is deliberate choice on my part, It will show me the data and then ask me what I want to do. This really isn't much of a problem.. If I don't like the url I won't open it, same as anywhere else. Do you click url's sent to you by text message? I don't. how about urls in random tweets.. nope.. same with QR codes, scan look and decide.
