Energy Saving Bulbs

[simes]

Nope - they can lead to epileptic symptoms and they are a really cold light.

Until they sort the epileptic stuff, I won't touch them.

Not that I suffer, but someone close to me does and even if you're not a sufferer, it can still induce.

I've replaced most of the bulbs in our house and swapped the CRT's out for their LCD counterparts. I guess I've saved about £100 off my electric bill. Which is good as the whole lot only cost me £2000

I save energy by huddling round a hand-made candle formed from my own earwax.

Energy saving bulbs?

Just take the bulb out, sorted!

We have a relatively large garden - does anybody have one of those heat pump things? Are they any good and how much did you pay for it?

I wonder how much energy it takes to dig the 10 feet deep hole to bury the pipes?

Just tell the kids that you've buried some sweets down there and get them to dig it for you.

It's easy enough to integrate in terms of potential energy (mgh), but humans aren’t particularly efficient diggers. Pumping one Kg of water from 2 metres would take around 40 Joules (2Kg * 10 m/s^2 * 2 m) working at 100% efficiency; so perhaps double that in practise. If done in one second continuously it’s about the power of a 40W bulb, and about what’s used by the human brain IIRC. Humans aren’t particularly efficient thinkers.

Oops, I pumped 2 Kg (~2 litres) of water above, not 1.
